This large hawk (18-23 inches) is the raptor most likely to be seen in southern Arizona. Found in a variety of habitats including farmlands, native grasslands and open desert, it is often seen atop utility poles or soaring in circles high overhead. In flight the distinctive rufous tail can be seen from below. When perched, it can be identified by a pale breast with a speckled band. Its wings are broad and its tail is rounded and broad. When it is searching for prey, this hawk will hover in place, seeming to hang motionless on the wind. It preys mainly on rodents, and is a common resident year-round in rural areas of southern Arizona. Numbers increase during migration and in winter.

According to desert expert Edmund C. Jaeger, large birds of prey such as hawks, eagles, and falcons are uncommonly successful in a desert habitat because they are able to get enough water for most of their needs from the body fluids of their prey--reptiles, birds, and small mammals. While these birds may drink water when it is available, they can easily get along without it.
