Raptors, or birds of prey, hunt mammals, reptiles, fish and other birds. They grab their prey in flight, either in the air, from the ground or out of the water. That is why they have sharp claws, called talons. In order to rip their victim apart, they also have a strong hooked bill. Raptors have very keen eyesight and therefore usually hunt during the day. Peregrines are an exception, hunting often at dusk.
