446Yellow Variant House Finch Question
- Oct 30, 2002Can someone tell me the actual reason why some House Finches display not
only the orange variant plumage, but yellow, as well? (See link for a
photo of a yellow variant:
We are discussing the possible reasons on Nature Net's Bird Watching
Forum ( http://nature.gardenweb.com/forums/bird ) and they are running
the gamut from nutritional deficiencies to the age factor. Somehow, I
remember Penny Seaman telling me that George Chaniot or one of the other
ornithologists in this group had read the actual reason, and I would
like to know.
Thanks in Advance,
