Whitchurch; c150 European Golden plover next to A413
Granborough hay store; 2 TREE SPARROWS with Chaffinch flock.
Calvert BBOWT; Very large gull pre-roost, thought this might be whole roost but c1,500 large gulls flew from tip straight to sailing lake. Amongst BBOWT flock were 11 adult and a 3rd-winter YELLOW-LEGGED GULL.
Good example of how widely English/ Bucks Gulls range with ringing details from an adult Lesser Black-backed Gull photographed with a colour ring at Calvert recently. It transpired that it was ringed as a juvenile at South Walney Island, Cumbria, in July 1999, then next spotted atPorto de Lgos - Portugal in 2002, Sines - Portugal in 2005 and Calvert - England in 2008
