Fifteen visits were made, across the whole reserve in the period between 6 April and 18 August, each visit approx. 5-6 hours in duration. As was the case last year 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 ringing records from Dave Clifton, information from Pete Sofley (reserve warden) and Twitter. I am sure that there are other peoples records that can enhance this report. If so please forward it to me via Richardking54@gmail.com.
The transects are as follows –
Transect 1 – from car park to the double gates
Transect 2 – from double gates to Sainsbury Hide.
Transect 3 – at Sainsbury Hide
Transect 4 – from Sainsbury Hide to Rudd Hide *
Transect 5 – at Rudd Hide
Transect 6 – from Rudd Hide to Riverbank Hide*
Transect 7 – at Riverbank Hide
Transect 8 – from Riverbank 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 –
6 April 16 June
14 April 22 June
21 April 29 June
27 April 6 July
11 May 20 July
18 May 3 August
22 May 18 August
The summer of 2017 did not have the heavy rain and flooding that blighted the 2016 breeding season. April’s weather was mostly dry and sunny with about half the average rainfall for the month. May remained mostly dry and sunny although the rainfall was about average. The dry sunny and warm weather continued well into June with temperatures reaching 30 degrees on several days. There were few wet days and we received about average rainfall. July saw about average rainfall with the first half of the month warm and sunny, with a cooler and wetter second half of the month. August’s weather was variable with average rainfall. There were some periods of hot weather, notably between 25th and 28th but there were often drizzly and overcast conditions.
Summary for the 2017 Breeding Season
Little Grebe appear to have done better in 2017. Pairs were present on both Main and B Pools in April and May. An adult and young bird were seen on Main Pool on 3 August and this or another immature was seen on the 26th. B Pool held 1+2 and a pair +2 also on 3rd August so this date yielded three broods across the reserve.
Again the Fishing Pools seemed the safest breeding environment for this species with an unrecorded group of young birds seen on 11 May and three minute young birds seen on 22 June. A brood were seen here on 7 July and 1+2, presumably from another pair, or second brood seen on 3 August.
Great Crested Grebe pairs were both on Main and B Pools in April and May and there was a nest very prominent on Main Pool, below Riverbank Hide which produced three young birds. However on my visit on 1 June there was a crow consuming one of the young, the crow having stolen the juvenile from an offending lesser black backed gull. Within minutes the same or another gull then took another juvenile, but the remaining youngster survived and was seen on subsequent visits. A pair also nested on B Pool, producing one youngster that was seen on several occasions in June.
Great-crested Grebe (Pete Lichfield)
Cormorants nested in the same location as last year and during my visits I counted between 16 and 20 nests. I suspect there were 17 nests, which may be a little less than in 2016, and by 18 May many held nestlings that eventually found their way to the main pool.
Little Egret was occasionally seen on the reserve but no sign of them breeding here, compared with RSPB Middleton, 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.
Mute Swan On 1 June there was a pair and six cygnets on Main Pool although I had not seen a nest on the reserve. This family were seen on various pools but appeared to lose a cygnet within a few weeks, and this pair + five remain on the reserve as of December 2017.
Canada Goose A successful breeder but nests were not easy to locate. On 21 April there were two nests seen at Main Pool whilst on 18 May there were 126 birds on the meadow including one family, and broods of five and nine goslings on the adjacent pool. Also on this date there was a brood of eight on the river island. On 11 May there was a bird on its nest at Main Pool when there were broods of eleven and seven on the river.
Shelduck None were seen on the reserve after April, when there were one or two pairs with both pairs in conflict with each other on 14 April.
Gadwall appear to have been more successful this year particularly at B Pools. However the first brood was a pair with three young on the river on 27 April. Previously several pairs had been seen on the river, but at B Pools there were 12 pairs on 22 May, with two broods reported on 16 June, and on 22 June there was a brood of nine with the female acting aggressively to a crow. By the end of June, through July and August, birds with broods were regular at B Pools with a report of one having 15 ducklings.
Pete Sofley has reported that there were 12 broods across the reserve producing 100+ ducklings.
Teal Small numbers remained on the Reserve during April, but no sign of breeding.
Mallard Many broods seen with the first being a 1+7 on the river on 27 April Broods across the reserve were as follows-
8 May – female + 8 and 2+6 West Bay; pr + 10 Main Pool
11 May – pair + 3 and female +3 on the river and the above pr with 10 ducklings at Main Pool seen again. 2+9 little ones on the river and elsewhere on the river, 1+5
18 May – 1+8 (Main Pool) and female +9 (river); 1+7 on river; two more broods totaling seven also on the river, 1+5 at B Pools.
22 May – 1+8, 2+3 and 1+10 smaller ones, all on Main Pool and there was a female +8 on the river, prob. the family I saw there on 18th. 1+5 (river)
1 June – a brood at West Bay, and 1+9 and 1+7 at Main Pool; female and 5 five large ones on the river. 1+8 in front of B Hide
16 June- 4 large ducklings on river, 1+7 (Main Pool) and 1+5 (river). The latter has lost two ducklings since 11 May but this number of ducklings remained when I saw them twice subsequently. Also on this date was a large brood at B Pools and two other broods totaling 11 ducklings on the pool as well as 1+7 at the fishing pools
22 June – 1 +4 and another brood (Rudd) and 1+6, 1+5 as well as some older ducklings all on the river. There was a brood of seven ducklings in front of B Hide
29 June – 1+4 (as above, Rudd); 1+8 small ones on the river; 1+2 Fishing Pools
6 July – 1+7 large ones on the river
7 July – 1+7 fishing pools and these seen again here a month later
20 July – family of five at Rudd, 1+5 (river); 12+7 medium sized ducklings at B Pool
18 August – 1+5.
This is an exhaustive list and mirrors a more successful breeding season than last year. Many broods were seen on the river and it is possible that there has been some double counting.
Shoveler were present on the Main Pool in April. They were reported to have bred in the small pools off B Pool and 5/6 ducklings were reported on 9 June and I saw two juveniles on B Pool on 6 July.
Tufted Duck Pairs were regular across the reserve throughout the spring and summer and first breed reported (Twitter) on 22 July. I first saw ducklings on 3 August (female+4, Main Pool) and another brood of seven quite small ducklings on 18 August.
Goosander Adults noted normally on the river, and there were reports of one duckling on 21 April, a brood of seven from 22 May and reference to a third brood, of nine, on 6 June.
Sparrowhawk Only seen occasionally and no evidence that it has bred on the reserve since 2015.
Buzzard Regularly seen on or over the reserve. There was a large nest in a birch behind the lock up and this may have belonged to this species.
Kestrel Unlike 2016 this was rarely seen during my visits and no evidence of breeding.
Peregrine Falcon Calls from young bird(s) regularly in the car park area and they were often on the pylon nearby. I am informed that three fledged from a nest on a nearby warehouse.
Hobby Birds were present on the reserve between August and late September and probably bred locally.
Pheasant This bird appeared less numerous on the reserve this year but unlike last year there was clear evidence of breeding. On 22 June I came across a female feigning injury with a chick nearby on the track at Transect 2. Also a working party had 1+7 below A Hide.
Water Rail Although I saw little evidence of birds on the reserve during spring / summer there were positive reports about this species’ breeding status. Two adults with two/three juveniles were reported at north pool sluice and juveniles seen with adults below Riverwalk and B Hides. It is possible that there were at least three / four breeding pairs.
Water Rail (Pete Lichfield)
Moorhen First family of the year were again on keyhole scrape where there was one juvenile on 18 May which was seen subsequently. Birds were regular on Main and B Pools with 1+3 small ones at the former and at least one small brood (two) seen on several occasions at B Pool. This could have been less successful than last year.
Coot There were two nests at Keyhole Scrape in April and a young bird seen on 11 May
At Rudd Pool – 14 April 1+1 on nest
27 April 3 young left a nest
11 May – Unoccupied nest
18 May 1+1
1 June One on nest in reeds
On 22 June 1+4 small young, a large juvenile and an adult with nest material
29 June – 2+2, a large immature and another nest being constructed
7 July – 2+1
26 July – 2+2 big ones, a large juvenile and further nest building
3 August a young bird on the nest
At Main Pool – 22 May – two nests West Bay
1 June – now four nests
29 June 2+2 small ones
Juvenile seen on river on 6 July
B Pools – – 21 April – nest on raft opposite B Hide
27 April above nest and 1+2
11 May – two broods (2,4) inc. from raft nest
18 May – above 1+4 again seen
22 May – three broods totaling 8 imms.
18 June 1+1
22 June – two large juveniles but only one seen 29th
6 July – two broods of three & four
3 August – about three broods of about eight imms.
Fishing Pools – immature seen on 29 June
Oystercatcher A pair were present at the main pool in April and were seen at a nest on one of the islands on 27 April and 11 May but by 18 May this had been predated. This is at least the third consecutive year when they have been unsuccessful. The birds remained into June including on the 16th when one vociferously mobbed an osprey high over the reserve.
Little Ringed Plover Occasionally seen on the reserve but did not breed there. On 16 June B Pool held four birds inc. three juveniles that had been raised elsewhere. Twitter reports that on 17 July there were four juveniles that had originated from elsewhere.
Lapwing Up to four seen from Riverbank Hide in April / May and one probably on a nest on both on 21 April and 22 May. There is no evidence that these nests were successful, predated, quite possibly by foxes.
Two pairs also recorded at Main Pool on 1 June and by late June / early July up to 50 birds were present – obviously from elsewhere.
Black-headed Gull Up to about 20 birds, including juveniles from elsewhere.
Present in the breeding season and may breed in the future.
Common Tern There appeared to be less of a presence this year but reports of a pair displaying over the main pool may lead to optimism about future breeding and there is a plan to position tern rafts.
Stock Dove These remain regularly across the reserve especially in the line of poplars by the fishing pools. Dave Clifton, ringer, reported that eight nests were in nestboxes across the reserve, but at least three nests failed. (see list below).
Nest Date Comments
1 29/3/2017 2 newly hatched young
13/4/2017 Predated – squirrel
2 29/3/2017 2 warm eggs
13/4/2017 Predated – squirrel
3 29/3/2017 2 eggs
13/4/2017 cold eggs
4 23/5/2017 1 large chick
5 23/5/2017 1 large chick
6 23/5/2017 2 warm eggs
7 23/5/2017 2 large chicks
8 23/5/2017 2 large chicks
Feral Pigeons are also regular on the reserve and a pair nested later in the season in a box near the lock up.
Wood Pigeon Constantly on the reserve, where it is sure to have bred in several locations.
Cuckoo Up to three birds seen or heard on the reserve in April, May and early June, including a female on 11 & 18 May and 1 June. A juvenile reported on 7 August via Twitter.
Tawny Owl Nestboxes were again not used this year and there appears to be no clear information about this species breeding on the reserve. Young birds possibly heard on 29 June between Bittern and Riverbank Hides
Kingfisher Regularly seen or heard along the river. On 27 May one was on the riverbank between Riverbank and Bittern Hides, near to the sand martins’ nests and there were also two heard here on 6 July. They are likely to have nested here and it is possible that one or two pairs nested on or near the reserve, with a report on Twitter of a brood on 9 June.
Green Woodpecker Did not seem to be as numerous at great spotted woodpecker and during April and May the most regular location was in the area of the Fishing Pools, particularly in the poplars there. Young birds heard in a nest in one of those trees on 18 May may have been this species. There may have been a second pair elsewhere.
Great Spotted Woodpecker Regularly seen on most visits to the reserve, including three by the car park on 6 April. Young birds, prob. of this species, were heard from a nest on track towards lock up on several occasions in May, inc. a juvenile nearby. Also young heard in a nest in the poplars at the top end of the reserve. They were also regular on the two bird hide feeders, inc. a juvenile on 3 August by B Hide.
It is likely there were more nests than those listed above – at least four nests?
Lesser Spotted Woodpecker Not encountered by me but there were reports of a pair in the breeding season, inc. carrying food so likely to have nested on or near the reserve.
Swallow Regular over the reserve and on 20 July young birds over Main Pool probably originated from nests at the stables adjacent to the reserve.
House Martin Small nos. of this species over but did not breed at the reserve.
Sand Martin Present on the reserve from approx. 6 April and 30 seen on 14th. More often in the B Pools area and they appear to have nested in the bank between Riverbank and Bittern Hide, where they were seen to gather nest material. They also appeared to nest by the island in the river by transect Two. Difficult to ascertain nesting success as it was not possible to count the holes but unlike in 2016 there were no problems of serious flooding. It is hoped that the nest sites did not become too overgrown.
Grey Wagtail In April, May and June birds were occasionally seen by the river. On 3 & 18 August two juveniles seen by the fishing pools, these were prob. the two young birds reported by the river on 30 April.
Pied Wagtail recorded as a breeder last year but seen less regularly in 2017. Seen by the river most often, and in front of Riverbank Hide on 18 May, plus by B Hide on 6 April and 16 June. An adult with a young bird was photographed near the car park on 1 June.
Wren Numerous with singing birds all over the reserve. Numbers appear about the same as last year when I estimated 24-30 pairs on the reserve. The most birds seen / heard was 36 on 1 June. A family seen at transect 1 on 6 July and 2+2 seen in same area on 3 August. Other families seen transect 8 on 18 May, T12 on 22 May and in the same area a family group of at least three birds on 29 June. 15 were ringed / caught on the reserve.
Dunnock Pairs were often seen together and I estimate at least ten pairs across the reserve on the basis of sightings and song. A family party was seen on 20 July from Hide A and on 18 August two juveniles were seen at T8.
Robin Maximum of 19 birds seen / heard was on 18 May which is an increase over 2016. Juvenile birds were seen at various locations on the reserve on six occasions in June, July and August.
Blackbird Highest number recorded across the transects was 16 on 18 May so this could be the approximate number of pairs. No nests were found although one was seen with food on transect 6 on 22 June.
Song Thrush regular but not in large nos. on the reserve. On 29 June there was the exceptional number of 18 on the reserve but up to seven being encountered across the reserve more typical, suggesting approx.. five breeding pairs. Seen or heard most often in the tall poplars and a pair probably bred between Riverbank & Bittern Hides.
Cetti’s Warbler A good indication of the number of birds on the reserve is that five birds were ringed this year, but in addition there were 15 retraps. Two of these were from 2016, one from 2013 and there was a 2015 bird ringed at Tring, Herts. Maximum encountered on a day was six on 14 April, although one was over the river. They were seen or heard most often at B Hide but encountered at times in all the reedbeds. The ringing report suspected that at least two pairs bred, in or close to the marsh ringing site as three young birds were ringed. At least one pair nested near B Hide as evidenced by a report on Twitter by SLC on 29 May.
Cetti’s Warbler (Pete Lichfield)
Grasshopper Warbler Birds were noted as reeling on the reserve in early and late spring, and again in July which suggested a second brood. It is therefore thought likely that this species bred on the reserve.
Sedge Warbler Ringing information is again possibly of more use in determining true numbers and 19 were ringed this year, with 5 retraps. Regular in the area around Bittern Hide, with a pair seen together on 1 June. Also, like Cetti’s they were regular in front of B Hide with sightings, or heard, on seven dates, inc. at least three on 10 May. Highest count of birds seen / heard across the transects was eight on 18 May.
Reed Warbler 73 birds were ringed, of which 39 were new ringings. Of the 34 retraps/recoveries one remarkably had been originally ringed at Ladywalk in 2006, and there were another 16 retraps originally ringed between 2011 and 2016. It was impossible to record this number through my survey, the most I recorded on a visit was five on 18 May. Quite regular from Rudd Hide and like sedge and Cettis regular at B Hide where one was seen with nesting material on 27 April.
Lesser Whitethroat Not recorded on my visits this year.
Common Whitethroat Highest number in a day was seven on 11 May, a lower number than last year on the same date and they did not appear to be as regular in 2017. They were most common between Riverbank & Bittern Hides, with six in that area on 29 June. Also on this date a family was sighted between Riverbank & Rudd Hides. This species normally give the presence of families away by their alarm calls but there seemed little evidence of this in 2017. Estimate of 5-7 nesting pairs.
Garden Warbler seemed to be loyal and prominent in specific areas of the reserve. For example one was heard regularly over the river between the car park and reserve gate (but not on the reserve) and very likely to have bred by the wooden bridge behind B Hide. A pair were there on 27 April, seen / heard regularly and were still there on 20 July. On 18 May two pairs were seen on T6, with one of the birds holding nesting material and this was the date that most birds were recorded on the reserve – ten. Elsewhere (transect 12) two birds and an immature were seen on 3 August. It appears that about four pairs bred on the reserve.
Blackcap Again this was the most numerous summer visitor with 21 birds seen or heard on 1 June, and the high number was reflected by 17 birds being ringed. From my observations strongholds inc. beside the track between the car park and reserve gate eg six birds and two pairs on 27 April, a juvenile on 29 June and a family on 6 July. They were often in good numbers along the river, a male was seen with food on 1 June between Rudd & Riverbank Hides where they were consistently found. In the same area there was a female and juvenile on 20 July. 15-20 pairs across the reserve again this year?
Chiffchaff Second most numerous summer migrant with 12 birds recorded across the reserve on 21 April, but some of these may have been passing through. 11 on 6 July may have been birds going in the opposite direction. There were 6 birds ringed / retrapped on the reserve. There seemed to be quite strong evidence of successful breeding with families seen on 22 May (T1) and a likely juvenile in the same area on 6 July. A pair prob. nested beside the path to Riverbank Hide and a family was seen twice in this area in August, which may have been a second brood. A family of four was seen in T12 on 6 July and during this month and August there seemed to be a number of chiff-chaffs making contact calls. 6-10 pairs across the reserve?
Willow Warbler Not as common on the reserve as 10-20 years ago and a maximum of ten birds seen / heard during the peak breeding season (11 May) across the reserve. This number may reflect the breeding numbers, rather than the 12 encountered on 18 August when there appears to have been an influx, as evidenced by contact calls between Riverbank and B Hides and a mixed flock inc. this species with chiff-chaffs and tits.
Goldcrest Heard on several occasions, and no evidence of breeding. Interesting that one was ringed this year.
Long-tailed Tit Undoubtedly bred on the reserve as evidenced by family groups regularly seen in many areas. There was an agitated bird behind Riverbank Hide on 21 April, which suggests breeding there and they were often present in this area. Nine birds ringed or retrapped.
Five-seven breeding pairs?
Marsh and Willow Tit There is information that both species bred, and have remained on the reserve into winter, using the feeders. Willow Tit seen in good habitat on 18 May and a pair in same location four days later and another probably in same location on 16 June. One of each species ringed.
Willow Tit (Pete Lichfield)
Coal Tit Seen most regularly in the birches between the lock-up and A Hide and one seen gathering nest material at the latter location on 6 April. Another location where quite regular was in the vicinity of B Hide such as a pair on the feeders. On 14 April. As there was not a great distance between these two areas and I never encountered more than two birds on a visit it is possible that the reserve only held one breeding pair.
Blue Tit 24 broods (164 pulli) ringed from nestboxes (average 6.8 per nest), with a total of 209 birds ringed / caught inc. retraps. My records inc. birds seen at nestboxes, nos. of family parties and juveniles across the reserve, inc. at the feeders. The most unusual nest site was in the roof of Rudd Hide which produced one brood in the nest for much of May. Ringing records for this species are as follows –

Nuthatch Regular on the reserve, partic. at the feeders at B Hide where recorded on eight visits. One or two pairs bred. On 16 June I saw a probable juvenile at T2 and SLC reported two, nearby, by reserve gate earlier in the month. Not far away is Transect 12 where I saw a brood of at least four on 6 July.
Treecreeper Encountered more this year than in 2016 – bred in the area of the main gate as in song on 27 April, one or two seen on 22 June and a juvenile on 6 July. Heard on at least three visits in the copse between Rudd and Riverbank Hides and a juvenile seen here on 22 June. Two birds in the copse behind B Hide and heard in this area or along the poplars four times in June – August. One heard in Transect 12 on 16 June, where a juvenile seen on 29 June. Two were together inc. at least one juvenile on 3 August and two were in a mixed flock here on 18 August.
The reserve has many areas of woodland that are suitable for this species and with the additional information that there was also a presence between Riverbank and Bittern Hides it is quite possible that three or four pairs bred.
Jay I saw less evidence of this species across the reserve in 2017 but it is possible that at least two pairs bred. Most commonly seen from or near Sainsbury Hide with two juveniles on 29 June and I am likely to have seen two, possibly the same birds, the following week between Riverbank and Bittern Hides. An immature at T12 seen on at least one occasion and with SLC reporting seven on the reserve on 3 August there was undoubtedly a breeding presence, perhaps two pairs.
Magpie Probably bred at transects 1 & 12 where there are the biggest trees. At the former singletons or pairs seen on five occasions, before a family seen on 6 July, whilst at T12 there was a young bird with an adult on 16 June. There were other sightings elsewhere including on the feeders. Possibly two pairs bred?
Jackdaw Small numbers regularly seen esp. on the grass opposite Riverbank Hide with 15 recorded here on 16 June. No evidence that they actually bred on the reserve.
Carrion Crow Singles or pairs seen across the reserve and an occupied nest above the track on 14 April. One or two pairs prob. bred on reserve.
Raven In 2016 a pair nested on a pylon in meadows the other side of railway / access road to fishing club but I received no information about breeding this year.
Starling Pete Sofley reported two starlings’ nests by 11 May in the willows near to the ringing area (T8).
Chaffinch Not very common on the main reserve but regular at feeders at A&B Hides. Birds were present during the breeding season, with five the maximum. I saw no evidence of breeding but it is possible that two or three pairs bred.
Greenfinch There appeared to be more of this species around the feeders during the breeding season and into the winter. Hide A feeders held most birds, inc. pairs, on most visits, with courtship seen on 11 May. On 20 July a juvenile was seen and on 3 August there were six juveniles in a party of ten, and on the 18th there were three juveniles. On the basis of this one or two pairs may have bred on the reserve.
Goldfinch Pair at the car park feeders on 14 April and small numbers of birds seen or heard throughout the season across the reserve. I saw no evidence of breeding this year but it is possible that one or two pairs may have bred on the reserve.
Linnet As last year, birds most numerous in the area between Riverbank & Bittern Hides, although this year they were more noticeable on the reserve side of the river. No more than four (two pairs) were recorded and a juvenile was seen between the two aforementioned hides on 6 July. It is likely that one or two pairs nested on the reserve and probably a similar no. over the river.
Bullfinch This species seen in most areas of the reserve especially where there is more woodland. Transect one, where regularly seen and heard, held two males and a female on 6 April and a pair the following week. Birds were regular at the Riverbank feeders and likely to have bred nearby, between the latter hide and Rudd, where on 20 July at least three, prob. five were seen together, clearly a family party. On the following visit several birds inc. a juvenile were present. Three / four pairs nested again this year?
Reed Bunting A maximum of six birds encountered on 11 May and numbers recorded were lower than in 2016 although well scattered. The reedbeds between Riverbank and Bittern Hides was most regular with birds heard or seen on nine visits inc. two birds and a juvenile on 20 June. Perhaps there were approx. 6 breeding birds?
Duck breeding was more successful than 2016 with increased nos. of Gadwall and Tufted Duck ducklings and Ladywalk could be the only location in Warwickshire at which shoveler successfully bred. The big gap appears to be the lack of waders breeding and predation seems to be the reason for this. It is possible that Lapwings attempted to nest and Oystercatchers nested on an island but that nest was predated. Whether Crows, Lesser Black-backed Gulls or foxes take the eggs we do not know although a fox scouring the islands on the day of the May bird count did not augur well. We are not sure whether the deeper channels that have been dug around some of the pools and islands will deter them. It is possible that we will have to consider some fencing but that is not easily implemented and could be expensive.
As for smaller birds Wrens are doing well as are Robins. Whilst I am using only two years’ records, Whitethroats and Reed Buntings seemed to be less numerous, but Blackcaps continue to do well. It is pleasing that there has been a continued presence of Willow Tits, and Coal Tit and Nuthatch both appear to have done well on the reserve. Finally there is little more pleasing than the Song Thrush in song and their numbers appear static.
