I feed the birds every morning. Today I saw a pigeon who was not flocking with the others. While he was walking on the ground I noticed he had the feathers and skin on the back of his head neck ripped off. The back of his skull is exposed. What an upsetting sight! I threw extra birdseed out right next to him and he is eating it. I can tell he's in a lot of pain. Probably got attacked by a hawk and lived to tell about it. Nature can be a cruel thing.
