Species (Cervus canadensis) of North American deer, often considered the same species as the red deer. Once common, the wapiti is now confined to the Rocky Mountains and southern Canada. It is the second-largest living deer species (the moose is first). Males may stand taller than 5 ft (1.5 m) at the shoulder and weigh up to 1,100 lbs (500 kg). The coat is brown, pale on the rump, and long and shaggy on the shoulders and neck. The male's five-tined antlers tower almost 4 ft (1.2 m) above his head. Wapiti live in large bands in winter and in small groups in summer. See alsoelk.
