Leucistic crow in Yorkshire17/09/2008 12:07:46
This picture was taken by Keith Marshall, who has seen it regularly in his garden and the surrounding areas in Yorkshire.
Wildlife Extra thinks this is a leucistic crow, but it seems to be an unusual manifestation. If anyone has another theory, do let us know on the forum.

Leucism (or Leukism)
Leucism is a very unusual condition whereby the pigmentation cells in an animal or bird fail to develop properly. This can result in unusual white patches appearing on the animal, or, more rarely, completely white creatures.
Albinism is a different condition. The easiest way to tell the difference between the two is that in albinism the eyes are usually pink or red, and albinism affects the entire animal, not just patches.
