Rarity Round-up, 20th to 26th June 2020

A hot and humid period, with local temperatures hitting 30°C on the last day of the week, by which time it was clearly evident waders were returning and we were in the midst of a Crossbill invasion …

The Pink-footed Goose, last seen with Greylags at Pitsford Res on 9th June, was back there again on 25th, a return mirrored by the female Ruddy Shelduck at Hollowell Res which, after being absent from 12th June, reappeared on the same date. Stanwick GP’s Red-crested Pochard was again on site on 25th, while last week’s two drake Common Scoters remained off the sailing club at Pitsford until 20th.

After last week’s announcement that Cattle Egrets had once again bred successfully at Ringstead GP, four – possibly five – fledged juveniles were seen there on 21st but the only Great Egrets during the period were at Hollowell Res, where one on 24th-26th was joined by another there on 25th.

Hollowell also produced single Ospreys on 20th, 24th, 25th and 26th, one of which was wearing a ring identifying it as a female from Rutland Water. The only other Ospreys were singles at the other oft favoured fishing localities, Stanford Res and Thrapston GP – both on 22nd. Surprisingly, none was reported from Pitsford this week.

Although it’s only June, the return wader passage is picking up already. A juvenile Avocet visited Pitsford Res on 25th, remaining throughout the afternoon and into the evening. Icelandic Black-tailed Godwits have started moving through in small numbers, with Summer Leys LNR hosting two on 24th, one on 25th and five on 26th, the same site producing an early Wood Sandpiper along with a Greenshank on the latter date.

Just along the Nene Valley, at Stanwick, Mediterranean Gulls have once more successfully bred following a year’s absence since they first bred there in 2018. Two adults and a recently fledged juvenile were observed on 25th.

Elsewhere, one was seen in flight over Barton Seagrave on 21st. The only other reasonable larid of note was a second-summer Yellow-legged Gull at Hollowell on 20th and 26th. Hollowell also held a first-summer (or second-summer) Arctic Tern from 20th to 22nd – its occurrence, identification and ageing having already been discussed here.

Beyond this, the week belonged to Crossbills. The UK is currently enjoying a national influx, said to be the result of a ‘bumper breeding season’, with many east coast sites recording huge numbers on the move, one of the biggest including more than twelve hundred south over Scarborough during the morning of 25th.

Crossbill, Hollowell Res, 26th June 2020 (Gary Pullan)


Many quickly made their way inland, resulting in their appearance in at least eleven localities in Northamptonshire. The majority of sightings were fly-overs and numbers ranged from singles to double-figure counts of sixteen at Bucknell Wood on 24th and fourteen at Harlestone Heath on 25th. The movement continues …

‘First-summer’ Arctic Tern

An Arctic Tern at Hollowell Reservoir provides the opportunity to study a plumage rarely seen in the UK in summer.

Found by Gary Pullan during the morning of 20th June, a first- (or possibly second) summer Arctic Tern was still present there yesterday, allowing Jon Cook to capture some clearly instructive images of a bird which would normally be expected to spend the northern summer south of the Equator. A tiny proportion is, however, known to accompany adults when they move north in spring, although they are likely to wander and do not usually appear in breeding colonies.

Any tern with a white forehead and a predominantly dark bill, seen in late spring/early summer, is likely to draw attention, as it stands out from the typical fully black-capped, red-billed Common and Arctic Terns normally encountered on spring passage or, in the case of Common Tern, breeding in the county. Identifying it to species is one thing and ageing it correctly is another.

Jon’s excellent series of photos nicely illustrate its identity, which is straightforward, given good views in the field. In the first image, against the light the translucent primaries are clearly visible, immediately putting the bird in the Arctic camp before any full assessment of the plumage detail.

First-summer Arctic Tern, Hollowell Res, 22nd June 2020 (Jon Cook)

A check of the upperside of the primaries also adds to this identification, as they are ‘clean’ and uniform, lacking the darker, unmoulted outer primaries of both first- and second-summer Common Tern.

First-summer Arctic Tern, Hollowell Res, 22nd June 2020 (Jon Cook)
First-summer Arctic Tern, Hollowell Res, 22nd June 2020 (Jon Cook)

There is a darker bar on the leading edge of the wing coverts, which looks more prominent in some photos than others. First-summer Common Tern would also show this but in combination with darker (not white) secondaries.

First-summer Arctic Tern, Hollowell Res, 22nd June 2020 (Jon Cook)

The overall ‘neat’ proportions also look right for Arctic Tern, although in some photos the bill looks rather long but this is probably accentuated by the white forehead.

Leg colour is said to be variable – see, for instance, Terns of Europe and North America (Larsson & Malling Olsen, 1995) and this bird has a definite redness associated with its legs.

First-summer Arctic Tern, Hollowell Res, 22nd June 2020 (Jon Cook)

Bill colour of second-summer is said to be red like that of an adult but with a dark tip to the upper mandible and a darker base. The images above appear to depict an all dark bill but the one below, from Adrian Borley, taken on 20th in different light conditions, appears to show some redness in the bill’s centre, as well as some brown tones to the dark crown. The underparts are a mixture of grey and white. The last two features are said by Larsson & Malling Olsen (1995) to be indicitave of second summer birds.

First-summer Arctic Tern, Hollowell Res, 20th June 2020 (Adrian Borley)

The Hollowell bird appears to show features of both first- and second-summer. Any further comments on its age would be welcomed.

Rarity Round-up, 13th to 19th June 2020

A slow-moving low pressure system over the UK dragged in a mixed bag of warm air and showers from the east, on the back of which were just about enough birds to keep spirits up during a traditionally quiet period.  

Single Garganeys at Hollowell Res on 19th and Pitsford Res on 18th would appear to be firsts for both sites this year, while the latter locality also produced two drake Common Scoters off the sailing club there on 17th-19th – both showing signs of immaturity. This ties in nicely with moult migration movements of one-year old birds, some of which start to move as early as May, after curtailing their spring migration to the north-east before reaching the breeding range. Perhaps not as exciting but a might more colourful, the drake Red-crested Pochard continued its stay at Stanwick GP until at least 16th.

Four Cattle Egrets were at Ringstead GP on 15th, two of these being seen at adjacent Stanwick GP the following day. With their continued presence in this part of the Nene Valley, it comes as no surprise to discover that, following successful breeding at Ringstead last year, they have bred there again this year – three young being present on 19th.

The Great Egret at Thrapston GP remained until 15th, being joined by another on 13th, while one was also seen at Stanford Res on 15th-16th.

Four localities produced Ospreys this week. One flew north-east over Spratton on 13th, one was over Bulwick on 14th and two at Ravensthorpe Res on the same date, while another visited Pitsford Res on 17th.

Following the Irthlingborough Common Cranes at cockcrow on 16th May, another flew north over East Hunsbury, Northampton at a similarly early hour on 16th. There have been twenty-two accepted records to the end of 2018. Sometimes insomnia pays dividends.

More late spring Black Terns appeared this week – this time at Clifford Hill GP on 13th, when three were present, two of which remained the following day.

Scarce passerines were at a premium and represented only by a single Crossbill, which was seen at Hardwick Wood on 17th. June-July is the time when this species is on the move so hopefully there will be more to come.




Rarity Round-up, 6th to 12th June 2020

Showers, a northerly blow and below average temperatures provided the overall backdrop for this week’s birding, although the wind had developed a strong easterly component by midweek. ‘Staying alert’ could not have been more appropriate advice for the period – there are clearly some quality birds still being found out there …

In a month not normally recognised for wildfowl, there was a decent crop – although how genuinely ‘wild’ they are is a matter of opinion. It would appear that Clifford Hill GP’s Pink-footed Goose relocated to Pitsford Res, where it was discovered in Scaldwell Bay on 9th. At least it’s moving in the right direction. A female Ruddy Shelduck was found at Hollowell Res on 7th, remaining there at the week’s end.

Female Ruddy Shelduck, Hollowell Res, 12th June 2020 (Jon Cook)
Female Ruddy Shelduck, Hollowell Res, 12th June 2020 (Jon Cook)

It is easy to speculate this is last year’s individual, returning to the same site to see out its summer moult. Having not been reported for more than a week, it appears that Stortons GP’s drake Red-crested Pochard has relocated to Stanwick GP, where one was present from 6th until at least 11th. Back at Hollowell, four Common Scoters dropped in on 8th.

Common Scoters, Hollowell Res, 8th June 2020 (Martin Swannell)

Following last week’s Brampton Valley Quail, another was singing at Harrington AF on 7th, proving itself a popular draw for listeners until 9th. It was sound-recorded during its stay. One was also reported from Haselbech on 7th. Fifty years of Northamptonshire Quail records are depicted here.

Stanwick continued to host at least two Cattle Egrets throughout the period, while the Great Egret at Thrapston GP was seen again on 9th.

Three localities produced Ospreys this week, down from last week’s seven. Singles visited Stanford Res on 7th and 10th, Hollowell on 7th, 8th and 12th and Thrapston on 10th and 11th, where Elinor Trout Lake is a popular draw.

Thrapston also produced an Avocet on 11th and three were on site there the following day, on 12th. Also in the Nene Valley, two Black-tailed Godwits visited Summer Leys LNR on 8th, followed thereafter by one on 10th-11th and one at adjacent Earls Barton GP, also on 11th. It is not known if all sightings were of the same two birds, or whether four were involved. Those on 11th involved both races, the commonly encountered Icelandic race islandica at Earls Barton and the much scarcer ‘continental’ race limosa at Summer Leys.



            Gulls and terns featured well for June. A first-summer Little Gull visited Stanford Res on 11th, a second-summer Yellow-legged Gull was at Hollowell Res on 8th and a late spring Black Tern appeared at Stanwick GP on 6th.

Following the ephemeral Rose-coloured Starling in Wellingborough on 26th May and the inevitability of an invasion, the floodgates duly opened and the UK received its fair share of ‘Rosy Pastors’ – in excess of seventy at the time of writing. As they crossed the country, expectations were running high at a local level before one was eventually found in a garden in Hackleton on 9th. It remained long enough for a quick pic and then it was off, never to be seen again. Or was it? It, or another, was reported flying between gardens in Great Houghton, only 4 km to the north, on 9th and 10th. While all this may have been somewhat vexing, to say the least, for those of us routinely cruising and scanning suburbia, scrupulously checking our local Starling flocks, it also offers hope and inspiration that persistence may yet pay off. There are surely more to be discovered. Keep calm and carry on kerb-crawling …

The only other passerines of note were Crossbills. One flew over Pitsford on 7th and approximately twelve were in Yardley Chase, at Denton Wood, the following day.

Rarity Round-up, 30th May to 5th June 2020

Meteorological spring went out with a bang, the last day producing the county’s 6th Caspian Tern. So, too, did the weather and by the end of the week high pressure, high temperatures and an easterly airstream had all given way to cool northerlies and showers.

There were no reports of Clifford Hill GP’s Pink-footed Goose beyond 31st, while Stanwick GP’s drake Garganey remained until at least 2nd and one/two drakes were still frequenting Summer Leys LNR/Earls Barton GP on 3rd with at least one remaining on 5th. New in this week were two Greater Scaups at Daventry CP on 1st, surprisingly remaining on site until at least 4th.

June is generally recognised as being the month for Quail and, right on cue, a male was singing in the Brampton Valley, between Cottesbrooke and Hanging Houghton, on the evening of 1st, remaining in situ early the following morning. This species appears to be increasingly difficult to catch up with locally, despite being recently identified as now in partial recovery following a protracted period of population decline. It is estimated that there are 540 singing males in the UK in summer (RSPB).

Stanwick continued to host Cattle Egrets with four present on 31st and again on 5th, while a Great Egret remained at Thrapston GP on 30th and one flew over Stanford Res on 3rd.

Cattle Egret, Stanwick GP, 1st June 2020 (Steve Fisher)

On the raptor front, the week belonged to Ospreys. Seven localities featured – some more frequently than others. The reservoirs fared well, with Pitsford hosting singles on 30th, 2nd, 3rd and 4th, Stanford produced singles on 31st and 1st plus two on 2nd, while Cransley and Hollowell logged one a piece on 2nd and 3rd respectively. One also flew north over Harrington AF on 2nd and in the east of the county, two drifted north over Barnwell CP on 3rd and singles visited Thrapston GP/Thorpe Waterville on 31st and 2nd. The first of these Thrapston birds wore a blue ring bearing the inscription ‘S1’ in white and it transpired it was a male which had been ringed as a chick at the Manton Bay nest at Rutland Water on 30th June 2015.

Male Osprey, Thorpe Waterville, 31st May 2020 (Ady Leybourne)

Further information reveals ‘S1’ first returned to the UK in 2017 and was seen at Poole Harbour and also Rutland Water that summer. It was subsequently satellite-tagged on 9th August 2018 at a site in Rutland. This has since provided valuable data on the bird’s local movements and annual migration to an island off the coast of Guinea-Bissau.

Male Osprey, Thorpe Waterville, 31st May 2020 (Ady Leybourne)

This spring it left Guinea-Bissau on 8th March and arrived back in Rutland on 4th April. It has subsequently established a new territory in Rutland but has also been ranging widely in the local area. The satellite data show that ‘S1’ isn’t a frequent visitor to the Thrapston area and so other recent sightings – mainly from Elinor Trout Lake – clearly refer to one or more different birds. There are several unattached males in the Rutland Water area and these individuals often range widely on a day-to-day basis (Tim Mackrill, RDWF). Also in the Nene Valley, a Marsh Harrier flew north-east at Summer Leys on 31st.

With the wader passage all but over, a Sanderling paid the briefest of visits to Boddington Res on 5th and an ‘unseasonal’ Green Sandpiper – perhaps an early autumn migrant – at Cransley Res on 2nd, was worthy of mention.

June is not normally recognised as a prime month for gulls, so an adult Mediterranean Gull flying over Wellingborough on 3rd, a second-summer Yellow-legged Gull at Pitsford on the same date and an adult at Daventry CP on 5th were about par for the course. Both were largely of no consequence in comparison to the star of the week, though, the magnificent Caspian Tern, which flew over Stanford Res on 31st – sadly without stopping.

Caspian Tern, Stanford Res, 31st May 2020 (Chris Hubbard)

This, the 6th record for Northamptonshire, appeared at a time of other sightings of this species in the UK, with one visiting four sites in Hampshire later the same day and it, or another (a Swedish-ringed adult) at Saltholme, Cleveland during the evening of 3rd.

Black Tern, Summer Leys LNR, 1st June 2020 (Martin Swannell)

Somewhat overshadowed by the above but in a spring of few records, two Black Terns spent the evening at Summer Leys on 1st. Hopefully more will appear in the autumn.

Northamptonshire’s 6th Caspian Tern shows briefly before heading east.

It was Chris Hubbard’s lucky day as patch persistence paid off this morning with the arrival – and hurried departure – of a Caspian Tern at Stanford Res. Initially glimpsed flying toward the dam, it reappeared almost immediately, flying east over the inlet at around 08.25. Chris was able to grab a series of shots in the 10-15 seconds it was in view before it headed off and away. It was not seen subsequently.

This one follows hot on the heels of the county’s fifth (here), which was seen just under three years ago at Summer Leys LNR on 1st July 2017 before relocating to Clifford Hill GP later the same day. This particular colour-ringed individual ranged widely within the UK, visiting Carmarthenshire, Avon, West Yorkshire, Derbyshire and Buckinghamshire.

Prior to this, previous records were:

Rarity Round-up, 23rd to 29th May 2020

Following a westerly blow on 23rd, the warm, dry weather continued throughout the week, the wind turning easterly for the last two days, as a high pressure system became established over north-west Europe, perhaps raising hopes for just that little bit extra as spring ebbs quickly away.

Last week’s Pink-footed Goose was still at Clifford Hill GP on 27th, as were single drake Garganeys at Stanwick GP from 26th to 28th, at Summer Leys LNR on 27th and 28th (with two there on the first of these dates) and at nearby Wellingborough Embankment, also on 28th. The long-staying drake Red-crested Pochard also continued its presence at Storton’s GP until at least 27th.

Pink-footed Goose, Clifford Hill GP, 24th May 2020 (Adrian Borley)

In an established week for historical rares, the hallowed 29th May (Buff-breasted Sandpiper, Sooty Tern, Bridled Tern, et al) produced nothing in commemoration this year. Nevertheless, there was a fine, summer-plumaged Black-necked Grebe on show at Summer Leys on 25th-26th – bird of the week for many.

Black-necked Grebe, Summer Leys LNR, 26th May 2020 (Mike Alibone)

Black-necked Grebe, Summer Leys LNR, 26th May 2020 (Paul Crotty)

Bitterns are now being seen with increasing frequency outside of the winter season, so one flying west at Stanwick, early on 25th, came as no real surprise. The same site continued to host a single Cattle Egret until at least 24th, while lingering late into the season were single Great Egrets at Stanford Res on 23rd and at both Stanwick and Thrapston GP on 28th.

There was also little change on the raptor front this week, with Ospreys at Thrapston on 25th, 27th and 28th, at Stanford on 26th and at Pitsford Res on 27th, while a male Marsh Harrier visited Harrington AF on 26th. Again, scarce gulls were at a premium, with just an adult Mediterranean Gull at Clifford Hill GP on 24th.

Osprey, Stanford Res, 27th May 2020 (Chris Hubbard)

Osprey, Pitsford Res, 27th May 2020 (Adrian Borley)

Passerines were thin on the ground and included an unseasonal male Stonechat at Clifford Hill GP on 29th. But on 26th, something was brewing in Wellingborough. A house roof, chimney pots, a small flock of Starlings – and a bi-coloured bird looking, well …. decidedly rosy. In the seconds it took to register, realise the potential and grab the camera, it had gone. The exasperation of the moment. The one that got away – an inevitable birding nemesis. A subsequent search of the area drew a blank but to set it in context, it’s not so unlikely. Late May and into June is a prime time for Rose-coloured Starling to occur in the UK and by strange coincidence, the last one in the county was photographed in a Wellingborough garden, almost to the day, on 25th May 2018, during that year’s influx. Said to be larger than that of 2018, another influx is currently underway in Europe, with reported flock sizes of twenty or more reaching Austria a week ago and ‘hundreds’ in France by 28th. With singles on Skomer and in gardens in Essex and West Sussex in the past two days, could this bird have been in the vanguard …?

Rarity Round-up, 16th to 22nd May 2020

A balmy south to south-westerly airstream, a hot, dry week with local temperatures peaking at 26°C … and the county’s tenth Red-footed Falcon. What’s not to like?

Almost as unseasonal as the weather, a Pink-footed Goose showed up at Clifford Hill GP on 21st, although May records are not without precedent. More in keeping with the middle of May, however, were single drake Garganeys at Stanwick GP on 16th and at Summer Leys LNR between 16th and 18th, while the long-staying drake Red-crested Pochard remained at Stortons GP throughout the period.

Red-crested Pochard, Stortons GP, 19th May 2020 (Tony Stanford)

Following last week’s two, another wayward Cattle Egret was mobile around Earls Barton GP on 18th and again, may not have been one of our ‘locals’. Two which most certainly were, though, continued to be seen at Stanwick GP until at least 20th. Seemingly in no hurry to move on, two Great Egrets included singles still at Thrapston GP on 18th-22nd and at Summer Leys on 21st.

The ‘large raptor’ line-up during the period comprised an Osprey at Pitsford Res on 18th and two circling above the A5199 near Hollowell, two days later, on 20th, while single Marsh Harriers flew east over Spratton on 16th and over Summer Leys on 19th. But the early morning stars this week were at least two Common Cranes heard calling at in dawn’s early light, as they moved east of Irthlingborough, on 16th. With continued breeding in East Anglia and the growing population from the reintroduction scheme, The Great Crane Project, in southwest England, it is surprising we do not see more of this species locally.

‘Continental’ Black-tailed Godwit, Summer Leys LNR, 13th May 2020 (Geoff Walker)

On the wader front, the only truly ‘new’ visitors this week were two Whimbrels, which arrived at Boddington Res and then moved to the field opposite the car park there on the morning of 18th. Last week’s nominate race ‘Continental’ Black-tailed Godwit, stayed in the Wader Bay at Summer Leys until 17th and the Wood Sandpiper remained at Ecton SF until at least 16th.

Wood Sandpiper, Ecton SF, 16th May 2020 (Mike Alibone)

Scarce gulls and terns were, unsurprisingly, in short supply at this late stage in the spring but Earls Barton GP mustered an adult Mediterranean Gull on 20th, while a Sandwich Tern spent all of five minutes prospecting Clifford Hill GP’s Main Barrage Lake, before quickly moving on, early on 21st.

First-summer Red-footed Falcon, Ringstead GP, 16th May 2020 (John Friendship-Taylor)

Bird of the week, then? Or perhaps bird of the year, for some? That honour unquestionably fell to the first-summer male Red-footed Falcon which graced Ringstead GP’s Kinewell Lake for four days from 16th. This, the county’s tenth, put on a great display as it hawked low over the water, videoed shearing the surface by the finder, for the greater part of day one, after which it switched to a much higher aerial hunting mode. This bird was part of a handful of records in the UK at the time as the wider European breeding population returned from its African wintering grounds. Click on the map below to see both live and historical movements.

Out of a dearth of passerines emerged just one bird, a ‘Channel’ Wagtail at Boddington Res on 19th-21st. A welcome discovery during a spring in which Yellow Wagtails have been unusually scarce.

Rarity Round-up, 9th to 15th May 2020

The easing of the government’s Coronavirus lockdown restrictions, with regard to travel and ‘exercise’ this week, has resulted in more observers taking to the field and wider local coverage. Birding – with care – is back on …

Mid-May is not a prime time for wildfowl but it’s a great period in which to find one of our most subtly attractive, alluring and scarcest of ducks: Garganey. A pair was found at Stanwick GP on 14th and two superb drakes were on show at Summer Leys LNR the following day. In a more suburban setting, a long-staying drake Red-crested Pochard remained at Stortons GP all week.

The first and so far, only, Quail of the spring was heard singing in a rape field adjacent to Little Morton Sale, east of Apethorpe, on 12th. Monkey business aside, this species was particularly hard to come by last year so, hopefully, there will be more as the spring progresses.

We return to the Nene Valley for an intriguing story of two smart-looking Cattle Egrets, which stayed for just one day at Summer Leys, on 10th. Given that our handful of now resident birds remain site-faithful to the Ditchford/Stanwick area and are not prone to going off-piste, these two gave rise to speculation that they could be ‘new’ birds. Sure enough, thanks to photography and the communication miracle that is social media, it transpired that these two had been making their way slowly north. First spotted at Lavell’s & Lea Farm Lakes NR, Berks, on 25th April, they then spent 6th-8th May at Simpson, Milton Keynes, before arriving at Summer Leys. Well, that’s the theory. At least two were still to be seen at Stanwick on 14th.

Cattle Egret, Summer Leys LNR, 10th May 2020 (Adrian Borley)

Great Egrets have thinned out appreciably since the last round-up and singles were seen at Summer Leys on 10th and 15th and at Pitsford Res on 12th.

And so to raptors … Just one Osprey was reported during the week, fishing at Elinor Trout Lake, Thrapston GP, on 10th, 12th and 13th. A Marsh Harrier flew over Summer Leys on 12th but by far and away the best bird of the week and surely one of the year’s best, too, ducked the Nene Valley action and appeared at Boddington Res on 11th – a superb female Montagu’s Harrier. Quartering fields in the vicinity of the dam, it was present for a good 15 minutes before eventually heading west toward the nearby Warwickshire border. The last one in the county was a male, apparently holding territory near Juniper Hill for two weeks, in May 2008. News of its presence was withheld by the finders at the time. But you have to go back 26 years for the last local twitchable one: a female in the Harrington AF area between 24th and 30th May 1994. There have now been 17 in the county, the first way back in August 1894.

By this time in spring, numbers of passage waders have usually dwindled but a few quality species normally find their way to the county during May. One such bird was at Summer Leys between 13th and 15th. Colloquially known as ‘Continental’ Black-tailed Godwit, this lingering individual was a classic example of limosa, the race breeding in mainland Europe and in very small numbers in the UK, most of the latter being colour-ringed through Project Godwit. Its current status in Northants can only be described as ‘rare’, as just about every Black-tailed Godwit passing through the county – often in flocks – is of the Icelandic race islandica.

Black-tailed Godwit, Summer Leys LNR, 13th May 2020 (Leslie Fox)

Other waders this week included single Whimbrels over Braunston Flood on 11th and at Stanwick GP on 15th, the spring’s sole Sanderling at Clifford Hill GP on 10th and single Wood Sandpipers at Summer Leys LNR on 9th and Ecton SF on 14th. The latter site also produced a Greenshank on these two dates.

One species failing to materialise in any numbers this spring is Black Tern. One was viewed distantly, in windy conditions, off the dam at Hollowell Res on 10th, the same date on which a first-summer Little Gull appeared at Clifford Hill GP.

Although neither scarce nor rare, Hobbies were seen at multiple locations throughout the week but fourteen at Thrapston GP on 15th is noteworthy.

A paucity of passerines resulted in just one Northern Wheatear, near Cransley, on 11th and a White Wagtail at Clifford Hill GP on 10th.

Next week will be exciting …

Ringstead Red-foot

Northamptonshire’s tenth and the first twitchable one since 1997

Right place, right time – the two came together for Nick Parker this morning when he discovered the county’s tenth Red-footed Falcon on a visit to Kinewell Lake at Ringstead Gravel Pits. Found at 10.50, this bird, a first-summer (2nd calendar year) male drew modest numbers of birders throughout the remainder of the day as it put on a fine display, hawking insects among Black-headed Gulls, just above the water’s surface.
