In Australia, a large hawk of the genus Hamirostra is called a black-breasted buzzard. The buteos, also called buzzard hawks, can usually be distinguished when soaring by their broad wings and expansive rounded tail. The plumage of most species is dark brown above and white or mottled brown below; the tail and underside of the wings are usually barred. Buteos customarily prey on insects, small mammals, and occasionally birds. They nest in trees or on cliffs. Species range over much of the New World, Eurasia, and Africa. The red-tailed hawk, the most common North American buteo, is about 2 ft (60 cm) long.
