May's exceptional showing by Sanderling continued with a final bird on June 1st. A late Dunlin was also seen that day with returning birds on July 5th and 17th. Single Curlew flew over on June 29th and July 8th. It was also a very good summer for Redshank with singles on June 2nd, 3rd and 6th with two on 14th with records in July on 13th, 19th, with two again on July 25th and 30th. There had only been two records last year by the end of July.

Reservoir Logs - May 2023 round-up
May produced quality birds from the beginning to the end of the month with flocks of both Sanderling and Turnstone the highlights. In another blaze of colour, the month also saw Black Terns, Black-necked Grebes and Garganey along with Ringed Plover and Hobby added to the year list.

These eight additions in May take the year list to 127, ten more than last year and three more than in 2021. Wigeon is - inexplicably - the big miss so far but the Wetlands might also have expected to have recorded Greenshank and Black Redstart already. Far more serious is the fact that for the second year running Avian Flu is infecting birds at the Wetlands. This summer it is Black-headed Gulls and Cormorants that seem worst affected.
For the second successive year, Barnacle Geese have hatched young on No 5. Four young were initially seen with one quickly lost but the remaining birds survived until the end of the month.They could usually be found around the No 4/5 causeway close to the trout fishermen who not only share their sandwiches but also provide some protection from marauding foxes. Another pair appeared to be trying to breed on the big island on No 5 but there has so far being no sign of any success.
It looked as if Spring was going to pass without any Garganey being seen until MLP photographed a stunning drake on No 3 on the 24th which stayed for the day. Shoveler are often missing in May but up to four were seen from the 20th. A Teal was also an unusual record for May with a drake seen for a few days in the middle of the month on No 3. After arriving in early January, the drake Scaup was last seen on the 5th, the latest a wintering bird has stayed in recent years.
As the wintering Scaup departed, the breeding ducks began to produce young. The first Tufted Duck family were seen on the 22nd - three weeks earlier than last year - with at least a couple of Pochard broods as well before the end of the month along with a Gadwall family.
Superb Black-necked Grebes were seen on two days pic @EugeneDH_BassA stunning Black-necked Grebe was found on Lockwood on the 12th and came so close it could be heard singing. It, or another, also appeared on East Warwick on the 28th. Two Great White Egrets were recorded with one flying over No 4 on the 13th and a second over Lockwood on the 27th. At least 22 Little Egret nests were found in the breeding survey this month. This is three down on last year's total but the team were unable to carry out a full second survey so nests may have been missed.
Red Kites were seen on the 15th and 28th compared to five days last year while Buzzards were slightly more frequent with records on the 13th, 14th and 28th, one more day than in 2022. Hobbies dashed over the reservoirs on the 4th, 9th, 12th and 27th.
Hobby was a scarce visitor to the Wetlands this month pic @magusphotog
May saw an excellent ten species of waders at the Wetlands with the persistent and strong northerly winds extending migration right to the end of the month. Just like last year, there was only one record of Lapwing with a single on the 23rd. Oystercatchers were slightly more common with one on the 3rd, two on the 11th and one on 13th although the Song Thrush at the north end of Lockwood which does a wonderful imitation suggested they are passing over all the time....
Both Ringed (above) and Little Ringed Plover were seen pics @Chris_Farthing |
The first two Ringed Plover of the year were seen on Lockwood on the 13th - six days later than the only record last Spring - with a single on the 22nd. Single Little Ringed Plover were seen on the 3rd, 27th and 31st compared to no records last year. Black-tailed Godwit are more normally an early Autumn bird at the Wetland but CF had the first record of the year flying over on the 3rd.
Five Turnstone enjoyed the small area of shingle on Lockwood pics @magnusphotogSanderling had been considered a rarity at the Wetlands with records in only four years in the previous decade before five turned up together last May. But in a month when this charismatic wader seemed to drop down on lakes and reservoirs across the country, this count was surpassed. The first bird appeared in front of those watching the Black Terns on the 27th before seven - the biggest flock anyone can remember - were seen together at the south end next day. In contrast, it was a blank month for Dunlin when there were four records in May last year.
May saw a prolonged passage of Common Sandpipers pic @Elliott81758817After poor numbers of Common Sandpiper in April, May was better with records right until the last day. This is 11 days later than the final Spring bird last year and three days later than in both 2020 and 2021. Another sign that migration was held up by the weather was that while the peak count of nine was the same as last year, this May it was on the 27th rather than the 1st. The only Green Sandpiper was seen on the 3rd, one day later than the final record last year.
Black Terns performed superbly (above) pic @magnusphotog & EugeneDH_Bass
There were again welcome signs that Cuckoo are getting commoner with three more sightings after April's first record. Silent birds were seen on the 7th and 22nd with the wonderful sound of a male calling on the 16th. Kingfishers continued to show well with the pair nesting on the small No 5 island regularly taking fish to feed their youngsters by the month end.
While the northerly airflow undoubtedly extended wader passage at the Wetlands it didn't seem to drop many smaller migrants on the reservoirs. Small numbers of Swallows continued to be seen with ten on the 4th and four still on the 15th. The last Willow Warbler in a good Spring for the species was on the 12th and the final Whinchat on the 2nd, one day later than last year. The disappointing Spring for Yellow Wagtails continued with just two on the 2nd and one on the 4th the only records. Wheatear passage was light but again prolonged with singles still seen on the 25th and 30th.
Wheatear and sleeping Egyptian Goose pic @alanrevelThere was, however, plenty of bird song with Common Whitethroats, Blackcaps, Chiffchaffs and Reed Warblers marking out their territory across the Wetlands. Three singing Lesser Whitethroats - the same as last year - were also heard while a second Garden Warbler sang for a few days in bushes between the Warwicks. None were seen until June last year. But sadly it seems as if the rooting out of the brambles along the banks of both East and West Warwick has led to a reduction in Sedge Warblers across the site with only around half of last year's 10+ singing birds.

Reservoir Logs - March 2023
The 1W Kittiwake took a liking to East Warwick pic @AMP
In all, 19 species - four more than last March which was no slouch - were added to the year list which now stands at 101. This is well ahead of last year's 93 and also the previous three years but still behind 2018's rarity-filled 107. Among the obvious gaps are Wigeon which may now have to wait until the autumn to be seen but Redshank and Dunlin are expected any day.
Ring Ouzel enjoying the rare sunshine this March pic @magnusphotogAfter a couple of weeks at their northern home at Fisher's Green, Barnacle Geese returned to the Wetlands with seven on the 19th and 13 on the 23rd. Two or three including what seems likely to be the bird ringed last year then took up residence with behaviour which suggests breeding might happen again. Four or five pair of Shelduck also seem to be getting ready noisily to breed so let's hope they - like the Barnacle Geese - don't lose all their young again to predation as both species did last year.
The drake Mandarin's visit was typically short pic @IvorHewstone But for the wader-fest in December when up to four were seen daily, the Jack Snipe found on the 2nd would have caused far more excitement. It stayed faithful, when water levels weren't too high, to the channel in the No 1 reed-bed until the 7th although it could be a devil to pick out even when you knew were it was. Presumably the same bird was seen to fly in to the reed-bed on the 12th. Common Snipe was seen on the 1st, 3rd and 11th while the only record of Green Sandpiper was on the 8th. This was a better showing than Common Sandpiper, a regular winterer, which has yet to be seen at all this year while this was the first March since 2019 without an Avocet being recorded. The Kittiwake was a bonus for those twitching the Alpine Swift @TheCowboyBirder
Given the panic a rarity can induce, RE showed admirable calmness in picking out a 1W Kittiwake among all the Black-heads on East Warwick as he rushed round to see the Alpine Swift on the 26th. Once a very scarce bird at the Wetlands, it seems to be getting commoner here with records in the last three years compared to just two in the previous ten. It clearly found East Warwick to its liking as it stayed into April. Also becoming commoner are Barn Owls with the bird found by CF on the 9th the third month in the last four the species has been seen on the south side of the site.
It was also the rarest bird to turn up at the Wetlands since 2018 and, having kindly arrived on a Sunday, attracted birders from far afield as it fed high over the south end of the complex. It was still around next morning but, after going even higher than usual around 1330, disappeared north east and was not seen again.
Ring Ouzel is just about annual at the Wetlands but usually lives up to its reputation for being wary. This was eventually not the case with the cracking male found by PR on the 30th which became more showy as the day went on. While the Ouzel was making its way from its winter quarters north, the odd wintering Redwing and Fieldfare still remained at the end of the month..

After a good movement of Stonechat last month, March saw another pulse of migrants with six on the 10th, five on the 14th and a single on the 24th. Spring does not really start until the first Wheatear arrives. LB won the prize for finding the first on Lockwood on the 14th - eight days earlier than last year - on a day when birds appeared across London. There were also sightings on seven following days with three on the 29th.
One of at least four Rock Pipits this month pic @Chris_Farthing
Rock Pipit is a regular Autumn visitor to the Wetlands but only occasional in Spring. This month, however, saw an unusually strong passage. After the first on the 6th on the No4/5 causeway, birds were seen daily until the 14th. Two were seen together on both the 12th and 14th but photographs show that at least four individuals birds passed through. Brambling is also a scarce but regular visitor in Spring with CF finding a male at the south end of No 3 on the 28th. At least one Siskin, another species which should appear more often, was seen feeding in alders on West Warwick and the Coppermill on the 30th.
