Participant Photo: albino sparrow?

I saw this bird at the feeder early this morning, and am looking to identify it. I am not able to enlarge it without messing up the resolution, and was hoping someone could identify it. it was the size of a sparrow, but all white except for sparrow colored wings – or similar to goldfinch wings. There was slight blush of grey/brown on head, back and shoulder, with full white belly. Any ideas? it is beautiful, and i’ve never seen it before.
Thank you.
