Impalas are medium-sized antelopes that roam the savanna and light woodlands of eastern and southern Africa. In the rainy season, when food is plentiful, they may gather in large herds of several hundred animals to browse on grasses and herbs, bushes, shrubs, and shoots.
Herds offer protection from predators, such as lions. An alert impala will bark out an alarm that puts the entire herd to flight—and a fleeing impala is no easy prey.
Impalas are fleet runners who are able to leap distances of up to 33 feet. They use this technique to escape predators and sometimes, apparently, simply to amuse themselves. The impala can also clear bushes and other obstacles by soaring some 10 feet in the air. Typically, a running impala will simply jump over anything in its path.
Mating and Reproduction
This graceful antelope is known for its long, spiral horns, which males use to challenge each other in tests of strength. Older impala males stake out mating territories and herd groups of females that they jealously guard against any rivals. During this exhausting mating period, the male must fight off challengers, herd his females, and mate with them. Unsuccessful bids to take over a male's territory usually end with the loser retreating to join a bachelor herd.
Females typically give birth about seven months after they mate, usually to a single impala. Both mother and baby join a herd of females and offspring within a few days.
