Month: March 2015

A stiff east-northeasterly breeze ensured a cold start to the week, which then remained chilly but largely dry and bright. Early common migrants began to appear in some numbers including more Sand Martins and a noticeable large wave of Chiffchaffs, while some of our less common winter visitors maintained a presence.

Falling into the latter category the three European White-fronted Geese were still at Pitsford Res until at least 18th and the two Ruddy Shelducks – now sporadic in their appearances – were still at the same site on 15th. The drake Pintail also remained at Summer Leys LNR until at least 18th, as did the drake Red-crested Pochard at Stanford Res, while two were found at Sywell CP on 16th. The long-staying female Ring-necked Duck was still at Billing GP until at least 18th as were two Smew at Ravensthorpe Res and a ‘redhead’ at Stanwick GP on 20th.

The two Great White Egrets remained at Summer Leys until 15th with one there until 20th, while two were found at Ditchford GP on 16th while the best on the raptor front was a ‘ringtail’ Hen Harrier hunting by the concrete track at Harrington AF on 19th and single Peregrines at Old Sulehay on 15th and Ditchford GP the following day.

Golden Plover records were restricted to the Brampton Valley, Harrington AF and Scaldwell with a maximum of one hundred and twenty-five at the latter locality on 14th – the same date that the first Ringed Plover of the spring was photographed at Earls Barton GP. A Curlew was in the Tove Valley on 18th-19th, Common Snipe were found at Brixworth STW, Stanford Res and Summer Leys, while eleven were counted on 14th at Hollowell Res, which also produced a Jack Snipe on the same date. Other waders included one to three Redshanks at Clifford Hill GP and Summer Leys and a Green Sandpiper at Stanford Res on 18th. This week saw rather more in the way of quality Larids. The gull roost at Boddington Res again produced adult Mediterranean Gulls on 16th and 18th as did Pitsford Res on 14th and 15th and further singles visited Daventry CP on 17th and Summer Leys the following day. The best, however, was an adult Iceland Gull in the Pitsford Res roost on 14th, followed by a second-winter Caspian Gull there on 18th, while the only other gulls of note were two adult Yellow-legged Gulls at Hollowell Res on 14th and a third-winter in the Pitsford Res roost on 17th.

Last week’s first-winter Waxwing remained in Corby until 15th and, arguably not in the same league, a Rock Pipit was found at Boddington Res on 16th and a Water Pipit at Summer Leys on 18th. Four Stonechats were still at Blueberry Farm on 14th and the first Northern Wheatears of the year were at Clifford Hill GP and Blueberry Farm (Maidwell) on 18th followed by singles at Harrington AF and in the nearby Brampton Valley the next day.

What a difference a week makes! South-westerlies, rising temperatures and largely mild conditions created ideal conditions for the northward movement of the first summer migrants into the UK, with Northants receiving at least a sprinkling. Other birds were also plainly on the move – a clear indication that spring migration is now well and truly underway.

They should surely have been on their way by now but the three European White-fronted Geese were still at Pitsford Res until at least 11th with the two Ruddy Shelducks remaining there on 7th. A drake Pintail was again at Summer Leys LNR on 7th-8th and the drake Red-crested Pochard remained at Stanford Res over the same two days, while the female Ring-necked Duck – after going unreported last week – was still at Billing GP until at least 11th.

If we hadn’t enjoyed the generous helpings of wintering Long-tailed Ducks last year then the first-winter drake which paid a brief visit to Pitsford Res on its way north on 10th would perhaps have elicited more interest than it actually did; this species is still a rare visitor to the county on any account. Most of our wintering Smew have departed and those remaining this week included two at Pitsford Res on 7th, a ‘redhead’ at Stanwick GP on 10th and 11th, the two ‘redheads’ still at Stortons GP on the latter of these two dates and three at Ravensthorpe Res on 13th.

The only Great White Egrets to be found during the period were the Summer Leys duo, which remained until at least 12th. And then there was ‘Klio’. The name given to the White Stork which, having escaped from the Exotic Pet Refuge near Deeping St James last week, appeared in Northants by the River Nene near Nassington on 7th and then border-hopped to various sites in nearby Cambridgeshire the following day. On 11th ‘he’ was back – this time at Ditchford GP’s Irthlingborough Lakes and Meadows Reserve for an hour or two before flying to Brigstock and finally Lowick, where he was eventually recaptured on 12th. A smart bird with no rings which would surely have passed muster had its origin remained unknown …

A grebe found on the main lake at Stanwick GP on 8th ultimately proved to be a Slavonian Grebe after giving rise to some debate over its initial identification as a Red-necked. It was not present the following day so this was another bird which had moved swiftly on. It, or another, was found at Ravensthorpe Res on 13th.

And so to the vanguard of our summer visitors. An Osprey moved north over Harrington AF on 10th, no doubt the first of many to come, while Peregrines at Greens Norton on 7th and at both Stanwick GP and Summer Leys on 13th, and single Merlins at both Daventry CP and Blueberry Farm on the latter date were the only other raptors reported during the week.

Golden Plovers were recorded from Harrington AF, Byfield, Bozenham Mill and Blueberry Farm (Maidwell) with a maximum of three hundred at the latter site on 10th. This has been a poor winter for this species with no four-figure counts anywhere. A Curlew visited Clifford Hill GP on 8th, Common Snipe were found at Blueberry Farm, Bozenham Mill, Stanwick GP and Pitsford Res, with a maximum of thirty-four at the latter locality on 11th, which also produced two Jack Snipe on the same date. After last week’s double-figure count at Stanwick GP, Redshanks appeared to be unduly scarce with just one at Clifford Hill GP on 7th, two at Summer Leys the following day and up to four there on 13th, while single Green Sandpipers were found at Stanford Res on 7th and 8th, Pitsford Res on 7th and 11th, at Upton Valley (Northampton) on 10th and between Everdon and Fawsley on 13h.

The gull roost at Boddington Res is consistently the most reliable site in the county for passage Mediterranean Gulls when they come through in March. This week saw three adults there on 9th, two adults and a second-winter on 10th and an adult on 11th. No doubt more will be seen there as the month progresses. The only other gulls of note were an adult Yellow-legged Gull in the Pitsford Res roost on 12th and three at Hollowell Res on 13th.

Rather more scarce this winter, a Short-eared Owl was at Blueberry Farm on 7th and again on 13th; other than passage birds it seems unlikely this species will be seen in any numbers now before next autumn. The same cannot be said for Sand Martin, the first of which appeared at Ditchford GP’s Broadholme SWT on 9th – arguably the first true summer migrant of the year, Chiffchaffs notwithstanding, of course, this week appearing to herald an arrival en masse with records from nine widely-scattered localities. Presumed Central European Blackcaps – it’s still a bit early for the return of Iberian winterers – were a female in a Wellingborough garden on 8th and a male in a garden in Barton Seagrave on 11th.

The main attraction on the passerine front this week, however, was the first-winter Waxwing which was found in Corby on 11th and remained, posing for the cameras, until 13th.

Up to six Stonechats were still at Blueberry Farm all week and singles were also at Pitsford Res and Stanford Res on 7th.

Bland and generally flat. Another treacle week in which long-stayers stuck, with not even the sniff of a Sand Martin on the rising temperatures to lift the spring spirits.

A ‘new’ Pink-footed Goose was found at Thrapston GP on 4th and the Ravensthorpe Res individual was present again on 6th, while the three European White-fronted Geese continued to stick it out with the two Ruddy Shelducks at Pitsford Res, now becoming disconcertingly tame on the waterline along the dam.

Eight Barnacle Geese which dropped into Stanwick GP briefly on 28th were surely from feral stock but you never know … Just one Red-crested Pochard was reported this week – a drake at Stanford Res on 1st and the only Smew were five still at Ravensthorpe Res on 28th, falling to three there on 6th, and two – both drakes – at Stanwick GP the following day.

Up to two Great White Egrets remained at Summer Leys LNR all week and singles were at Ditchford GP on 3rd and at Stanwick GP the next day. The only raptor of note was a Peregrine at Hollowell Res on 6th.

Few waders were reported with just one Golden Plover in flight over Ravensthorpe Res on 28th and thirty near Hanging Houghton on 6th, single Common Snipe at Hollowell Res and Stanford Res on the same date with another at Harringworth AF and at least fifteen at Stanwick GP the following day. The first day of March also saw twelve Redshanks at the latter locality, when there was also a Green Sandpiper at Stanford Res, followed by another at Pitsford Res on 2nd and another at Lower Benefield on 4th.

The gull roosts of Pitsford and Boddington Reservoirs produced single adult Mediterranean Gulls on 2nd and 5th respectively and another was at Hollowell Res on 6th, while two adult Yellow-legged Gulls were again at Hollowell Res on 28th and another visited Stanford Res on the same date.

The only Chiffchaff this week was one, also at Stanford Res on 28th, and the only Central European Blackcap, a male, frequented a garden in East Hunsbury (Northampton) until at least 4th. Other wintering passerines included the up to three Stonechats at Hollowell Res, five in the wider Maidwell Vale and one at Pitsford Res and

a male Brambling – scarce this winter – near Burn Coppice (Deenethorpe) on 1st with another flying east over Hollowell Res on 6th.
