Under the influence of a predominantly south-easterly airstream, the past week remained dry with daytime temperatures gradually falling from the highest of 11 ºC on 8th to the lowest of 1ºC at the week’s end. Much of the previous week’s fare stayed put, providing plenty of opportunities for birders to play catch-up with any birds missed during the preceding period. Again, the spotlight was firmly on Pitsford as the place to be.
Seemingly now settled at Pitsford Res, the adult Bewick’s Swan remained throughout the week, as did the eleven Whooper Swans, now in their seventh week on site. Also staying put was the first-winter on Elinor Trout Lake at Thrapston GP, while another visited Stanford Res briefly on 14th.

Stanwick GP continued to play host to all of this week’s geese – the Pink-footed Goose on 9th, six White-fronted Geese on 14th and the Barnacle Goose until at least 11th, while the female Ruddy Shelduck remained north of the causeway at Pitsford Res until at least 11th. The drake wigeon resembling an American Wigeon x Eurasian Wigeon hybrid came under the spotlight this week and is now considered most likely to be a hybrid between Eurasian Wigeon and Gadwall.

Whatever its genetic composition, it’s still an unusual and striking-looking bird. Red-crested Pochard numbers had fallen this week to a maximum of just four at Pitsford Res on 8th, when the lone drake was also seen at Hollowell Res. Over at Thrapston, the first-winter Scaup was still present on 13th and the genetic purity of the female – perhaps a first-winter – at Ditchford GP was the subject of some discussion on 8th. After initially proving elusive, Pitsford’s drake Ring-necked Duck finally gave itself up to photographers – even to the point of showing off its ring. Remaining principally in Scaldwell Bay, it still occasionally proved tricky to get to grips with.



Also in Scaldwell Bay, a dapper drake Smew – the first of the winter – was discovered on 10th but it was nowhere to be seen beyond 11th.
At the opposite end of Pitsford, the juvenile Great Northern Diver remained throughout the week, often appearing close to the dam.


Bitterns have been scarce so far during the autumn and early winter period and in line with sporadic occurrences, Stanwick produced another drop-in at dusk on 11th. Rarer, though far easier to see, were the two Cattle Egrets at the same locality, while Pitsford also attracted one, albeit briefly, on 12th. Seen well with a small herd of cows below the dam, this constitutes a ‘first’ for the reservoir. Elegant, though somewhat less exciting, up to four Great White Egrets continued to be seen at the same site, while Stanford Res and Stanwick mustered three a piece, Thrapston hosted two and Ditchford GP, Earls Barton GP, Hollowell Res, Ravensthorpe Res and Summer Leys produced singles during the period.

Harriers were the only raptors of note this week and these included last week’s male Hen Harrier, ranging over farmland at the north-eastern extremity of Stanwick GP on 10th, 11th and 13th and a Marsh Harrier over Summer Leys LNR on 13th.

Pitsford continued to host last week’s Ruff until 8th, as well as an adult Yellow-legged Gull and two adult Yellow-legged Gulls were at Hollowell Res, also on 8th.
A ‘new’ Short-eared Owl was discovered at the north-eastern end of Stanwick GP on 11th and the two Bearded Tits were still present at a site with no public access on the same date, while a single Crossbill flew east at Ditchford GP on 14th.







Another first for the winter, a juvenile Great Northern Diver, was discovered off the dam at Pitsford on 1st before promptly being joined by another there on 2nd. Although both were seen together on the latter date, only one has been reported subsequently, right through to the end of the period.












The three Cattle Egrets at the north-east end of the Stanwick GP complex were once again joined by a fourth on 21st-22nd, while one or two Great White Egrets continued to be seen at this and six other locations, Pitsford topping the bill with four on 21st-22nd.




















The species was formerly a more regular, though scarce, winter visitor to Northants but its appearance in the south, east and central parts of the UK is now much less frequent than it was during the last century. In fact, this is the first in the county since 1999. Others were seen inland during the period in Cambridgeshire, Leicestershire, Lincolnshire, Nottinghamshire and East, South and West Yorkshire. More readily accessible and guaranteed to delight, however, were two Bearded Reedlings, which were discovered at Stanwick on 4th and did the decent thing of posing well for photos until at least 6th.







Close examination of the excellent images obtained by Alan Boddington and Bob Bullock enables individuals to be readily identified by their head patterns, which are quite variable. Because of the broad, pale feather fringing on the wing coverts, the ‘long staying six’ (A to F) can be aged as first-winters and at least two of these (B, D) are young males, the dull yellow areas being visible on their bills. None of the other four shows the slightest hint of yellow but C, E and F are showing pale horn-coloured areas on, or around the sides of the nail. This is interesting because, according to Reeber (Wildfowl of Europe, Asia and North America, 1995), this is a characteristic associated with adult females and not present in first-winters.
The ‘short staying two’ (G, H) are adult females with uniform dark plumage, which includes, most importantly, the belly – visible in the only flight shot (below) obtained so far. First-winters have a pale belly until adult plumage is acquired later in the winter or during their second calendar year. Hopefully, the remaining birds will continue their stay at Thrapston for some time to come.












Nene Valley locations continued to provide the focus for more interesting birding, with Stanwick producing a Bittern on its A45 Lay-by Pit on 30th, while continuing to host the two the two Cattle Egrets until at least 31st. The same locality also held a Great White Egret from 27th to 29th and reports of singles seen intermittently came from Clifford Hill GP, Summer Leys LNR, Thrapston GP, Hollowell Res, Ravensthorpe Res, Stanford Res and Sywell CP but Pitsford claimed the lion’s share, with possibly as many as six on 27th and certainly at least four on 2nd.





There were no ‘high’ counts of Great White Egrets during the period and, apart from two at Stanwick GP on 25th, singles could be found at Abington Meadows/Clifford Hill GP, Daventry CP, Hollowell Res, Pitsford Res, Stanford Res and Summer Leys.










Exuding brute and charisma, this Bonxie was a welcome catch-up for local birders, being the first in the county for nine years. And they seem to be getting rarer. This species is now occurring less frequently than it did in the last century, when it appeared in seven out of ten years during the 1980s. This week’s individual was the twenty-first for the county.
