I think I'm just just starting to see a common theme to your uploads! Is this purely genetic or the result of mild embryonic damage?

Reduced pigmentation in crows

I think the exact cause can vary.

I believe there is some suggestion that dietary deficiency is the most common cause but whether there is a genetic component to that (i.e. a genetic susceptibility to suffering from dietary deficiency) is not clear.

I've often wondered about the cause. From my observations I think that over the years I've seen similar plumages in the roughly the same locations. But that could be genetic or diet related.

Quite common near me.

This is commonly seen in Carrion Crows in some areas near me, and I know that it has been recorded in crows in other parts of the world (eg. American Crows).
