Seen nothing like this...
Alan Gilbertson sent me this photo today of a strange lemon and white bird taken in a garden in Widdrington.
His frist guess was an albino Chaffinch but then changed his mind to Canary. A reasonable enough assumption. I mean a Chaffy with lemon and white colouration? Never.
Look closer though.
Bill - Long and pointed. Canary has short and conical, regadless of type.
Head - Square naped witha hint of crest. There is a demarcation line between the lemon back and the paler nape shadowing that of the normal bird above.
Wing structure - Primary length actual and in relation to tertial length fits. Canaries generally have a shorter wing.
Rump - Flight shots show the pale bird to have a yellow rump in the same position a normal Chaffinch would be bright green.
And what the photo doesnt show is that this bird has been around now for two winters, I havent known an escaped canary last more than a week! ( I used to breed them when I was younger).
Alans first impressions were right, this is a leucisitc Chaffinch.
A hunt on Google images for leucisitic chaffich showed a few examples but none as extreme as this one....
Here are few more images...
