This leucistic white raven (not albino) was perched near the top of a very tall fir tree quite far away. It was perched amongst the branches to prevent other ravens from attacking it. As soon as it took flight, it was chased around by several ravens and forced out of the area. I am not aware if the black ravens would actually kill it.
In this part of the central east coast of Vancouver Island there are several ravens that carry the recessive gene that results in two normal black ravens having one or more white leucistic young. It seems the parents and siblings will accept the white ravens until they reach a certain age. They then become 'raven outcasts' and are forced out of the family and flocks. As such, they must learn to live a solitary existence and are unlikely to ever find a mate.
