High pressure and a south to south-westerly airstream saw temperatures move toward the upper twenties during the period, although the week ended on A somewhat damp note as heavy rain moved in from the continent. However, it was the VERY beginning of the week which produced the goods …
And from day one, Clifford Hill GP was, this week, at the forefront, on the 12th topping the locality leader board for the best in class, although that is not seriously applicable to the first of the two – let’s say ‘unusual’ – species found there on that date. During the morning, seven white morph Snow Geese were discovered feeding on the north side of the Main Barrage Lake. It would appear there has never been anything constituting a flock of this species in Northants before … but the date, coupled with the existence of steadily growing numbers of feral birds at Farmoor, Oxfordshire (103 were counted there on 4th May) unequivocally dashes any hopes of their being wild.
There have been a number of flocks seen in the UK over the past six weeks, with forty-two in North Yorkshire, West Yorkshire and Lincolnshire last month and, more recently, thirty-seven moving through Durham, Cleveland, Northumberland and Lothian. Smaller numbers have also appeared in other counties of late. Interestingly, the Northants seven showed up at Eyebrook, Leicestershire the following day and seven, dubbed by BirdGuides as ‘of unknown origin’ (now, there’s a teaser …), were on the Dumbles at Slimbridge on 17th. It seems likely that these were the same birds.
Still on the wild (or not) goose theme, a Pink-footed Goose was in Scaldwell Bay at Pitsford Res on 15th-17th, while the nearby Brampton Valley continued to host a singing male Quail on 16th. The latter date saw the only Great Egret of the week at Stanwick GP and single Ospreys visited Hollowell Res on 12th-13th and Thrapston GP on 14th-15th. Away from breeding sites, single Curlews flew over Stanford Res on 15th and 16th and two Yellow-legged Gulls were at Pitsford on 17th.
Once again, the far east of the county struck gold – this time at Glapthorn Cow Pasture, where three people who had made the journey from Cornwall to see Black Hairstreaks had excellent views of a male Golden Oriole on the morning of 13th. Two lucky local birders, present around the same time, also connected, enjoying brief flight views. Further attempts to find it later in the day, and again early the following morning, unfortunately met with disappointment by the handful of hopefuls searching for it. This bird follows hot on the heels of the male at Fotheringhay on 2nd June.
Fortunately, quite the reverse situation was true when it came to the discovery of the county’s sixth Rose-coloured Starling. Found at Clifford Hill GP on the evening of 12th, it remained until 14th, allowing many to connect with it, although it became increasingly elusive during its 3-day stay. This was the first twitchable one in Northants for twenty-three years and a full account has already been published here.
Arguably no less colourful, last week’s male Channel Wagtail paid a return visit to Stanford Res on the evening of 12th, when it was again around the dam in company with Yellow Wagtails.
Spring, it seems, is not done with yet …
