Augur Buzzard
The Augur buzzard (Buteo augur) is also called the African red-tailed hawk. As with the red-tailed hawk, the Augur buzzard's extreme prevalence in Africa means humans see these birds of prey frequently. Slightly smaller than the red-tailed hawk, Augur buzzards weigh up to 3 lbs. with a wingspan no greater than 3 feet. Augur buzzards are white and grey, with red tail feathers. Augur buzzards primarily feed on reptiles.
Red-shouldered Hawk
The least common hawk in North America, the red-shouldered hawk (Buteo lineatus), lives in the forest by water. Red-shouldered hawks have a wingspan of up to approximately 3 1/2 feet and weigh just over 1 lb. maximum. Primarily brown and red, red-shouldered hawks have a distinct black striped tail. Red-shouldered hawks eat snakes, fish and frogs among other creatures.
Rough-legged Hawk
Rough-legged hawks (Buteo lagopus) are named for their feather-covered legs. The body and wings of rough-legged hawks are brown and white. The rough-legged hawk has a wingspan of approximately 4 1/2 feet and weighs up to 3 lbs. During the summer, rough-legged hawks live and breed in the Arctic. These birds of prey use Caribou bones to build nests. The rough-legged hawk lives in the United States during winter. Rough-legged hawks eat rodents and carrion.
Swainson's Hawk
The Swainson's hawk (Buteo swainsoni) lives on North American plains and grasslands. During migration this bird of prey is also seen in Central and South America, particularly Argentina. Swainson's hawks have a wingspan up to 4 1/2 feet and weigh approximately 1 to 3 lbs. Swainson's hawks are dark brown with patches of white and red. The Swainson's hawk eats mammals and insects.
