LATE SPRING WADER FEAST AT COLLEGE LAKE - WOOD SANDPIPER

THURSDAY 11 JUNE

Some torrential rain fell during the night leaving localised flooding. Once cleared, the day was clear and bright, with clear blue skies and average temperatures.

COLLEGE LAKE BBOWT (BUCKS) (2027-2043)

Following a call from Dave Bilcock informing me of a WOOD SANDPIPER he had just found, I made my way straight there and joined him at 2027. The bird was still showing and feeding with a COMMON GREENSHANK (found earlier in the day by Gareth Luscombe) on the exposed mud in the NE corner of the main marsh. It flew a short way and landed on a miniscule island and proceeded to feed as the light faded. The bird was quite dark in plumage and not in full 'spotting' of breeding attire but had obvious and typically long pale greenish-yellow legs, a very noticeable white supercilium extending behind the eye and rather diffuse brown streaking on the breast. The upperparts were brown with variegated pale spotting, with the uppertail narrowly barred. Both birds were Bucks Year Ticks for me and fairly scarce birds on spring passage. Ian Williams and Roy Hargreaves also connected.

The marsh also held three further species of wader: Lapwings (including 4 chicks), 6 Common Redshanks and an adult OYSTERCATCHER (there was no sign of the other adult and the two small young seen earlier in the week by Rob Andrews). The main island on the lake held at least 8 nesting pairs of Common Tern, with 6 small fledged young waiting to be fed on the edge.
