Unusual Lesser Goldfinch

Recently a male Lesser Goldfinch not showing the usual green and yellow winter plumage has been coming to my backyard. Yesterday my Wingscapes remote camera was waiting for him when he stopped in for a drink. Now the challenge is to determine if this is just a pigment aberration, or if he has a mixed heritage of some kind. I've never seen the black-backed form in winter (they rarely show up in Oregon), so maybe this is just a normal color phase that is out of the normal geographic range.
