One member of the household, who shall remain nameless, despite having a harness and muzzle managed to somehow get a few feathers from a pigeon wandering round the market square whilst we were having coffee. The pigeon promptly managed to fly off to the top of the bank where of course is stayed. Don't know how it did after that obviously, no obvious blood - a few small feathers and one or two big ones.
The reason we aren't knee deep in pigeons is that they are very stupid, it was wandering round despite a very large predator showing a keen interest in it. It can be excused for not understanding the significance of the muzzle, but not the large predator.
