Hello all! This is my 1st post. My wife and I have been enjoying watching the birds at our feeders for a few years now. This year we have seen birds that we hadnt in the past. So far we have seen Indigo buntings, male and female Rose-Breasted Grossbeaks, Red Headed woodpeckers and Northern Flickers. The bird in question showed up yesterday and we are having trouble identifying it. Any help would be appreciated!!
What you have there is a partial albino Rose-breasted Grosbeak. A genetic mutant where some (but not all!) of the feathers are white, instead of the normal colours. It is a Rose-breasted Grosbeak on the basis of its structure and bill shape.
