The UK was sandwiched between a low pressure system to the southwest and a high pressure system over Scandinavia, producing a steady southeasterly airflow across the country throughout much of the week, turning southwesterly toward the week’s end.

The Pitsford female Ruddy Shelduck was present on 29th and then went unreported until 4th, when it was joined by a drake.

Twelve Pintails were also present there on 29th with four there on 4th, three were at Stanwick GP on 30th with one there the following day, three visited Summer Leys on 1st and one was found at Hollowell Res on 4th. There were just two records of Garganey with two at Clifford Hill GP on 30th and one at Ravensthorpe Res on 4th, while diving ducks were represented by an eclipse drake Red-crested Pochard at Stanford Res on 28th, a short-staying juvenile Scaup at Boddington Res on 3rd and a Goldeneye at Stanford Res on 28th with two at Earls Barton GP on 1st.

No longer a head-turner, a Great White Egret was found at Ditchford GP on 2nd, remaining until at least 14.00 the next day, while another arrived at Thrapston GP’s Barclaycard Pit during the morning of the same day. With an established North European population this species seems set to follow Little Egret in becoming a common sight in the UK. More welcome in the county, however, would be another Glossy Ibis, which has appeared only on two previous occasions (September 2002 at Ravensthorpe Res and September 2010 at Pitsford Res) each staying no more than twenty minutes. With western Britain currently enjoying another mini-invasion another is surely on the cards … On the raptor front a Marsh Harrier was again at Harrington AF on 30th and a Peregrine was at Summer Leys on 1st, while two were circling over Oundle on 3rd.

A few new waders arrived this week. A Little Ringed Plover was found at Pitsford Res on 4th, where eight Ringed Plovers were also present on 29th and 30th, dropping to four by 4th, while up to three were at Clifford Hill GP between 29th and 3rd. There was also a mini-influx of Grey Plovers, which included singles at Hollowell Res and Stanwick GP on 28th – the latter remaining all week – Pitsford Res on 29th and Daventry CP on 30th

and numbers of Golden Plovers started to build with forty-nine at Clifford Hill GP on 2nd and twenty-four at Stanwick GP on the same date. The latter locality also produced two Little Stints from 29th to 4th. Dunlins were found at four localities with site maxima of 4 at Daventry CP on 30th and the same number at Pitsford Res on 2nd, three at Clifford Hill GP on 28th and two at Stanwick GP on 3rd. The only Ruff this week were up to two at Clifford Hill GP between 28th and 3rd while the second Jack Snipe of the autumn was found at Daventry CP on 2nd and last week’s two Bar-tailed Godwits remained on the new scrapes at Thrapston GP until 29th. Just one Common Sandpiper was found – at Pitsford Res – on 29th when there were also three Green Sandpipers on the same date followed by singles at Daventry CP on 2nd and Ravensthorpe Res on 4th.

The only Mediterranean Gulls this week were at Boddington Res, where there were two first-winters on 2nd and one on 3rd. The same cannot be said for Yellow-legged Gulls, which maintained high numbers almost daily at Stanwick GP with a maximum of more than one hundred and ten there on 30th; elsewhere three were at Ravensthorpe Res on 4th, up to two were at Pitsford Res all week and singles visited Boddington Res on 3rd and Hollowell Res on 4th.

Good numbers of Caspian Gulls were also recorded this week with one at Stanwick GP on 29th, five there on 30th, three on 1st, four on 3rd and four on 4th. Four were also at Ditchford GP on 28th and 30th.

Winter came one step closer this week with the arrival of the first Redwing, which was trapped and ringed at Stanford Res on 28th, while a Whinchat remained at Clifford Hill GP on 28th and single Northern Wheatears were at Harrington AF on 28th and 30th and at Clifford Hill GP on the last of these dates.

A light westerly airstream dominated the first part of the week with a low pressure system in the eastern Atlantic bringing southwesterlies to the UK. This gave way to a Scandinavian high pressure system and a resultant easterly airstream out of Europe towards the week’s end.

The Pitsford Ruddy Shelduck remained throughout the week, continuing to fuel debate about its origins and the same site hosted the only Pintails of the week, three on 21st with a Garganey there on the same date. Single Garganeys were also at Clifford Hill GP on 20th and at Summer Leys on 21st with two there on 26th and one on 27th and the long-staying Goldeneye at Pitsford Res was joined by two more there on 21st.

A juvenile Marsh Harrier was again at Blueberry Farm, Maidwell on 22nd, followed by an adult male at Harrington AF the next day, while an Osprey visited Thrapston GP on 22nd and another flew west over Hardingstone on 25th. A male Merlin was at Blueberry Farm, Maidwell on 22nd and single Peregrines were seen there on 21st and at Summer Leys on 26th – a juvenile female – and 27th (an adult).

A better selection of waders was evident this week, although numbers of each species were relatively low. Ringed Plovers were the exception, though, with eighteen at Pitsford Res on 21st comprising four on the ground and a separate flock of fourteen flying over. The four on the floor had increased to seven by 24th and then reduced to five from 25th to 27th. Elsewhere one was at Clifford Hill on 21st and five were at Summer Leys on the same date, dwindling to four on 23rd and one on 26th-27th. After flagging up last week the complete absence of Little Stints this year one promptly appeared at Clifford Hill GP on 21st, quickly followed by another at Pitsford Res on 27th.

The Clifford Hill bird was accompanied by two Dunlins, another Dunlin was at Hollowell Res on 24th and, back at Clifford Hill, three were present on 27th, where there were also two Ruff on 21st and three on 27th, with further singles at Pitsford Res on 21st (two on 22nd), Wicksteed Park Lake on 25th and Summer Leys on 27th. The first Jack Snipe of the season was found at Bozeat GP on 26th, the same date that the week’s only Black-tailed Godwit was found at Summer Leys. Two Bar-tailed Godwits – unusual in the county in autumn – visited Thrapston GP on 21st and were still present there the next day and a Curlew flew over Pitsford Res on 27th. Common Sandpipers became scarce with just one at Pitsford Res on 21st and two at Daventry CP on 26th and the only Green Sandpiper of the week was one at Summer Leys on 27th. Another scarce visitor which is only just annual in the county was a Spotted Redshank on 21st at Pitsford Res where it joined up to two Greenshanks present until 25th and a Redshank was also there on 23rd.

Rare larids ramped up this week, producing potentially the rarest bird of the year so far. An adult Azorean Yellow-legged Gull appeared in the Stanwick GP main lake pre-roost around six o’clock on the evening on 27th before flying off toward the A45 Lay-by Pit shortly afterward. This race is not (yet) officially on the British list and reported occurrences here are always controversial and generate much debate. At least one hundred and thirty-five Yellow-legged Gulls were also present on the same date – a new Northamptonshire record count! Others included up to three at Pitsford Res between 23rd and 27th with one at Boddington Res on the latter date, while Stanwick produced three Caspian Gulls – also on 27th – and a juvenile was at Daventry CP on 26th with an adult there on the following date, when a first-winter Mediterranean Gull was also there.

A Short-eared Owl was again at Blueberry Farm, Maidwell on 21st as were up to six Whinchats until 24th. Two more Whinchats were at nearby Harrington AF from 21st to 23rd and another was found on the ‘chat fence’ behind the Premier Inn at Clifford Hill GP on 27th. A single Northern Wheatear at Harrington AF on 22nd and 23rd continued to mark a poor autumn for this species locally.

A fast-moving Atlantic depression crossed northern Britain at the beginning of the week, bringing strong southwesterlies to western Britain, although these had lost impetus by the time they reached the Midlands. Otherwise the largely westerly airflow continued and the weather remained largely dry.

Coinciding with fresh Icelandic arrivals in northern Britain this week, thirty-one Pink-footed Geese flew high west over Pitsford Res on 18th while 20th saw the return to the Nene Valley of ‘Wossy’, last month’s escaped Ross’s Goose – this time at Clifford Hill GP.

Although with rather better credentials, another species which consistently receives short shrift from birders in the UK is Ruddy Shelduck and last week’s female remained south of the causeway at Pitsford Res all week; more on this later.

Two Pintails at Summer Leys LNR on 14th were the only ones this week, the same site hosting a Garganey throughout the period, although seven were there on 14th, one also visiting Clifford Hill GP the same day. A Goldeneye was found at Stanford Res also on 14th while the long-staying bird at Pitsford Res remained all week.

Raptors were in short supply with single Merlins at Raunds on 13th-14th, Pitsford Res on 16th and at Harrington Res the following day while a female Peregrine was at Blueberry Farm, Maidwell on 15th, 16th and 19th and a juvenile visited Stanwick GP on the last of these dates.

Wader passage was lifted somewhat this week. Single Little Ringed Plovers visited Clifford Hill GP and Hollowell Res on 14th, the latter site along with nearby Stanford Res also hosting a Ringed Plover on the same date. At least three were at Clifford Hill GP – also on 14th with some still there on 16th when three were also at Summer Leys, increasing to five there on 20th.

A Golden Plover was seen at Harrington AF on 14th and fourteen flew over nearby Blueberry Farm, Maidwell on 18th. Wader of the week was the juvenile Curlew Sandpiper which appeared during drizzly conditions at Clifford Hill GP on 14th but there have still been no Little Stints so far this autumn and time is surely running out …

Up to seven Dunlins were present at Clifford Hill GP between 14th and 20th while singes visited Summer Leys on 16th and Stanwick GP the following day but only Ruff this week were two near the dam at Pitsford Res on 14th and 15th and one at Summer Leys on 14th.

Two juvenile Black-tailed Godwits visited the latter locality on 20th. Common Sandpipers were found at five localities with two at Boddington Res and one at Hollowell Res on 14th, three or four at Pitsford Res on 16th and singles at Welford Res and Ditchford GP on 20th. Green Sandpiper numbers remained low with two at Pitsford Res on 14th, one there on 17th and one at Ditchford GP on 20th, while a late Wood Sandpiper was discovered on the drained lake at Wicksteed Park on 19th. 13th with two there on 10th and one at Stanwick GP on 12th. The only Greenshanks during the period were at Pitsford Res, where there were up to two between 14th and 18th. There have been no American waders in the county so far this autumn but we are now approaching the last week of September, which has a great track record locally for producing the goods, so fingers crossed!

A first-winter Mediterranean Gull was found in the gull roost at Pitsford on 16th with five Yellow-legged Gulls there on 18th. Other Yellow-legged Gulls included singles at Hollowell Res on 14th and at Ditchford GP on 20th while seven were at Stanwick GP on 19th. With all the local breeding Common Terns now departed two were found at Hollowell Res on 14th along with a juvenile Arctic Tern.

Away from the wetlands, a Short-eared Owl was at Blueberry Farm, Maidwell on 14th and two were present there on 18th while a Common Redstart was found at nearby Harrington AF on the first of these two dates. Whinchat were rather more widespread this week with singles at Boddington Res and Borough Hill on 14th and Sywell CP on 16th, up to two at Pitsford Res between 14th and 18th and up to eight at Blueberry Farm, Maidwell between 14th and 19th. A single Northern Wheatear at Harrington AF on 14th-15th continued to mark a poor autumn for this species locally but a flock of approximately fifty Yellow Wagtails at Chelveston Airfield on 20th was a good local record for this species.

Average temperatures and a predominantly westerly airstream followed colder northerlies prior to the beginning of the period. While winter duck numbers were slowly on the rise, few new migrants were discovered locally but …

Early autumn normally produces a scattering of Ruddy Shelducks in the UK and one was found south of the causeway at Pitsford Res on 12th. This coincided with others in East Yorkshire, Essex, Gloucestershire, Hertfordshire, Kent and Sussex. They are likely to be from the summer moult gathering in The Netherlands and the origin of these birds is uncertain.  An eclipse drake Pintail was at Summer Leys LNR on 8th with two there and three at Pitsford Res on 13th, the former site hosting a Garganey on 7th-9th and five on 13th while Pitsford Res continued to hold a two Red-crested Pochards and a Goldeneye from 7th to at least 10th. A ‘female-type’ Common Scoter on the easternmost pit at Stanwick GP on 12th formed part of an inland ‘mini influx’ at the time.

A Bittern showed well for over an hour on the recently reprofiled scrape at Summer Leys LNR on the morning of 8th and was seen again in flight there later in the day.

The long-staying Marsh Harrier continued to be seen in the Blueberry Farm area until at least 8th and again at nearby Harrington AF on 10th while another was over fields near Fotheringhay on 8th. An Osprey was again at Blueberry Farm on 7th and 9th, it or another visited Pitsford Res on 8th, the same day as one was tracked as it flew southwest over Stanwick GP and shortly afterward over Ditchford GP, while a male Merlin in the Brampton Valley on 9th was the first of the autumn/winter period.

Few new waders made landfall in the County this week. Two Little Ringed Plovers visited Hollowell Res and one was at Clifford Hill GP on 13th, where eight Ringed Plovers on 8th had dwindled to five by 12th and one on 13th, while one visited Stanwick GP on 9th and two were at Pitsford Res the following day. Two Golden Plovers were at Stanwick GP on 12th-13th. Up to three Dunlins were present at Summer Leys between 7th and 9th with one there on 13th but the only other site to host this species was Clifford Hill GP, which held six from 8th until 12th and 8 on 13th. Two Ruffs were at Pitsford Res on 10th with one there on 12th, another was at Summer Leys on 13th and nine Curlews visited Stanwick GP briefly on 11th, while 3 Common Sandpipers were found at Pitsford Res on 7th, with four or five there on 10th, Welford Res (two), Sulby Res (one) and nearby Naseby Res (one) – all on 7th – two were at Clifford Hill GP and one at Hollowell Res on 13th and, at Stanwick GP, there were two on 9th and three the following day. Green Sandpiper numbers were very low with three at Sulby Res on 7th, one at Pitsford Res on 8th and 13th with two there on 10th and one at Stanwick GP on 12th. The only Greenshanks during the period were at Pitsford Res, where there were up to three between 7th and 12th and eight Yellow-legged Gulls at Stanwick GP on 10th and one at Pitsford Res on 13th were also the only ones reported.

A Common Swift at Stanwick GP on 9th may have been the last one of the year, while a Whinchat was at Pitsford Res on 13th and up to six remained at Blueberry Farm,

Maidwell all week, the same site hosting up to two Northern Wheatears between 8th and 12th. A Tree Pipit was found at Pitsford Res on 10th and four Crossbills flew over Stanwick GP on the same date.

There was a westerly airflow throughout the week accompanied by unusually high temperatues (high twenties) and mainly clear skies toward the week’s end. This quickly changed, dropping suddenly by ten degrees on 6th as a result of an area of low pressure, which produced easterlies off southern Scandinavia, northerlies down the North Sea and rain and cloud stretching to the near continent … but nothing new in Northants.

More Pintail arrived this week with singles on 3rd at both Stanwick GP and Summer Leys LNR with the latter site producing a Garganey on the same date. Pitsford Res continued to host a Goldeneye and two Red-crested Pochards throughout the week as well as a short-staying Black-necked Grebe on 1st only.

The long-staying Marsh Harrier continued to be seen throughout the period at Harrington AF and in the nearby Brampton Valley/Blueberry Farm area while a juvenile flew east at Hollowell Res on 6th, an Osprey flew south there on the same date and another was in the Harrington AF/Blueberry Farm area on 31st and 3rd, while a Peregrine visited Pitsford Res on 2nd.

The lack of suitable habitat meant that the week did not yield an increase in the number of waders. The only Little Ringed Plovers were singles at Stanwick GP on 3rd and 6th and two at Hollowell Res on the same dates and the only Ringed Plovers were singles at Pitsford Res on 1st with two there on 6th, Welford Res on 2nd and at Clifford Hill GP on 6th with five there on 2nd. A Golden Plover visited Stanwick GP on 5th and another flew over Harrington AF on 6th and four Dunlin were at Hollowell Res on 2nd while twos visited Clifford Hill GP on the same date, Summer Leys the following day, Stanwick GP on 5th and two flew south-west at Clifford Hill GP on 6th with one also at Pitsford Res on the same date.

Juvenile Dunlin, Hollowell Res, 2nd September 2013 (Mike Alibone). Part of a group of four which dropped in to feed late in the morning. Once the commonest small wader in Northants and a regular winter visitor, Dunlin is now a passage migrant in small numbers in both spring and autumn. Long gone are the days when wintering flocks in excess of two hundred individuals were to be found at Pitsford Reservoir, building up while large areas of mud were exposed in autumn and remaining until rising water levels forced them to find alternative feeding habitat elsewhere later in the winter.

In contrast to last week just two Ruff were found – at Pitsford Res on 4th and at Earls Barton GP on 6th. Four Black-tailed Godwits visited Summer Leys on 2nd with one there the next day and just one Whimbrel was seen flying over at Harrington AF on 5th. Common Sandpipers were found at Welford Res, where there were two on 31st and four on 2nd, Pitsford Res, where there were three on 1st-2nd and four on 4th and at Stanwick GP with two on 3rd and one on 5th-6th, while the only Green Sandpipers were seen on 2nd – when three were at Sulby Res and one visited Foxholes Fisheries, Crick – and 6th, when one was at Pitsford Res. The only Greenshanks during the period were at Pitsford Res, where there was one on 2nd and two on 4th and 6th.

Rare gulls were few and far between with a juvenile Caspian Gull briefly at Daventry CP on 3rd being the only candidate this week, while a juvenile Mediterranean Gull visited Hollowell Res on 6th an adult Yellow-legged Gull was there on 31st and 6th and three were at Pitsford Res on 1st.

Of the more interesting passerine migrants, a juvenile Ring Ouzel was located at Harrington AF on 31st (remaining until the next day) when there was also one or two Common Redstarts, a Northern Wheatear and a Whinchat there, while four of the latter species remained at Blueberry Farm, Maidwell all week, the number at this site increasing to eight on 5th-6th. Finally, approximately twenty Crossbills were found in Salcey Forest on 2nd.

A strong easterly element to the wind direction in the early part of the week resulted in a busy time for local birders with 24th seeing a significant arrival of new birds.

The first Wigeon of the autumn arrived this week and double-figure counts came from several localities with the maximum being seventeen at Stanwick GP on 27th. Similarly, the autumn’s first Pintail appeared at Summer Leys LNR on 28th with six dropping in briefly to rest on ‘the slips’ there before continuing south and another remaining until 30th.

Eclipse drake Pintail, Summer Leys LNR, 28th August 2013 (Mike Alibone)

The same site produced a Garganey on 24th and further singles were found at Stanwick GP on 27th and at Pitsford Res the following day. More Red-crested Pochards arrived with four at Stanford Res on 24th, two at Summer Leys on the same date and two at Pitsford Res all week, while the long-staying eclipse drake remained at Stanwick GP throughout the period. A Goldeneye also remained at Pitsford Res all week and a Black-necked Grebe was found on the main lake at Stanwick GP on 27th before quickly moving on.

It’s proving to be a good autumn for Marsh Harriers with long-staying birds (or possibly the same individual) at Harrington AF until 25th and in the nearby Brampton Valley/Blueberry Farm area until 29th, along with singles at Stanwick GP on 24th and Summer Leys on 27th. An Osprey visited Pitsford Res regularly between 24th and 29th and a Peregrine was seen again at Stanwick GP on 25th.

Wader passage was brisk at the start of the week. The only Little Ringed Plover was one at Stanwick GP on 29th but more Ringed Plovers appeared with a juvenile at Summer Leys from 24th to 28th and six at Clifford Hill GP on 25th with three there the following day. Two Grey Plovers were on ‘the slips’ at Summer Leys fleetingly on 24th and four Dunlin were at Stanwick GP on the same date with two remaining on 25th and 26th, dwindling to just one on 27th. The same site produced good numbers of Ruff again on 24th, with a flock of twenty juveniles on the islands in the A45 Lay-by Pit, another by the visitor centre, and nine flying west while four were at Pitsford Res and one at Hollowell Res on the same date and three appeared at Summer Leys the following day with one remaining until 28th. Single Black-tailed Godwits were at Summer Leys from 24th to 26th and at Stanwick GP on 27th and 29th, while two were found south of the causeway at Pitsford Res on the latter date and five visited Summer Leys on 30th. Other large waders included two Whimbrels flying west at Stanwick GP on 25th and a Curlew on the ground at Clifford Hill GP the following day. Common Sandpipers were found in slightly higher numbers than last week at Pitsford Res, Naseby Res, Hollowell Res, Sulby Res and Stanwick GP with a maximum of five at Sulby Res on 30th. Four Green Sandpipers were at Summer Leys on 24th-25th with just one remaining the following day, two were at Slby Res on 30th and singles were at Stanwick GP on 24th and 29th while up to three Greenshanks were at Pitsford Res between 24th and 29th, two were at Sulby Res on 30th and singles visited Stanwick GP on 25th and 27th. The latter site hosted the week’s only Redshanks with just two there on 29th; this species is proving to be scarce this autumn. A Turnstone also visited Stanwick GP on 24th.

A juvenile Mediterranean Gull was in the gull roost off the yacht club at Pitsford Res on 24th, being joined by a second juvenile there the following evening and one was there again on 30th. Last week’s juvenile Caspian Gull was again at Stanwick GP on 24th and another was at Pitsford Res gull roost on 30th. The same two sites continued to produce Yellow-legged Gulls throughout the week with maxima of ten at Pitsford on 24th and approximately twenty-five at Stanwick on 29th. A juvenile Little Gull also visited the latter site very briefly on 24th and was joined equally briefly by two juvenile Arctic Terns there at the same time. The 24th also proved to be a great day for Black Terns with forty-five on Thrapston GP’s Town Lake providing a wonderful early evening spectacle. Six visited Summer Leys on the same date and four were there the following day along with two at Welford Res and one at Pitsford Res.

A Short-eared Owl was reported by the landowners at Blueberry Farm, Maidwell on 24th and another was found at Harrington AF on 30th when a juvenile Ring Ouzel was also found at the same site. Blueberry Farm hosted a Common Redstart on 29th while others appeared at Pitsford Res on 24th, Harrington AF and Spratton on 25th and a male was in Denton Wood

on 28th and 29th. Up to six Whinchats were at Blueberry Farm throughout the week and a Northern Wheatear was there on 29th with another at nearby Harrington AF on 28th. A Tree Pipit flew east over Stanford Res on 24th and another south over Brackley on 28th while flyover Crossbills consisted of five over Stanwick GP on 24th and two over Hanging Houghton on 27th.

A warm southerly airstream ensured continued warm weather throughout the week and may have contributed to the appearance of a species not seen in Northamptonshire for at least one hundred and thirty years …

Two Egyptian Geese were at Ditchford GP on 23rd, the escaped Ross’s Goose was again with Greylags at Stanwick GP on 17th and a Garganey appeared at Pitsford Res on 22nd. The long-staying eclipse drake Red-crested Pochard lingered at Stanwick GP all week with another briefly visiting Summer Leys LNR on 20th and two females at Pitsford Res on 23rd and a Goldeneye was again at Pitsford Res on 22nd-23rd. A Great White Egret was again at the latter locality on 17th.

One of last week’s Marsh Harriers remained at Harrington AF, being seen daily until 23rd while it, or another, visited nearby at Blueberry Farm, Maidwell on 18th and another flew west over Boddington Res on 21st and a juvenile was seen at Ditchford GP on 23rd. Single Ospreys were seen at Pitsford Res on 17th and 22nd, over Blueberry Farm on 18th, over Harrington AF on 20th and over both Hanging Houghton and Quinton the following day. A juvenile Peregrine was observed taking a Lapwing at Stanwick GP on 17th and another was at Twywell Hills and Dales on 23rd.

Two juvenile Little Ringed Plovers were at at Summer Leys until at least 17th, two were at Stanwick GP on 22nd-23rd and one at Earls Barton GP on 23rd. The only Ringed Plover this week was one at Pitsford Res on 17th, while Summer Leys produced a Dunlin on the same date and small numbers were at Stanwick GP all week, peaking at seven on 21st. The same site held a juvenile Ruff on 21st-23rd. Adult Black-tailed Godwits were still moving through, with two at Summer Leys on 19th, one there on 23rd and four over Daventry CP on 22nd, although Common Sandpipers were strangely scarce this week with just two at Pitsford Res on 17th and 22nd, with singles at Daventry CP and Stanwick GP on the latter date and one at Earls Barton GP on 23rd. Green Sandpipers were a little more numerous, however, with singles at Pitsford Res on 17th and 20th-22nd and at Summer Leys and Ditchford GP on 23rd, seven at Daventry CP on 19th with five there on 22nd and two at Stanwick GP on 20th with three there on 21st. Summer Leys continued to hold on to its Greenshanks with three still there on 17th, two on 19th and one on 23rd and further records of singles came from Stanwick GP on 20th, Pitsford Res on 21st, Ditchford GP on 23rd and Clifford Hill GP on 22nd, with three at the latter site on 23rd.

A juvenile Mediterranean Gull was found at Daventry CP on 21st and two juveniles visited the gull roost at Pitsford Res the following evening, while two Caspian Gulls – an adult and a juvenile were discovered with Yellow-legged Gulls at Stanwick GP on 21st.

Numbers of the latter continued to remain relatively high at this locality with a maximum of approximately thirty on 21st and, elsewhere, singles were at Pitsford Res on 20th-21st and Clifford Hill GP on 22nd with four at Pitsford Res on 22nd and seven at Clifford Hill GP on 23rd.

Few would dispute that the ‘Bird of the Century’ title should surely go to the juvenile Woodchat Shrike which was found at Harrington AF on 20th. Showing well to all comers during the afternoon, this was the first to be seen in Northants for at least 130 years but it did not linger, much to the disappointment of early morning birders the following day. One was also seen at Gibraltar Point, Lincolnshire on 17th and it is tempting to speculate that this was the same bird moving south.

A Common Redstart was found near the river at Woodford Halse on 20th, two more were at Harrington AF on 23rd and one was at Ditchford GP on 23rd, while a Stonechat was in the Brampton Valley/Blueberry Farm, Maidwell area on 21st and up to four Whinchats were in the same area between 17th and 22nd, with two more at Ditchford GP on 23rd. Northern Wheatears were found in the Brampton Valley on 17th and 21st and one visited Clifford Hill GP on 18th, while Tree Pipits flew over Harrington AF and Hanging Houghton on 18th.  Migrant Crossbills continued to be seen, with two over Hanging Houghton on 18th and six over Harrington AF on 18th and 22nd.

Mixed weather conditions combined with a largely westerly airstream to produce little in the way of new birds this week.

A Ross’s Goose was discovered at Stanwick GP on 11th and was still present there on 13th. Although this species is one of the earliest geese to depart from its Arctic breeding grounds in autumn, an early to mid-August arrival in the UK is not likely so, undoubtedly of captive origin, it falls into the category of ‘scarce escape’ compared to the normal, run of the mill, fence-hopping wildfowl we are used to seeing locally.

A Garganey, the credentials of which were never in dispute, was also at Stanwick GP on 12th-13th as was last week’s eclipse drake Red-crested Pochard while a Goldeneye was found at Pitsford Res on the first of these two dates and remained until 15th.

An early autumn Bittern put in a brief appearance on the edge of the reeds on the scrape at Summer Leys LNR on 13th and was also seen there again on 16th.

Up to two Marsh Harriers frequented Harrington AF between 11th and 16th, while, on 15th, two were at Blueberry Farm, Maidwell and one flew west over Weedon on 16th. Single Ospreys were seen daily at Blueberry Farm between 10th and 13th and one was at Pitsford Res on 14th-15th and the only Peregrine of the week was a juvenile at Stanwick GP on 10th.

Two juvenile Little Ringed Plovers were at at Summer Leys until at least 11th with a juvenile Ringed Plover there on the same date and again on 16th. Two more Little Ringeds and a Dunlin were at Stanwick GP on 14th, another Dunlin visited Summer Leys on 16th and two juvenile Curlew Sandpipers were reported from Stanwick GP on 13th, where there was also a Ruff on the same, and the following, date with two at Daventry CP on 16th. Larger waders included eleven Black-tailed Godwits at Stanwick GP on 12th, a Whimbrel there on the following day and a Curlew in flight over Harrington AF on 16th. Common Sandpipers were recorded from Summer Leys, Bozeat GP, Ditchford GP, Earls Barton GP, Stanwick GP, Pitsford Res and Sywell CP with no more than two at any one location, while Green Sandpipers were found at Bozeat GP, Ditchford GP, Stanwick GP and Daventry CP with a maximum of five at the latter site on 16th. The only Greenshanks recorded this week were up to three at Summer Leys, two at adjacent Earls Barton GP on 11th and two at Stanwick GP on 14th.

Yellow-legged Gulls numbers remained high at Stanwick GP throughout the week with a maximum of forty-four – a new record high count for Northants – on 10th and one also visited Daventry CP on 16th, the same site also hosting a juvenile Mediterranean Gull on 13th.

Harrington Airfield produced single Common Redstarts on 11th, 12th, and 16th and another was in the Brampton Valley below Hanging Houghton on the latter date while two Whinchats were at the former locality on 11th and up to six remained at Blueberry Farm, Maidwell all week. The autumn’s first Northern Wheatears were found at Byfield on 14th and at Cransley Res two days later and a Tree Pipit – now a scarce migrant in Northants – flew over Harrington AF on 12th.  Migrant Crossbills continued to be seen, with two singles flying south-west over Harrington AF on 10th, three flying east over Stanwick GP on 13th and two again over Harrington AF on 15th.

After a prolonged period of summer heat, temperatures returned to near normal this week in an almost continuous south-westerly airstream, which also brought heavy rain on 5th. Autumn migration began to gather pace.

The eclipse drake Red-crested Pochard remained at Stanwick GP until at least 8th as did the Great White Egret at Clifford Hill GP, with another reported at Pitsford Res on 6th and 7th. A juvenile Marsh Harrier appeared in at Blueberry Farm, Maidwell on 5th and may well have been the same individual seen at Harrington AF on 8th and 9th but the only other raptor of note was an Osprey at Welford Res on 7th. 

Up to four Little Ringed Plovers remained at Summer Leys LNR until at least 7th, while four Dunlin – the only record this week – visited Clifford Hill GP on 3rd and a juvenile Ruff appeared at Summer Leys on 6th. The only Black-tailed Godwit this week was one at Stanwick GP on 8th, while Common Sandpipers were recorded from the latter locality, Summer Leys and Pitsford Res and single Green Sandpipers visited Pitsford Res and Summer Leys on 6th and two were at Daventry CP the following day. Up to five Greenshanks lingered at Summer Leys between 3rd and 7th, one was at Clifford Hill on 6th with seven there on 8th and three visited Stanwick GP on the same date, while the first Turnstone of the autumn was mobile around the yacht club at Pitsford Res on 9th.

Good numbers of Yellow-legged Gulls remained at Stanwick GP throughout the week with maxima of thirty plus on 5th and seventeen there on 8th; elsewhere single adults

were at Pitsford Res on 3rd, 4th, 8th and 9th with six there in the gull roost on 7th and two at Clifford Hill GP on the same date. An adult Mediterranean Gull was also at Stanwick GP on 5th and a second-summer visited Daventry CP on 7th. Single Common Redstarts were found at Blueberry Farm, Maidwell on 3rd and at Harrington AF on 8th and also Whinchats visited both these localities with, at the former locality, four on 7th and 3 on 9th and two at the latter on 8th when two were also found in the Brampton Valley below Hanging Houghton.  Two Crossbills were near the entrance to Harlestone Heath on 6th and two flew north-west over Harrington AF the following day.

Temperatures remained relatively high and heavy showers hit the County on 27th and 29th, causing water levels to rise slightly at local bodies of water. With migration now well under way, a number of interesting visitors were discovered as the week progressed.

Last week’s eclipse drake Mandarin Duck was still at Ravensthorpe Res on 29th and single summering drake Wigeon remained at nearby Hollowell Res and at Clifford Hill GP on the same date with four at Summer Leys LNR on 28th.  The eclipse drake Red-crested Pochard remained at Stanwick GP also until 29th and a Goldeneye was found at Pitsford Res the following day.

In what has turned out to be a very poor summer for Quail one – the second only this year – was singing near Ashton Wold on 27th. By contrast, however, in a good year for Great White Egrets, one was found at Clifford Hill GP on 27th and remained there all week, frequenting the grassy peninsular at the western end of the main barrage lake.

Another ‘Black Kite’ was reported, this time drifting over the A14 near Cranford St John on 28th and the only other notable raptors were an Osprey in the Brampton Valley below Hanging Houghton on 29th and a Peregrine at Summer Leys on 28th.

Little Ringed Plovers were recorded at Summer Leys, where up to four remained all week, while four Dunlin were also at Summer Leys on 27th with singles there on 30th and 2nd, one was at Pitsford Res on 28th and six at Clifford Hill GP on 31st. Summer Leys produced the only Black-tailed Godwits of the week with nine on 27th-28th and five on 2nd, a Whimbrel went through at Stanwick GP on 30th, while Common Sandpipers were recorded from Clifford Hill GP, Stanwick GP, Summer Leys, Hollowell Res and Pitsford Res, with a maximum of three or four at the latter site on 30th and four at Summer Leys the following day. In contrast to last week, only two Green Sandpipers were found, with singles at Summer Leys and Stanwick GP on 31st and one again at Summer Leys on 2nd and a single Greenshank remained at Summer Leys from 30th until the week’s end, the same locality producing the autumn’s first Wood Sandpipers with up to two there intermittently between 29th and 2nd.

The late summer build-up of Yellow-legged Gulls continued with daily records from Stanwick GP, where there was a maximum of thirty-five on 30th, one was at Clifford Hill GP and four or five were at Pitsford Res on the same date with one there the following day. An adult Caspian Gull also visited Stanwick GP on 30th and the same site hosted an adult and a juvenile Mediterranean Gull on 29th, the juvenile remaining until 1st.

Passerine migrants were in short supply this week with just a Common Redstart along the old railway line at Summer Leys on 31st, a Whinchat at Blueberry Farm, Maidwell on 2nd and two small parties of Crossbills totalling at least nine individuals flying south-west over Pitsford Res on 27th with four more over Bucknell Wood on 1st.
