The Cooper's Hawk (Accipiter cooperii) in Bisbee, Arizona, located in the Mule Mountains, is a medium-sized hawk native to North America. This raptor is well-adapted to both woodland and urban environments, making it a common yet distinguished sight in the area.

Physical Description

Size and Build

Cooper's Hawks are relatively medium-sized birds of prey, with a length of about 14-20 inches and a wingspan ranging from 24 to 35 inches. They have a somewhat larger size compared to other Accipiters but are smaller than Red-tailed Hawks.

Plumage and Coloring

Adult Cooper's Hawks have a slate-gray back, reddish-barred chest, and underparts, with a dark cap on a paler nape and cheeks. Juveniles display brown upper parts and are streaked rather than barred with brown on the underparts. Their eyes are yellow at a young age but turn red in adulthood.
