Female impalas form clans that can consist of 6-100 individuals. Male impalas can live in the herd until they are about 4 years old, at which point they are driven out and may join a bachelor herd. Asserting their dominance is very important to males, especially during the breeding season. A male’s dominance status is signaled by a strong-smelling secretion from the skin on his forehead. They may also challenge each other by head-tossing or showing off their S-curved horns. Female impalas give birth to a single fawn per season after a 6-7 month gestation, although she can delay the birth by up to a month if conditions are not favorable.
