I photographed this bird today at Lake Fairfax in northern Virginia, US. It was hanging out in some trees by the lake with some dark-eyed juncos and some cedar waxwings. Despite the spotted chin, I don't think it's a house sparrow. The spots on the breast remind me of a hermit thrush, but the color seems too gray to me. My apologies for the bad angle; these are the only two shots I have. Does anyone have any guesses?
