Body Weight:
Male: 3.9-8.0 kg (8.6-18 lb)
Female: 3.4-5.3 kg (7.5-12 lb)

Head & Body Length:
Male: c. 490 mm (19 in)
Female: c. 446 mm (18 in)

Tail Length:
Male: 600-750 mm (24-30 in)
Female: 485-653 mm (19-26 in)

Pelage: Back and sides are mottled combinations
of light brown, grayish-brown, tawny, olive-brown,
olive-green, or brownish-yellow; belly and inner
limbs are white or off-white. Face black and ringed
in white fur. Feet and hands black, though more
pronounced in adult males.
Distribution & Status Behavior & Ecology
Range: Endemic to eastern and southern Africa.

Habitat: Found in savanna, open woodland, and
forest-grassland mosaic. Commonly associated
with water and Acacia trees. Extremely adaptable
and found in urban areas.

IUCN Status: Least Concern (2008 assessment); wide-spread and abundant with no major threats

CITES Status: Appendix II as of Jul 2018
Locomotion: Walk slowly to forage for food. Run
quickly and scale trees to escape predators. Leap
through trees, ricocheting off branches during inter-
group encounters

Activity Cycle: Diurnal monkeys, leave sleeping
trees near sunrise for daily foraging trips. Rest near
mid-day and visit watering locations. Spend most of
of the day eating.

Social Groups: Live in heterosexual groups;
composed of 2 or more females, their offspring, and
multiple males. Numbers range from 7-53, though
typically with fewer than 40 individuals. Linear
dominance hierarchies exist within each sex.

Diet: Omnivores who principally consume plant
products. Many populations rely heavily on the
leaves, thorns, flowers, pods and peas, gum, bark,
and wood of Acacia trees.

Predators: Medium to large mammalian carnivores
and eagles; particularly leopards, African Crowned
Eagle, and Martial Eagle. Predator specific alarm
calls warn group members of potential harm.
Reproduction & Development Species Highlights
Sexual Maturity: Females first reproduce at 4-6
years of age; males sexually mature at 5-6 years.

Gestation: 163-165 days, in managed care; estimate of
156-161 days in the wild.

Litter Size: 1-2, typically 1

Birth weight: 300-400g (0.7-0.9 lb)
Age at Weaning: Complete by c. 18 months

Longevity: To 17 yrs in the wild; up to c. 30 yrs in
managed care

Feature Facts

  • Diurnal, semi-terrestrial monkeys
  • Pronounced sexual dimorphism
  • Adult males are approximately 30% heavier than females
  • Dominant adult males display brightly colored red, white, and blue ano-genital regions
  • Highly social; produce numerous vocal calls
  • Over 30 distinct auditory sounds are used to warn members of danger and to maintain group cohesion 
  • As many as 53 monkeys may live together, though group size is typically less than 40 
  • Individuals gather in trees to sleep at night and travel together in daylight to forage and feed on various plant and animal foods
