Hawks, falcons and owls kill and eat live prey, generally. When we were training them for falconry, they would come to a gloved hand holding a small piece of meat, so I suppose they may eat something dead in a pinch.

Anyway, the point I wanted to say is that they eat everything except the fur or feathers that they can pull off prior to eating. Then, after digestion, they regurgitate a ball or pellet containing the bones, fethers and fur. It's usually so complete that you can reconstruct the skelaton to ID the critter.

And thank your lucky stars that the owl DIDN"T step up on your fingers. When they perch on a falconers glove, the talon tips OFTEN pierce through enough to feel the tips. The gloves are nearly as thick as a welders glove. I guess one redeeming factor is owl talons don't have barbs!
