Cooper’s hawk (Accipiter cooperii) is a medium-sized hawk native to the North American continent and found from Southern Canada to Northern Mexico. As in many birds of prey, the male is smaller than the female. The birds found east of the Mississippi River tend to be larger on average than the birds found to the west.
Their breeding range extends from southern Canada to northern Mexico. They are generally distributed more to the south than the other North American accipiters, the sharp-shinned hawk and the northern goshawk. Birds from most of the Canadian and northern U.S. range migrate in winter, and some Cooper’s hawks winter as far south as Panama. The Cooper’s hawk occur in various types of mixed deciduous forests and open woodlands, including small woodlots, riparian woodlands in dry country, open and pinyon woodlands, and forested mountainous regions and also now nests in many cities. They were once thought to be adverse to cities and towns, but are now fairly common urban and suburban birds. The cities provide plenty of rock pigeon and mourning dove for the Cooper’s hawk to prey on. Although more adapatable in habitat than the sharp-shinned hawk, studies have indicated that the species still more often than not prefers sizeable tracts of woodland for breeding and migrating to fragmented, developed areas. source
