Species: Theropithecus gelada - gelada
Subspecies: T. g. gelada - northern gelada
Pelage: Course, wiry hair; shade ranges from pale brown to near black. Males with long, thick mane that extends to the shoulders. Bright red, bare skin on the neck and chest shaped as an hour-glass. Buttocks hairless and calloused.
|Distribution & Status||Behavior & Ecology|
Range: Central Ethiopian plateau. Distribution bound by the Blue Nile River to the west and the Wabe Shebelle valley to the south. Three regionally isolated populations; the primary population inhabits the area south of Lake Tana and east of the Takkazzé River.
Habitat: High montane grasslands; never far from sharp escarpment edges, which provide shelter from predators and serve as locations for sleeping.
IUCN Status: Least Concern (2018 assessment)
CITES Status: Appendix II
Population in Wild: No recent population surveys. Very rough estimates of 200,000 individuals.
Locomotion: Terrestrial animals walk and run quadrupedally along the ground. Scoot with hindquarters along the ground while foraging.
Activity Cycle: Diurnal. In morning, ascend cliff-face to tops to feed. Travel slowly to feed along ridges before descending the cliff-sides to seek shelter and sleep at night.
Social Groups: Form stable social groups. One-male units (OMUs) or harems are composed of a single, adult male, several mature females, and their offspring. Sub-adult and adult males without females form all-male groups whose members cooperate to harass OMU leaders.
Diet: Vegetarians; primarily consume grass.
Predators: Few large carnivores within the species' distribution. Leopard (Panthera pardus), spotted hyena (Crocuta crocuta), humans and domestic dogs. Raptors may prey on the young.
