Birds of prey are simply birds that eat other animals. Thus, a robin or a Steller's Jay would be a bird of prey. Raptors have a few adaptations to set them apart from the other birds of prey. They have excellent vision, sharp , hooked beaks, superior hearing, and their feet have long claws called talons.
Raptors have the most developed hearing in the avian world.
Based on the sounds they make, their hearing is both broad and acute. From the deep call of the great gray owl to the high pitched chatter of the American Kestrel, sound is their primary form of communication.
