This was solitary bird at feed Dec 13 near Saltville VA. Head is black and crow like. Black eyes and bill. Bird slightly larger than Blue Jay. Thanks, Vicky
From the back it's hard to make a positive identification, but I can see a small amount of white on the wing. From your description, this looks like it could be a Red-Winged Black Bird, possibly an immature male. They normally fly in flocks but I've seen single birds at my feeders before.
