Category: Weekly Reports

Bolstered by winds from the south-west and again largely dry, the unseasonally mild weather continued throughout the week, with this month on course to enter the record books as the mildest December for seventy years, if not the mildest ever.

Three Bewick’s Swans flew west over Blueberry Farm, Maidwell on 12th and two – which appeared to be a pair – arrived in Scaldwell Bay at Pitsford Res, four days later, on 16th. In decline, it is now a rare visitor to the county, with wintering flocks regularly exceeding sixty at this site in the 1970s now sadly consigned to history. An exciting new conservation initiative for this species will be announced by the Wildfowl & Wetlands Trust next week.

The Pitsford Ruddy Shelduck was still present on 16th and same site held six Pintails on the same date. Stanford Res again produced the week’s only Red-crested Pochard – a male on 13th, with the first-winter Scaup still present on the same date, and Pitsford Res’s drake Smew still on site on 14th.

After two uncharacteristically short-stayers, it would have been surprising if the larger part of the winter had passed by diverless so the discovery of another juvenile Great Northern at Ditchford GP on 13th was welcomed, if not entirely unexpected, as it remained throughout the week.

Also remaining were up to two Great White Egrets at Pitsford Res, one at Ravensthorpe Res and another in the mid-Nene Valley, which visited Wellingborough on 14th, Ditchford GP on 17th and Summer Leys LNR the following day. By comparison, Bittern is a ‘rarity’, with only one being seen at the regular wintering site of Stortons GP on 16th. The Red-necked Grebe, discovered at Pitsford Res at the end of last week, appeared settled, remaining just off the dam, by the overflow, throughout. However, it has a long way to go to equal the length of stay of the second calendar year male Marsh Harrier which was still in the Summer Leys area at the end of the week. The only other raptors on the radar during the period were Peregrines at Ditchford GP on 13th, Daventry CP on 14th (two) and Higham Ferrers on 18th.

Golden Plovers counts this week were restricted to approximately five hundred between Pitsford Res and Sywell Airfield on 16th and the same number at Summer Leys two days later. The only Redshank was again one at Pitsford Res on 12th with three Green Sandpipers there on 16th and up to two at Ravensthorpe Res on 14th-18th. Two Common Snipes were also at Ravensthorpe Res on 15th and 18th and a Curlew visited Pitsford Res the following day.

This week’s rare larids were represented by adult Caspian Gulls at Stanford Res on 13th and Pitsford Res on 14th with a first-winter at Daventry CP the following day and the only Yellow-legged Gulls were single adults at Daventry CP and Ravensthorpe Res on 14th and 15th respectively.

Two Short-eared Owls remained into the week at Blueberry Farm, Maidwell while the bird in the set-aside area, east of the feeder stream at Stanford Res, continued to be reported almost daily and was joined by another there on 16th. Feeding on halved apples and fatballs, Central European Blackcaps visited gardens in Barton Seagrave, Corby, Sywell and Wellingborough, while a Siberian Chiffchaff was found with Chiffchaffs along the outfall stream at Ecton SF on 14th and the only Stonechats reported were two at Ditchford GP on 13th and one at Thrapston GP on 18th.

Strong south-westerly winds dominated the first two days of the period as ‘Storm Desmond’ dumped significant rain on northern Britain, leaving the Midlands relatively unscathed. The following five days saw sporadic rain and continuing above average temperatures, albeit lower than those of the previous week.

Three Pink-footed Geese flew east over Blueberry Farm, Maidwell on 5th; none has yet been found on the ground so far this winter. The Pitsford Ruddy Shelduck was seen twice – on 9th and 11th and the same site hosted up to four Pintails on 6th, while two were seen flying over Burton Latimer on 11th. Stanford Res produced the week’s only Red-crested Pochard – a female on 5th, along with last week’s first-winter Scaup, still present on the same date, and Pitsford Res’s drake Smew reappeared on 6th and was later joined by a ‘redhead’ from 9th.

Pitsford also continued to hold up to two – possibly three – mobile Great White Egrets throughout the period, while singles remained at Summer Leys LNR until at least 7th and at Ravensthorpe Res until 8th. The first in the county this year, a Red-necked Grebe just off the dam at Pitsford was a nice end of week find on 11th and will hopefully remain for birders to catch up with over the weekend.

Showing no signs of departing any time soon, the second calendar year male Marsh Harrier remained in the Summer Leys area until at least 9th but no other scarce raptors were reported during the week.

Approximately one thousand Golden Plovers at Ditchford GP’s Irthlingborough Lakes & Meadows LNR on 6th represents the best count for this species so far this autumn, while the only other record for the week was eleven at Pitsford Res. The only Redshanks were one at Pitsford Res on 6th and six at Stanwick GP on 8th, while up to two Green Sandpipers were Daventry CP on 5th, singles were at Ravensthorpe Res on 5th and 8th and two were at Pitsford Res on 6th. Twenty-one Common Snipe were counted at Pitsford Res on 6th and two were at Ravensthorpe Res on 8th.

Scarce gulls were few and far between this week and included a first-winter Mediterranean Gull at Daventry CP on 5th, adult Caspian Gulls again it the gull roost at Pitsford Res on 5th and 9th and another adult at Daventry CP on 10th and a Yellow-legged Gull at Stanwick GP on 8th.

Four localities produced this week’s Short-eared Owls which comprised singles at Stanford Res, Harrington AF and in the Brampton Valley on 7th plus one at Stanwick GP the following day. Central European Blackcaps visited gardens in Maidwell on 6th, Wellingborough on 7th (two) and Duston, Northampton on 8th but of more interest was a Lesser Whitethroat – possibly of eastern origin – in a garden at Adstone on 11th. Two Stonechats remained at Blueberry Farm, two were nearby in the Brampton Valley and one was at Summer Leys on 8th-9th, while the only Bramblings reported were three at

Stanford Res on 5th and singles at Pitsford Res and Guilsborough on 6th and 10th respectively. Between seven and ten Crossbills were seen near the dam at Pitsford Res on 7th.

This week saw the official commencement of winter – at least in meteorological terms – although temperatures here and in northern Europe remained well above the seasonal norm, effectively delaying any new arrivals of wildfowl from the continent.

Ducking and diving, the Pitsford Ruddy Shelduck reappeared in field south of the causeway on 2nd; it has not been easy to keep track of this autumn.

The only Pintails were three at Earls Barton GP on 28th and the same date saw three Red-crested Pochards at Stanford Res, dropping to one by 3rd and four were at Pitsford Res on 30th with five there on 4th, while last week’s first-winter Scaup remained at Ravensthorpe Res until 28th, before moving to Stanford Res on 4th.

The following day produced a Bittern at Stanford Res and the count of Great White Egrets at Pitsford Res fell to just one between 28th and 30th although two were there on 4th, while singles remained throughout the week at Ravensthorpe Res and Summer Leys LNR.

At the latter site the second calendar year male Marsh Harrier made it into December, still being present there on 3rd but the only Peregrine reported was one at Blueberry Farm, Maidwell on 2nd and a Merlin flew west at Stanwick GP on 4th.

Golden Plover numbers were up on last week’s, however, with records from Clifford Hill GP, Daventry CP, Harrington AF, Milton Malsor, Summer Leys LNR and Stanwick GP with the latter site producing the maximum count of six hundred on 30th, 3rd and 4th. The only Redshanks were one at Pitsford Res and three at Stanwick GP on 30th and five at the latter locality on the following day, while four Green Sandpipers were at Broadholme STW (Ditchford GP) on 28th, with singles at Ecton SF and Ravensthorpe Res on the same date and at Pitsford Res on 30th, with two again at Ravensthorpe Res on 1st and 4th, where a Common Snipe was present on the same dates and one was at Hollowell Res on 4th.

Scarce gulls were more in evidence this week with a second-winter Mediterranean Gull at Daventry CP on 30th followed by an adult (complete with green ring on left leg) there on 2nd and an adult Caspian Gull was present it the gull roost at Pitsford Res on 28th-29th, another adult was at Stanford Res on 4th, while a second-winter visited Stanwick GP on 1st-3rd and a first-winter was there on 2nd. Up to two Yellow-legged Gulls were reported from Daventry CP, Hollowell Res, Stanford Res and Stanwick GP with the latter locality producing an adult Glaucous Gull on the Visitor Centre Pit on 3rd, while a fly-over adult ‘white-winged’ gull there the following evening was almost certainly the same individual.

One or two Short-eared Owls were discovered in fields immediately north of the church at Long Buckby on 1st and one remained around the southernmost field of the Blueberry Farm complex until at least 2nd.  Wintering Central European Blackcaps visited gardens in Barton Seagrave on 28th and Scaldwell on 1st and another Siberian Chiffchaff was discovered – this time at Stanwick GP – on 30th, being seen there again on 1st.

Four Stonechats remained at Blueberry Farm until at least 2nd, the same  number was at Hollowell Res on 1st and one remained at Summer Leys all week, while the only Bramblings reported were four at Hanging Houghton on 30th and one over Harrington AF on 2nd.

Largely dry conditions prevailed although a strong, northerly airstream was in place on 21st, temporarily displacing the hitherto mild autumn weather and delivering the first local frost of the autumn on 22nd.

A herd of fourteen Whooper Swans flying north over Warmington on 21st was perhaps unsurprising as this village is close to the border with Cambridgeshire where this species regularly winters. At least two Pintails were still at Earls Barton GP on 25th and the same number of Red-crested Pochards at Pitsford Res on 22nd, when there was also a female Scaup there, followed by a first-winter Scaup at Ravensthorpe Res on 24th.

Back at Pitsford, the first Smew of the winter – a drake – was found north of the causeway on 23rd, the same site also continuing to host up to four Great White Egrets. Single Great Whites remained at Ravensthorpe Res until at least 25th and at Summer Leys LNR all week.

The second calendar year male Marsh Harrier continued its regular visits to the latter site until 25th, while other scarce raptors included single Merlins at Blueberry Farm, Maidwell on 22nd and Ravensthorpe Res on 24th and two – possibly three – Peregrines visited Fawsley Park on 25th, attracted to the large Starling roost which is currently building there.

Waders were thin on the ground this week with Golden Plovers reported only from Harrington AF, where there were approximately twenty-five on 21st and sixty-three on 25th while the only Dunlins were singles at Pitsford Res on 22nd and Daventry CP the following day. Pitsford produced the only Redshank, one on 22nd, and one of two Green Sandpipers on the same date, while the other was at Ravensthorpe Res on 25th.  The only Common Snipe were seven at Daventry CP on 23rd and three at Pitsford Res on the same date.

Hot on the heels of the two at Stanford Res last week, a first-winter Kittiwake appeared at Earls Barton GP during the northerly gales of 21st and an adult Mediterranean Gull visited Daventry CP on 23rd. Single Yellow-legged Gulls at Stanford Res on 21st and Daventry CP on 23rd represented the lowest number reported in a long time.

Up to two Short-eared Owls remained at Blueberry Farm until at least 22nd and another was near Little Harrowden on the same date but it is not (yet) looking good for a big shortie winter.

Although there have been several around during late autumn, it would now surely be safe to say that single males visiting gardens in Greens Norton on 23rd and Northampton on 25th are Central European Blackcaps which are set to overwinter. How long will it be before they are granted full subspecific status? Another warbler still climbing the ladder to specific rank is Siberian Chiffchaff, two of which were identified this week – one at Ravensthorpe Res on 24th and the other at Pitsford Res the following day, the latter individual likely to have been present since 20th.

Up to ten Stonechats remained at Blueberry Farm and two further singles were at Ditchford GP on 22nd and Summer Leys from 24th to 27th. The only Brambling reported was one at Kelmarsh on 22nd.

The mild weather of the previous two weeks continued unabated as west to south-westerly winds helped to maintain unseasonally high temperatures, while also producing storm-force winds halfway through the review period.

The first Pink-footed Geese of the winter appeared on 20th, when five flew over Blueberry Farm, Maidwell. Having last been seen on 3rd, the Pitsford Ruddy Shelduck was again present on 17th, while up to five Pintails remained in the Summer Leys/Earls Barton GP area between 7th and 19th, one was still at Ravensthorpe Res on 9th and six at Pitsford Res on 20th.

The two Garganeys remained, with the first-winter female at Pitsford Res until 8th and the young drake at Ravensthorpe Res until the following day, while a glut of hybrid ducks included a drake Tufted Duck x Pochard hybrid (resembling a drake Lesser Scaup) at

Summer Leys LNR on 8th, a drake Gadwall x Eurasian Wigeon hybrid at Stanwick GP on 9th and a drake Chiloe Wigeon x Eurasian Wigeon hybrid (resembling a drake American Wigeon) at Earls Barton GP on 14th-15th. Seven Red-crested Pochards visited Summer Leys on 7th, while four were at Stanford Res on the same date and three there on 18th, while five remained at Pitsford Res between 9th and 12th, rising to thirteen there on 20th.

An adult Great Northern Diver which made a surprise visit to Stanwick GP on 11th was the first record for the site but it had departed by the following day. It would seem likely, then, that one found not too far away on Mary’s Lake at Earls Barton GP, just two days later, was the same individual. Amazingly, however, the latter proved to be a juvenile which stayed until the morning of 14th before departing south.

In the same general area, the Summer Leys Bittern showed itself again on, or over, the scrape on 7th, 18th, 19th and 20th the same site also hosting a Great White Egret on 14th and 19th-20th, while another remained at Ravensthorpe Res between 16th and 19th. Pitsford Res also held up to four throughout the period and one visited Ditchford GP on 15th.

The second calendar year male Marsh Harrier, present at Summer Leys LNR since at least mid-October, remained throughout the period, while Peregrines were also seen here as well as at Higham Ferrers, Pitsford Res, Blueberry Farm and in the Brampton Valley. At least five Merlins were seen and included singles at Harrington AF, Pitsford Res and Stanford Res on 7th, Blueberry Farm Maidwell on 9th and 17th, Stortons GP on 15th and near Chapel Brampton on 20th.

There were fewer Golden Plovers reported during the period with just over one hundred at Thrapston GP on 9th, at least twenty-five over Blueberry Farm on the same date, thirty-five between Moulton and Holcot on 20th and two at Pitsford Res on the same date. The only Common Snipe reported were eight at Earls Baron GP and one at Moulton Quarry – both on 15th – and forty-eight at Pitsford Res on 20th, where a Jack Snipe was also present at the same time. Other waders included a Curlew over Summer Leys on 19th, a Redshank at Pitsford Res between 14th and 20th and two Green Sandpipers at both Daventry CP on 7th and Ravensthorpe Res on 7th-9th, with one at Pitsford Res on 8th and four there on 20th.

November is often a good month for the appearance inland of Kittiwakes and this one was no exception with two adults turning up at Stanford Res on the afternoon of 20th. An adult Mediterranean Gull also visited the same site on 16th, a first-winter was in the roost at Boddington Res on 10th and another adult appeared at Pitsford Res the following day. There were just two Caspian Gulls during the period – a first-winter at Stanwick GP on 15th, followed by an adult at Stanford Res on 16th and 18th, while the usual small numbers of Yellow-legged Gulls continued to linger, these including up to two adults at Pitsford Res on 9th and 14th, one at Ravensthorpe Res and two at Hollowell Res on 9th, eight in the Boddington Res roost on 10th with one there on 18th and two at Stanwick GP on 15th.

Short-eared Owls are now becoming more regularly seen at Blueberry Farm where up to two have been present between 10th and 20th, while a late House Martin was seen flying over the A509 on the county boundary near Warrington on 9th. A male Black Redstart appeared in Kettering, north of the town centre, on 19th but appeared not to be

present the following day and, looking like they are set to winter in the area, the number of Stonechats at Blueberry Farm reached double figures with ten there on 9th and 20th. Smaller numbers elsewhere included four at Hollowell Res, two at Pitsford Res and two near Harlestone Heath.

Several Bramblings were noted at Scaldwell, Pitsford Res/Brixworth CP and Blueberry Farm, while single Crossbills were seen over Scaldwell on 8th and 16th and at Brixworth CP on 20th.

An unseasonally mild two weeks saw record-breaking November temperatures on 1st as winds persisted from a largely southerly direction throughout the period.

Aside from the Pitsford Ruddy Shelduck remaining until 3rd, a mixed bag of wildfowl included more Pintails, with singles at Daventry CP, Ravensthorpe Res, Stanwick GP, Summer Leys LNR and Wicksteed Park Lake plus six at Pitsford Res on 31st and four at Earls Barton GP on 5th.

Two Garganeys remained into November – the first-winter female at Pitsford Res on 3rd and the young drake at Ravensthorpe Res until at least 4th, while Daventry CP bowled a curved ball in the shape of a first-winter drake American Wigeon x Eurasian Wigeon hybrid on 28th and Pitsford delivered a Ferruginous Duck x Red-crested Pochard hybrid on 31st. ‘Real’ Red-crested Pochards included up to seven at Stanford Res between 25th and 1st, up to ten at Pitsford Res on 31st-1st, one at Stanwick GP on 4th and up to six at Daventry CP on 4th-5th.

A Bittern put in a brief appearance at Summer Leys LNR on 25th while up to five Great White Egrets remained at Pitsford Res throughout the period and one visited Stanford Res on 1st. Pitsford also produced a Slavonian Grebe on 30th-31st – only the third to be seen in the county this year.

The second calendar year male Marsh Harrier, present at Summer Leys LNR since at least mid-October, remained throughout, appearing with some regularity over the scrape, where it provided great photo opportunities for some. Peregrines were widespread this week with singles at Borough Hill, Brixworth CP, Ecton SF, Higham Ferrers, Stanwick GP and Summer Leys LNR, while twos were seen at both Ditchford GP and Hardingstone GP.

On the wader front, Golden Plovers were reported from Daventry CP, Harrington AF, Harringworth, Hollowell Res, Summer Leys LNR, Thorpe Waterville and Tiffield with the largest count of three hundred and four coming from Daventry CP on 26th.

A single Ringed Plover visited Pitsford Res on 30th, 2 Dunlin were at Stanwick GP on 4th and  Common Snipe were at six localities, with double-figure counts of fifteen at Ecton SF on 1st and twenty-three at Daventry CP on 6th. Green Sandpipers were found at Daventry CP, Ecton SF, Pitsford Res and Ravensthorpe Res with a maximum of three at the latter locality on 1st.

This week’s Mediterranean Gull was again a first-winter, this time in the roost at Pitsford Res on 24th, while single adult Caspian Gulls were Stanford Res on 25th and Daventry CP on 6th and a third-year visited Hollowell Res on 26th. The reservoirs of Boddington, Hollowell, Pitsford and Ravensthorpe all produced Yellow-legged Gulls as did Daventry CP with the latter site, along with Pitsford, producing the period’s maxima of four.

Just one Short-eared Owl was mobile around Harrington AF on 4th, while a seriously late Sand Martin was a surprise for one observer at Stanford Res on 1st – although it still has a long way to go to beat the latest record of a juvenile which remained around Islip SF from 17th to 22nd November 1976. Another Black Redstart was found during the period, at Wellingborough on 28th, while Stonechats continued to be seen in the Brampton Valley and at Hollowell Res, Pitsford Res, Summer Leys LNR and  Thrapston GP, with a maximum of six at Hollowell Res on 26th. Late October still continues to produce Rock Pipits and Hollowell Res held up to two on 26th-27th, while a Water Pipit flew south, calling, over Harrington AF on 4th. Small numbers of Bramblings were seen at Borough Hill, Catesby, Daventry CP, East Carlton CP, Pitsford Res, Woodford Halse and Harrington AF – the latter site producing the maximum of six on 3rd.

It was back to a week of westerlies, which also included one day of heavy rain. Migration, however, continued unabated with waves of winter thrushes, Skylarks and finches moving through the county along with a handful of new, scarcer arrivals.

Falling into the latter category – and part of a national movement – a Whooper Swan joined the Mutes at Blatherwycke Lake on 18th, while a Barnacle Goose was again at Clifford Hill GP on 20th and two were at Pitsford Res on 23rd. The latter site continued to host last week’s Ruddy Shelduck until 23rd, as well as producing the highest count of Pintails so far this autumn with twenty-four there on 23rd, while the drake remained at Wicksteed Park Lake on 20th, another visited Clifford Hill GP on the same date and one was at Daventry CP on 23rd. One juvenile Garganey remained into this week – the Ravensthorpe Res individual, which ultimately proved to be a male and was still present on 19th.

Up to thirteen Red-crested Pochards were at Pitsford Res on 21st, this location also continuing to host three Great White Egrets until 23rd, when five were counted north of the causeway – a record number for the site and equal to the county’s previous single site record at Summer Leys on 20th February this year. One also visited the latter site on 17th, followed there briefly on 20th by a first-winter Spoonbill, which had spent the previous three weeks at Eyebrook Res in Leicestershire.

Summer Leys also produced a Marsh Harrier between 17th and 19th, while a ‘ringtail’ Hen Harrier was seen at Harrington AF on the last of these dates. Single Merlins – or just one mobile individual – were in the Brampton Valley at Merry Tom crossing on 17th, near Brampton Halt on 18th and at Blueberry Farm on 18th-19th and Peregrines visited Harrington AF on 18th, Blueberry Farm on 19th-20th and Daventry CP on 23rd.

Numbers of Golden Plover ramped up this week with maximum site counts including three hundred at Thorpe Waterville on 18th, one hundred and sixty-five at Daventry CP on 23rd, one hundred and fifty at Harrington AF on 19th and thirty-four at Hartwell on 22nd. Other waders included two Ringed Plovers at Hollowell Res on 17th and 23rd, 2 Dunlin and three Common Snipe at Pitsford Res and 2 Common Snipe at Hollowell Res – all on 17th – and two Green Sandpipers at Ravensthorpe Res on 19th with three at Daventry CP on 23rd. Scarce larids included a first-winter Mediterranean Gull at Daventry CP and an adult Caspian Gull at Hollowell Res – both on 23rd and up to two adult Yellow-legged Gulls remaining at Pitsford Res and at Hollowell Res, while one was at Hartwell and three at Daventry CP on 22nd.

North Northants produced four Short-eared Owls – two each at Harrington AF and Blueberry Farm – all on 19th and the following day saw two Firecrests appear, one of which was a female trapped and ringed at Stanford Res and the other a male in a mobile tit flock at Hollowell Res. Another Black Redstart was found this week – one around ‘The Granary’ at Fawsley Park on 23rd, while a very late Whinchat was discovered at Stanwick GP on 20th, the same site also hosting up to two Stonechats on 20th-21st. More Stonechats included the regulars at Blueberry Farm, where up to three were present all week, two at Hollowell Res on 23rd and one at Harrington AF on 19th. As late autumn became even later more Bramblings were found this week and the quota included fourteen at Stanford Res on 17th, one at Polebrook AF on 18th, two at Harrington AF on 18th with eight there the following day, two at Blueberry Farm on 18th and 20th and at least four at Walgrave on the last of these dates. A Corn Bunting around the bunkers of Harrington AF on 18th would appear to be only the second record of this species in the county this year.

An established easterly airstream flowing from well beyond the Baltic persisted throughout the week, bringing a combination of low temperatures and largely dry weather as well as some interesting migrants from the east.

Back on the menu this week was one – presumably of the original two – Ruddy Shelduck which, after almost four weeks’ absence, was again by the dam at Pitsford Res

on 12th.  Beyond this, however, there was little to write home about with just two Pintails at Pitsford Res and three at Earls Barton GP – both on 12th – plus two at Stanwick GP on 16th and the two juvenile Garganeys remaining at Pitsford Res and at Ravensthorpe Res until 10th. On 12th, five Red-crested Pochards visited Summer Leys LNR and a female was at Pitsford Res – both of these localities also hosting Great White Egrets with three at Pitsford on 10th-11th, of which at least one remained until 14th, and singles at Summer Leys on 11th and 16th. In the generally underwatched south of the county a Bittern was present in reeds on small lake just south of Farthinghoe NR before flying off low to the north-east on 13th.

This week’s raptors were few, but varied, and included possibly the twentieth county record of Rough-legged Buzzard, which flew low west over the chippings compound at Harrington AF at 10.30 on 12th. Interestingly one – possibly the same – was seen to arrive at Clayhanger Marsh, West Midlands, 80 km WNW of Harrington AF at 12.50 later that same day. Now, assuming a flight speed of 35 km an hour … There was also one in Cambridgeshire on 15th. Somewhat overshadowed by this event were Marsh Harriers at Summer Leys on 14th and 16th and a Merlin at Stanford Res on 14th.

Waders during the period were limited to a count of one hundred and twenty-five Golden Plovers at Daventry CP on 11th and forty at Stanwick GP plus a Dunlin on 16th, two Green Sandpipers at Ravensthorpe Res on 10th and one at Pitsford Res the following day, the first Jack Snipe of the autumn at Stanwick on 16th, plus a sprinkling of Common Snipe, which included approximately forty in a field between Pitsford Res and Scaldwell on 13th, up to seven at Pitsford Res proper on various dates to 14th and one at Hollowell Res on 10th.

A first-winter Arctic Tern arrived at Stanwick GP on 15th (late October records of this species are not unusual) and the same site produced a putative adult Azorean Gull on 10th – echoes of this time last year. Will we ever discover what they really are …

‘Standard’ Yellow-legged Gulls included ten at Stanwick GP on 10th, single adults at Hollowell Res on 10th, Wicksteed Park Lake on 12th-13th and one again at Stanwick on 16th plus two at Pitsford Res on 14th. A first-winter Caspian Gull visited Stanwick on 10th.

The remarkable run of scarce passerines trapped at Stanford Res over the years continued this week, bearing testament to the many hours spent on site and sheer persistence of the Stanford Ringing Group. With the winds full of eastern promise, the team struck silver (if not gold) on 12th with a Yellow-browed Warbler trapped and ringed, followed quickly by Northamptonshire’s second-ever ‘Eastern’ Lesser Whitethroat being pulled from

the net only an hour or so later. Subspecific identification of this species can be tricky – even in the hand – so a couple of feathers which became dislodged during processing were quickly despatched to the University of Aberdeen for DNA analysis … Looking dapper but a lot less rare was the Black Redstart which spent 12th-16th around Dentonwood Lodge

(Yardley Chase), while the only Stonechats reported this week were two/three in Brampton Valley on 12th. Joining a mixed finch flock at Geddington Chase on 12th, a Brambling served as a reminder that winter is surely on its way …

Sandwiched between two high pressure systems, an Atlantic low crossed the country mid-week, bringing heavy rain and a short burst of north-westerly winds before calm weather and easterly winds returned at the week’s end.

The three Barnacle Geese remained at Clifford Hill GP throughout the period, while up to six Pintails were at Pitsford Res from 3rd with singles again at Wicksteed Park Lake on 3rd and Daventry CP on 6th. Having been absent for a couple of weeks, Garganeys reappeared in exactly the same places at Pitsford Res on 6th and at Ravensthorpe Res on 7th. They appeared to be the same individuals as previously observed, so where had they been during the intervening period?

A Red-crested Pochard was found at Stanford Res on 3rd – the same date that the Pitsford flock increased to seven and a ‘surge’ in Great White Egret records occurred. On this date, one flew over Hollowell Res and two were found at nearby Ravensthorpe Res with the latter remaining in place at the same time that two more arrived at Pitsford Res, where one was already present. One remained at Ravensthorpe Res from 4th to 7th and three were at Pitsford Res on the latter date with at least two there to 9th. It appears, therefore, that at least five different individuals were present in the county this week.

One, possibly two, Marsh Harriers were present at Polebrook AF on 4th and another was seen near Raunds on the same date, while the week’s only Peregrine was at Higham Ferrers on 4th-5th and what may be the year’s last Hobby flew south over Harrington AF on 7th.

The latter site stumped up just three Golden Plovers on 6th and 7th but a more respectable one hundred and ninety-eight were counted at Daventry CP on the first of these two dates, while single Ringed Plovers visited Clifford Hill GP on 3rd and Pitsford Res on 6th. Pitsford also produced the week’s only Dunlin and Clifford Hill GP the only Common Sandpiper – both on 3rd. Green Sandpipers were still to be found at three sites with both Pitsford Res and Ravensthorpe Res producing one on 3rd-4th and three on 7th, while another was as Bozeat GP on 8th. A Spotted Redshank flew east at Clifford Hill  GP on 3rd – the same date that three Redshanks visited Ravensthorpe Res and single Common Snipe were at Pitsford Res and Hollowell Res, while six were at Clifford Hill GP; eight more were counted at Bozeat GP on 8th. An adult Yellow-legged Gull was at Hollowell Res on 3rd and up to two adults remained at Pitsford Res throughout the week.

On the scarce passerine front, a Firecrest trapped and ringed at Stanford Res on 9th did its best to make up for the absence of any more of the much anticipated Yellow-browed Warblers resulting from the continuing nationwide invasion.

Otherwise, there were single Stonechats at Thrapston GP on 3rd, Hollowell Res on 7th, Bozeat GP on 8th and Borough Hill on 9th with last week’s four remaining at Blueberry Farm, Maidwell until at least 3rd,

while four Northern Wheatears comprised singles at Clifford Hill GP on 3rd, Pitsford Res and Naseby Res on 7th and Harrington AF on 8th, with the Naseby individual identified as a Greenland race individual.

A high pressure system stationed over the UK brought the longest period of settled weather for some time, resulting in largely sunny days, dry conditions and a constant flow of light easterlies.

One Barnacle Goose at Clifford Hill GP had become three by 1st, while the week’s only Pintail was at Pitsford Res on 27th – the same site continuing to hold up to five drake and one female Red-crested Pochards, one of which was a leucistic individual.

 

 

 

 

 

 

 

 

 

North of the causeway there, two Great White Egrets remained from 26th until at least 1st.

An intriguing record of a ‘ringtail’ harrier at Abington Meadows LNR, adjacent to Clifford Hill GP, involved two sightings three hours apart on 29th. Unfortunately it remained unidentified, in contrast to the readily identified juvenile Marsh Harrier at Pitsford Res two days prior to this and another at Summer Leys LNR on 2nd. Three Peregrines were seen during the period with singles at Harrington Airfield on 26th and at both Higham Ferrers and nearby Ditchford GP on 30th.

This week’s waders included a surprise – and brief – visit to Stanford Res by an Avocet on 1st, while thirty Golden Plovers were near Warmington on 30th and Ringed Plovers were represented by five at Pitsford Res on 26th and one at Clifford Hill GP on 1st. Single Dunlins visited Pitsford Res on 26th and Hollowell Res on 30th while Green Sandpipers numbers held up to some extent with up to three at Pitsford Res on 26th-27th, one at Summer Leys LNR on 26th and three at Ditchford GP on 29th but the week’s only Common Snipe were two at Pitsford Res on 30th. The almost resident adult Yellow-legged Gull at Pitsford Res was reported between 27th and 1st but there were, apparently, no more this week.

Two late (or should that be too late?) Turtle Doves were at Harrington AF on 27th but the week’s star bird was a Yellow-browed Warbler, which was trapped and ringed at Kingswood, Corby on 29th. This was only the 7th County record and the first since 2010.

The first of the autumn’s Black Redstarts was a first-winter at Desborough on 30th and, what must surely be the last now, two more Common Redstarts were trapped and ringed at Stanford Res on 28th and perhaps the last Whinchats were two at Blueberry Farm on 30th. The latter site continued to hold at least four Stonechats and another was present at Pitsford Res on 30th-1st, while the only Northern Wheatear was at nearby Harrington AF on 26th. The week ended with the autumn’s first Rock Pipits at Hollowell Res and Pitsford Res on 30th followed by two at the latter site on 1st.
