TUESDAY 26 APRIL
A major change in weather conditions. After record-breaking temperatures in the past two weeks and an extensive ridge of high pressure centred over the UK, a NNE wind changed all that today pegging the temperatures back by at least 15 degrees C and bringing grey skies and considerably colder weather.
Such weather is always productive for hirundines (and normally Arctic Terns) and today was no exception, with the first arrival of COMMON SWIFTS to our area and an upsurge in HOUSE MARTINS......
COLLEGE LAKE BBOWT (BUCKS)
This reserve goes from strength to strength and really has benefited from BBOWT's investment and plans to hallmark it as their premier location. Despite the cold wind, there was plenty to see, especially on the main marsh.
A pair of Great Crested Grebe is now present on the deep pit, with a pair of Mute Swans on the marsh, a pair of Gadwall, 4 Shoveler (3 drakes), 19 Tufted Duck and the continuing pair of COMMON SHELDUCK.
Three families of Lapwing were apparent (adults with 3, 2 & 2 young), the babies being sheltered from the blasting wind, with 6 Common Redshank and a pair of LITTLE RINGED PLOVERS. Two COMMON SANDPIPERS were migrants.
Two Common Terns were investigating the raft, whilst a COMMON CUCKOO was calling from the adjacent Fen, a Common Chiffchaff singing and hirundines again well represented, with 46+ House Martins, 70+ Sand Martins and 15 Barn Swallows.
Pitstone Quarry harboured just 1 lonely Mute Swan.
