In our area, we have a significant number of hawks. While our pigeon cage was being cleaned last night, one of the pigeons that had never been outside was accidentally let out. Despite our efforts, we were unable to coax it back inside. When my son returned home from school, he discovered the poor bird with his head missing. I suspect a hawk may have caught it, although I would have expected the hawk to consume the entire pigeon. We live in CA. Thoughts on this?
