Antelopes are a large group of hoofed animals that live mainly in Africa, with a few living in Asia. Antelopes belong to the same group of mammals as cattle, bison, sheep and goats. Gazelles also belong to this same group. Antelopes and their relatives have horns rather than antlers. These are made from bone and are permanent features on the heads.
The unusual name of this antelope is derived from the Zulu language, reflecting the native African name. They are generally seen in savanna areas.
Impalas will instinctively feed both by grazing at ground level, and also by browsing on taller plants, particularly when grass is hard to find during dry spells of weather. They tend not to stray far from water. Males will establish territories with herds of females, and mating takes place at the end of the wet season. The female later breaks away from the herd, giving birth alone. Mother and fawn will then rejoin the group; weaning occurs about six months later.
