For those of you with a Facebook account, an unusual cedar waxwing was posted to the group Cornell Lab of Ornithology-Citizen Science-Birding the World. The waxwing has a protrusion from the back of its neck that looks a bit like a second head. It's as if it had a twin that was only partially absorbed. Does anyone have any idea what that might be?
