LADYWALK  RESERVE,  BREEDING  REPORT 2021

By Richard King

Introduction

This is my sixth consecutive breeding report for Ladywalk and as the years progress it is easier to see patterns of birds’ presence and breeding, with the counts (Appendix One) being particularly useful. I have continued to split the reserve into 12 transects and my methodology was again to list all birds in each transect by sound or sight on each visit. The reporting details that follow are largely from my notes, plus information from other sources such as regular users of the reserve using the reserve’s Whats App and Twitter accounts. We have been again provided with much information from the ringers, notably about the success or otherwise of tits and other species in the nestboxes. I am sure that there are other peoples’ breeding records that can enhance this report. If so please forward them to me via Richardking54@gmail.com.

The vast majority of the information in this report relates to the Ladywalk reserve, accessible to members through the locked gate via a coded padlock. Whilst the Bourne and Blythe Meadows are regularly observed and reported on by Ladywalk visitors, and some tree planting and working on drains to flood the area has been done, they are not included in this report.  It would add much to our local knowledge if another volunteer came forward to survey and record the breeding activity in this area.

 The transects on the reserve remain the same as previous years and are as follows –

Transect 1 – from car park to the double gates, technically not part of the reserve but treated as the reserve in this report.

Transect 2 – from double gates to Hide A.

Transect 3 – at Hide A

Transect 4 – from Hide A to Rudd Hide *

Transect 5 – at Rudd Hide

Transect 6 – from Rudd Hide to Riverwalk Hide*

Transect 7 – at Riverwalk Hide

Transect 8 – from Riverwalk Hide to Bittern Hide*

Transect 9 – at Bittern Hide

Transect 10 – from Bittern Hide to B Hide*

Transect 11 – at B Hide

Transect 12 – from B Hide to Lock Up inc. the  fishing pools*

*Or vice versa

The full visits were normally between approx. 8am and early afternoon and were dated –

Weather

In 2021 with one exception we escaped serious flooding on the reserve. After several days of rain the 25th May saw flooding which seriously affected the sand martin nests and  we experimented with a tape lure which attracted birds to the artificial sand martin bank adjacent to their nests near Rudd Hide. The rainfall on the above date contributed to May being the wettest month in this breeding season.  Sand martins were affected by these floods but there was little evidence at this time of other breeding species being affected. 

April in contrast was one of the driest on record but also very cool with overnight frosts, indeed it was the “frostiest” April for 60 years. It is thought that the low temperatures affected breeding success.  For example tits hatched in mid / late  May but food for the nestlings was hard to come by as the caterpillars had not hatched due to the cold, so nestlings starved.

June saw some hot and humid weather initially but there were longer outbreaks of rain towards the end of the month. The path at the north end of the reserve was barely passable and flooding at B Pools resulted in some wader chicks drowning, notably the two little ringed  plover chicks.  July was wetter with  rainfall higher than average during this month, with some heavy showers but there was no serious flooding on the reserve. Temperatures were near to 30 degrees on occasions. In contrast rainfall in August was the second lowest over the five months covered by this report.

A  detailed summary for the 2021 breeding season

Canada Goose: During April nests were being seen across the reserve including possibly on a raft on B Pool. Interestingly three eggs were found on one of the rafts when it was being cleared in October. The first broods were recorded on 12 May when three sets of goslings were on the reserve (CW). On  19 May these were probably included in the   broods of six and  five goslings at B Pool, and on the 25 May there were two broods of  five on the same pool. On 17 June there was a brood of eight on the path between Bittern and B Hide,  a brood of seven at B Pool and six on the river.

On the basis of this information there were about five broods on the reserve, a similar number to 2020.

Grey Lag Goose:  These were rarely seen during the breeding season on the reserve.

As usual there was a large post-breeding flock on the reserve, probably originating from Marsh Lane where large numbers breed. 

Mute Swan:  One pair successfully bred on New Bay and on 8 June parents and five cygnets were first seen and remained. They also bred elsewhere on the reserve with 2+7 seen on 14 May, and on subsequent dates, from Riverwalk Hide. It is clear that  there were two broods originating on the reserve this year.

Egyptian Goose: These birds (a pair) were at A pool on 14 May and were occasionally seen on other dates. They are non breeders here but as they breed elsewhere in the Tame Valley it is likely that similar will happen here.

Shelduck: As in previous years a pair was present at both pools on dates in April, May and June. However they had disappeared by mid June. It is possible that they attempted to breed but were flooded out but there is no specific evidence to back this up.

Shoveler: Pairs were present throughout April and into May but not recorded on my visits beyond 17 June. They have successfully bred here in the past but no evidence of breeding this year. They may have been flooded out.

Gadwall: Pairs were present throughout the season on the pools, including the Angling Pool on 4 May, and river. The first brood of ten ducklings or more on the reserve were seen on  7 June (PS) and there was a brood of this size on the river the following day.  On 17 June when a brood of nine small ducklings were seen on B Pool, matched by another brood also with nine ducklings. On the following day there were reports from Main Pool of broods of eight, six and three. On 3 July there were broods of six and seven seen from Bittern Hide and there were a number of larger ducklings at the same location. Also at B Pool PS reported broods of nine and six at B Pools on 12 July.

On the basis of this number of broods and the dates it is likely that there were 7-10 broods this year which is more than last year.

Mallard: Continues to breed in good numbers and the first report of ducklings was on 1 April from PL with a family of six ducklings at New Bay. The same brood or another was reported two days later and on  9 April when there was a brood of ten at New Bay which attracted the attention of  a sparrowhawk. Shortly afterwards on 13 April there was an adult with three small ducklings on the river and ten days later at the same location there were broods of six small ducklings and one adult with four youngsters. Possibly this same brood was seen here on 30 April. On 17 May there was a brood of seven large ducklings on the path and this stretch of river held a pair with eight small ducklings on 8 June.

Families and nests are widespread across the reserve. For example the river beside the entrance track (T1) held a pair with two medium sized ducklings on 19 May and on 8 June there were three broods here of two, four, five. Adults were regularly seen in the ditch that is the length of the boundary beside Sainsburys and a pair nested in an adjacent owl box.

The river between Rudd and Riverwalk Hides had the following broods –

1+6 medium sized on 4 May

1+4 large ones on 14 May

1+3 small ones on 19 May

1+5 small ducklings on 1 July and possibly this same brood was seen on 9 July

1+2 medium sized ducklings on 12 August

This list highlights that ducklings are rarely seen on the pools, with broods presumably feeling safer on the river where it is easier to be obscured from predators. This also applies to the more secluded angling pools, where there was a brood of at least four ducklings on 19 May. I also encountered a mallard’s clutch of eggs on the path beside the pool on 25 May but by the following visit all that was left were egg shells.

Teal: Small numbers were present through the summer but as usual there was no sign of breeding.

Tufted Duck:  Pairs were regular on the reserve pools and river throughout the spring and summer. In 2020 I reported that the first brood was reported on the early date for this species of 24 June whilst this year the first brood of three was reported from Angling Pools on 12 July and in August broods were reported on several dates including broods of eight and nine being photographed.

Broods were also reported on 27 July (1+3) from B Pool, where there was a brood of seven on 12 August and the following day two more (8 and 9). On 20 August on the river  seven small ducklings were seen, and on the same date there was a brood of six large ducklings, also on the river by the copse.

These records suggest that there were at least six broods produced on the reserve, probably more than in 2020 and considerably better than in the period 2015-19.

Goosander: this is a  well reported species, that has increased in breeding numbers over recent years. The ringers recorded three occupied nestboxes during their visits in April. Broods are regularly if not exclusively  reported on the river and the numbers quoted probably account for nests between Water Orton and the reserve. By 30 April six broods were being reported  and in mid May PS was reporting eight broods totalling approx. 70 ducklings.

More specific records include five ducklings on the river on 26 April and four days later there were 1+3 also on the river. There were ten ducklings on 8 May on the river and a week later 17 were on the Blythe (PF) and on the theme of large broods there were 15 large ducklings on the Tame island.

Common Pheasant: Regular on the reserve particularly under the feeders but my visits yielded no sightings of families or juveniles. A number of predated eggs were located by the angling pools. It is therefore pleasing to record CW’s sighting of  pheasant chicks near to Bittern Hide on 24 June.

Little Grebe:  This species was rarely seen on Rudd Pool despite its comparative seclusion but there was a family present with up to four young on dates at the end of July (WT). Birds were more regular at Main and B Pools. At the latter on 13 April there appeared to be three pairs and there was a pair there on 4 May. A juvenile was reported by CW on 17 June and there were reports of a fledged bird in late June / early July, possibly the same one. On  23 July PL reported a brood here and four days later  1+1 were present and possibly another brood was also heard.

The angling pools appear to be the best location for breeding related activity for this species where PS reported a brood of three on 12 Jul. A brood was  reported on 27 July and I saw adult sized young on 12 August and I suspect that all these records relate to one family.

It is difficult to estimate how many pairs nested this year, and how many birds fledged and on the basis of the above figures I suggest four to six broods.

 Great Crested Grebe:  Birds were present throughout the survey on both pools.  On 4 May one was showing interest in a coot’s nest although they nested on an island where three young had hatched by 17 May. It is likely that two pairs nested on Main Pool as another nest was identified on 19 May  with two eggs (PL) with a bird sitting on the nest on 8 June, suggesting that two pairs attempted to nest here.

On B Pool there was a pair demonstrating courtship on 6 April with a nest in reeds seen from 23 April which produced three young birds, seen on a parent’s back on 17 May. These three were seen for several weeks but by 17 June there were two young that fledged.

Bittern: with two pairs successfully breeding at RSPB Middleton there is a need to be aware that birds may spread to other reedbeds in the Tame Valley.  In 2021 there were no positive reports about birds booming on the reserve but there is a need for visitors to the reserve to be alert to this possibility.

Cormorant: nested in the same location as in recent years and during my visits I made regular counts from Hide A concluding that there were approx. 31 nests this year. My counts were much higher than last year when there appeared to be 21 nests. By mid May many of the nests held nestlings that eventually found their way to the main pool. There seem to juveniles constantly in nests, suggesting that they are two brooded.

Grey Heron:  as the summer progressed juveniles were seen on the reserve from one or two local heronries as was the case in previous years.

Little Egret: this species was regularly seen across the reserve and river but there was no evidence of breeding or roosting. There appeared to be no interest in the cormorant colony.

Sparrowhawk: as referred to earlier, one was seen to attempt to take a mallard duckling at New Bay.This species has bred during the last three years near to the lock upand I saw a bird and heard one here on 30 April. I also heard feint calls, probably this species, on 8 June. A juvenile was seen in the same area on 14 June and on 17 June calls were heard, presumably from the nest.

Buzzard: this species is  regularly over and heard off the reserve  but again there is no evidence of breeding which considering the size of the reserve and its trees is again disappointing.

Water Rail: the area in front of B Hide is the favoured breeding ground for this species and I saw one here on 6 April and heard one on 8 June. The evidence of successful breeding by this elusive bird was an adult with at least two young on 8 June (PS) and the same observer sighted a second brood with two small ones at the same location on 22 June. With up to ten birds heard on visits to the reserve in autumn 2021 it is likely that other pairs bred elsewhere in the reedbeds making this a successful breeding season.

Moorhen: this species is a regular breeder across the reserve, starting with Keyhole Scrape. On 23 April there were two small young birds which were regularly seen into May. By the 19th  there was only one juvenile and this survived. This scrape’s position beside a well used hide means that it is well watched which meant that a second brood was identified by 17 June when there were two newly hatched young, which became one on 3 July when we had two parents and two differently aged juveniles on the scrape.

Rudd pool had two juveniles present on 12 August and Main Pool held two adults and three small young birds viewable from Riverwalk Hide on 27 July. This became 2+2 by 12 August.

There was evidence of breeding at B Pool as follows –

1+4 in front of B Hide on 25 April

2+1 on 8 June

An adult with a small chick on 30 August.

The angling pools remain a safe place for breeding, with the fallen trees providing ample

nesting sites so no surprise that there were two / three small chicks on 12 August. This area is secluded so I suggest that there was more breeding activity than this.

Despite predation of chicks it appears that 2020 was quite a good year for this species with evidence of fledged juveniles in several places..

Coot: the most numerous and easily identified nester on the reserve. This year there was no nesting activity at Keyhole scrape but Rudd Pool held at least two nests. The first was  identified on 23 April and on 6 May there were two adults and two young here and at least one bird fledged.  There was a further nest viewable in July and in mid August there were juvenile moorhens and coots on the pool.

Main pool records were as follows –

Bird with nesting material on 13 April.

Nests are easy to locate from the elevated status of Riverwalk Hide and the maximum at any time was five on 14 May.

A pair and three young on 25 May and 2+3 on 8 June.

Two broods, one of three young, the second of one on 17 June.

A fully fledged juvenile was with its parents on 3 July and six days later there were three

juveniles of the same size, seemingly the survivors of three broods.

At B Pool up to three nests were seen from Bittern Hide and on 19 May two small juveniles were sighted. On 25 May 1+3 small young were seen, on 8 June there were  broods of two and five and  on 3 July there were two juveniles of contrasting ages.

Nests were also seen from B Hide and on 17 June four broods were counted (4,1,2,2).

Finally, this species successfully bred at the angling pools, the evidence being adults and a hidden brood there on 17 June.  It is likely that there was more breeding activity than this.

In conclusion whilst a lot of nests have been recorded  it again appears that a significant proportion of the young birds seen were predated. It would be useful to have any records of this in the future.

Oyster Catcher: again regular on the reserve and again did not successfully breed. A pair nested on the usual island on Main Pool, being sighted on the nest on 6 & 23 April. After this date they appear to have deserted the nest although one or two birds were present in May and June. The nest was very close to a Canada Goose’s nest and their presence may have contributed to the desertion.

Lapwing:  in 2020 it was estimated that there were two broods from which birds fledged which was the best return for several years. 2021 surpassed this!

On 23 April PS was reporting two nests on the marsh opposite Riverwalk Hide. These nests were again seen on 4 May and by ten days later there were up to four chicks in this area. Chicks were not always easy to see from Riverwalk Hide, due to the long grass rather than predation, as PS was reporting six chicks from two broods here on 18 June.

B Pool did better, a reflection of the earthworks that created new scrapes in 2019. On 6 April a nest was seen from B Hide and on 23 April there were five nests in the area of B Hide and this species progress at B Pool is as follows –

Three lapwing chicks in front of Hide B on 4 May.

1+2 by Hide B on 14 May. In this area three chicks were seen swimming to higher ground when water levels were high.

A pair on the scrape  hatched four by 17 May.

6 chicks from two broods seen 19 May.

On 24 May PS reported four broods at B ((4,3,3,2), with another trio of chicks at Main Pool. He reported that seven broods had hatched by 12 June.

15 lapwing chicks were counted  on 17 June and many of these survived.

This was probably the best year for breeding lapwings at this reserve. It was significant that predation levels were low and it is thought that this was due to the numerical presence of this species, and common terns as well, dealing with threats such as from crows and lesser black backed gulls. There was very little presence of the latter species this year.

Little Ringed Plover: this species was present throughout the breeding season at both pools, particularly B Pool where there were up to six during April and May. They nested on B scrape with a nest seen on 25 May when there was also a family of 1+2 reported by PS who also sighted 1+2 on 18 June. Additionally he reported three newly hatched chicks here on 7 June, with two chicks seen the following day (CW).   Sadly none of these young birds survived a flood on 28 June and whilst later in the summer young birds were observed on the reserve they originated elsewhere.

This is the second consecutive year that chicks have hatched and then been flooded out which has led to reserve management looking to seek quotations for sluices and similar to be installed on the reserve.

Redshank: birds were regular on the reserve during |April and May with a pair seen mating from B Hide by GA on 13 April. There were also two mating on 30 April and birds were subsequently frequenting an area of thick grass by B Pool. It was thought that there were two pairs nesting here and on 17 June I saw four birds mobbing a heron which suggested the presence of chicks. PS reported one chick, “the first to have hatched on the reserve for decades”, and ten adults on the following day. However during the flood of 28 June one young bird was seen to swim to safety across B Pool and this bird progressed to fledge. This was probably the juvenile seen from Riverwalk Hide on 9 July.

It is not known how many birds hatched, and were predated or flooded out but this  first breeding success for this species at Ladywalk confirmed the success of the work to create the B Pool scrapes several years ago. .

Black-headed Gull: this species is ever present on the reserve and river and we seem to be nearer this bird breeding on the reserve. To evidence this a pair took up residence on a raft during April, and were seen to mate on the 23rd and remained in residence throughout the summer.  They did not breed there, neither did the three pairs recorded by PS elsewhere on B Pool on 18 June.  It is possible that they were put off by the presence of the lapwings. On 3 July there were young birds on the reserve, and likewise on subsequent dates, but these were not reared on the reserve. Possibly in 2022?

Common Tern: after a three year absence this species bred again on a raft on B Pool. A pair was on a raft by 14 May, with two pairs on the two rafts five days later. The successful nest was on the raft nearest B Hide with three young there on  21 June (CW) but by 1 July there were two chicks (PL). On 13 July these were being fed away from their nest which confirmed their success.

Feral Pigeon: are  regular on the reserve but there was no information as to whether they used any of our nestboxes this year.  They nest locally on man made structures such as Whitacre waterworks and the bridges over the Tame.

Stock Dove:  Numbers appear stable on the reserve with the line of poplars on the Sainsburys side of the reserve being the main nest site and the marsh being a regular feeding site. Their normal nest site is a hole, such as in the aforementioned poplars, but they also continue to use the owl boxes on the reserve. The ringers inspected the boxes on several occasions, ringing five pullus in three boxes, with reports of two other nestboxes being used.  It would be interesting to know how many birds nest in natural holes in addition to the reserve nestboxes and I would estimate that  there are approx. eight pairs on the reserve.

Wood Pigeon:  As usual this species was constantly on the reserve, where it is sure to have bred in several locations. No nests or young were seen / reported but nos. appear to be stable.

Cuckoo: This species appeared more numerous on the reserve in 2021 with the maximum reported being six including two females on 31 May by PS.  The first bird calling was on 30 April and on most of my visits there were at least three calling on or near the reserve. On 8 June I saw a female and heard two males and I estimated that four birds were present, but other birders thought that the maximum was six in June.  This year birds also appeared to be calling later in the summer than previous years, with a female’s call heard on 3 July and six days later a male and female were encountered.

There were several reports of  at least three young birds with BE reporting a juvenile flying from the reeds by Hide B on 19 July. There were sightings and photos of reed warblers having to cope with the demands for food from their “foster bird”.

Barn Owl: this species is doing well in Warwickshire through the regular use of owl boxes with several pairs known about in the Tame Valley.  Ladywalk assisted this due to a nestbox beside the Tame being used, resulting in three young. At a second box the remains of a dead young bird were found on 4 June, that box having been taken over by Stock Dove.

Tawny Owl: these have been regularly reported during autumn 2021  in the woodyard area . However there were none encountered by me, and no reports of birds throughout the survey period. It would be  unusual if they did not breed on the reserve.

Kingfisher: was harder to come by  in 2021 than in previous years. On 17 June there was a noisy bird below the riverbank between Riverwalk and Bittern Hides, which is where they nested in 2020. Single birds were also in this area on 3 July and 20 August so whilst there was no specific evidence of breeding here it is most likely.

I heard a bird at the river by Rudd Hide on 9 July but compared with what I recorded in 2020 sightings were sparse and I believe that one pair bred in or on the reserve, down from two last year.

Lesser Spotted Woodpecker: I did not see or hear this species on or near the reserve this year. There was speculation that two pairs may have bred, such as  in the poplars on the reserve and in the area of  Whitacre reserve.

Great Spotted Woodpecker: these are regular across the reserve, but possibly a slight decline compared with 2020. A nest was located in a poplar in transect 10. Young were heard calling from this on 24 May and GA saw them leaving the nest a few days later.  Elsewhere on the reserve, on 25 May the ringers reported a nest in the ringing area. Young were heard in a nest in T12 near to the hellebores on 17 June, and were still in the nest at the month’s end.

As usual juveniles turned up at the Hide A feeders, the first being fed by an adult on 17 June, the precursor for many reports including two juvs. on 27 July (PL).

I suspect that there were probably about six nests again in 2021.

Green Woodpecker: Ladywalk does not provide the ideal habitat for this species. They are more likely to be encountered at the north end of the reserve (T10) due to the meadowland over the river, and in similar habitat of the Bourne Meadows over Fishery Lane. On the reserve, similar to the stock doves and other woodpeckers, they are likely to be near the poplars. They were heard or seen near them on 8 & 17 June, and two were encountered near the reserve entrance on 29 July.

I had more encounters in 2021 than the previous year but  the only information about successful breeding  was a report on What’s App of three young in the bramble patch near to the aforementioned meadows.

Kestrel:  rare on the reserve and most likely to be seen near or over the river  such as on 1 July when one was near to the copse. Further downstream one was being mobbed by a crow near Bittern Hide on 13 April. Of greater interest was one sitting on the nestbox by the river near to the sluice on 23 April.  This appeared to be a suitable nest site but by 14 May it had deserted and replaced by goosander.

Not covered by the report, one was also regularly seen on the wires by the Bourne meadow so whilst it is clear that there was no evidence of breeding on or near to the reserve one or two pairs nested over the river, at the latter location and at the north end of the reserve.

Hobby: this species was not encountered by me during any of my breeding season visits to Ladywalk and this year after the breeding season there appeared to be less visits to hunt dragonflies or martins.  It is hoped that they bred reasonably near to the reserve but there were less reports of juveniles on the reserve.

Peregrine Falcon: as in previous years birds were reported from Hams Hall Distribution Park and the reserve. On 9 July up to two juveniles were present and it is assumed that they were reared on one of the warehouses or factories.

Jay: this species continues to breed at Ladywalk but possibly in smaller nos. Family groups and juveniles were sighted, such as a report from PS that he had 1+3 on the reserve on 25 June. There were two juveniles at transect 8 on 3 July and six days later there was a family party at T12. This is the angling pools area and was the transect where they were most often seen, such as on 13 April when there were four together.

 It is possible that on these figures there may have been two or three breeding pairs on the reserve.

Magpie:  regular across the reserve and its presence is prob. taken for granted by visitors. They bred, for example a bird was at its nest just off the reserve, above the public footpath between the car park and entrance gate (T1).

Jackdaw: again this year, birds were regularly seen from Rudd & Riverwalk Hides on the marsh (eg eight there on 6 April) and often seen flying from the trees behind the cormorant colony. They probably bred here and a bit of exploration is needed to check this.

Carrion Crow: regular across the reserve and whilst there were no specific reports about breeding this must have occurred. I noted a pair at T4 on 6 April and there was a likely nest in a poplar over the path on T12, recorded on 17 June. This is close to a successful nest in 2020 when I estimated  4-6 breeding pairs across the reserve. It would

be useful if we had more firm evidence of this species breeding on the reserve.

Raven: arare visitor to the reserve, I only encountered one at T10 on 13 April. They would have bred locally I have no evidence that they bred on the reserve or the adjacent meadows.

Coal Tit: I heard one on both 6 April and 23rd at T2 and PS reported a family not far away, behind Hide A on 25 June.

The other stronghold for this species on the reserve  in 2021 was T12 with birds heard three times in April, and twice in May.

It is possible that two pairs maximum nested on the reserve. 

Marsh Tit: I  had no evidence nor reports of this species on the reserve in 2021 so it is possible that they no longer breed  here.

 Willow Tit: much work is being done to encourage this declining bird on the reserve but unfortunately there was no clear evidence of successful breeding this year.(http://www.tamevalleywetlands.co.uk/willow-tit-project/)

Birds were heard calling and seen in spring on many occasions, with Transects 8 and 12 being the most regular locations in my experience. At the former (behind Riverwalk Hide) I saw a bird with nesting material on 1 May and that appears about as far as the records went about breeding this year.

Blue Tit: There were reports from the ringers about their nestbox monitoring and ringing on the reserve this year for this species and those last year: see the ringers’ returns below.

Blue Tit,                2021                      2020                           

Number ringed:     87                          108                 

Number of nests:  14                           16                   

Average:                6.21                       6.75 nestlings per box

These results were a little disappointing and will reflect the cold spring. Additionally there were a further eight nests that had been abandoned for various reasons, this number is higher than in 2020 (five).

From my observations for blue tit, the first family I saw out of the nest was on 25 May which seemed early. It is interesting to note that whilst the sand martin “bank” (smb) was not inhabited by sand martins, tits were seen entering the holes on several occasions during April. There were possibly two holes being used on 23 April but the outcome of any breeding is not known.

Great Tit:

The nestbox records for this species are as follows –

Great Tit,              2021                       2019                                       

Number ringed:      65                           55                 

Number of nests:    11                           10                 

Average:                  5.9                        5.5 nestlings per box 

During my visits I saw more great tits at nestboxes than blue and the first family was sighted on 8 June.

Sand Martin: this species was first recorded on 6 April in the main breeding area by Rudd Hide when about 20 were present. They were regular in this area throughout April but on 4 May they appeared to have been flooded out and then kept a low profile here over the next few weeks. On 25 May we ran a tape of sand martin calls from the smb and there was an immediate response with birds circling the box, holding on the its face and briefly entering the holes. This has led to a decision to run the tape throughout the 2022 breeding season in an attempt to tempt them away from the adjacent riverbank.

Birds then attempted to nest again in this area as on 17 June they were gathering nest material from the path.

On the other part of the river where this species nests (T8) on 13 April  they were showing interest in part of the bank that is collapsing, perhaps because the riverbank is soft. It is possible that this area was not affected by the higher water levels in May, which as stated at the beginning of this report was the wettest month. Birds that nested in both locations after late May did produce broods.

Swallow:   this is an assumed breeder in the stables and associated buildings across the river, which is a good area for young birds to flex their new wings as they fly up and down, as was evident as the breeding season progressed.

House Martin:  small nos. of this species over but did not breed at the reserve. This species was congregating with sand martins on 6 May after they had been flooded out two days earlier.

Cetti’s Warbler: this bird continues to increase across the reserve as evidenced by new areas being colonised, such as to the right of the path as we walk down to the reserve gate (T1). On 9 July there were two / three singing birds in the area of Rudd Hide and the most birds heard or seen on one of my visits was 12 on 4 May.

16 new birds were ringed this year inc. 12 juveniles and again I would estimate about ten breeding pairs on the reserve..

Long-tailed Tit: is regular and widespread on the reserve and there were a number of reports of  family groups. There was early nesting activity in the bush below Hide A, which interested the photographers but it is possible that the birds did not successfully breed there. The first family, with 12 youngsters, was photographed by GA at T12 on 22 April and I saw eight at the same place four days later, hopefully four youngsters had not perished in that time. On this day a family of about eight young birds were at T4 and there were other families recorded on six occasions spread over six weeks, suggesting that some of these were second broods.  Numbers appear to be stable –between five and seven breeding pairs?

Willow Warbler: my view is that this species has declined on the reserve due to changes in habitat (trees grown too large, not enough scrub) and global warming (their range has moved north). In 2019 the species was only recorded by me on four occasions, whilst in 2020 I encountered the species on six survey visits, inc. two on 2 July.

However  2021 saw a brighter situation as I encountered birds on 12 of my 14 visits with the max. being eight on 30 April. However only two adults were ringed and six juveniles which was the only information specifically about breeding. It is possible that about  two pairs bred on the reserve.

Chiffchaff: as in the last two years the highest number encountered during my visits was 13, in April and July, and families were noted on 17 June (T6) and possibly on 3 July at T12. On 14 May a bird was regularly entering an area most appropriate for a nest at T2.

As is the case every year there seemed be a lot of contact calls from this species across the reserve in July / August and this would have been a combination of local breeders and passing birds.

Sedge Warbler:  the highest count of birds seen / heard across the transects was ten on two of my consecutive visits in April / May. This is higher than last year but

 there are consistently less sedge warblers than reed on the reserve. They were most regular by the bund between Bittern Hide and the sluice where they would have bred.. Probable families were seen at T10 on 9 & 27 July.

The ringers report lower numbers of birds ringed this year, 26 adults and 25 juveniles, which are a lot lower than those in 2020.

Reed Warbler: there are parts of the reserve where this species is numerous, notably below Riverwalk Hide where there were eight on 9 July and in front of B Hide where as usual they bred. On 27 June there was a likely family in Transect 4 (near to Rudd Hide) and another family was also noted elsewhere on 27 July. Nos. of birds seen on my visits varied with 21 seen or heard on both 3 & 9 July, which suggests passing migrants. On most visits reed warbler outnumbered sedge.

Reed warbler ringing returns were again phenomenal with 54 adults and 110 juveniles ringed ( in 2020 it was 60 and 118). Of interest was that in 2020 38 birds were ringed before 14 July and our conclusion was that these were likely to have been reared on the reserve. This year that no. was three and it is felt that this reflects the fact that first broods were generally unsuccessful, this could easily be due to the cold April. So whilst early breeding success was poor this would have been compensated by the success of second broods. Due to the stability of adult bird numbers my estimate remains that

10-12  pairs bred on the reserve this year.

 Grasshopper Warbler: one of the highlights this year was the ringing of two adults and two juveniles on the reserve and this was evidence that they bred on the marsh. They were reported as regularly calling on the reserve in 2021, compared with 2020, and the lateness of their song suggested two broods.

We continue to work on the marsh and meadow area to provide what we believe to be their suitable habitat.

Blackcap:  again thiswas the most numerous summer visitor across the reserve with 27 birds encountered on  8 June and one less on my previous visit 25 May. There were a further four visits with 20 or more birds. Transects 1 and 2 tended to have most birds: on 8 June I found a family at T2, whilst on 3 July I found a family at T1 and a probable family on T2.

The ringers report ringing 65 birds inc. 54 juveniles.  This is a much lower total then last year when it was 147 birds in total.  From my numbers in the chart I again suggest 15-20 pairs across the reserve again this year.

Garden Warbler: between one and eleven were recorded on 10 visits (4 dates had 11 birds) and this species is increasing across the reserve as these were greater numbers than in 2020. I am unsure whether this is a reflection of the reserve, or this species is doing well globally.

The only evidence I found of successful breeding was on 8 June when there was a very agitated bird near Riverwalk Hide, this suggesting the presence of young birds. I would suggest that the higher numbers that I have recorded are reflected in a higher no. of breeding pairs, say about five breeding pairs across the reserve.

Lesser Whitethroat: for the third consecutive year I had only one record this year, hearing one from the car park on 25 May. An adult and juvenile were ringed on the reserve. However it is unlikely that they bred on or near to the reserve but they may have nested on the meadows across Fishery Lane, as hinted by the above record.

Common Whitethroat: it would appear that nos. on the reserve are similar to those in 2020 with the top number being 12 on 8 June.  Notwithstanding this during the summer I felt that there was more evidence of this species over the river, and less on the reserve, but the nos. don’t back this up.  Families were regularly seen: on 9 July two families were seen between Rudd and Riverwalk hide, (T8)  where courtship had been reported on 14 May. Juveniles were seen by me on 9 July and 20 August  at Transect 6 (between Rudd and Riverwalk Hides).

The ringers’ report  that they  ringed 11 adults, as well as 28 juveniles but it is difficult to understand where those young birds hatched.

Goldcrest:  my evidence is that this species was more widespread across the reserve in 2021 than last year. Birds were regularly seen or heard at T6 as is usual, that being around the hollies by the copse by the river. They undoubtedly bred here and another hotspot for this species was around the fishing pools near where the roller is kept. Birds were also quite regularly located near to the ditch by the angling pools and on the basis of this there were at least three breeding pairs on the reserve, probably more

Wren: again the most numerous woodland breeder on the reserve, with the most heard or seen being 45 both on 23 April and 8 June (compared with 30 in 2019 and 36 on 28 May 2020).  The ringers reported a nest within a nestbox but were unable to examine its contents for fear of damaging it. The 50% increase over three seasons did not lead to more sightings of families on the reserve –

25 May – family sighted behind Riverwalk Hide

27 July – family at T1.

Allowing for the increase in this species I estimate 25-30 breeding pairs.

It is likely that the habitat management and the lack of cold winters will lead to further increases in this species at the reserve.

Nuthatch: This species seems to be declining on the reserve with little evidence of birds on the reserve in the breeding season. On 17 June there was a family present by transect 1. The other transect where birds were heard or seen was T10 (the poplars) and an adult plus four were behind B Hide on 2 June (PS).  These two areas were their strongholds last year as well and on the basis of this I would again suggest two pairs bred.

Treecreeper:  In contrast to the above bird this species is doing very well, no doubt benefiting from the poplars on the reserve, and the tendency of their branches coming away, leaving splits in the trees’ structure.

The birds’ regular sightings were in the same positions as last year and included in the trees by the gate to the reserve where there were two on 30 April and 19 May. They almost certainly nested here, backed up by juveniles being seen nearby on 9 & 27 July.

Birds were also regular on T10 by the brook between the sluice and B Hide with three seen within 50 metres of each other in the poplars on 23 April, a few days after a nest had been filmed on a mobile phone.

T 12 was another strong area for tree creepers with four heard there on 27 July but birds are likely to be heard anywhere across the reserve . The species is stable, or increasing and I again estimate 4-6 breeding pairs on the reserve.

Starling: are not commonly seen within the reserve in the breeding season. I saw one on 4 May at the entrance to the ringers’ area, and I was subsequently informed that a pair nested in a tree nearby, which has happened in previous years

Blackbird:  widespread across the reserve partic. in the wooded areas. The most birds seen or heard was 24 on 17 June, the same figure as 2020. I recorded no families or juveniles with the exception of a juvenile at Hide A on 12 August but this species is holding its status on the reserve so my estimate of 15 pairs is probably accurate.

Song Thrush: after noting a perceived increase of this species in 2020 I did specific counts this year, with seven the maximum encountered on 19 May, and six on 17 June. Most birds counted were in song.

Encouragingly there were reports of successful breeding with a juvenile seen by me at T6 and in August PS reported that a nest in the woodyard had produced three fledged birds. I will again estimate 3-5 breeding pairs.

Robin:  maximum  birds seen / heard was 22 on 14 May and this is higher than the maxima of the last two years. On other visits recorded nos. were between 4 and 16 and this demonstrates an increase in the population. This accounts in an increase in juveniles seen –   

  • juveniles at T1 on 17 June and 3 July, and probably linked to this was GA seeing a family being fed at the car park two days later.
  • juvenile seen at T2 on 25 May and juveniles were on the track here on 12 August, suggesting a nest nearby.
  • 27 July, a juvenile in front of B Hide
  • 12 August  – there was a noisy family by the fishing pools (T12)

An additional record to substantiate breeding was a bird gathering nesting material, and entering brash the other side of the brook.  This is an increasing breeder at the reserve, like the wren, with  an estimate of 12 – 15 pairs.

House Sparrow – this species is seen more regularly, on the river side of the reserve, but there are records of its presence on the reserve such as on 19 May at T8, this by no means a unique record.  There was no evidence of breeding on the reserve and they are likely to be associated with the stables and houses over the river, from where reserve visitors can hear them

Dunnock: the most recorded  was 12 birds on 19 May and 27 July and nos. averaged about 8 so there may be a slight increase in nos. on the reserve. On 5 July GA reported young being fed in the car park and I saw a juvenile from Rudd Hide on 27 July, near to brambles, a preferred nesting plant. On 6 April there was a pair at T2 in good nesting habitat and on 19 May birds were prob. breeding in brambles at T6. Birds were regular on the track down to the reserve and invariably a pair were under the Hide A feeders. On the basis of my figures  I estimate at least ten pairs across the reserve.

Grey Wagtail: these are an ever-present on the river and there was evidence of breeding as usual. In 2021 the area where they were most often seen was T6 ie between Rudd and Riverwalk Hides Three or four adults were on the far riverbank by the stables on 13 April.  On 14 May there was a pair together on the transect and two juveniles were seen  on 8 June. Single juvs. were also seen in the immediate area on 17 June, 27 July and 20 August.

There was a lot of grey wagtail activity in this area so possibly two pairs bred in the vicinity. With the exception of an adult + juvenile by B Pool on 25 May, seen from B Hide,  the first date a juvenile was seen, I found no more grey wagtails.  Last year in addition to birds at T6,  I recorded juveniles at the bridge by the car park, and  by the outflow (“concrete sandbags”) on the far bank (T8).  With this in mind  I estimate that three pairs bred on the river adjacent to the reserve.

Pied Wagtail: this species was often located quite near to the grey wagtails with T6 again being where it was most regularly seen. There were two males on the river behind Rudd Hide on 30 April and on 14 May there was an adult here.  On 25 May there appeared to be two broods present on this transect, each with two juveniles. Or was it one brood of four that became separated?  Additionally, on 8 June a juvenile was on the roof of the sand martin “bank”, very close to Rudd Hide.

This species was also regular at B Pools and an adult and juvenile were seen from Bittern Hide on 25 May, and also two immature birds were at this pool on 17 June.

There were less sightings of juveniles this year than last and they were less far reaching on the reserve. I am inclined to say that there were 2-3 breeding pairs.

Chaffinch:  whilst birds are quite regular at the Hide A feeders in winter and early spring this species is not common on the reserve in the breeding season. Song was heard quite often,  such as in the area between Rudd & Riverwalk Hides on two dates in April and in the riverside willows in T10 on 8 June. The copse including the holly trees in T6  would be a  good nesting area but unlike last year when a family was reported there has been no evidence of breeding on the reserve.  Information to the contrary would be useful.

Bullfinch: I had no encounters with bullfinch during my surveys which highlights the decline in this species at Ladywalk, but there was  a report from PS of a family between Rudd & Riverwalk Hides on 25 July. I suspect that this family were not reared on the reserve but across the river, possibly by Fishery Lane where bullfinches are regularly seen. Last year I stated that bullfinches are regular at the far end of Fishery Lane and along the road / path to Edison Rd. as these areas must have habitat more to the bullfinch’s liking ie tall unkempt hedging. Ladywalk does not appear to have the habitat that bullfinches require, our patterns of woodland and habitat management do not appear to be to their liking.

Greenfinch: this species continues to be regular at the Hide A feeders in winter / spring with five at the feeders when I visited on 6 April. Juveniles were regularly sighted here, for example  on 27 July and 12 August and it is interesting to note that 19 juveniles were ringed on the reserve this year.

They nested  on the reserve with one location being a buddlea or adjacent brambles which a male was seen to enter on 25 May. The number of ringed birds suggests that breeding was successful on the reserve – 3-4 pairs?

Linnet:  continue to be a regular on the reserve particularly in the area of river between Rudd Hide and the sluice. On 19 May approx. eight were seen in various locations by the river. They probably nest over the river but there is suitable breeding  habitat on the reserve such as the rape plants by Bittern Hide. Unlike the previous species, no juveniles were ringed, but 10 adults were, which confirms that whilst there were numbers of adults visiting the reserve, many bred elsewhere.

Goldfinch: this species is regular on the reserve with approx. four at T2 on 6 April and there were about eight on thistles by Rudd Hide. It is disappointing that there were no reports of juveniles or family groups on the reserve  but it is hoped that one or two pairs nested.

Reed Bunting:  maximum numbers were higher than in the last two years  with  the highest number recorded being 16 on 30 April and with nos. in double figures on a further three dates. My impression on my visits was that there were more reed buntings calling and sighted and this confirms that. They are particularly active, with birds often chasing each other,  in the reeds under Riverwalk Hide with up to five on 14 May. A juvenile was seen on 17 June between Bittern and B hide and others were at the Hide A feeders by 27 July. It is good to report increased nos. and my estimate would be 4-6 breeding pairs.

Conclusion

It is pleasing to report that 2021 saw a full breeding survey as opposed to 2020 when I was unable to carry out my first visit until 24 May. I am unsure whether the absence of records for the first two months of the 2020 breeding season has had a detrimental effect upon my 2021 records. I believe that the cold April and wet May did have a negative  effect upon breeding and this may be a reason that the ringers were disappointed with the numbers of occupied nestboxes and nestlings within them. As a result of the April / May weather it is possible that second broods did better.

There were some real highlights this year particularly with waders. This is the first year that redshanks have nested for many years and the one bird that fledged had to swim for its life during flooding. The number of Lapwing nests increased fourfold compared with 2020 and  approx.15 birds fledging was an excellent return. As stated in the main report predation was kept to a minimum by the presence of adult birds to see off crows, lesser black backed gulls and a fox, according to photographic evidence.

The undoubted  negative this year is what seems to be a nil return on willow tit breeding. They were present on site during the breeding season, and remain so (winter / spring 2022) and numbers may now be approaching a critical low, from which they cannot recover. The number of calling males and early nesting activity will be awaited with some trepidation as we move into March / April.

Little ringed plover activity could be categorised as a  negative as whilst they hatched the young  were flooded out. We believe that better water management across the reserve particularly at B pool and its scrapes could lead to greater breeding success of this species and waders in general. We hope that this can be implemented through a commercially provided scheme certainly for 2023, and we may be able to make some minor adjustments for this year.

The success of redshank and lapwing highlights the success of earthworks done in this area of the reserve. It is hoped that other work such as on the marsh and in the woodland will have continuing positive effects for birds such as grasshopper and other warblers, as well as lesser spotted woodpeckers. Much of this work is according to a management plan but in my view some of this work is hit or miss and it is difficult to quantify what specific piece of work leads to positive breeding results. The ringing returns provide crucial information about breeding activity: it is unlikely that we would have known about grasshopper warbler breeding success without their input.  This all contributes to the  need for good record keeping through a variety of methods over a lengthy period so that we can measure work done on the reserve  viz a viz breeding success. (as well as numbers of visiting birds outside the breeding season).

Ladywalk Badgers

 A late afternoon in early January, sitting in “B Hide” trying (unsuccessfully on this occasion) to spot a Bittern, I was chatting with Pete Sofley. I was probably rambling on about badgers and otters as I often do, and the outcome of this conversation was that I would set a few trail cameras around Ladywalk NR to see how the reserves badgers were faring. So, the trail cameras were dusted off, checked over and soon attached to any sturdy structure overlooking a likely spot.

 I am a massive fan of the mustelid family, particularly our largest two members, the Otter and the Badger. For me though, the badger is a clear favourite. I’ve tried to capture some footage throughout the year, snippets of which have appeared on Ladywalk’s twitter feed. Quite a few people have voiced their enjoyment of these short clips, and I have been asked many times, “What are the badgers up to now?”

Here is an attempt at briefly explaining 6 months in the life of the Ladywalk badgers.

January

 Badgers do not hibernate, but they do however slow down their activities during winter months. A very mild January led to there being more activity than usual for this month. Our badgers took advantage of the unusually mild weather. They were seen collecting fresh bedding. (Sows may well be pregnant now with the cubs being born around February/March). Sows pregnant now will be as a result of matings that took place last year, probably around September or October. The sows carry out a procedure known as delayed implantation. This means that regardless of when conception occurred, the sow can ensure the birth of the young in the spring when food availability and conditions are more favourable. A January mating was caught on trail camera (a rarity) and lasted for around 45 mins. This is known as “long duration” mating and is a serious attempt at reproduction, rather than short duration mating which is thought to be linked more with bonding when the sow isn’t fully receptive.

February

 This is the month that cubs will be born below ground, often in a special chamber dug out especially for the purpose. If there were successful matings last year there may be Ladywalk cubs below ground now. Only time will tell. Badgers were seen out foraging together this month. A badger was also picked up on the riverside otter camera. This is a good distance from the sett and demonstrates just how far they can range in an evening’s foraging. An average badger sett contains around 5 adults.

March

 If the Ladywalk badgers have had cubs, they will be around 6 weeks old now. They will be exploring the chambers in the sett but won’t yet venture above ground. Lots of badger activity recorded on cameras at various locations around Ladywalk reserve. Badgers are very active at the moment. I’m hoping towards the end of this month or early next month to capture a glimpse of the cubs if there are any on the trail cameras.

April – Coronavirus!

I decided to remove cameras from the reserve to enable me to conform to the government’s guidelines of no unnecessary travel. I did not want to be travelling to the reserve to maintain the cameras. Still no evidence of cubs.

Late April / Early May

 The government have clarified the position on travel to exercise. You can take a short drive to exercise. I took this opportunity to replace one trail camera. Still hoping for evidence of cubs. I left this camera for just over a week before deciding to visit again to replace card and batteries. The camera although quite securely fastened into position had been moved out of position. The badgers do sometimes interfere with the cameras if they can reach them. It’s that innate curiosity that the weasel family are famous for, they just can’t help themselves. The result was the camera recording a weeks’ worth of tree branches blowing in the wind. Still no evidence of cubs!

 May

 If there are cubs, they will be between somewhere in the region of 11-13 weeks old now. They should be out foraging with the sow and enjoying lots of chasing about and play fighting.

Proof of Cubs

 Late May and the badger cubs were seen around the reserve enjoying the warmth of the sun. I initially saw a single cub that disappeared into dense undergrowth, eventually reappearing with two siblings. It was a fantastic sight watching three cubs setting out foraging in the early evening. The Sow wasn’t far behind keeping an eye on them.

 A successful year for the Ladywalk badgers. It is late July as I write this and the cubs will now be exploring their habitat, fully weaned and feeding themselves. I have caught one on trail camera a few times heading to a favoured area to take a drink.

 It’s a difficult time of year for setting trail cameras at the moment. Various vegetation is at its peak and very dense in certain areas. This makes setting cameras tricky as the plants and foliage moving in the breeze repeatedly set the cameras off. I’ll be putting the cameras out again in the autumn to see how the badgers are faring.

Moocher

 

Shoreline Improvements

  After last year missing out on getting the main marsh mown and baled for hay due to weather conditions, we made sure we got an early cut and collect in this year. We had a good display of wildflowers and orchids this year but nothing compared to the previous year in variety and amount. Since we started hay making on main marsh seven years ago the marsh has improved year on year and in recent years has been more successful for breeding Lapwing.

  The local farmer has mown the main areas that they can reach with their heavy machinery. The wetter strips around the main shoreline and scrapes were left, so we started this week clearing in preparation for returning waders and wildfowl. The shorter sward areas were mown to improve for grazing wildfowl, particularly Wigeon.

 We have purchased a cheap, second hand rotavator for the immediate shoreline. The idea is that we will refresh the soil for invertebrates which will benefit waders now and again in the spring when the shoreline is exposed again.

  John Allton has been working on a new ‘scuffle’ for the tractor which in essence works as a plough for sowing the wild bird crops but we can also use it to ‘scuffle’ the soil along the rest of the shoreline. It’s a great bit of kit and will use on other areas of reserve.

  As I was mowing this strip that was left by the main contractors it was teeming with life; Short-tailed Voles and loads of insect life feeding on the late nectar, particularly the Water Mint. Daddy long-legs, Crickets, Bees and loads of moths were disturbed, especially Silver Y’s.

  We decided to leave strips of the best areas for wildlife and these will also be good for feeding areas for Snipe who have a fondness for feeding in areas of Purple Loosestrife. I noticed Red Bartsia growing this year for the first time which is semi-parasitic and  is another good addition to the marsh.

  To add to this we have been working on how to improve the main shoreline of the marsh along the western edge of the main pool. We have been looking at slowing down the encroachment of Phragmites which are slowly taking up more of the shoreline. So we will start cutting back some of the areas which will open up the pool for winter wildfowl and Snipe which seem to prefer feeding in the winter stubble edges. Also with increased predator activity a more open shoreline will give feeding birds more reaction time to predators making them less nervy.

Hopefully all these additions will help improve feeding conditions for both waders and waterfowl over the coming months.

LADYWALK  RESERVE – BREEDING REPORT 2019

Introduction

Thirteen visits were made, across the whole reserve in the period between 11 April and 8 August.  With the exception of a visit on 13 June when there was no access to the reserve due to flooding each visit took approx. 5-6 hours in duration. As was the case in the three years that I have done this surveying I split the reserve into 12 transects and my methodology was again to list all birds in each transect by sound or sight on each visit. The reporting details that follow are largely from my notes, plus information from other sources such as Pete Sofley (reserve warden),  regular users of the reserve and on  Twitter. This year we have been provided with much information from our ringers, notably about the  success or otherwise of tits in the nestboxes. I am sure that there are other peoples’ breeding records that can enhance this report. If so please forward them to me via Richardking54@gmail.com.

 

The transects remain the same as previous years and are as follows –

Transect 1 – from car park to the double gates, technically not part of the reserve but treated as the reserve in this report.

Transect 2 – from double gates to Hide A.

Transect 3 – at Hide A

Transect 4 – from Hide A to Rudd Hide *

Transect 5 – at Rudd Hide

Transect 6 – from Rudd Hide to Riverwalk Hide*

Transect 7 – at Riverwalk Hide

Transect 8 – from Riverwalk Hide to Bittern Hide*

Transect 9 – at Bittern hide

Transect 10 – from Bittern Hide to B Hide*

Transect 11 – at B Hide

Transect 12 – from B Hide to Lock Up inc. the wood & fishing pools*

*Or vice versa

Visits were normally between approx. 8am and early afternoon and were dated –

11 April                                                           6  June

20 April                                                           17 June

26 April                                                           1 July

6 May                                                              18 July

17 May                                                            29 July

31 May                                                            8 August

 

Weather

  2019 saw some of the worst flooding the reserve has seen, with a greater frequency than during recent summers. The breeding season started well weatherwise as April and May were drier than average with quite a lot of dry and sunny weather. The deterioration came in June, particularly between 11th and 14th when there was nearly two inches of rain, leading to flooding at the reserve entrance putting it out of bounds. The sand martins were washed out of their nests, and subsequently in two more floods in the next two months. It is impossible to aggregate the effects of this flooding on breeding birds but it is likely to have wrecked the nests of various warblers and ducks. For example shoveler were present through the breeding season, and have nested here in 2017, but there was no evidence of successful breeding.  In the case of lapwings if it was not the nests being washed out it was the chicks drowning or being predated , in the June floods at least two chicks were lost. June and July both had more than twice the average rainfall and August was not a lot drier with the 8th being particularly wet. With three floods through the summer it seems likely that some birds such as sand martins whose nests it is easy to monitor attempted further nesting, twice, but were flooded out and eventually gave up.

A  detailed summary for the 2019 breeding season

Mute Swan: There were two breeding pairs on the reserve, the same as 2018. A nest below Riverwalk Hide was first seen on my visits on 11 April with another nest seen at New Bay on 20 April. By 17 May two cygnets emerged from the nest below Riverwalk Hide and the New Bay nest produced seven cygnets. Bizarrely two of these cygnets disappeared during the June flood – were they washed away or predated? No more cygnets have disappeared since.

It is possible that another pair nested on the river because a pair plus nine small cygnets were seen on the river on 17 May. It is not clear where they nested although on 11 April there appeared to be a nest on the river island but this was not seen again.

MuteSwanCygnets2

Canada Goose: More broods were recorded of this species than last year when there were three. On 20 April three nests were within sight of Hide A and a bird on a nest in front of B Hide. The first goslings were seen on 6 May and the peak date for families was 31 May when three goslings were on the marsh, seven on the new scrape and elsewhere there were families of four, two (twice) and eight. By the end of July many of these goslings were on the river.

Shelduck: None were seen on the reserve during my recording period, unlike previous years when at least their presence in April and May provided some optimism that they might breed.

Gadwall: are present throughout the year on the pools and river with five pairs recorded on Main Pool on 6 May. Broods were reported on 17 May, 10 June (1+9)  and 21 June when there were six ducklings at B Pool  I saw a single duckling on B Pool on 1 July where an adult and five ducklings were later seen, prob. those recorded last month. On 20 July a brood of nine was recorded on Twitter.  On 8 August there were about 20 gadwall on Main pool but the only brood was of four ducklings, with another brood of eight on B Pool.

Teal: Pairs were recorded on the Main Pool on 20 April and 26 April (two) and whilst small numbers were present through the summer there was no sign of breeding.

Mallard: Broods were numerous and families seem to gravitate to the river where there seems to be little predation. The first brood I saw was a female  + 7 at the Angling Pools on 20 April.  A female + 9 were on the river on 26 April and there was another brood of ten seen on 6 and 17 May. Other broods were as listed –

6 May – two broods of 4 and 9 on river between Rudd and Bittern Hides and two broods (1,7) on 31 May

31 May – 1+3 large ducklings on the Main Pool

6 June – 1+3 large ducklings on the river and about six juveniles nearby

17 June – 1+6 ducklings in same location and a female with 11 ducklings elsewhere on the river.

1 July – 1+4 at the above location, and a female was seen with 1 duckling on B Pool. There were also a number of older juveniles on the river on this day.

18 July – 1+5 large ducklings on Main pool. On this date a light coloured female was on the river with 7 ducklings. This is the third year that I have seen her with ducklings and they were seen again twice in the next fortnight. On this date 1+9 were reported on B Pool.

The Angling Pools yielded a number of families as in addition to the reserve’s earliest brood 1+6 were seen on 6 May and these were seen again on 17 May. Two broods were here on 31 May (one with 7 ducklings). On 6 June this brood was seen again, near to 1+6 small ducklings. Older ducklings were often seen and heard on these waters as the summer progressed. The small size of the pools with their fallen trees and amount of vegetation surrounding the pools make this area a secure location for breeding mallard.

Shoveler: It is two years since the successful breeding on B Pools and it is possible that breeding failed due to the flooding in 2019. There were pairs present through the breeding season such as at New Bay on 20 April, Main Pool on 17 May. B Pool and the new scrapes would probably have been the best site for breeding and pairs were seen here on 6 June and two were in the same area on 1 July.

Tufted Duck:  Pairs were regular on the pools and river throughout the spring and summer but there was little evidence of breeding, other than an adult + three photographed at B Pool  on 13 August. This species had disappeared from the reserve by late August and why do so few breed here? Secluded areas such as the Angling Pools would seem ideal for breeding and it is a mystery why Marsh Lane has 100 ducklings, Ladywalk so few.  It is possible that flooding may have been a factor in this failed breeding attempt.

Goosander: this species is seen regularly on the river particularly, and the first report of successful breeding was a report of an adult +2 on 2 May. On 17 May I saw a female at a nestbox between B Hide and the sluice, one of two nestboxes in use by this species.

On 6 June there were reports of five broods, totaling 33 ducklings,  between Water Orton and the reserve, with 10 young having been seen the previous day,  so the evidence is that goosanders are increasing.

PHOTO-2020-05-10-15-37-46

Common Pheasant: As usual these were present throughout the summer and  they are likely to have successfully bred although no broods were seen. A broken egg was found at T8 on 6 May; this may have been evidence of a chick hatching or of predation.  It is likely that there were juveniles about the reserve later in the summer.

Cormorant: nested in the same location as in recent years and during my visits I counted between 19 and 28 nests. I suspect there were about 24 nests, and by 17 May many held nestlings that eventually found their way to the main pool.

Little Egret: the maximum recorded on the reserve during this survey was nine but there was no sign of them breeding here, and they did not associate with the breeding cormorants.

Grey Heron: as the summer progressed  juveniles were seen on the reserve from one or two local heronries as was the case in previous years.

Little Grebe: birds were present throughout the year. There was no evidence of breeding at Rudd Pool but 1-2  pairs were regular on Main Pool with 1+ 4 there on 29 July. Whether this brood was predated or not, or it was another brood on 8 August there was only one adult, one youngster present. On this date at this location there was an adult with something in its beak which may have suggested two broods present on this day.

On B Pool again there were one or two pairs and the first youngster was photographed with its parent on 30 April. On 4 June an adult plus two were reported here and on 17 June an adult + a small young bird was seen in front of the hide, whilst on 18 July two juveniles were reported.  Elsewhere on B Pool 1+3 were seen from Bittern Hide on 5 August.

Again for this species the secluded Angling pools would be a good place to breed and in June and July adults were seen or heard here. I suspect they did breed here and a possible brood was seen on 29 July.

It is likely that there were about four breeding pairs on the reserve but it is impossible to know how many young birds were predated but some birds will have fledged.

Great Crested Grebe: birds were present throughout the survey and on 6 May there were two pairs on the reserve. There was a pair nest building, viewable from Bittern Hide, on 6 May and by 17 May there was a nest in front of the hide but the nest soon disappeared.

 One was on a nest at Main Pool on 31 May and 6 June but this nest had disappeared by 17 June after the first period of flooding.

On B Pool in front of B Hide a pair were on a nest on 31 May and 6 June and then relocated by 17-6, probably due to the flooding. Unlike last year I have no records of youngsters.

Sparrowhawk:  bred on the reserve for the second consecutive year, by the Angling Pools, but it is not certain that they were successful. From my regular walk birds were heard at the nest on 20 April and then disturbed twice in May. On 15 and 17 June there were calls that suggested young at the nest, however there was no evidence of young birds in flight, unlike last year when they were really prominent.

Buzzard: one was disturbed from a tree on TI and more regularly heard off the reserve than seen on but again no evidence of breeding which considering the size of the reserve and its trees is disappointing. .

Water Rail: winter numbers in late 2019 suggest this was a good breeding year with the reedbeds in front of B Hide the site of most sightings. On 3 June 1+5 were seen and photographed here and on 25 July young were heard and photographed. Again in the same location 1+3 were photographed on 5 August, and on 16 August there was a report of an adult and chick again in the same location. It is likely that at least two pairs bred, possibly three.

Water Rail3

Moorhen: Keyhole Scrape remains a favoured location for this species with 2+3 there on 20 April and a second brood of two very young birds on 26 April, which were seen again 10 days later. These young were seen under the feeders on occasions and there was an adult and another young bird by Keyhole Scrape on 29 July and a fortnight later.

Rudd Pool held 1+4 small ones on 6 June, the date that there was an agitated bird by the Angling Pools which suggested that young may have been present. In fact only one young bird was seen here (1 July) but it is likely that there were other broods here.

This species may not do as well on the reserve’s larger waters. At Main Pool two juveniles were seen independently of each other on 18 July and on 8 August there were four fledged juveniles on the pool and another two on the river.

On B Pool from Bittern Hide single juveniles were sighted on 17 June and 8 August in two locations.

It is likely that some young birds were predated but 2019 seems to have been a good year for this species.

Coot: the first recorded nesting activity was a bird nestbuilding on Main Pool on 20 April. Other nesting activity on Main Pool was on 6 May when there was a young bird present and a nest on a pallet raft on 31 May. Two occupied nests were seen on small islands on this pool from Riverwalk Hide on 31 May and were still in situ the following week when there was also an older juvenile present. On 1 July there was still one occupied nest and an adult and large juvenile on the water.

New Bay off Main Pool was the site for a nest on 18 July, and still in use 25 July.

Rudd Pool accommodated juveniles (3) on 31 May and one on 6 June. also, with this again being seen on 17 June. Coots did well here with  two broods of two and seven on 1 July with the former brood seen on 18 July. A large immature was seen on 29 July which suggests a success rate for coot breeding here.

Details from B Pool as follows –

17 May – two broods  (1+2, 2+2 and a nest present on the new scrape.

31 May – nest in front of Bittern Hide, may have been an old great crested grebe’s nest

6 June – again from Bittern Hide 2+1 small one which were also seen on 17 June, as well as 1+2 larger ones

1 July – a coot with young on its nest in front of the hide and by 13 July “several” young coots was recorded.

Details from B Hide also overlooking B Pool were as follows –

6 May – two broods (1+2 small ones; 2+ 1 medium sized bird) and a nest elsewhere.

31 May – family in front of the hide, two broods (2+1, 2+2) and two young birds nearby.

6 June – 1+2

17 June – an unspecified number of juveniles seen.

1 July – an adult with a large juvenile and an occupied nest.

Unlike last year there appeared to be more successful breeding at the Angling Pools –

6 May – one young large coot

17 May – a brood of at least two seen and heard, and they were also present on 31 May again heard, unless it was another brood, on 6 June.

15 June – young birds were again heard.

1 July – two large juveniles present.

18 July – two noisy juveniles seen and on

29 July –  a fully fledged bird was seen.

With these records of fledged birds as well as the number of nests it would appear that the species has done well in 2019. But predators such as crows and lesser black backed gulls are never far away. On 20 April a young bird was taken by a LBB Gull from with the reeds in front of B Hide. Done very quickly and dramatically.

Oystercatcher: in April there was a pair present on the reserve, particularly at Main Pool and they nested on an island here. Two young birds were hatched on 5 May, and I saw one of the young birds with an adult. Unfortunately by 17 May whilst the adults were present there were no young birds.

There were three adults at Main Pool on 17 June but no evidence that there was a further attempt at breeding.

Little Ringed Plover: did not breed here, although quite regular on the new scrape in spring. Up to seven adults were in the area of the new scrape in April and would prob. have been passing through, as were two in the same location on 13 July.

Lapwing:  a good presence of this species in April including four displaying and by the end of the month five nests were being reported, mainly on B Pool islands to which it appears that foxes could not gain access. The first brood was here on the reserve with four newly hatched on 30 May and on 6 June there were five adults present, when black headed gulls were being mobbed.  I saw one chick by Main Pool but at this stage there were five on the reserve. On 6 June I saw 3 adults and two chicks at B Pool but the floods in mid June accounted for two chicks at B Pool but there were still four present on the reserve on 14 & 17 June and later that month. Additionally it appears that a nest on the shingle bank beside B Pool, to the right from B Hide, was flooded.

Into July there were a number of adults on the reserve, such as nine on 1 July. There were two  juveniles at B Pool four at Main Pool on 3 July, reported PS . On 18 and 27 July I saw a fledged juvenile at B Pool so we know that at least one bird from the reserve made it to this stage.

Lapwing5

Common Tern: After 2018 when a pair raised two young on the newly installed tern raft, there was no breeding despite there being two rafts on site. There were two adults present on 20 April and a pair was reported mating on 28 May but birds were few and far apart with no interest whatsoever in the tern rafts.

Black-headed Gull:   Birds were present, including juveniles from elsewhere. Their presence in the breeding season and our habitat suggests that breeding is likely in the future.

Feral Pigeon: are also regular on the reserve but no information as to whether they breed on the reserve. Probably nest locally on man made structures such as Whitacre waterworks and bridges.

Stock Dove:  These remain regular across the reserve especially in the line of poplars by the fishing pools. They undoubtedly nest on the reserve, including in the owl nestboxes. The ringers reported two broods of two in two nestboxes.

Wood Pigeon:  As usual there were constantly on the reserve, where it is sure to have bred in several locations. A bird was seen on a nest just beyond the gate from the car park on 17 June.

Cuckoo:   was present on the reserve during May and June and I encountered two behind Bittern Hide on 6 May. A good record on Twitter was female birds in the reedbed on 17 May.

Barn Owl:  Successful in a nestbox on the reserve with two chicks reported on 22 May which were subsequently ringed on 5 June.

Tawny Owl: Last year two pairs bred on or near the reserve.  There was a bird on three eggs in a nestbox reported by the ringers on 18 April but this nesting attempt was not successful. There was only one other report of birds in the breeding season, two youngsters calling in the Angling Pools area (T12) on 14 August.

Kingfisher:  Regularly seen or heard along the river. On 6 May one seen to catch a fish on the river behind Bittern Hide, and again seen there on 13 May. On this date, also, two or three by the copse where the two rivers merge.

 Additionally on 17 June one was seen fishing successfully at Rudd Pool and seeing / hearing birds three times in a visit is not unusual.  It is impossible to say how many actual birds are encountered per day but clearly they bred, prob. near the old bridge where the rivers merge and on the river behind Bittern Hide. I suspect that they may have also bred upstream from the car park. These breeding pairs would have been affected by the floods so it is unclear about the success levels of the breeding.

Green Woodpecker: not as regular on the reserve as in previous years and the birds seen or heard were scattered across the reserve. One pair at least bred on the reserve, a nest was reported by the ringers near the ringing station.

Great Spotted Woodpecker: The most common woodpecker on the reserve and encountered in all areas. Nested in a dead willow on Transect 1, halfway along the entrance track on the left. Young were heard in this nest on 31 May and 6 June.  On these two dates several adults and young birds were also seen between Rudd and Riverwalk Hides, where a pair bred, and the area of the copse would have been a successful breeding site.

This species is also regular on the Hide A feeders with a juvenile and male there on 17 June.

It is likely that there were 3-6 pairs across the reserve in 2019.

Lesser Spotted Woodpecker: This species was present on the reserve in late winter and whilst not reported during the breeding season is likely to have nested on or near to the reserve.

Kestrel:  This species was seen less regularly on the reserve this year, in fact it was seen most regularly the other side of the river at T5. No evidence of breeding on or near to the reserve in 2019.

Hobby: Birds, normally juveniles, were present on the reserve, notably  between August and early October, attracted by dragonflies.  My only sighting during my survey visits was one over the reserve on 17 May. They did not breed on the reserve but probably bred locally

Peregrine Falcon: Similar information this year as last with a juvenile often on the pylon in the car park area as well as making forays into the reserve. This bird came from a nest on the Sainsbury’s warehouse which yielded one young bird. On 8 July two juveniles were reported on the reserve via the blog.

Magpie: Regular across the reserve although a fewer number of family groups recorded this year. On 13 June there was a young bird with adults on T1 and probable young were heard at T8 on 1 July. It is likely that at least two pairs bred on the reserve.

Jay: These are regular across the reserve and most were encountered on 1 July when a small group near the entrance gate suggested a family, and another group was heard elsewhere. However there were fewer juveniles seen this year than in previous years. It is possible that at least two pairs bred.

Jackdaw: Birds were regularly seen on the marsh as in previous years and often seen flying from the trees behind the cormorant colony. They probably bred here but there seemed less birds visible than in 2018.

Carrion Crow: Regular across the reserve and several nests seen in large trees eg the black poplar on the opposite riverbank between Bittern and B Hides. On 31 May a family group of four were between Riverwalk and Bittern Hides where they agitated a willow tit family.

On 1 July an adult was feeding an egg to a juvenile at T11.

I would suggest 4-6 breeding pairs across the reserve.

Raven: On 17 May family party (2+3) feeding on a dead sheep over the river. Birds not often seen on the reserve during my survey visits but would have nested near the reserve, possibly in the area of wet pasture that is proposed as an addition to the reserve. 

Goldcrest:  This bird was seen and heard across the reserve very often, prob. more than 2018. Particularly regular on Transect 1 especially by the reserve gate. Probably nested in the yews by the copse, as usual and on 8 August a juvenile seen between Riverwalk and Bittern Hides. Birds were widespread across the reserve with another brood reported on 3 June and there may have been 3-4 breeding pairs.

Blue Tit: Unlike last year when no ringing was done some ringing took place for this species, and the next, in nestboxes: see the ringers’ returns below. Additional records include five families being located out of their nests on 31May. On this date and on 6 June there was a family still in a nestbox on T12 where a lot of families were encountered on 17 June and 18 July.

Blue Tit, 2019 –

Number ringed            109

Number of nests          16

Average                       6.8 nestlings per box

Great Tit: See the nestbox records for this species as well as that of blue tits. More great tits were ringed in 2019 than blue tits and family groups were recorded regularly after 17 June inc. juveniles at the A Hide feeders

Great Tit, 2019 –

Number ringed            130

Number of nests          22

Average                      5.9 nestlings per box

Coal Tit: This species appears to have declined in the last two breeding seasons, and again they were most often recorded in the area of the woodyard (T2) or in the adjacent T12 (angling pools). Breeding was proven when an adult and four young were seen on 3 June this suggests that at least one pair bred successfully.

Willow Tit: Much work has been done to encourage this declining bird and it appears to have paid off with estimates of up to four breeding pairs producing approx. eight young. In early spring a bird was seen constructing a nest in the damp woodland off  T12 and on 17 May PS reported a bird with a faecal sac in this area.

On 31 May alarm calls of this species were heard and a family seen behind Riverwalk Hide, due to the presence of a crow family.  PS had seen three juveniles a day earlier. Birds were also heard in T12 on two visits in April  and a family were reported between Hide A and Rudd on 6 June.]

Willow Tit8

Marsh Tit:  The blog reported 2+2 on the reserve on 4 June on the west side of the reserve and  PS reported juveniles of this species on 8 July although the location was not specified. It is likely that two pairs bred, with one pair in the area of Transect 12 (angling pools).

Sand Martin:  Birds were present throughout April and May and nested in two riverside locations, behind Rudd Hide and between Riverwalk and Bittern Hides.

First recorded at nest holes on 20 April and on 26th birds were collecting mud from the bird crop area behind Rudd Hide. On 31 May I counted approx. 15 nests in the riverbank behind Rudd Hide and this no. had increased to about 20 on 6 June. By 17 June the birds had been flooded out but were back at their nest holes. By 1 July they had been flooded again and on 18 July some nests were being used behind Rudd Hide despite further flooding. On 29 July approx. 12 birds were entering nest holes in the same area, only to be flooded again. By my visit on 8 August the birds had deserted.

The smaller colony in the riverbank between Riverwalk and Bittern Hides was less easy to observe. In early May there were approx. 12 birds here and on 31 May birds were collecting mud for their nests from the vicinity of Bittern Hide but again these were flooded out by the succession of summer floods.

The conclusion was a totally unsuccessful breeding season for sand martins due to the flooding and this has led to a successful application for funding for a sand martin bank which will hopefully be in place near to Rudd Hide for the 2020 breeding season.

Swallow:   Assumed breeder in the stables and associated buildings across the river. Birds from here were collecting mud by Bittern Hide on 26 April.

House Martin:  Small nos. of this species over but did not breed at the reserve. Birds were collecting mud near to Bittern Hide on 31 May possibly by the birds that nest at Lea Marston.

Cetti’s Warbler:  There has been interesting information from the ringers this year as they ringed 24 birds and recaptured a bird on 21 August which was clearly sitting on a nest for its second brood.  This does not mean that there is this number of birds on the reserve but there is an increased number of birds, at one stage there was an estimate of nine pairs. 12 young were ringed this year which suggests an excellent year.

The species was heard in reedbeds  across the whole reserve and the reedbed in front of B Hide is again the  regular location for this bird and it would have bred here. The species was recorded here on six of my visits in April and May including a sighting on 31 May.

Other areas where it was recorded were between Hide A and Rudd Pool, in the vicinity of Main Pool, near Bittern Hide and between Bittern & B Hides. Two juveniles reported on the blog on 8 July.

Cetti

Cetti’s Warbler

Long-tailed Tit:  Several groups of this species seen on each visit including a party with  juveniles at T1 on 8 August. Undoubtedly bred on the reserve as evidenced by family groups and the ringers’ records of ringing 28 young..  Numbers appear to be stable –between five and seven breeding pairs?

Chiffchaff:   The highest number encountered during my visits was nine on three dates in July and August but there may have been passing birds by then (see later chart). There was evidence of breeding ie a family at T1 with at least three young birds on 6 June; a probable family on T4 and two likely juveniles at Hide A on 8 August. The ringers ringed 27 young birds. A third of these were ringed before 31 July which suggested that these were bred on the reserve. There was an agitated bird in the copse on 31 May and this suggested the presence of a family.

As is the case every year there seemed be a lot of contact calls from this species across the reserve in July / August.

Willow Warbler : This species was only recorded on three dates in April and on 18 July. It was not recorded between 6 May and 1 July although ten young were ringed between  18 June and 14 September. It is likely that this decline is due to global warming but over the years our trees and bushes have grown much taller. The area where they are most often encountered is the hellebore area where bushes have been cut back and the grass is shorter.

Blackcap:  Again this was the most numerous summer visitor with 24 birds, inc. two pairs, seen or heard on 20 April. It is prevalent on Transect 1 where birds were reported mating on 20 April, a juvenile seen on 13 June and a likely family on 29 July. Other evidence of breeding was a possible juvenile at T8 on 17 June, a family between Bittern and B Hides and on 19 July two juveniles were associated with tits feeding on ripe bleckberries at T12. Six juveniles were ringed on19 June.

15-20 pairs across the reserve again this year?

Garden Warbler: This species was recorded in similar numbers to those of 2018. Between one and three were recorded on most dates but on 26 April there were 14 birds, seemingly passing through. Evidence of breeding was that nine young were ringed, all but two by 31 July and a probable young bird was by the entrance path (T1) on 29 July. I would suggest that there were only about three breeding pairs across the reserve.

Lesser Whitethroat:  I only had one record this year, one heard on the marsh on 20 April. Two or three were recorded by a visitor two days later but it seems that they did again not breed on or near to the reserve.

Common Whitethroat: Numbers were higher this year than last with most on 31 May when I recorded eight birds + a pair, with five or six regularly encountered. The most common locations were the more open areas by the river – T4 in the vicinity of Rudd Hide and T6 along the nest stretch to Riverwalk Hide.  The former is invariably their best location with regular sightings, inc. two young birds in the brambles on 6 June and probable juveniles heard in the bird crop on 8 August. This species would have nested in the bank of brambles. On T6 on 18 July one family, possibly two were seen. The ringers state they ringed fourteen.

It is likely that there were at least three breeding pairs on the reserve, and quite likely more.

Grasshopper Warbler: PS reported that a pair bred on the reserve producing two broods and up to two birds were in song in April. I did not encounter any birds this year at Ladywalk.

Sedge Warbler: Highest count of birds seen / heard across the transects was ten on 17 May (eight in 2017, five 2018) and there were consistently less sedge warblers than reed.  Both these species and Cetti’s were most regular in the reeds in front of B Hide.  Evidence of breeding were 1-2 juveniles seen between Riverwalk and Bittern Hides. The ringers  have documented  that 33 young were ringed this year. It is unclear how the reed nesting species were affected by the floods and on the basis of my figures there may have been about four breeding pairs.

Reed Warbler: This species was consistently more common across the reserve than sedge warbler with between five and nine birds recorded on every visit barring the first and last visits.  The nine birds  recorded on 29 July and  may have included migrants, tying in with ringing records as on 21 August 26 new birds of this species were ringed  This suggested that these were new birds on the reserve, the reserve’s breeders having left.

In terms of breeding activity, the ringers state that they ringed 82 young birds between mid June and September. An adult was reported carrying food near the ringing area on 14 June and two fledged birds were at B hide on 14 June, this being after the flood.

This species regularly seen at Keyhole scrape where a pair were seen in courtship behavour.  As a result of the floods?  As with Cetti’s and Sedge Warblers very regular in front of B Hide, where one was seen with food on 18 July and five birds were recorded on my next visit, 29 July.

Nuthatch:  This bird seems to be declining in the breeding season at Ladywalk, and was more likely to be heard over the river.

One was seen on a dead tree between Riverwalk and Rudd Hides on 6 May, another was by the entrance track (T1) on 1 July and one was heard between  Hide A & Rudd on 8 August.

On 14 August a family was reported at the Hide A feeders. It is likely that one or two pairs bred.

Treecreeper:   There has been a greater presence of this species than the above with regular sightings of, or hearing birds on the walk from the car park to Hide A. They were also regular at the copse (T6) and recorded from all the wooded areas of the reserve. By 17 May birds had fledged from a nest in a willow in the area of the screen, where they were encountered throughout the summer. On 6 May a bird was heard in the wooded area surrounding the angling pools, where they were subsequently recorded on five occasions including two juveniles seen on 18 July. .

A juvenile was ringed on 22 May and I estimate 4-6 breeding pairs on the reserve.

Wren:  Again the most numerous woodland breeder on the reserve, with the most being heard or seen being 30 on 31 May, similar to last year. There were many examples of successful breeding –

Transect 1 – Fledgling on 17 May and a family with approx. four fledglings on 29 July.

T2 – Juvenile on 8 August

T6 – family with young on same date as above

T9 – family seen on 17 June, and a family of three young on 29 July

T12 – a likely family here on 17 May and two young seen a fortnight later.

On the basis of the above and my sightings chart there is an estimate of twenty breeding pairs.

Starling:  I did not record this species during my visits but I assume that they again bred at the old stables over the river.

Blackbird:  Widespread across the reserve partic. in the wooded areas. The most birds seen or heard was 30 birds on 6 May, a much higher figure than in 2018. My estimate is that a probable 15 pairs bred. My only specific example of breeding was a female with food at T8 on 17 June.

Song Thrush:  Recorded across most of the transects as evidenced by the no. of singing birds. Three were heard in song at the same time on18 July and numbers on the reserve appear stable or are rising. I would estimate five breeding pairs.

Robin:  Maximum  birds seen / heard was 21 on 20 April which is the same number on a similar date in 2018. On other visits recorded nos. were between 4 and 13. Juveniles were encountered regularly across the reserve and “lots” were reported on 26 May and on 31 May one was seen at T8. Other juveniles were seen such as at T2 on 6 June, and one on the path at T8 on 18 July. This is a common breeding bird on the reserve with prob. an excess of 12 pairs.

Dunnock:  The most recorded  was 10 birds inc. a pair on 6 May and nos. averaged about 6 during the breeding season. I estimate at least nine pairs across the reserve on the basis of sightings and song. Clear evidence of breeding success was a juvenile at T12 on 18 July and a likely family at T10 on 29 July.

Grey Wagtail: Regularly seen by the river between Rudd & Riverwalk Hides and prob. successfully nested at the confluence of the rivers here.  A juvenile was seen here on 17 June and a male with a juvenile also in this vicinity on 29 July. A pair plus two juveniles were reported near to the car park on 13 May so this suggests at least two pairs nesting on the reserve (or officially just off it),  One pair may have been double brooded.

Pied Wagtail: Evidence of breeding was a juvenile reported by PL on 28 May and one  below Riverwalk Hide on 6 June, with an adult nearby. On 13 July there was an adult with a juvenile near to Bittern Hide where an adult bird was seen in both April and May. Finally there was a pair at B Hide on 17 May.

There is an estimate of 2-3 breeding pairs.

Chaffinch: Whilst birds are quite common at the Hide A feeders this species is not common on the reserve in the breeding season. The maximum was four on 6 May but on five visits none were recorded. Nevertheless at least one pair bred as young birds were reported in good nesting habitat on 1 July near to Rudd Hide.

Bullfinch:  There appears to be a decline in this species at Ladywalk  first noted in 2018. They were less regular at the feeders and only heard or seen elsewhere on the reserve on about five occasions so it is possible they did not breed on the reserve.

Greenfinch: This species has increased again at the reserve particularly at the Hide A feeders during the winter. These feeders were attracting fledged birds by mid July and on 18 July the visiting chair of WMBC reported ten of this species inc. juvs. across the reserve.

Good nesting habitat was the gorse by the entrance track (T1) where a pair were seen on 6 June and another ideal site for this species was the bramble bank by Rudd Hide. They prob. nested here or the other side of the river from this area.

It is likely that 3-4 pairs bred on or near to the reserve.

Linnet: This species continues to increase and is more widespread on the reserve. Several years ago they were confined to the area between the copse on T5 to T7, and over the river, and the max. no. here was at least five on 20 April and they would have bred in this area as usual. Additionally  they prob. nested beside the entrance track to the reserve (T1) where on 31 May a bird’s agitated behavour may have suggested a nearby nest. Further evidence of this species spreading further was two on the gravel beside B Pool.

It is likely that 2-3 pairs bred on the reserve or just over the river.

Goldfinch:  This species was encountered on most occasions beside the river, particularly the area between Rudd and Riverwalk Hides. On 29 July a family group with at least one juvenile was seen further along the river between Bittern & B Hides.  These areas had suitable nesting sites for this species so it is likely that one or two pairs bred on the reserve.

Reed Bunting:  Recorded lower numbers this year than last during my visits, with a maximum of four recorded on several visits (max. eight in 2018). Regularly heard calling from the marsh by Riverwalk Hide and sure to have nested in that area. This was reinforced by the report of 29 young being ringed through the summer. Also on 31 May there was  a female exhibiting distraction behaviour, and young birds seen nearby, between Riverwalk and Bittern Hides. At least one juvenile was ringed.

Approx. four breeding pairs?

Conclusion

2019’s breeding season was dominated by the regular flooding and the likely impact that this had on breeding success. It has been easy to document the effect on Sand Martins and we can speculate that ducks such as Shoveler and Tufted were affected and quite possibly some warblers were affected by what were very high water levels through the reeds.

There were some successes, goosanders are increasing in this area of the Tame and are using nestboxes, and lapwings produced chicks although only one fledged. That was better than  recent years and may be due to some of the work done to deter foxes.

It is fantastic to report the efforts of our ringers who put in many sessions at the nestboxes, the marsh and around the feeders. There were some interesting findings particularly surrounding Cetti’s Warblers and the number of juvenile Reed and Sedge warblers ringed. The information from them and the consistent reports from my four years of this breeding survey are assisting us to develop a greater picture of bird numbers and trends in the breeding season which can assist our habitat management in the future. My methodology is very different to that of most breeding bird surveys, and is time consuming. It is possible that even despite this some of my estimations of numbers of breeding pairs are on the low side.

Any comments about this report or additions to last year’s records would still be appreciated. I write this as the 2020 breeding season commences with no ability to carry out this or other surveys, inc. ringing, at present. I am sure we will get into action in later months when it will be interesting to note whether a reduction of reserve visitors and habitat work has an effect on this year’s breeding success.

June Mothing

 The highlight really was a pristine Blotched Emerald trapped by Hide A. The first we’ve caught on the reserve and I’m struggling to find any other records. A species of mature woodland, feeding on oaks and there’s not many of them at Ladywalk. Burnished Brass and Blood-veins looked particularly fresh and sharp.

 As for the morning’s birds, the sorry looking drake Mandarin was waddling around at B pools and a drake Garganey (looking a bit tired too) was briefly on Main Pool viewed from Hide A though it didn’t hang around.

September WeBS

  Duck numbers lower than of late, particularly Gadwall. Moorhens seem to have had a good breeding season. The scrapes at B pools continue to disappoint a little this autumn, 2 Ringed Plover flew north over Main Pool mid-morning calling, they swirled and nearly dropped on to the scrapes but changed their minds and kept going. The search for a Ruff continues too this year despite there being plenty elsewhere. I was in duck mode and time poor, so passerines didn’t get much time but there was a bit of Mipit passage and quite a few Pied Wags over, whilst a Willow Tit called from the New Bay area for the first time in a while after a quiet late-summer spell.

West Midlands All-Dayer Autumn 2019

A very enjoyable day. Though low on waterbird variety, passerine activity was high. Chiffchaffs and crests filled the trees and hedgerows, there was always plenty to sort through. A brief bit of overhead passage early on saw 3+ Tree Pipits, 2 Yellow Wags, Swift and good numbers of hirundines. Little Owls called from behind Bittern Hide and north of the car park. A Lesser Spotted Woopecker showed in willows along the river whilst another drummed softly as we ate breakfast in the car park! Minutes later a familiar squawk alerted us to a couple of passing Ring-necked Parakeets, our first for at least a couple of years. A female Redstart showed in the hawthorns en route to Whitacre Pool, whilst 2 Whinchats included a smart male in Whitacre Meadow.

Micro Madness

When the thunder rolled in at 1:30am followed by lashing wind and rain, there was a touch of regret/anxiety over setting the traps at Ladywalk. All moths that would have littered the outside of the box had of course scattered but plenty still lurked inside.

It’s very comforting to go down the reserve and see that there are still places with such overwheming diversity and sheer volume of insect life, especially when you’ve been used to trapping in a small urban garden. The amount of micro-moths was impressive, many species probably got away. Tonnes of beetles were in the trap too, double figures of shieldbugs and ladybirds all appeared to be hiding from the storm. How many more moths would there have been if it didn’t rain?

Bank Holiday Moths

 Better than we were expecting with a dip in night temperatures. Nice to see some green in the form of a Light Emerald in the trap again and the second Chocolate-tip of the season. More unusual were firsts for us at Ladywalk with Small Clouded Brindle and Figure of Eighty. They are common moths but glancing through some of the past records they haven’t been recorded, so nice to fill some gaps.

Mini-Orchard Beginnings

 If you’ve visited the reserve in the last couple of weeks and have strolled round to Riverwalk Hide, no doubt you’ll have noticed some newly planted trees. These are the beginnings of Ladywalk’s orchard.

 Inspired by other sites in the county, we would like to collect together varieties of orchard fruit that have their origins in Warwickshire. Granted, Warwickshire has never had a rich orchard history as say Worcestershire has, but we would like to keep these varities alive. So by planting an orchard at Ladywalk we hope to; help maintain variety diversity, provide another valuable habitat and food source on the reserve and perhaps even try some of the fruit for ourselves!

 In spring the trees will be excellent for pollinating insects and generally good for a host of invertebrates year round. It’s well known Bullfinches will enjoy snacking on the buds. Redstarts and other migrants may pop in and as the trees mature they will be valuable to species such as Lesser Spotted Woodpecker and even nesting sites for Little Owls. Of course the fruit will be attractive too. One of the chose apple varieties fruits early in August whilst the other will hopefully hold onto it’s fruit into the New Year providing a good place to see Fieldfares and Redwings on the reserve.

 So far we have planted six trees in two rows of three. The trees have been staked and we’ve done our best to deter the host of creatures that would like to munch on the tasty, young buds by protecting them with a sheath AND a wire fence, but we’ll see. The soil is incredibly fertile and moist so they should get off to a good start. Concerns were raised over the flooding risk but the site was carefully. It does not waterlog like other areas of the reserve and if flooding should occur it rarely lasts longer than a day.

 As for the varieties, we have chosen two ‘Wyken Pippin’ apples, two ‘Warwickshire Drooper’ plums and two native crab apple trees. The apples are grafted onto an M25 rootstock which controls the ultimate size of the tree. M25 is very vigorous and will produce a full-sized orchard tree of up to 4.5m in height and 6m in spread with lots of wildlife value and that traditional orchard feel. The plums are grafted onto a St. Julian A rooststock producing a tree roughly the same height but perhaps less breadth. The crab apples have been planted in the middle of the orchard so that they aid pollination between the different apple varieties and improve fruit set. A few additional crab apples have also been planted around Rudd Pool by an already mature apple tree to provide another fruiting area in years to come.

 Plans are to extend the rows of the orchard to include two of a rare Warwickshire apple variety called ‘Hunt’s Early’ which I couldn’t find to buy ‘ready-made’ so instead had to preorder to be grafted which will take 18 months! I’ve also heard reports of another Warwickshire apple called ‘Shakespeare’ but couldn’t find any details on it. If anybody has any information on this variety (or any others from Warwickshire) we’d love to hear about it and include the variety in the orchard.

 The varieties are listed below. Suppliers used were Walcot Organic Nursery in Pershore, Worcestershire and Keepers Nursery in Maidstone, Kent. Both have provided excellent service and very healthy trees.

Apple – Wyken Pippin

Origins: The pips of an eaten apple from Holland were planted at Wyken Manor near Coventry in the early 1700’s. The variety is an ancestors of Laxton’s Superb.

Description: Flat, round apples with smooth green skin with fine russet dots. Sometimes with some red flush. Juicy sweet and richly flavoured.

Picking time: Mid October

Season of Use:  Can store until January.

Apple – Hunt’s Early

Origins: Warwickshire, 1884. Was commercially grown in Kent.

Description: A sharp, early season apple. Flushed red.

Picking Time: August

Season of Use: Doesn’t keep, use in August.

Plum – Warwickshire Drooper

Origins: Grown commercially in orchards in Warwickshire and believed to be first known as Magnum though there is some uncertainty as many varieties had the word Magnum in. It wasn’t until the 1940’s that it became known as the Warwickshire Drooper.

Description: A small, yellow plum with reddish speckles. A good multi purpose, good for cooking or leave longer on the tree for a sweet dessert plum. The tree’s branches arch downwards hence the name.

Picking Time: Early September.

Excerpt from Forgotten Fruits by Christopher Stocks:

 “It might sound more like an unfortunate condition than a type of fruit, but this gloriously titled plum is actually named after the way it’s branches droop from the tree, almost giving it the look of a weeping willow. Odd growth habits aside, it’s rather handsome yellow, egg-shaped fruits are excellent for cooking and preserving, and at their best they make a decent dessert plum. It was once a popular variety, widely planted in the Midlands and sent to the London markets, but today it is rather rare, and well worth cultivating. In it’s county of origin the fruit was sometimes fermented to make an alcoholic drink know as Plum Jerkum, which was reputed to ‘leave the head clear while paralysing the legs’ and whose exciting effects surely deserve to be rediscovered.”

 For those interested in planting local fruit varieties no matter where they live, I’ve found  the above mentioned title and the The Apple Source Book by Sue Clifford to both be very useful. Planting trees is always a good thing to do but planting local fruit trees will reap many benefits.
