Although local temperatures reached only 22°C, the 30th hit the headlines as the UK’s warmest March day for 53 years, largely as a result of south to south-westerly winds sweeping in from beyond the Iberian peninsula. Unsurprisingly, spring migrants came in thick and fast, these balmy conditions acting as a catalyst for northbound migration. It was all change during the last two days of the week, however, as winter reminded us it was not done with yet, bitter north-easterlies kicked in and temperatures dropped like a stone …
Showing no signs of going anywhere soon, the adult Dark-bellied Brent Goose remained at Ditchford GP’s Irthlingborough Lakes and Meadows LNR throughout the period, while new in was a Pink-footed Goose, which flew west over Ecton SF on 1st before dropping in to join local Greylags in the adjacent riverside meadow at Cogenhoe Mill.
The same date saw the arrival of the year’s first Garganey, at Clifford Hill GP, where four pitched up during the morning, appearing to have moved swiftly on by the end of the day.
Meanwhile, the wintering drake Ring-necked Duck showed further signs of itchy feet this week, appearing again at Stanwick GP on 27th-28th and 30th before heading west to Clifford Hill, where it was seen on 31st and again on 2nd.
In contrast, the smart drake Greater Scaup, accompanied the presumed female Greater Scaup x Tufted Duck hybrid, remained site faithful, off the dam at Pitsford Res all week while, back in the Nene Valley, Ditchford GP’s drake Smew resurfaced on Delta Pit on 27th before being seen at Stanwick the following day and again there on 2nd.
Ditchford also produced a one-day wonder in the shape of a flamboyant, summer-plumaged Black-necked Grebe at Irthlingborough Lakes & Meadows on 31st.
Further down the valley, with no departure date in sight, the local star that is Glossy Ibis clocked up eight weeks of residency at Thrapston GP, spending more of its time on Aldwincle Lake. It will be missed when it finally chooses to move on, although after such a long stay, this species is never likely to be viewed in quite the same light when the next one hits the county.
Talking of which … four Cattle Egrets remained at the favoured locality of Stanwick on 27th-28th, while numbers of Great Egrets continued to decrease, with singles at Summer Leys on 28th and Hollowell on 30th, up to two at Pitsford on 31st-1st and up to five at Thrapston on 31st.
With Ospreys back in the game, singles were seen at Billing GP, Hollowell, Pitsford and Ravensthorpe Res – all on 27th, Ravensthorpe again on 29th, Oundle on 1st and Hollowell Res again on 1st-2nd. Three pairs have bred in the county over the past few years and with numbers increasing nationally, we must be on for a fourth in the not too distant future. Two single Marsh Harriers flew east through Stanwick, within minutes of each other, on 2nd.
On the wader front, two Avocets were mobile between Summer Leys and Ditchford GP’s Irthlingborough Lakes and Meadows LNR throughout the week, while single Curlews flew over Stanford Res on 27th, Pitsford on 1st and two worked their way from Ditchford along to Stanwick on 2nd. Last week’s first-summer Black-tailed Godwit remained at Summer Leys until 28th, being replaced there by three from 31st to 2nd. Three also visited Stanwick on 31st.
With only singles at Clifford Hill on 30th and DIRFT 3 A5 Pools on 1st, Dunlins were thin on the ground this week. A Jack Snipe remained at Hollowell until at least 30th, the same date on which one was found by chance at Harrington AF.
Pumping up the larid-action, there were gulls for everyone this week – after all, who doesn’t love a Little Gull? One of these delicate, diminutive beauties visited Daventry CP on 31st and another obliged by staying two days at Thrapston on 1st and 2nd. The last of these two dates also saw a first-winter Kittiwake heading south-west over Pitsford, apparently without stopping. Mediterranean Gulls were again largely confined to the two Nene Valley locations of Stanwick and Summer Leys, where they continued to be seen almost daily, the latter site holding three on 29th. The exception was two adults seen south of Burton Latimer, on 27th. The week’s token Caspian Gull, a first-winter, appeared on DIRFT 3’s A5 Pools on 1st, accompanied by another, which wasn’t quite the full shilling in terms of genetic make up, as well as one each of both adult and third-winter Yellow-legged Gulls. Two of the latter species also frequented Pitsford during the week.
Then the summer visitors kicked in. Two Sandwich Terns flew east through Stanford on 31st, followed by two more, east through Stanwick, the following day.
But the first Hobby, on 30th, smashed it, being the first ever to be recorded in March and beating the previous earliest record of 1st April, in 2012.
The first Willow Warbler was a male singing in suburban Northampton on 28th, followed later by one in Corby and, just before the month of March was out, the first Common Redstart appeared on Borough Hill with, hot on its heels, another at Harrington. Both were males. Following last week’s Black Redstart, three more were reported: Harrington AF on 30th, Hanging Houghton on 1st and Borough Hill on 2nd – all strangely vanishing immediately after their discovery. A Stonechat at Summer Leys on 28th was effectively the last man standing.
Unsurprisingly, more Northern Wheatears appeared this week, with the eight localities of Brackley, Chelveston AF, Clifford Hill, Harrington, Hinton AF, Polebrook AF, Stanford and Thrapston producing a couple of dozen between them. The highest counts were nine at Hinton on 29th and five at Clifford Hill GP on the same date.
Clifford Hill also delivered the first Yellow Wagtail of the year, on 1st, two more being seen at Stanwick later in the day, while White Wagtails continued to come through in small numbers, with Earls Barton producing one on 27th and two on 2nd, while another was at Aldwincle on 1st.
A brief stopover was made by a Water Pipit at Hollowell on 30th before it flew off south. In fact, as Water Pipit must be the only species flying south in spring, this surely constitutes the identification clincher from the often very similarly-plumaged Scandinavian Rock Pipit which, of course, flies north-east. Simple, isn’t it?! The answer was there all along! Well, maybe … Two more Water Pipits were at Earls Barton GP’s new workings on 2nd.
Caught on film at Wakerley Great Wood, a Mealy Redpoll visited the feeders there on 2nd, when there were still at least four Crossbills in the same area.
Ten were counted there on 29th, while the only other localities continuing to produce this species were Hollowell, with a maximum of five on 27th and Pitsford, where up to four were present on 31st.
