Warblers 07/07/07

Sedge Warbler - juvenile, immaculate feathers and spotty necklace on upper throat.

Reed Warbler - adult, very pallid individual, worn feathers.

Blackcap - although the cap on this bird appears black it was infact mixed with 40% brown feathers, which combined with its worn primaries and broad and rounded tail feathers made this bird a 1st summer. Closer examination also proved it was a breeder as it had a 'brood patch' - which male Blackcaps have, as they share incubation with the female.

Brood patch.
