Eating crow
The term"Having to eat crow "is a falconry term originally I believe. If the falcon kills a crow or rook and is allowed to eat it they will often spit it back up, perhaps it's taste or texture. As a falconer my experience is mainly with hawks not falcons and they seem to have no problems. I do know from keeping crows for training hawks to hunt them that they are full of parasites even as babies and I had to de-worm them with Ivomec to prevent my birds from contracting them. Probably not what you wanted to hear but for what it's worth?
