2 Owl Information Owls along with hawks, eagles and falcons, make up a group called "raptors" or birds of prey, whose members have talons (sharp claws) on their feet for catching prey and hooked beaks for tearing it apart. To aid in nighttime hunting, owls use a surprise attack. Having located their game, they fly in quickly, feet first. Killing is rapid and the victim is usually carried in the feet or beak to a perch or nest where it is devoured.

3 How do Owls eat? Large items are torn apart with talons and beak. Small morsels, such as mice, are swallowed whole. Hours later indigestible bones, fur and feather are coughed up in firm, cylindrical one-to-two-inch pellets. Sometimes many of these pellets can be found under a favorite perch or nest. By identifying the remains in the pellets, the owl's food habits can be studied.
