Month: October 2013

This week’s weather was dominated by westerly or southwesterly winds, which produced showers and some short periods of heavy rain. Some interesting migrants found their way to the county while several long-stayers seemed set to remain for a while to come.

Following last week’s Egyptian Goose at Stanwick GP, two more were found at adjacent Ditchford GP on 23rd and the drake Mandarin Duck from Wicksteed Park Lake had moved to nearby Kettering Leisure Village Lake on 19th. The long-staying eclipse drake Red-crested Pochard remained at Stanford Res until at least 19th and another joined the three at Pitsford Res on 23rd and the total had increased to nine by 25th. A Bittern was located at Stanwick GP on 25th while the two Great White Egrets remained at, or around, Pitsford Res to at least 23rd with one until 25th.

On the raptor front, a male Hen Harrier was found at Blueberry Farm, Maidwell on 22nd, where it remained until the next day when a ‘ringtail’ was also discovered at the same site, being reported again there on 24th. The lingering Osprey at Stanford Res was still present there on 22nd, single Merlins visited Harrington AF and Pytchley Golf Course on 24th and Peregrines were found at Blueberry Farm and at Ditchford GP on 22nd and 23rd respectively.

Late autumn migrant Ringed Plovers included singles at Pitsford Res and Stanwick GP on 19th while numbers of Golden Plovers continued to build at six localities, with a maximum of c.600 at Clifford Hill GP on 19th. The only Dunlin this week was one at Pitsford Res on 23rd and a Jack Snipe was discovered at Grange Park, Northampton on the same date, while a Black-tailed Godwit visited Summer Leys LNR on 19th before moving further along the Nene Valley to Stanwick on 20th, remaining there until 25th. The latter site produced a Redshank on the same date, single Green Sandpipers were at Ravensthorpe Res from 19th to 23rd and at Pitsford Res on the latter date and a late Common Sandpiper was also found at Pitsford Res on 22nd.

A first-winter Mediterranean Gull appeared at Ravensthorpe Res on 23rd and five Caspian Gulls included an adult at Stanwick GP on 19th with two adults and a first-winter there on 22nd and an adult at Pitsford Res on the latter date. The elusive adult Azorean Yellow-legged Gull made one of its unpredictable appearances at Stanwick GP on 19th and approximately twenty Yellow-legged Gulls were also there on the same date and on 22nd, when an adult was also at Pitsford Res and two adults there on 25th.

Short-eared Owls remained scarce with just one at Harrington AF on 19th and 24th, the same site holding a first-winter Ring Ouzel throughout the period as well as what for

many locals was ‘bird of the week’, a Great Grey Shrike on 24th and 25th. True to form,

it remained highly mobile along the scrub belt between the first and third bunkers and the main concrete track as previous individuals have done in the past. Birders admiring the shrike also discovered a Black Redstart there on 24th.

Stonechats – locally scarce this year – were seen in Sywell early in the week and at Blueberry Farm on 24th but the title of rarest bird of the week goes to the Richard’s Pipit, which was flushed from a weedy field behind the dam at Daventry CP before moving to an adjacent field prior to flying off toward Borough Hill. This is only the 9th Northants record and follows hot on the heels of last year’s at almost the same locality. Single Rock Pipits, common by comparison, appeared at Stanford Res on 19th and at Stanwick GP on 22nd and two Crossbills flew over Harrington AF on 24th.

The week kicked off with a slow-moving low pressure system sitting just over south-eastern Britain and adjacent mainland Europe, which produced significant north-easterly winds accompanied by low cloud and rain – ideal conditions for pushing species more normally associated with the coast into Northants.

Part of last week’s Whooper Swan movement spilled over into this week with three adults flying north-east over Boddington Res just before dusk on 13th. An Egyptian Goose was at Stanwick GP on 16th, a Ruddy Shelduck was again reported fleetingly from Pitsford Res on 14th and a drake Mandarin Duck visited Wicksteed Park Lake on 15th.  A single Pintail was found at Thrapston GP on 12th, two were at Stanwick GP the following day and up to eight were counted at Pitsford Res on 13th-14th, while the menu of scarce diving ducks became more extensive this week with the eclipse drake Red-crested Pochard still at Stanford Res to 17th, singles at Clifford Hill GP on 13th and Wicksteed Park Lake on 14th and three at Pitsford Res on the latter date. A female or first-winter Scaup visited Daventry CP on 17th and storm-driven drake Common Scoters appeared at Pitsford Res (two) and Clifford Hill GP on 13th

and Clifford Hill GP also hosted the year’s only Red-breasted Merganser on 12th, while last week’s Goosander remained on the fishing lake at Wicksteed Park all week.

Also from last week, the Stanford Res Black-necked Grebe reappeared on 18th.

Hot in off the North Sea, Northamptonshire’s thirty-fourth Gannet, a juvenile, splashed down early in the afternoon of 14th on Thrapston GP’s Barclaycard Pit, where it remained, showing well, until dusk.

This species has appeared in no more than three years out of the past ten with September being the peak month of occurrence in the county.

All three of last week’s Great White Egrets – two at Pitsford Res and one at Stanwick GP – remained until at least 15th

while the county’s third-ever Glossy Ibis appeared at the latter site on 12th. First seen flying high west over the eastern pits there, it whiffled down and appeared to land on the A45 Lay-by Pit. Despite a thorough search by a number of local observers it was not relocated. Uncannily – or perhaps predictably – this bird followed exactly the same pattern of occurrence as the previous two: one observer, less than twenty minutes, gone. This would have been the case other than for an unconfirmed report of its revisiting the same site briefly on 15th so it could still be lurking somewhere in the Nene Valley, although Northants appears to be a Teflon-coated county as far as this species is concerned. Will there ever be one which stays long enough for the birding masses to catch up with it?

The trio of notable raptors this week include an Osprey lingering at Stanford Res all week, a Merlin at Blueberry Farm, Maidwell on 17th and a couple of Peregrines at Hellidon on 12th.

While numbers of Golden Plovers began to build for the winter, with three hundred and fifty at Clifford Hill GP on 13th, wader passage in general continued to dwindle. Dunlin numbers were down with up to three at Pitsford Res between 12th and 15th, up to two at Clifford Hill GP during the same period and two at Stanwick GP on 12th. The only Ruff this week were singles at Pitsford Res on 12th and Clifford Hill GP on 14th, a Bar-tailed Godwit flew south at Pitsford Res on 13th along with a Curlew while another Curlew flew east at Stanford Res on 12th and two Green Sandpipers were also at Pitsford Res on 14th.

Two Caspian Gulls were found at Stanwick GP on 12th and an adult was again at Thrapston GP on 14th along with four Yellow-legged Gulls while single adult Yellow-legged Gulls visited Clifford Hill GP on 12th and Pitsford Res on 15th. The depression also dumped Little Gulls – all first-winters – at three localities: Summer Leys on 12th, Thrapston GP from 12th to 14th and Stanford Res from 13th to 15th as well as a typically late juvenile Arctic Tern at Clifford Hill GP on 13th.

On the passerine front, a Firecrest was discovered with a tit flock at Titchmarsh Wood on 17th, straggler Swallow duos were at Clifford Hill GP on 12th and Pitsford Res the following day and a Ring Ouzel showed well at Hellidon – if only for a short while – on 12th. The same locality also hosted a Greenland Wheatear at the same time and a male Stonechat was discovered at Pitsford Res on 14th while single Rock Pipits appeared on cue at Hollowell Res on 13th and at Thrapston GP the following day. More Bramblings arrived this week with singles at Hellidon and Stanford Res on 12th and at Woodend near Blakesley on 18th, with two at Geddington Chase on 17th and approximately twelve Crossbills flew over Spratton on 16th with another over on 17th and several over Daventry CP on the same date.

The relatively warm south-westerly airstream at the beginning of the week had given way to cold north-easterlies and rain by the week’s end. A phenomenal 33,000+ Redwings were counted migrating over one point in neighbouring Bedfordshire on 10th as more winter visitors appeared in Northants.

Yes, winter’s intent was announced by the arrival of several species this week, kicking off with six Whooper Swans flying east just before dusk fell at Stanwick GP on 10th. The same, or perhaps a different flock was seen flying south-west at Thrapston GP the following morning with a lone individual was also seen flying north-east there and nine adults briefly at Hollowell Res the same day. The Pitsford pair of Ruddy Shelducks was present until 8th but they have become highly mobile and may still be present somewhere on the reservoir. Elsewhere, scarcer wildfowl were represented by last week’s Pintail remaining at Hollowell Res until 10th, singles at Stanford Res on 5th and Thrapston GP on 11th and four or five at Summer Leys LNR on 7th, the latter being joined there by three Garganey on the same date, while an eclipse drake Garganey was also at Clifford Hill GP on 5th.

Last week’s eclipse drake Red-crested Pochard was still at Stanford Res on 5th, five Common Scoters (two drakes) appeared at Hollowell Res and another at nearby Ravensthorpe Res on 10th and the first Goosander of the season was on the fishing lake at Wicksteed Park on the same date.

Hot on the heels of last week’s two Great White Egrets, two more – this time together – arrived at Pitsford Res on 8th with at least one remaining there until 11th. Meanwhile, in the Nene Valley, another was found at Stanwick GP early morning also on 11th and a Black-necked Grebe – a species proving scarce this autumn – appeared at Stanford Res on 5th.

Raptors were also in short supply this week with a ‘ringtail’ Hen Harrier flying west at Summer Leys on 11th and a Peregrine there on 6th, while a juvenile visited Stanwick GP on the same day and an adult was there on 9th.

Wader passage is now at an understandably low ebb and there were few new arrivals. Ringed Plovers at Pitsford Res dropped from six on 5th to four by 9th and two were still at Clifford Hill GP on 5th where there were approximately two hundred Golden Plovers on 9th with five at Summer Leys on 6th. The long-staying Grey Plover remained at Stanwick GP until early morning on 6th and another flew east over Hollowell Res on 5th. The two Little Stints at the former locality remained until 5th and the same site held a Dunlin from 5th to 9th, three were at Pitsford Res from 5th to 7th with one there on 8th-9th and two on 11th and two were at Clifford Hill GP on 5th. The only Ruff this week was one at Daventry CP on 7th, the same site producing a flock of fifteen Black-tailed Godwits for just thirty minutes on 5th, while another was at Stanwick GP on the same date. Just one Common Sandpiper was found – at Pitsford Res – on 9th, the same site producing the week’s only Green Sandpiper on 8th.

Single first-winter Mediterranean Gulls were at Daventry CP on 8th and 11th and a fourth-winter Caspian Gull visited Stanwick GP on 5th, an adult was there on 8th and another adult was found at Thrapston GP on 11th. Amazingly, ‘the’ (or another) Azorean Yellow-legged Gull was back at Stanwick GP for just a couple of minutes on 8th, again giving observers no chance to catch up with it and approximately thirty Yellow-legged Gulls were there on the same date. Two more were at Hollowell Res on 5th, six were at Thrapston GP on 11th and an adult remained at Pitsford Res all week.

A late Willow Warbler was at Hardingstone on 11th, a male Ring Ouzel – only the second of the autumn – was found at Hollowell Res on 10th and the winter’s first Fieldfares – three of them – flew over Stanford Res on 9th. Departing summer visitors included last week’s Whinchat remaining at Clifford Hill GP until 5th and what were probably the last Yellow Wagtails of the year at Hollowell Res and Brackley on the same date. More inbound winter visitors included the first Bramblings at Stanford Res and Summer Leys on 5th, followed by one at Stanwick GP and six west over Thrapston GP on 11th.

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.
