Return of the “Gold”finches….almost — by Jan

American Goldfinch males are starting to look at bit like clowns!

Splotches of black feathers on the head…a bright yellow feather here and there among the tan.   Did they lose at paintball?

After last summer’s breeding, all Goldfinches gradually lost and replaced all their feathers. The new male feathers were not the bright “gold” of breeding season, but a more “understated” look similar to females– “basic plumage” in human words.

Now, in response to complex hormonal changes triggered by seasonal changes, one-by-one the body feathers (not tail or flight feathers) are being replaced. So going through these gradual changes, the males have some pretty strange looks before all of their breeding “gold” returns. (See photo with tiny “pin feathers” just beginning to grow.)

 

In the past 3 days we have banded 40+ Goldfinches…none in their full breeding plumage. It won’t be too long, though, until our Goldfinches are back in all their gilded glory.  This is just the beginning!
