Hey Tweets...

I have seen a crow with what looks like 3 white primaries..it's hard to tell
when it flies off, but it looks as though the last feather on each side of
the tail is also white. This particular crow has appeared in my yard feeding
on chicken scratch and sunflower seeds I throw out for the crows and ducks.
It is "normal" in all other aspects except for the few white feathers.

Can someone explain what causes this (I am assuming) genetic abnormality?

Thanks in advance...
