Cooper's Hawk in The Backyard!


Caledonia Wisconsin

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. Other common names for the Cooper's hawk include: big blue darter, chicken hawk, flying cross, hen hawk, quail hawk, striker, and swift hawk.

The average mass of an adult male ranges from 220 to 440 g (7.8 to 15.5 oz) with a length between 35 and 46 cm (14 and 18 in). The adult male is significantly smaller than the average female, which weigh 330 to 700 g (12 to 25 oz) and measure 42 to 50 cm (17 to 20 in) long. Its wingspan ranges from 62 to 94 cm (24 to 37 in)
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.
