A couple of posts ago I asked for opinions on a bird coming to my backyard feeder here in Minnesota. The majority of opinions were that I was being visited by an aberrant House Finch.
Well it's still around and I got a better look at it.
So the question today is not about species (unless someone has a better ID), the question is about the mechanism of the strange feather color. I assume something genetic but not albinism. Whatever the cause it seems the bird is in good health, has been present for a while and doesn't seem to mind the snow.
Pretty fun having this bird around. Now if I could just coax that Lewis' Woodpecker in Wisconsin over to my suet feeder...
