"Owl Keyring. Owls are birds of prey. Owls mostly hunt small mammals, insects, and other birds. They are found all over Earth. Most owls are nocturnal, hunting for prey only in darkness. Owls are far-sighted, and can't see anything within a few inches of their eyes. Their far vision is exceptionally good and they can turn their head 135 degrees in both directions to look behind their own shoulders!
