I wouldn't have noticed the differences in juvenile plumage if we hadn't started feeding the birds last year.

New Dark-eyed Junco fledglings arrived last month and I started reading about differentiating plumage by Hatch-Year/Second-Year. I began to wonder if the ones that look "more adult" are the same fledglings that came by our (shoe) birdfeeders last year and if they share the same parents.

So much to learn!
