The Bale Mountains vervet is diurnal and spends most of its time feeding. The seasonal availability of food means that this species varies its diet during the year, mainly feeding on fruit in the dry season, and bamboo shoots and roots in the wet season. The Bale Mountains vervet also feeds on young bamboo leaves, flowers and insects (3).
The Bale Mountains vervet usually lives in large, mixed groups of between 15 and 30 members (3). Typically, vervet groups have more females than males, and a clear dominance hierarchy determines the rank of each member of the group (3) (4). Groups are mainly made up of related females, that remain in their natal area, and unrelated sexually mature males (4).
Very little is known about the reproductive biology of the Bale Mountains vervet; however, females in the Chlorocebus genus are usually sexually mature at four years of age. The gestation period is usually between 163 and 165 days, and females give birth during the wet season to a single offspring (3) (4).
