The period’s weather was dominated by a slow-moving low pressure system to the north of the UK, delivering west to south-westerly winds and showers throughout, resulting in a somewhat tepid week, birdwise. While it’s commonplace for migration to take a dive as spring fizzles out, the last week of May has, over the years, been known to produce the stuff of legend in the county. Etched into the memories of those of us of a certain age will be the hallowed 29th, which has delivered Bridled Tern, Sooty Tern and Buff-breasted Sandpiper – rarities of the highest eminence, the likes of which may never be seen locally again …
However, the week’s best birds were rather more down to earth, exemplified by the idling drake Red-crested Pochard still present throughout the period at Earls Barton GP.
Avocets were again well represented with nine at the above locality on 30th and twos at Lilbourne Meadows NR from 24th to 27th and at Clifford Hill GP on 27th-28th.

A Grey Pover spent the afternoon and evening at Summer Leys LNR on 29th, the same site having produced a Sanderling on 25th, when one also visited Lilbourne Meadows.

Lilbourne Meadows also held on to a Tundra Ringed Plover until 27th, while a Greenshank at Pitsford Res on 24th is likely to be the last one for the spring which has seen an unusually good run of them throughout.
The same cannot be said for Kittiwake, an adult – and the first for 2025 – putting in a brief appearance at Thrapston GP’s Titchmarsh NR on 28th before heading off south. This year is fast shaping up to become possibly the worst in recent history for the species … A couple of late Caspian Gulls included one at Pitsford on 24th and a first-summer on floodwater at Braunston on 29th, while Pitsford produced the week’s Yellow-legged Gulls, with two there on 27th and one on 28th.
Bitterns continued to be seen at Summer Leys, where there were two on 25th and single birds on 26th and 30th. With Cattle Egrets up and down of late, five were at the highly favoured North Lake of Stanwick GP on 25th and one dropped in at Clifford Hill on 28th.

Rounding off this week’s raptors and all, single Ospreys graced the skies over Earls Barton on 24th and Pitsford on 28th-29th.
A warm, southerly airstream in the early part of the week was followed by sustained, cool northeasterlies and easterlies in the latter part of the period, although the weather appeared to make little difference to what was on offer on this week’s birding platter …
New in for the back end of the year, though, was a Pink-footed Goose with Greylags at Naseby Res on 17th. It was not seen subsequently. There is always some doubt over the provenance of lone individuals in the county, so should it be considered a wild bird? Why not! With arrivals touching down in the UK as early as late August, Pinkfeet have been returning for the winter in considerable numbers over the past week or so, including some stragglers well inland. Birdtrack had also seen a big spike in reporting rates by mid-month.

Another bird frequently kicked into touch by some is the annually returning female Ruddy Shelduck – this week having now apparently vacated Stanford Res for Ravensthorpe Res, where it was seen on 15th. Stanford’s two Red-crested Pochards, found on the last day of the previous week, quickly tripled to six during the period, all of which remained until the week’s end.

A Common Quail was reportedly flushed in a field west of the River Nene between Nassington and Elton on 14th.
Having notched up almost four weeks at Clifford Hill GP, the moulting adult Black-necked Grebe remained there until at least 15th. Another – in full winter plumage – was found at Daventry CP on 19th but was not seen thereafter.
This week’s waders were in short supply. Stanwick GP produced a Black-tailed Godwit from 15th until 19th, two being present on 18th. Further up the Nene Valley, three Greenshanks dropped into Summer Leys LNR on 15th.
With only five so far this autumn, Mediterranean Gulls have to date proven scarce, so one flying over Raunds on 16th was a welcome addition to the seasonal tally. Apart from that, the usual two larger larids continued to provide some interest. The week’s Caspian Gulls comprised a first-winter at Boddington Res on 16th, an adult at Stanwick on 17th, a juvenile at Daventry on 19th and the habitual German-ringed adult at Naseby on 17th and 20th. Easier to catch up with, Yellow-legged Gulls maxed out at nine in the roost at Boddington on 16th, while five were at Stanwick on 17th with just one there on 18th and Pitsford Res held up to four between 17th and 20th. Elsewhere, single adults visited Thrapston GP’s Titchmarsh LNR on 17th-18th and Daventry on 19th.

Compared to last week it was a different one altogether for Bitterns, with reports from three – dare we say ‘widely spread’ – localities. On 15th, two were together on Summer Leys’ Scrape while, four days later on 19th, one was found at Stanwick, followed by another at Stanford the next day – a ‘patch tick’ even for some seasoned birders over that way.

Meanwhile, Cattle Egrets seem to have slumped back into their periodic low profile status, with one in flight over Raunds on 15th, followed by two at nearby Stanwick on 17th-18th.
And in the first week with no Ospreys for a long, long time, numbers of Marsh Harriers were also down. One flew over Titchmarsh LNR on 15th, Summer Leys hung on to one, seen on 15th and 20th, one was at Wadenhoe Water Meadows on 16th and another in the Brampton Valley between Cottesbrooke and Hanging Houghton on 16th and again on 18th. After one last week, sightings of Hen Harriers increased to three, with an adult male flying east at Blueberry Farm, Maidwell on 14th, a ‘ringtail’ west over Borough Hill on the same date and another ‘ringtail’ over Harrington AF on 16th.
The first Merlin of the autumn, a juvenile, was seen at Boddington on 16th.
On the passerine front, Common Redstarts continued to melt away steadily, with singles at Borough Hill on 15th, in the Brampton Valley on 16th and at Boddington on 17th. Whinchats were still very much in evidence, though, with six localities producing numbers between one and four during the period. Top sites in the latter respect were Borough Hill, where four were present on 16th and at least one the following day, and the Brampton Valley, which produced a maximum of four on two dates between 14th and 18th. Elsewhere, Clifford Hill GP held on to at least three from last week between 14th and 16th, two were at Harrington AF on 14th, two were found at Priors Hall, Corby on 16th and one was at Pitsford Res on 14th. The number of Stonechats continued to rise, although no more than two were seen at each of the six localities of Borough Hill, Brampton Valley, Clifford Hill, Harrington, Priors Hall and Summer Leys.

Northern Wheatears reverted to their former scarcity with one at Borough Hill on 15th and 16th and one at Harrington on the latter date.
