|Leucistic American Goldfinch, Needham, MA|
I actually haven't seen this bird for a week or two, though I'm still seeing goldfinches at my feeder. Perhaps it's moved on (I hope). At any rate, here are the best photos yet, plus a video, to serve as a document. Previous post here.
Once again, for comparison's sake: the leucistic and a goldfinch with normal winter plumage.
