Brown Blue Tit 04/02/2010

Present KH
Thursday I decided to get among the Siskin and Redpoll Flocks at Hay bridge. A total of 49 birds were processed with 37 new,(retraps in brackets):
Blue Tits 25 (4); Coal Tits 3(1); Great tits 4(7); Blackbird 1(0); Nuthatch 1(0); Redpoll 3(0).

Below are photographs of a Blue Tit? We have some differently coloured tits in the valley. Another Blue Tit was photographed but the subtle difference in plumage was not apparent on the photos.




The brown colouration appeared to come from the lack of the fine barbules on the feathers that hold the blue colouration, notice how my fingers show through on the bottom photograph. Please feel free to comment.
