In the United States, chickenhawk or chicken hawk is an unofficial designation for three species of North American hawks in the family Accipitridae: Cooper's hawk, the sharp-shinned hawk, and the Buteo species red-tailed hawk. The term "chicken hawk", however, is inaccurate. Although Cooper's and sharp-shinned hawks do primarily hunt other birds, chickens do not make up a significant part of their diets; red-tailed hawks may opportunistically hunt free-range poultry, but are chiefly predators of mammals such as rodents and rabbits.
