Northants birds

In stark contrast to last week’s rush of early spring migrants, blustery north-westerlies, quickly followed by cold north-easterlies, effectively put the lid on any further arrivals of summer visitors. Meanwhile, Thrapston’s long-staying Glossy Ibis remained top of the leaderboard as far as rarities were concerned.

There were no new wildfowl, either – ‘nocmig’ notwithstanding, of course. The two Barnacle Geese which arrived at Pitsford Res last week were still in place on 17th, with another appearing at Summer Leys LNR on the same date. Pitsford also retained its showy drake Greater Scaup off the dam, with the female Greater Scaup x Tufted Duck hybrid in tow, all week, while Ditchford GP’s drake Ring-necked Duck remained until at least 15th, as did the drake and ‘redhead’ Smew there.

Which brings us neatly to this week’s ‘nocmig’ events. The nocturnal equivalent of visible migration watching, employing sound recording equipment to capture the flight calls of migrating birds, is gaining in popularity. After delivering the county’s earliest-ever Little Ringed Plover last week, Scaldwell’s migration station was again tuned in, producing recordings of flocks of migrating Common Scoters during the hours of darkness on 15th and 18th. As we enter the peak season for this species, hopefully there will be some more tangible, ‘on the ground’ birds found during the next week or two.

Arguably best new bird of the week – at least for those who were in the vicinity of Summer Leys on the last day of the period – was Black-necked Grebe. One found on the main lake there during the morning was shortly followed by the discovery of two more over the other side of Mary’s Lane, on the lake of the same name, early in the afternoon. Three of these dapper, summer-plumaged birds in close proximity is unusual but still falls short of matching the recent ‘flock’ of four at Daventry CP in April 2019.

Meanwhile, further down the Nene Valley, last week’s rumours of the Glossy Ibis frequenting the horse field behind the lay-by on the A605 east of Thrapston, morphed into reality when it was found to be feeding happily there on 14th. It remained settled for the next three days, after which it became more elusive.

Also more elusive this week were Cattle Egrets, with sightings at Stanwick limited to one on the ground on 15th and two flying over, two days later, on 17th. And as for Great Egrets, well, they were restricted to just the five localities of Ditchford – where there were potentially up to eight on 17th, Pitsford, Stanford, Summer Leys and Thrapston.

After last week’s Marsh Harrier at Summer Leys, another flew over Byfield on 19th, and then we entered the unidentified raptor zone, with the same day producing a harrier sp. flying north-east over Little Irchester and, potentially more exciting, an eagle sp. flying over Byfield in the direction of Fawsley later in the day. The latter escaped positive identification but was presumed to be a White-tailed Eagle and with the Isle of Wight reintro birds criss-crossing the country in recent weeks, that would seem to be the logical conclusion. Now, that would have been the end of it, except for the fact that, praise be to satellite-tracking … none of the IoW birds was in the area at the time. What with a ‘wild’ White-tailed Eagle moving through Suffolk and Cambridgeshire earlier in the week, speculation is rife …

In terms of species selection, this week’s waders were … last week’s waders. Single Curlews visited Stanford on 14th, Pitsford on 15th and Summer Leys on 15th-16th, while, of two which were present at Clifford Hill GP on 16th, one was multicolour-ringed, the combination of which narrowed it down to one of five or six individuals from the population breeding in the Brecks. This is currently being monitored by the BTO with the aim to better understand how habitat is influencing breeding success and how management may be better targeted to help the species, which is currently in decline. A rather smart, summer-plumaged Icelandic Black-tailed Godwit visited Summer Leys from 14th to 16th and the same site produced a Dunlin on 15th-16th and three on 19th. One also visited Stanwick on 17th. Two Jack Snipes were at Pitsford on 15th and one was found at Ditchford on 17th.

Hot on the heels of last week’s first-winter at Boddington Res came more Kittiwakes and Stanford was in line to receive its own in the well-watched gull roost there on 15th. This was followed by an adult at Stanwick on 16th and sadly, an adult was found dead at Hollowell on 17th. Caspian Gulls made a comeback on 16th, when a first-winter appeared at Daventry CP and a second-winter was found in less salubrious surroundings at Rushon Landfill.

Daventry also produced a couple of Yellow-legged Gulls, with a third-winter on 15th and a second-winter the following day, while up to two were at Pitsford throughout the week. The recent run of Mediterranean Gulls also continued with Stanwick stealing the crown from Stanford in terms of numbers. Three were present on 19th, two on 13th and one on 14th-16th, while Stanford’s gull roost held single adults on 13th and 17th plus a second-winter on 14th. Elsewhere, single adults were at Daventry CP on 15th and Summer Leys on 19th.

On dry land, Harrington Airfield’s Short-eared Owl made it through to another week, being seen again on 16th, when the onsite Merlin was also present until at least 18th. Another Merlin flew north at Boddington Res, also on 16th.

Passerines mustered two Stonechats – one at Harrington on 14th, the other being at Clifford Hill on 18th, while Crossbills held steady with in excess of twenty at Salcey Forest on 16th, several still at Wakerley Great Wood on 14th, three at Hollowell on 15th and one at Pitsford on the same date.

 

This week was very much a tale of two halves, the first of which saw us under a relatively mild southerly airflow that proved to be highly conducive to spring migration. The second half of the period delivered persistently strong to gale force west to south-westerlies, with gusts topping 55 mph but as far as spring migrants were concerned, we were very much in the zone …

The wildfowl line-up didn’t change appreciably and beyond two Barnacle Geese putting in an appearance and settling at Pitsford Res from 6th until 11th, the only really new arrivals were a briefly staying Pink-footed Goose at Daventry CP on 12th, a White-fronted Goose at Priors Hall, Corby, for one day only, on 7th and a drake Greater Scaup, off the dam at the aforementioned reservoir, on 9th.

It was still present at the week’s end, accompanied by a female which showed the hallmarks of a Greater Scaup x Tufted Duck hybrid, although it appeared to display mainly Scaup characteristics. The other hybrid of the back end of this winter – the female Ferruginous Duck x Pochard – surfaced again at Stanwick GP on 8th. The ongoing presence of Ditchford GP’s drake Ring-necked Duck continued until at least 9th, as did that of the drake Smew there, accompanied by the fidgety ‘redhead’ for one day only, on 6th.

Further down the Nene Valley and after a week with no reports, the Glossy Ibis was back on Thrapston GP’s Aldwincle Lake – if only intermittently – on 7th-9th. Prior to this it was rumoured to have been frequenting the horse field behind the lay-by on the A605, just east of Thrapston. Also in the same area, a Cattle Egret was seen in fields between the edge of the town and the footpath from said lay-by to Town Lake during the evening of 11th, before being relocated on the nearby Heronry Lake the following morning. Likely though it is to be one of the Stanwick troop, a new bird can’t be fully ruled out and up to five were still at the latter locality on 6th-7th. Thrapston also trumped all other sites for Great Egrets this week, with up to six there on 11th, while three were at Summer Leys, on and off, and singles were seen at Blatherwycke Lake, Clifford Hill GP, Pitsford, Stanford Res and Stanwick. Arguably more attractive and undoubtedly more difficult to get to grips with than any of the above this week, was the Bittern that dropped into reeds at Summer Leys on 7th.   

Summer Leys also briefly attracted a Marsh Harrier for half an hour on 9th, another Marsh Harrier went through at Stanford Res on 7th and in the north of the county, a ‘ringtail’ Hen Harrier coasted over the road between Deenethorpe and Upper Benefield on 6th.

So, more on that Little Ringed Plover touched on above. A single call on a nocmig recording device, at 00.03 hours on 7th was all it took to make its way into the record books as Northamptonshire’s earliest ever spring record, beating the previous earliest, which was on 10th March 1983. Now, imagine if it had been four seconds earlier … Following this one, another was seen flying around the new workings at Earls Barton GP on 9th.

Single fly-over Curlews occurred at Stanford Res on 6th and 8th and this week, other large waders were also available in the form of Black-tailed Godwits, with singles on 8th and 9th at Pitsford and the same two days at Stanwick, while one which flew over Ecton Brook, Northampton on the morning of 9th seems highly likely to have been the same individual located at Ecton SF later in the day.

Single Dunlins visited Stanwick GP on 9th and 11th and two were at Summer Leys on 10th, while wintering Jack Snipes were up to four at Pitsford and three at Hollowell Res.

Associated with that big south-westerly blow was a first-winter Kittiwake, which joined the gull roost at Boddington Res on 11th. It was not entirely alone as others were also seen well inland in Nottinghamshire, Shropshire, Staffordshire and Warwickshire during the adverse weather.

Mediterranean Gulls continued to appear nightly at Stanford’s gull roost, which peaked at three on 7th, while last week’s Thrapston individual was again seen on 9th and single Yellow-legged Gulls appeared at three sites, which included adults at Hardingstone GP on 8th, Stanford on 12th and at least one at Pitsford all week.

Continuing the poor winter for this species, the Harrington Airfield Short-eared Owl remained until at least 9th.

Well, if last week delivered our first Sand Martin of the year, this week it was the turn of the first Swallow, with two appearing at Clifford Hill on 9th. Once again, these proved to be record-breakers, the previous earliest being a full week later, on 16th March 1977. Wow! It wasn’t quite the same for White Wagtail, though, with this week’s birds at Thrapston and Stanford on 7th, Hollowell on 9th and by the A14 east of Woodford on 12th coming nowhere near the earliest, which was on 25th February 1995.

Another sign that winter is in full retreat was, once again, the lack of Stonechats, with just one being seen, at Welford Res, on 11th. Crossbills still abound, however, with as many as fifteen still at Hollowell on 7th and nine still on 9th, while 6th saw one at Bucknell Wood and two at Scotland Wood, 7th saw three still at Wakerley Great Wood, four flew south over Denton Wood on 8th and two flew south-west over Harrington AF on 12th.

Under the influence of a southerly airstream, the mild weather continued into the early part of the week, bringing with it a waft of Saharan dust which, having entered the atmosphere, resulted in some spectacular sunrises. Along with this came our first summer visitor … and another eagle.

In the first gooseless week since early October last year, we were left with barely a handful of quality quackers propping up the local wildfowl cohort. On which note the drake Ring-necked Duck remained settled on Ditchford GP’s Big Lake throughout the period while, on the adjacent Skew Bridge Lake, the drake Smew also saw the week out, although the accompanying ‘redhead’ appeared to be absent after 27th. Another – or perhaps the same – ‘redhead’ appeared at Summer Leys LNR on 3rd. Colourful but no cigar, a drake Red-crested Pochard was found at Clifford Hill GP on 4th.

Cattle Egrets continued to feature regularly in their favoured Stanwick feeding area but four were also found among sheep on the reserve at Summer Leys on 28th. In stark contrast to last week, Great Egret numbers were down, with no more than three reported at any one of the seven localities they were found at.

Another week, another White-tailed Eagle or, more correctly put, ‘G318’ paid a return visit. After her previous visit last month, the ‘Lady from the Island’ flew west into the county from Buckinghamshire on the afternoon of 3rd and ended up roosting in a small wood approximately 2.5 km south of Grimscote. The following day, she flew 18.5 km south and roosted in Bucknell Wood near Silverstone before leaving the county on 5th and moving 66 km south-west through Oxfordshire. If such a large bird can slip through the county unnoticed, what else are we routinely missing?!

This week saw numbers slide on the wader front, with three Ringed Plovers returning to an undisclosed breeding site on 1st and single fly-over Curlews at DIRFT 3 on 28th and Stanford Res on 4th. Dunlins were limited to singles at both Clifford Hill GP and Stanwick GP on 4th, while the only Jack Snipes were two at Pitsford Res on 3rd.

Conversely – and unsurprisingly – numbers of Mediterranean Gulls ramped up considerably, with Stanford’s gull roost claiming the lion’s share of at least two different birds over 27th, 1st-2nd and 5th. Boddington Res also produced its own duo in the roost there on 28th. Others were more readily available during ‘normal’ daylight hours at Thrapston GP daily on 3rd to 5th, at Earls Barton GP on 3rd, at Stanwick on 4th and Daventry the following day. Again, all birds were adults. Rushton Landfill’s long-staying juvenile Iceland Gull chalked up twenty-eight days on site this week, still being present there on 4th, while more meaty fare in the shape of a first-winter Caspian Gull was at DIRFT 3’s A5 Pool on 28th and single Yellow-legged Gulls were seen at Pitsford on 2nd and 5th.

The Harrington Airfield Short-eared Owl – one of the very few in the county this winter – remained throughout the week but it’s proving to be a good one for Merlins, this week’s comprising singles at both Rockingham and Upper Benefield on 1st and Pitsford Res on 3rd.

Topping the passerines, the male Bearded Tit resurfaced at Stortons GP on 28th and fittingly, out of that Saharan dust, came our first Sand Martin of the year, at Summer Leys on 3rd. Otherwise, it appears numbers of Stonechats plummeted this week – Pitsford being the only site from which they were reported. But we’re hanging on to our Crossbills, with as many as ten still at Hollowell throughout the period and fifteen still at Wakerley Great Wood on 5th.

A south to south-westerly airstream ensured temperatures remained above average throughout the period. This week the spotlight remained firmly on Thrapston.

Barnacle Geese came to the fore in this week’s wildfowl line-up, with nine at Stanwick GP, apparently replacing the White-fronted Geese there on 23rd. In fact, the only White-fronts during the period were two in flight over Byfield on 20th, while single Pink-footed Geese were at both Ringstead GP and Stanwick on 20th.

Stanwick was also paid another visit by the itinerant female Ferruginous Duck x Pochard hybrid on 21st, the day on which the drake Ring-necked Duck was refound back on Ditchford GP’s Big Lake, where it was still present at the week’s end. Paralleling this, last week’s two Smews at the same locality also re-emerged on Higham Lake on 23rd and on the same date, a new ‘redhead’ was discovered on Thrapston GP’s Aldwincle Lake, where it, too, remained until the end of the week.

Looking set to see the winter out, Pitsford’s juvenile Great Northern Diver stayed mobile between the causeway and the dam there until at least 23rd.

The focus of attention remained, however, on Thrapston’s Glossy Ibis, having abandoned its regular haunt of Islip Water Meadows in favour of Aldwincle Lake, where it appeared settled throughout the week, mercifully free of human disturbance.

Thrapston’s purple patch continued with the appearance, albeit briefly, of a Cattle Egret on 21st – seemingly the first record for this locality while, further up the valley, up to three remained at the usual Stanwick stronghold.

Back at Thrapston, a milestone was reached this week in the shape of a single-site, double-figure count of Great Egrets, with a likely ten there on 25th. So it looks very much like the county’s wintering population is now twenty plus, the majority of which are in the Nene Valley. Common as muck, as they say …

No so common and, in reality, at the other end of the scale, a White-tailed Eagle was seen drifting high over the Boughton Estate, north of Kettering, on 21st. With those from the Isle of Wight reintroduction scheme floating around off the leash, it might not ordinarily have raised too many eyebrows but we have it on good authority that all the satellite-tagged birds were accounted for elsewhere. Boom! Somewhat overshadowed, under the circumstances, was a Marsh Harrier, which passed through almost unnoticed, at Stanford Res on 20th.

Numbers held up on the wader front this week, with Stanwick’s Bar-tailed Godwit continuing to occupy the prime slot until at least 22nd, while new in was a Black-tailed Godwit at Summer Leys LNR on 21st. Also new were single Curlews at Stanford Res on 21st, Lilbourne Meadows on 22nd and at Clifford Hill GP on 25th, while numbers of Dunlins again fell to just four at the DIRFT 3 development area and 2 at Stanwick GP – all on 21st. Only two localities hosted Jack Snipes with possibly up to eight present in suitable habitat near Ravensthorpe – again on 21st – and up to four at Hollowell between 23rd and 26th.

With only a few more days to go until March, the prime spring month for the movement of Mediterranean Gulls, a few have already started coming through. Stanford’s gull roost held two on 24th and 26th, while the second of these two dates saw one in a gathering of gulls at Hollowell during the last hour of daylight. All birds were adults. By contrast, a young bird with nowhere to go anytime soon was the juvenile Iceland Gull at Rushton Landfill, which remained there throughout the period.

This week’s Yellow-legged Gulls were all adults, with singles seen at Ditchford GP on 20th and sporadically throughout at Pitsford, plus four at Hollowell on 26th.

The 23rd saw Merlins at Sutton Bassett and Harrington AF while, on the passerine front, Stonechats were found at ten sites this week, with no more than three at any one of these.

Although it’s late February and Crossbills should be breeding, it appears we still have flocks locally, with up to twenty at Wakerley Great Wood on 25th-26th and up to fifteen still at Hollowell between 21st and 26th. Maybe our birds are from further north …

This week, the meteorological pendulum swung in the opposite direction and almost at the flick of a switch, temperatures soared from well below, to significantly above, average. South-westerlies were back and the ice melted as one celebrity bird ended the long wait for many local birders to catch up with it in the county.

But first things first and new on the scene this week were more Pink-footed Geese – one at Stanwick GP from 13th until at least 17th and two just along the valley near Ringstead GP on 17th with at least one remaining until 19th. Back at Stanwick, the wintering White-fronted Geese topped thirty-three – a highly respectable total for the county in recent years.

All the pizzazz exuded by Ditchford’s glitzy drake Ring-necked Duck quickly evaporated as it seemingly vanished after 14th, the date it was last seen on Higham Lake. It might just be that no one has looked since, of course. Perhaps the same could be said about the two Smews at the same locality – the ‘redhead’ not having been seen since the day it was found and the drake coincidentally appearing to do a bunk after 14th. What is it about Valentine’s Day?

Perhaps the drake making a brief appearance in Pitsford’s Holcot Bay on 16th was the same bird. Some consolation was subsequently provided by a bevy of three ‘redheads’ which turned up at Ravensthorpe Res on 13th, remaining there until 15th, after which only one appeared to be present the following day. Across the road, at Hollowell Res, a female Greater Scaup was discovered on 14th, remaining there until the week’s end.

Meanwhile, fast fading into the background was Pitsford’s juvenile Great Northern Diver, which was reported only on the first day of the period.

In a bizarre and unexpected turn of events, however, it was a species hitherto notoriously difficult to catch up with locally that stole the limelight this week. After multiples in neighboring Cambridgeshire and a roving bird in Bedfordshire this winter, a Glossy Ibis finally found its way into Northants. First seen flying south over Thrapston GP on 13th it was subsequently discovered three days later on Islip Water Meadows, only a stone’s throw from where it had originally been seen in flight. Providing respectable views from the track running down the western flank of Thrapston’s Town Lake and from Islip’s Mill Lane, unlike the previous six seen in the county, it did the decent thing and settled there throughout the remainder of the week, allowing many a local to catch up with it. Hopefully, it has now dug in for the rest of the winter.

First-winter Glossy Ibis, Islip Water Meadows, 18th February 2021 (Mike Alibone)

Undoubtedly overshadowed by the above, just two Cattle Egrets were reported, not a million miles away, at this species’ favoured location of Stanwick on 13th. Nine wetland localities produced between one and four Great Egrets apiece this week with, once again, Summer Leys LNR laying claim to the lion’s share of seven on 13th. A Bittern was reported from Thrapston on 19th.

Some of last week’s hard weather waders remained in the county throughout the period, most notably Stanwick’s Bar-tailed Godwit, which crossed the A6 to visit Irthlingborough Lakes and Meadows LNR on 16th before returning to Stanwick to see out the remainder of the week. A single Knot further contributed to putting Islip Water Meadows firmly on the map during its brief visit on 13th, while Dunlins maintained a presence of sorts, with lower numbers this week including up to four at Stanwick and Clifford Hill GP, three at Earls Barton GP and one at Pitsford. Only to be expected were Jack Snipes at the usual locality of Hollowell, where there were up to three and at the less renowned sites of Wicksteed Water Meadows, Kettering – again with three and two at Clifford Hill GP.

Apart from an adult Yellow-legged Gull at Pitsford on 16th-17th, a gull with ‘form and history’ visited Stanford Res on 13th, identifying itself to observers as a Polish-ringed, first-winter Caspian Gull by way of its decorative legwear. Yellow ring, number P:PW6, enabled its movements to be followed since being ringed as a nestling at Mazowieckie, Poland on 16th May 2020. On 12th December 2020, it visited Zeeland in The Netherlands, subsequently crossing the North Sea to appear at Tanholt Landfill, Peterborough on 26th January 2021, before being seen again at Shawell Landfill in Leicestershire on 5th February – a distance of 1522 km from its Polish colony.

On dry land, last week’s Short-eared Owl remained at Harrington AF throughout and another was seen nearby, in the Brampton Valley, on 14th, while a female Merlin was at Harrington on 13th.

Stonechats were found at eight sites this week, with Hollowell producing the highest count of six between 16th and 19th, as well as solely accounting for this week’s Crossbills the highest number of which was eight or nine on 13th.

That would be it, other than for the fact that we now know the first summer visitors have arrived in the UK this week, with South Wales producing the first Northern Wheatear and Sand Martin, Dorset seeing the country’s first Swallow and the first Ring Ouzel appearing in Devon. Dare we hope the forthcoming week will deliver at least one early migrant to our own county … ?

From some way beyond Scandinavia, cold Arctic air on the back of so-called ‘Storm Darcy’ delivered little more than a sprinkling of snow during a week in which daytime temperatures reached a low of -3°C. Factor in the wind chill and you were down to -8°C. Associated with these conditions there was also a sprinkling of rather unseasonal waders, along with the discovery of the county’s 9th record of Ring-necked Duck. Other ducks were also available …

And so were geese, with another sizeable flock of Barnacles – this time twenty-four – appearing on land adjacent to Boddington Res on 11th. The same winter gaggle of at least twenty-nine White-fronted Geese continued to find Stanwick GP to their liking, remaining on, and around, the site all week.

Meanwhile, some observers were treated to a white-out at Stanford Res, where eighteen Bewick’s Swans were discovered early on 6th. Seemingly ‘grounded’ in foggy conditions, they were off as soon as the mist cleared, being seen minutes later flying north-east over nearby Sulby. Interestingly, at least two of these birds were identified from the Stanford photos (on bill pattern) as having recently left their wintering grounds at WWT Slimbridge in Gloucestershire, setting out on the long journey back to their breeding area. However, they seemingly aborted their migration in the face of adverse weather conditions and returned to Slimbridge shortly afterward. More Bewick’s were subsequently logged in the area, with five south-west over Sulby on 11th and two over, north-east, on 12th, when five also flew east over the Brampton Valley Way between Clipston and Arthingworth.

Quickly glossing over the appearance of the female Ferruginous Duck x Pochard hybrid again at Stanwick on 8th, the focus this week was on the discovery of a fine drake Ring-necked Duck at Ditchford GP on 6th. Mobile between Big Lake and Skew Bridge Lake, it remained until the morning of 12th, after which it promptly did a bunk. To set this occurrence in context, we are in the midst of a sizeable influx, this winter having so far seen almost forty birds across the UK and Eire, with multiples of up to four to be found at some sites.

 

Vagrants aside – no matter how smart they might be – no winter is complete without that final vital ingredient – a drake Smew. The first one this side of the New Year again put Ditchford firmly on the map, being found on 11th, along with a ‘redhead’, both birds being independently mobile throughout the day before teaming up on Delta Lake at dusk. Neither was seen subsequently.

Demonstratively more dependable, though eliciting seemingly less interest, Pitsford’s juvenile Great Northern Diver remained all week, as did up to three Cattle Egrets at Stanwick. Four localities – Ditchford, Stanford, Stanwick and Thrapston GP – produced between one and two Great Egrets apiece, while Summer Leys LNR notched up at least five on 12th.

Perhaps an indication of just how severe the freezing conditions have been this week was the arrival in the county of a number of waders which would normally be found wintering in coastal locations. Hard weather movements resulted in the unseasonal appearance of a Ringed Plover at Willowbrook Industrial Estate in Corby on 7th, a Bar-tailed Godwit, which remained at Stanwick from 9th until the week’s end and Knots at four localities.

The latter included a flock of thirteen flying NNE over Byfield on 8th, three on floodwater by the River Cherwell near Kings Sutton on the same date, one at Stanwick GP on 9th and one by the River Welland, south of Gretton, from 8th to 10th. This last bird was accompanied by around thirty Dunlins, dropping to about twenty over the following two days. This is an exceptional number in modern-day Northamptonshire – especially in winter! There were more. Five near Kings Sutton and singles at Ditchford GP and Pitsford Res on 8th, up to three at Stanwick between 9th and 12th, five on floods near Barnwell on 10th and two at Summer Leys on the same date. More in season were Jack Snipes, with singles at Hollowell on 6th, Stanford on 7th and Clifford Hill GP on 12th.

Meanwhile, scarce gulls remained just that, with two adult Mediterranean Gulls in the roost at Stanford on 12th, the juvenile Iceland Gull seemingly settled at Rushton Landfill all week and an adult Caspian Gull there on 7th.

‘Scarce’ is also undoubtedly applicable to Short-eared Owls this winter, one of which was seen this week at Harrington AF, on 6th. Surely Northants can do better than this? Two Merlins comprised single females in flight at Pitsford on 10th and Boddington the following day.

Stonechats were present in the Brampton Valley and at Hollowell and Stanford, while after a week with no reports, Crossbills were back, with up to five at Harlestone Heath between 8th and 10th and between five and ten at Hollowell on 9th.

Chilly east to north-easterlies kept temperatures depressed in the first half of the period, after which a mild spell saw a double-figure rise to 11°C, under the influence of a south to south-westerly airstream. The week’s focus was centred firmly on the presence of two White-tailed Eagles, the anticipated easy connectivity with one giving rise to a small, though appreciable, stream of ‘local’ birders to its favoured wetland site.

It was, however, a poor week for wildfowl by recent standards with the thirty or so White-fronted Geese remaining around their chosen fields at the northern extremity of the Stanwick GP complex until at least 2nd and the female Ruddy Shelduck enjoying an away-day at Foxholes Fisheries, Crick on the same date. The infamous female Ferruginous Duck x Pochard hybrid again materialised at Stanwick on 31st, remaining in the area until at least 3rd. In terms of its physical appearance it looks almost the real deal – close but no cigar.

The juvenile Great Northern Diver remained loyal to Pitsford Res all week and, keeping a low profile, between one and three Cattle Egrets were seen at Stanwick GP throughout, while three were on fields immediately south of Irthlingborough on 31st. A rather modest number of Great Egrets was logged, with up to three at Stanwick and singles at Ditchford GP (IL&M), Hollowell Res, Pitsford, Ringstead GP, Stanford Res and Stortons GP.

This week, the county played host to no less than two immature White-tailed Eagles from the Isle of White introduction scheme, their paths almost crossing near Pitsford Res on 1st. Their movements are documented here. Despite not being ‘fully wild’, their majesty, grandeur and sheer enormity were more than enough to captivate, interest, and inspire a number of local birders to make the interpreted ‘permitted short journey to exercise’ at Pitsford to connect with the lingering male, on 31st. He departed to Oxfordshire the following day, when the female arrived, this second bird remaining in the county until moving into Cambridgeshire on 3rd.

Waders’ sole representative this week was a Jack Snipe at Hollowell on 30th-31st but gulls rallied somewhat, with an adult Mediterranean Gull in the roost at Stanford on 4th, followed the next day by a juvenile Iceland Gull at Rushton Landfill – only the second of the winter so far, the previous one having also been found at the same site. Two adult Caspian Gulls were also present there on 5th and another adult visited Hollowell on the same date, while single adult Yellow-legged Gulls visited Daventry CP on 1st, Pitsford on 2nd and Hollowell on 5th.

Juvenile Iceland Gull, Rushton Landfill, 5th February 2021 (Mike Alibone)

Although passerines were poorly represented during the period, suburban Northampton was still delivering the goods in the shape of at least one Bearded Tit, a male, at Stortons GP, where it popped up again in the reedbed on 4th.

Otherwise, Stonechats continued to delight at Hollowell, Pitsford, Raunds, Stanford, Summer Leys and Sywell CP, with no more than three at any one locality.
