The Cooper's Hawk is a largely North American species that occurs as a breeder in the mountains of Mexico and in winter south to northern Central America. A medium-sized Accipiter, it has a long tail and rounded wings. Adults are gray above and banded rufous above, thus resembling the sympatric Sharp-shinned Hawk (A. striatus), from which they are distinguished by their larger size, dark cap, and more-rounded tail. Immatures are brown above and streaked white below, and are distinguished from immature Sharp-shinned by size, shape, and the narrower streaks on their underparts. The Cooper's feeds largely on birds taken in an ambush or in active aerial pursuit, but also takes mammals. It builds a stick platform in a tall tree, often near a clearing.
