These baboons, remarkable for their bright red, hairless chests and throats, spend their days foraging in alpine meadows, eating grasses along with their seeds and bulbs. At night they sleep on small ledges lining cliff walls.
They live in large groups composed of up to four hundred individuals. Within these groups, social life focuses on smaller groups, which are typically made up of a single adult male and his harem of up to twelve females and their young.
Although the male helps keep the group together through vocalizations and facial gestures, the females influence the mating process, with the more dominant ones having the best access to the males.
This species is under threat due to habitat destruction and hunting.
