They live in separate flocks, with the females and their offspring and bachelors in one flock while the adult males live in a separate flock.

The adult males only join the females in the mating season. It is then, in the rut, from December-January, when there are tremendous fights between adult males to attain dominancy in the group and mate with the females. The females have only one kid, which is born after a six-month gestation period.
