Nyala are not territorial. Although they frequent thick vegetation, they will venture into open areas to graze fine grasses and forbes. They prefer succulent, higher-protein vegetation. Horns and hooves are used to dig tubers. Because of their more specialized diet, nyala groups are not large and they move very erratically as they forage. Their specialized diet may be the reason they are not numerous or widely spread. They do not have the explosive running ability of the open-ground antelope and so must depend on melting into the vegetation to escape predators. The white under-tail serves as a warning flag to other herd members as they bark and bound for cover on sighting a predator.

Diet - Herbivores

They are predominantly browsers, but do graze occasionally. They carefully select higher quality food items, including fruits, seed pods, flowers, and tender leaves, occasionally taking tender bark and tubers.


Females are mature at about two years. They tend to stay with the mother's group and so the small herds are usually related females. Males disperse into bachelor groups, becoming more solitary toward maturity.

Female groups will be followed by a variety of males until the breeding season arrives. Then, only the dominant bull of the area will stay with the group.


One calf is born after a gestation of about 7 months.
