There does not appear to be a specific breeding season for this species. Females become sexually receptive within three weeks of giving birth, and are capable of reproducing every 10-10.5 months. A pregnant female will separate from her herd prior to giving birth, and remain with her new calf for about five days afterwards. After the female has rejoined the herd, the young calf remains concealed for five more weeks, subsequently joining a ‘crèche’ with other youngsters in the herd.

Ecology and Behaviour

Roan antelope are usually most active in the morning, late afternoon, and evening. Roan antelope are relatively unwary, running away from a potential source of danger for a short distance, then stopping to look back. However, when pressured, they can run up to 57 kilometers per hour for considerable distances. If cornered, these antelope are formidable opponents, charging and brandishing their horns with skill. Roan antelope never move far from water (~4 kilometers at most), and overall have localised movements, using 200-400 hectares at any given time, with a home range no more than 10,000 hectares throughout the year. Neighbouring herds rarely share territory. Female herds are accompanied by a single adult male, who defends a wide swath (300-500 meters) around his herd against potential rivals. Young males are driven from their natal herds when they reach 2.5 years of age. Fighting for dominance is prevalent among both males and females, with the most dominant initiating herd movements. Fights occur with both animals on their “knees” (carpal joints) and are almost exclusively horn against horn.

Family group: Harem groups with a single dominant male with 6-15, rarely up to 35, animals. Males associate in bachelor herds of 2-5 animals.

Diet: Medium high grasses, rarely leaves.

Main Predators: Lion, leopard, spotted hyena, Cape hunting dog.

Habitat and Distribution

Lightly wooded country and grasslands throughout most of central Africa.
