We treated a pigeon back to health from a failed cat attack - healthy enough to eat and walk, but not fly. It took a while but she eventually fully regained her ability to fly. She had some rather distinct markings and would hang around the house pretty regularly after that. Then one day outside she was getting seriously groomed by a larger pigeon and wow is that where that term comes from? Anyhow yeah she returned the grooming (which I'd later look up was her way of saying 'yeah I'm down - let's go') and I never saw her, or him, again. So yeah - there could've been a happier ending there, especially because when a cat does eat a pigeon there tends to be evidence left.
