Habitat: It inhabits grasslands and semidesert shrublands, and is rare in piņon-juniper woodlands. Breeding birds nest in isolated trees, on rock outcrops, structures such as windmills and power poles, or on the ground. Winter residents concentrate around prairie dog towns. Winter numbers and distribution fluctuate greatly according to the availabilty of prairie dogs; when a local prairie dog population dies off due to plague, hawk numbers decrease drastically. Migrants and winter residents may also occur in shrublands and agricultural areas.

Range in Colorado: Winter resident on eastern plains. At the same time it is a rare summer resident locally on eastern plains, and occurs very locally in Moffat and Routt counties (Felger 1910, Hendee 1929, Martin et al. 1974), along the Book Cliffs, in the Grand Valley, and in the San Luis Valley.

Status: State Special Concern
