Young Carrion Crow

This is a very unusual bird showing extreme plumage abnormalities, possibly caused by stress whilst growing its feathers. This may be caused by lack of food. The flight feathers and coverts of the wing lack pigment although the body feathers would appear to be normal for the juvenile plumage. It is in the process of moulting these and the new feathers are coming through normally. The tail also appears normally coloured. As one generally doesn't see adult birds in this condition I can only assume that when the birds replace their feathers, they come in the normal colour. I see this quite often but this is one of the most extreme examples I have seen.
