Leucistic bald eagle in north west USA
Leucistic eagle spotted on Nooksack River
January 2013. Chris Teren, a wildlife photographer from Washington State in USA recently took these gorgeous photos of a leucistic bald eagle on the Nooksack River in the north of the state. The eagle looks even more attractive than usual with the white patches on his body and wings.
The patches are caused by leucism; 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.
