African wild ass  (Equus africanus)

Biology

African wild asses have a fluid social arrangement and often form temporary aggregations of one or both sexes, which last no more than a few months and can contain as many as 50 individuals (4). Mature males however, tend to occupy large territories that are often situated around a water supply; these allow them to attain access to any receptive females passing through the area (5). Other males form bachelor groups and females may group with other females or with their own offspring. Mares tend to produce one foal every two years and births occur during the wet season (4).

Active in the cool of dawn and dusk, African wild asses seek shade in the heat of the day and are able to survive without water for a few days at a time (2). These grazers eat a variety of grasses and herbs, and in captivity have been known to live for 40 years (4).
