This afternoon I observed a very light-colored House Finch at the front feeder.  The patches of light brown, almost white, on his face were intriguing, so I got out the camera for a closer look.  With my zoom lens I could see that this was a juvenile bird, molting into his male adult plumage.

Goldilocks was more interested in the backs of her eyelids than in watching the bird-bird outside her window!
