Grafham Water - 24 August 2013

A muggy and warm morning with a fresh northerly wind and rain, good conditions for wader and tern movement.


Spent 06.45 to 10.30 covering the dam and fishing lodge areas.

Whimbrel were on the move - 4 were on the dam early morning until pushed off then eventually flew out SW at about 10.00, 6 flew SW at 07.30, a flock of c.18 SW at 09.55 and finally 3 SW at 10.10; 10 Ringed Plovers flew SW and 1 NW; 2 Greenshanks dropped onto the dam briefly before heading off SW; the juvenile Ruff was still on the dam; 2 Snipe flew over and 6 Common Sandpipers were counted. 

Good numbers of terns were present with 16 Black Terns off Marlow early morning then swirled off high west and later 11 Black Terns perhaps part of the same flock were off the lodge; 4 Arctic Terns (1 ad, 3 juveniles) lingered and 4 adults flew straight through south at 08.15; c. 50 Common Terns; 3 Yellow-legged Gulls (3 adults and 1 juvenile).

Notable passerines were limited to a Whinchat at the Yacht Club, c.60 Swallows at the dam and c.80 House Martins over the Yacht Club. 

Later at home 2 adult Sandwich Terns flew south-west along the Great Ouse and 7 Common Terns flew straight through south.
