As we entered October a heavy dollop of brisk westerlies marked the week just gone but, for all the bluster, there were still birds to be found. With waders now clearly on the ebb, passerines came to the fore – one in particular sparking a bit of a twitch …

This week saw Pitsford Reservoir singled out as the only locality to produce any notable wildfowl, the latter including the presumed same lingering Garganey until at least 2nd and a drake Red-crested Pochard on the same date.

Once again, varying numbers of Cattle Egrets were seen around and about at Stanwick GP, these consisting of two on Roadside Lake on 2nd, eight in the roost there on 6th and six with cattle at North Lake on 7th.

The period’s two Marsh Harriers comprised one at Pitsford on 2nd and the other, a juvenile, at Summer Leys LNR on 6th.

Picking through last week’s leftover waders, the juvenile Grey Plover remained at Thrapston GP’s Titchmarsh Reserve until 3rd, along with the two Ruffs also rolling over there until 2nd. Similarly, Pitsford’s two Ruffs were still present on 1st, one of which remained until 6th.

New in, though, were single Black-tailed Godwits at Hollowell Res, Summer Leys and Earls Barton GP’s New Workings (North) – all on 1st. While the first two of these were one-day birds, the latter remained until 6th, when another was also seen at Ditchford GP.

The same part of Earls Barton also held a Greenshank on 1st-2nd and two Jack Snipes were found at Thrapston on 1st.

The variety of gulls was up this week with, albeit somewhat late, the first Little Gulls of the autumn turning up at Pitsford, where a first-winter was found on 2nd, followed by two first-winters on 5th, one of which remained until the end of the period.

With numbers still depressed, a first-winter Mediterranean Gull visited Boddington Res on 7th, while small numbers of the regularly visiting larger gulls included a first-winter Caspian Gull at Summer Leys on 1st, followed by a second-winter at Daventry CP on 5th and 7th, plus an adult or near-adult at Stanford Res on 6th. Yellow-legged Gulls again maintained a presence with an adult at Earls Barton GP on 2nd and 7th, an adult and a first-winter at Daventry on 3rd and two adults at Pitsford on 6th.

Away from the water, Harrington AF served up a Short-eared Owl on 2nd and a Merlin two days later, on 4th.

But there were no doubts when it came to bird of the week, the award going to Duston’s first-winter Red-backed Shrike – an outrageous find on the edge of suburbia! Being the first in the county since June 2015, this scaly beauty certainly pulled the punters throughout the second half of the day it was present, 3rd October. The occurrence of the 2015 bird was not publicised at the time, neither was the one before that, in July 2011, and you have to go back as far as 2004 to find a twitchable one. In view of this, it was a new bird for a number of county birders. Further details on the Duston bird and a summary of earlier records can be found here.

Another week and another fleeting view of a Ring Ouzel at Harrington came as no surprise on 6th, along with a similarly short-staying Firecrest at Byfield Pool on the same date. Amazingly, the latter is the only one recorded in the county, so far, this year. Meanwhile, the number of Whinchats dwindled to two at Hollowell on 1st and singles at Pitsford on 2nd and 3rd (trapped and ringed on the latter date), in the Brampton Valley between 2nd and 5th and at Clifford Hill GP on 6th. Conversely,  Stonechats went from strength to strength, being recorded from nine localities, with the highest site totals of eight at Earls Barton GP on 2nd and in the Brampton Valley from 2nd to 5th.

Just two Northern Wheatears were made up of singles on a dung heap at Hartwell on 3rd and on the dam at Stanford on 7th, the latter site also producing a Rock Pipit and, like the Firecrest, the first in the county this year, on 1st-2nd.

It was quickly followed, however, by another briefly at Daventry CP on 3rd.

With the delivery of a few more waders and the now-to-be-expected annual Yellow-browed Warbler trapped at Stanford, the past week panned out quite reasonably, ending in a wet and windy blow from the southwest.

Pitsford Res continued to hang on to its Garganey, which was seen intermittently throughout the period, while the only other duck with the potential to set the site alight was a female Ferruginous Duck or hybrid, which evaded positive identification on 27th. It wasn’t reported subsequently. Over to the east, a drake Red-crested Pochard was a one-day affair at Thrapston GP on 28th.

Stanwick GP was the only locality to deliver the week’s Cattle Egrets, numbers of which rose from three on 24th to eleven on 30th. An early morning visit to the roost there may ultimately yield more, of course.

And if last week’s low total of raptors represented slim pickings, then this week we hit rock-bottom with just a single Marsh Harrier seen flying south-east over Clifford Hill GP on the last day of the period.

Waders, though, were another matter entirely. A Grey Plover at Thrapston GP’s Titchmarsh Reserve on 29th was only the third one of 2022 and, following two one-day birds in the spring, sparked a mini-twitch to the site.

Titchmarsh also conjured up another third for the year, a Little Stint, plus a Black-tailed Godwit and two Ruffs – all on the same day as the Grey Plover. Other Ruffs were also available but only for birders visiting Pitsford, where two remained all week, being joined by a third on 25th.

Although playing hard to get, Pitsford continued to hang on to one of last week’s two Spotted Redshanks until 25th, two Greenshanks were there on the latter date and up to two lingered at Earls Barton GP throughout the week. After the autumn’s first, last week, 2 Jack Snipes were found at Ditchford GP on 29th and one remained at Hollowell on 30th.

On the larid front, a first-winter Caspian Gull showed up at Summer Leys on 30th, while Yellow-legged Gulls maintained a local presence with a first-winter at Hollowell on 24th, up to three adults at Pitsford between 26th and 30th, single adults at Thrapston GP on 28th and at Summer Leys on 30th and 2 adults at Earls Barton GP on 29th.

This week’s Merlin, a male, was at Harrington AF on 26th.

But diving into the passerines, what better way to start than with a smart sprite of a Yellow-browed Warbler? It almost goes without saying that this, the first – and probably the last – of the autumn, was pulled from one of the nets at Stanford, which has now chalked up eight (seven trapped and ringed) out of the county’s total of seventeen records. This is the fifth consecutive year that Stanford has struck lucky with this stripey Siberian jewel, the annual occurrence of which there is now taken as a given.  

Also predictable, though clearly not in the same class, was a fleeting view of a Ring Ouzel at Harrington on 24th, the same site holding single Common Redstarts on the same date and again on 28th. Two further birds were seen on 24th – one in the Brampton Valley below Hanging Houghton and the other in a private garden at Grange Park, Northampton. Three sites continued to produce Whinchats throughout the period, including two or three birds in the Brampton Valley and singles at Pitsford and Hollowell, with one remaining at the latter locality on 30th. And the autumn build-up of Stonechats continued, with the highest tally of eight in the Brampton Valley between 25th and 29th. Elsewhere, six were at Earls Barton GP’s New Workings (South) on 29th and at least five at Hollowell on 27th, while up to three were at Pitsford, twos were found at Harrington, Hellidon, Preston Deanery, Teeton and Thrapston and singles at Deenethorpe and Ditchford.

Again, Northern Wheatears were down to the bare bones, with just a single bird in the Brampton Valley on 26th and 29th and, just east of there, two Crossbills flew over Harrington on 24th.

Another predominantly dry week and, aside from a brief south-westerly interlude, winds from the north were the order of the day for the majority of the period. Despite these conditions being far from ideal for scarce autumn migrants, as the week drew to a close, some new and rather more inspiring birds had made it over the county boundary – albeit in small numbers and only for a short period of time …

However, there was nothing majorly new on the wildfowl front and the two Pink-footed Geese of questionable provenance remained with us – the Stanwick GP bird until at least 17th, while the Daventry CP individual was still present on 21st. More sporadic in its appearances this autumn, the female Ruddy Shelduck paid a return visit to Hollowell and Ravensthorpe Reservoirs on 19th, remaining at the latter site until at least 21st, while Pitsford Res again produced a Garganey on 19th-20th and 23rd.

Following last week’s record number of Cattle Egrets, things simmered down somewhat as a return to more normal figures saw eight in flight at Thrapston GP on 17th, the same date on which two flew over Stanford Res – hot on the heels of the site’s first record less than three weeks previously. One was also present at the more traditional location of Ditchford GP’s Irthlingborough Lakes and Meadows LNR on 21st, the same day a Bittern was reported flying south at Broughton.   

This week’s raptors were down almost to the bare bones, with just two Ospreys, both appearing on 18th on opposite sides of the county, including one at Stanford and a juvenile over Thrapston GP’s Titchmarsh LNR. Similarly, two Marsh Harriers were also seen on the same day, 20th, with one flying from the Brampton Valley toward Brixworth and the other at Summer Leys LNR. An unidentified ‘ringtail’ harrier sp. was seen close to Harrington AF on 22nd and was perhaps the Hen Harrier known to have been in the area last week but, then again, perhaps not …

Late September, though, sees the number of passage waders coming through reduced to a trickle, but what may have been lost in quantity was, this week, made up for in quality – if only fleetingly. Black-tailed Godwits were down to single birds at Ditchford on 19th and Daventry on 21st, while Ruffs were similarly reduced to singles at the latter site on 20th-21st and at Pitsford on 21st-22nd, with two there the following day. But it was the 20th which produced two of the week’s star waders. First up was a juvenile Curlew Sandpiper, seen only briefly and photographed at Pitsford then seemingly disappearing into the ether, only to reappear, equally briefly, two days later on 22nd – assuming it was, of course, the same individual. With just the one previous record this year, Curlew Sandpiper is not the regular autumn migrant it once was and it can no longer be guaranteed as an annual visitor to the county, even when there is a national influx and coastal counts reach triple figures. This is a far cry from the way things used to be a couple of decades or so ago, when this species was taken as a given in autumn and many mud-fringed, local reservoirs laid claim to their own.

Sadly, much the same can be said about Little Stint, once taken largely for granted as a regularly occurring autumn migrant in small numbers. Echoing the one-day bird at Thrapston at the end of August, the second of the year made an equally brief stay at Earls Barton GP’s New Workings (North) on 20th. Autumn is not yet over but time is running out for further encounters with this little gem.

Although somewhat further down in the pecking order, the third decent wader on the roll call this week was Spotted Redshank, two of which turned up at the above Earls Barton site on 22nd, some forty-eight hours after the Little Stint. In keeping with the last two species, they did not stay but happily, two – perhaps the same – were found during the evening of the same date at Pitsford Res, where they remained until the following day. These were the first autumn Spotted Redshanks to turn up at this site for four years, but it is unlikely we will ever see a return to the good old days of the last century, when acres of beckoning mud was the autumn norm at Pitsford and numbers of this species were inclined to reach double figures there.

Sticking with Pitsford, a Wood Sandpiper was discovered there on 17th, remaining until the week’s end when it ultimately became overshadowed by the aforementioned taller Tringas. Two Greenshanks were also on site there throughout the week and two also visited Earls Barton on 20th, with one remaining until 23rd. The first Jack Snipe of the autumn was found at Hollowell Res on 21st, still being present on 23rd.

Scarce gulls remained just that. Single first-winter Caspian Gulls appeared at Ravensthorpe on 20th and at Daventry the following day, while Yellow-legged Gulls stretched to one at Pitsford on 21st and seven on 23rd, plus three at Summer Leys on 22nd.

This week’s Merlin was in the Brampton Valley, below Hanging Houghton, on 20th.

All the period’s passerines fell squarely into the chat zone – well, there or thereabouts – and included single Common Redstarts in the Brampton Valley below Hanging Houghton on 18th and 23rd, two near Old on 19th, up to two at Harrington between 19th and 21st, two at Hollowell on 22nd and one at Honey Hill on 23rd.

Whinchats, too, were still very much in evidence with the Brampton Valley holding up to four during the period, at least two were present at Hollowell between 19th and 23rd, two were at Harrington on 21st and one at Willowbrook Industrial Estate, Corby on 18th.

It’s also proving to be a good autumn for Stonechats so far, with birds present at seven localities, including Blueberry Farm, Brampton Valley, Harrington, Hollowell, Pitsford, Welford and Willowbrook Industrial Estate. By the end of the week, Brampton Valley and Hollowell had produced the highest numbers of six and five, respectively.

In stark contrast, though, Northern Wheatears were down to singles in the Brampton Valley on 18th and 21st and up to two at Harrington between 19th and 21st.

The last week in September has a track record for producing American waders and, if the short-term weather forecast for wind and rain is correct, we may yet be in for something interesting over the forthcoming days.

With a mixture of sunshine, occasional early morning mists and hefty showers, backed by largely light south to south-easterlies, the week just gone by took on a distinct autumnal feel. And so it came to pass that the Northamptonshire list became one species heavier, as the nets of Stanford once again worked their magic and delivered something seemingly not on anyone’s radar …

Wading through the wildfowl, at least two Pink-footed Geese of dubious origin remained at large, with the Daventry CP individual still present until at least 8th and the Stanwick GP bird being seen again on 4th and 9th. A Garganey was at Pitsford Res on 3rd – the same site hanging on to just one Red-crested Pochard until 8th. Back over at Daventry, the long-staying first-winter drake Ferruginous Duck remained on site until at least 5th.

A sprinkling of Cattle Egrets included singles at Summer Leys LNR on 3rd and at Stanwick on 3rd-4th but numbers grew at Ditchford GP, where three were initially found on 3rd, followed by five in the Townholme Meadows/St Peter’s Church area on 8th-9th.

Fewer Ospreys were seen this week and included two at Pitsford, briefly, on 5th and a juvenile flying south over Boddington Res on 9th. Similarly, Marsh Harriers were down to just one, a juvenile at Summer Leys on 6th. The vacancy, however, was immediately filled by a ‘ringtail’ Hen Harrier, which proved to be highly mobile between Harrington AF and the Brampton Valley on 4th-5th.

With muddy reservoir margins becoming more extensive and providing a welcoming draw to passage waders,  Black-tailed Godwits were of daily occurrence at, and exclusive to, Pitsford, where seven were present on 3rd-4th and up to five remained for the rest of the period. Naseby Res was, however, the focus for the highest number of Ruffs which had climbed to six by the week’s end. Elsewhere, singles visited Pitsford on 4th and Stanford on 3rd and 4th, one of which was a colour-ringed and flagged juvenile female ringed at Blindheimsvikane in Norway on 27th August. Having travelled 1,204 km in no more than seven days, this is only the 16th Norwegian-ringed Ruff to be recorded in the UK (info from Chris Hubbard).

In the Nene Valley, this week’s one and only Wood Sandpiper remained at Summer Leys from 4th to 7th, two Greenshanks were there on 3rd, while nearby Earls Barton GP’s New Workings (North) continued to hold two throughout the period. Pitsford also produced Greenshanks daily, with up to four on 5th and 9th.

Construction sites with acres of levelled ground are oft favoured by loafing gulls and so it was that this week’s token Mediterranean Gull – an adult – was found among such a flock at Harlestone Park, off New Sandy Lane in Northampton on 5th. This species is still proving thin on the ground, so far, this autumn.

More in evidence, though, were Caspian Gulls and a 2021 German-ringed adult which was found at Naseby on 5th, turned out to be a male that had visited the county last year, when it was seen at DIRFT 3 in August and again in October. Another adult was at Daventry on 8th and a juvenile dropped in at Boddington Res the following day.

There were few Yellow-legged Gulls about during the period, with one at Pitsford on 3rd, a juvenile at Daventry on 4th with three there on 8th and six at Stanwick GP on 9th.

Two juvenile Black Terns visited Boddington on 9th.

Back on dry land, Harrington AF produced a Short-eared Owl on 5th and a Merlin on 5th-6th.

But bird of the week – and probably of the year – was once again at Stanford, where the ringers played a blinder, extracting from the nets a somewhat leftfield catch in the shape of a first-winter Blyth’s Reed Warbler on 8th.

So, after all the hoo-ha at Stanford, another week and another Pied Flycatcher reported from Blueberry Farm, Maidwell the day before was, this time, left looking positively mundane. Meanwhile, the autumn run of Common Redstarts continued unabated with records from seven sites, including Blueberry Farm (Maidwell), Boddington, Brampton Valley, Clifford Hill, Harrington, Stanford and Yardley Chase. The highest counts were four at Stanford on 3rd and four or five at Harrington on 6th.

Whinchats, too, continued to be well represented, with ten sites producing varying numbers, the maxima of which were six in the Brampton Valley on 7th-8th and five at Stanford on 3rd. A male Stonechat was at Priors Hall, Corby on 4th.

Northern Wheatears were found in ones and twos at Barton Seagrave, Brampton Valley, Duston (Northampton), Orlingbury, Summer Leys and Sywell AF, with Harrington producing three on 5th and 8th. The latter site also delivered two fly-over Tree Pipits on 8th.

A mighty week, then … and there is much more of autumn still to come.

During the period in which we crossed the dateline into meteorological autumn, easterlies picked up and garden birds once more came to the fore.

But first, suspect Pink-footed Geese remained on station with the Daventry CP bird seeing out the second week and the Thrapston individual re-emerging on 25th. Absent for a couple of weeks, the female Ruddy Shelduck revisited Hollowell Res on 24th and 31st, two Garganeys dropped in to Cransley Res on 26th and another was found at Pitsford on 30th. Pitsford Res also continued to play host to a small number of Red-crested Pochards, including five there on 20th and one from 27th to 1st. Other diving ducks included a female-type Greater Scaup at Clifford Hill GP on 25th and the long-staying drake Ferruginous Duck, now having shed more of its juvenile feathers, at Daventry CP until 1st.

Escaping the traditional confines of Stanwick GP, where one was present on 21st-23rd, followed by four on 2nd, single Cattle Egrets appeared at Summer Leys on 25th and at Stanford Res – a long-anticipated first for the site – on 28th.

Ospreys and Marsh Harriers have dominated the late summer raptor scene this year and they continued to feature over the period, with singles of the former at Pitsford on 20th and 1st and at Thrapston GP’s Elinor Trout Lake on 22nd, 24th and 28th. Marsh Harriers appeared below Hanging Houghton in the Brampton Valley on 20th, at Summer Leys on 23rd, Stanford Res on 24th and 28th, Stanwick GP on 27th and Daventry CP on 30th.

On the wader front, just one Whimbrel was seen during the period, flying over Clifford Hill GP on 25th. Black-tailed Godwits, on the other hand, maintained a strong presence with thirteen at Hollowell on 25th and varying, single-digit numbers at Summer Leys between 20th and 30th, with a maximum of seven there on 26th. Elsewhere, singles remained at Daventry CP between 20th and 23rd and at Pitsford on 23rd and 27th, with six there on 2nd, one was at Clifford Hill GP on 26th and 31st and two visited Naseby Res on the latter date.

Ruff numbers failed to climb above a site maximum of two – the latter at Naseby Res on 31st-1st – otherwise, singles were found at Daventry on 29th and 2nd, Stanford on 31st-1st, Clifford Hill on 31st and Summer Leys on 1st-2nd.  

Meanwhile, a new bird for 2022, a Little Stint at Thrapston GP on 31st, fortunately remained just that, narrowly escaping the apparent collective hallucinogenic gaze of a group of a dozen or so observers assembled nearby. This week’s one and only Wood Sandpiper checked in at Summer Leys on 30th, the same site holding up to three Greenshanks between 20th and 1st. Other Greenshanks made themselves available at Thrapston on 25th, Pitsford on the same date with one-two there on 1st-2nd and two at Earls Barton GP’s New Workings (North) on 1st.

Thin on the ground so far this year, the week’s only Mediterranean Gull – a juvenile moulting to first-winter – was found at Stanwick on 2nd, while an adult Caspian Gull visited Daventry on 23rd. Up to two Yellow-legged Gulls were seen at Daventry, Pitsford and Stanwick during the period.

Following the first of the autumn’s Black Terns at Thrapston and Stanwick during the previous period, the Stanwick bird remained until 27th and up to three juveniles lingered at Pitsford between 20th and 25th. Not to be left out, the smaller reservoirs of Stanford and Boddington were visited, respectively, by two juveniles on 21st and an adult on 25th.

A male Merlin was seen at Lamport on 24th.

And bird of the week? Well, that honour fell to Wryneck – two of them to be precise, the first of which was found in a garden at Woodend on 21st. Sometimes visible, sometimes not, it was seen again briefly the following day. The second was pulled from a mist net at Stanford, before being rung, on 30th but it was not seen subsequently. Being trapped almost to the day in 2021, this was the ringing group’s fourth in three years.

The ringers at Stanford also struck lucky with a Pied Flycatcher on 28th – only the third ever to be ringed there.

Seemingly now the norm for early autumn, the plethora of Common Redstarts continued with records from twelve sites, including Blueberry Farm (Maidwell), Brampton Valley, Chipping Warden, Fawsley, Harrington, Lamport, Old Stratford, Pitsford, Stanford, Stanford-on-Avon, Thrapston and Woodford Halse. The highest counts were five trapped and ringed at Stanford on 30th and four at Harrington between 22nd and 31st.  

Sharing some of the above localities with the last species, Whinchats, too, were also found in good numbers, with records from Borough Hill, Brampton Valley, Clifford Hill, Fawsley, Harrington, Hollowell, Old Stratford and Stanford – Harrington and Hollowell producing the maximum of five apiece on 28th and 29th, respectively.

Northern Wheatears were a little less widespread, with no single site producing more than one bird. Borough Hill, Brampton Valley, Clifford Hill, Harrington, Pitsford and Stanford all featured during the period.

Following an earlier than normal autumn passage, just one Tree Pipit was found, at Harrington, on 29th, while a Corn Bunting appeared unexpectedly at Ditchford GP on 21st.

A return to temperatures more normal for mid-August, variable wind directions and some seriously heavy showers characterised the week just gone. A surprise Shag in a Towcester garden headed up a veritable mixed bag of birds, which included the extended dwell time of the juvenile drake Ferruginous Duck at Daventry CP.

It was at this location that things were beginning to look decidedly dodgy as last week’s on-site Pink-footed Goose showed signs of being paired with one of the Greylags present. It remained until the end of the period. Unless there are two different birds involved, the on and off eclipse drake Garganey at Pitsford Res also saw out the week there, as did two Red-crested Pochards. Another eclipse drake Garganey visited Stanford Res on 14th while, back at Daventry, the juvenile drake Ferruginous Duck also remained throughout.

No longer confined to the winter months, Bittern, it seems, has become a bit of a Martini bird in Northants, nowadays having the potential to be found any time, any place, anywhere. This is no doubt a result of its continually increasing UK breeding population, a measure of which is reflected in the number of booming males – a record 228 in 2021. Following one at Summer Leys LNR recently, another showed well on the edge of the reeds at Stanwick GP on 15th. They are still not easy to come by …

Stanwick also hosted a Cattle Egret between 16th and 19th, while this week’s Great Egrets were too readily available at Ditchford GP, Stanwick, Summer Leys and Pitsford – the latter site producing a maximum of up to five birds.  

Putting aside the rarity value of a certain Daventry duck, the bird of the week slot was rightly occupied by a juvenile Shag. In this instance, a garden pond in Towcester came firmly under the spotlight, playing host for the best part of the day, on 13th. Feisty and approachable during its stay, the bird had departed by the evening but not before it had consumed the pond’s one and only goldfish.

This week’s Ospreys were limited to the area around Hollowell Res, with two there on 16th, one on 18th and one flying south over the nearby village of Guilsborough on 19th. The only other raptor of note was Marsh Harrier, Summer Leys producing a juvenile on 13th, Harrington an adult male on 15th and the Brampton Valley below Hanging Houghton one on 15th and 18th.

When compared to the last review period, things were looking up on the wader front, kicking off this week with eighteen Whimbrels flying south over Daventry on 16th – a decent flock size for Northants, if ever there was one. Black-tailed Godwits were also more in evidence, Stanford leading on numbers with seventeen circling the site before flying west on 19th. On the ground, Summer Leys produced birds on a daily basis, which comprised probably five different individuals during the period. Elsewhere, singles were at Hollowell on 17th, Daventry on 17th-19th and at Naseby Res on 18th.

Ruff numbers, too, were on the up, Pitsford laying claim to the lion’s share with three on the ground and six more flying over on 16th and one remaining the following day. Stanwick subsequently produced one on 17th and another was at Summer Leys on 18th, while an out-of-season Sanderling appeared at Thrapston GP on the first of those two dates.

This week’s one and only Wood Sandpiper was at Earls Barton GP’s New Workings (North) on 18th-19th, while single Greenshanks visited Summer Leys on 16th and Naseby on 18th.

The week’s only Caspian Gull – an adult or near-adult – was again at Daventry on 16th, while Pitsford held up to three Yellow-legged Gulls, Daventry produced a first-summer on 17th and an adult visited Naseby the following day.

After a very lean spring for the species, the first of the autumn’s Black Terns appeared at Thrapston GP on 17th and it seems highly likely this was the same bird relocated at Stanwick the following day, remaining there until 19th.

Heading up this week’s passerines was a Pied Flycatcher, located in a boundary hedge at Hollowell on 18th. As is often the case, it remained highly elusive and its stay was equally brief. Chalk and cheese, though, the appreciable run of autumn Common Redstarts continued, producing birds at seven localities, including Blueberry Farm (Maidwell), Brampton Valley, Harrington AF, Lamport, Lilbourne Meadows NR, Pitsford Res, Stanford Res. The highest number was four or five at Harrington on 15th and 18th, with one trapped and ringed there on the latter date.

Whinchat numbers improved somewhat this week, Harrington producing four on 14th and 17th, Blueberry Farm (Maidwell) three on 18th, up to two in the Brampton Valley between 14th and 19th and singles at Stanford on 15th and 19th. An early autumn Stonechat put in an appearance at Wollaston Mill, near Summer Leys, on 14th. Northern Wheatear numbers continued to move slowly upward, with Harrington producing singles on 13th and 17th and two on 17th. Elsewhere, singles were found in the Brampton Valley on 13th and 18th, Thrapston on 16th, Summer Leys on 7th and Welford Res on 18th, while single Tree Pipits flew over Blueberry Farm on 13th and Duston on 19th and one was below Hanging Houghton in the Brampton Valley on the latter date.

No let up in the dry weather saw more migrants on the move, including some early bonus birds, comprising both the bold and the bizarre. Falling squarely into the latter category was the first ‘pure’ Ferruginous Duck in Northamptonshire for eleven years.

Following the short-term scare elicited by a hybrid at Stanwick back in January 2020, there is no doubt about the identification of this week’s bird, a juvenile male, which turned up at Daventry CP on 31st, remaining there throughout the week. What may be in doubt, however, is its origin. Clearly one of the two which turned up a stone’s throw away, at Draycote Water, it remains a mystery as to what they are doing there, unseasonally, in late summer – especially as this mirrors last year’s occurrence at the same locality around the same time. Is there a local wildfowl collection in the vicinity, from which captive-bred birds are escaping before they are pinioned? The jury is out …

Despite some twenty-five previous records, Ferruginous Duck – currently a ‘BB rarity’ – is now a seriously rare bird in the county. The last acceptable one was a drake at Pitsford Res, returning for its third year, from 28th September to 14th October 2011, while the only other record this century was a first-winter drake at Daventry CP from 15th December 2002 to 10th February 2003, and what was believed to have been the same bird visiting at Hollowell Res on 1st February 2003.

In contrast to the above, six Common Scoters (five drakes) at Pitsford in no way proved contentious when they dropped in while undertaking their overland moult migration, on 31st. Pitsford also held up to four Red-crested Pochards (two drakes) throughout the week, along with an eclipse drake Garganey on 1st, ahead of what was likely to have been the same bird there again on 4th-5th.

Last week’s Bittern was seen again at Summer Leys LNR on 30th while, back at Pitsford, two Cattle Egrets paid a brief visit the following day. The latter site also produced the week’s maximum count of Great Egrets with five present on the 5th, while Summer Leys and Thrapston GP held one apiece during the period.

Heading up the raptors, single Ospreys were seen over Hollowell Res on 30th and 31st, Stanford Res on 30th and 5th and at Daventry on 3rd. Marsh Harriers remained in the spotlight this week, though, with one flying west over Sulby on 30th, and singles at Stanford on the same date, Summer Leys on 30th-31st and 4th and over Pitsford on 5th.

On the wader front, two Whimbrels flew west over Ditchford GP and over Summer Leys shortly afterward on 30th and one flew over Pitsford on 31st. Pitsford also scored a respectable twenty-eight Black-tailed Godwits – albeit fleetingly – on 31st and a modest ten flying south there, on 4th. Four and seven were at Summer Leys on 31st and 4th, respectively, four visited Stanford on 5th and singles were found at Daventry, Hollowell and Pitsford on 1st.

The week’s only Greenshank was mobile around Summer Leys between 30th and 2nd, the same site hosting an adult Wood Sandpiper between 30th and 1st while, a little further west along the Nene valley, a juvenile Wood Sandpiper spent the day at Earls Barton GP’s New Workings (North) on 4th.

Following the first pop-in juvenile Mediterranean Gull of the autumn at Stanford last week, another was there equally briefly on 4th. Upsizing, Yellow-legged Gulls peaked at seven at Pitsford on 31st, followed by three there on 1st and at least one lingering throughout the week. Elsewhere, single birds visited Stanford on 31st and 2nd, Harrington AF and Stanwick GP on 2nd and Wicksteed Park Lake (Kettering) on 4th.

A Short-eared Owl was captured on a trail-cam, positioned in the Brampton Valley, during the early hours of 5th.

A short hop away at Harrington AF, topping this week’s passerines were two rather nice Pied Flycatchers, present for one day, on 30th. A great find and a welcome distraction from the run-of-the-mill bits and pieces coming through hitherto. More were to follow, with 1st seeing another located at Blueberry Farm, Maidwell and yet another down in in the south-west of the county, at Eydon, on 4th.

A scarce, much admir’d and locally sought after migrant, Pied Flycatcher is an almost annual visitor, producing an average of three records per year, although 1995 saw an amazing thirteen appearing, ten of which were in autumn. Though rare, records in July are not without precedent but August remains the peak month for occurrences.

Common Redstarts were again in profusion this week with up to two at six localities including Blueberry Farm (Maidwell), Clifford Hill GP, Harrington AF (where one was trapped and ringed on 4th), Lamport, Pitsford Res and Woodford Halse. Two more  Northern Wheatears appeared – one at Wollaston on 4th and the other in the Brampton Valley below Hanging Houghton the following day. A single Common Crossbill flew over Harrington on 31st.
