I was driving on a back road this morning. I passed a dead deer on the side of the road. There were 4 black vultures on the deer. At least there were three vultures and another bird that seemed to be congregating with them. The fourth bird looked like a black vulture, but it had a white head and large white patches on its wings. Black vultures seem to have replaced turkey vultures in this area in the past 10 or 12 years, but I never saw one marked like this one.
