A couple of American Goldfinches and a single House Finch. The American Goldfinch changes from winter plumage to breeding plumage by a complete molt of its body feathers. It is the only member of its family to have this second molt in the spring; all the other species have just one molt each year in the fall. The American Goldfinch is mostly monogamous, but a number of females switch mates after producing a first brood. The first male takes care of the fledglings while the female goes off to start another brood with a different male.
