The impala is a medium-sized antelope native to eastern and southern Africa. Males usually weigh about 100–175 pounds, while females are smaller, often 88–117 pounds; shoulder height is about 28–36 inches. The coat is reddish-brown with white underparts, black tail and thigh markings, white eye and chin markings, and black hair tufts over scent glands near the hind legs. Only males carry the elegant lyre-shaped horns. Impala are highly athletic, fast, social antelope that both graze and browse. They entered U.S. zoos, safari parks, and private ranches during the mid-to-late 20th century, though they are less common than blackbuck, axis, or nilgai.
