A white patch of hair appears on their rumps at about the same time they begin to walk (animal corner).

The rump patch begins to disappear at about age 3, the same age that weaning usually begins (animal corner). Females remain with their natal group until about age 8 or 9, then join an unrelated group or a solitary male (animal corner). Males remain with their natal group until about age 12, then begin to go off on their own (animal corner). Solitary males try to attract females from other groups to form their own group (animal corner). The frequency and duration of sexual activity in gorillas are low in comparison to other great apes (animal corner). Only the silverback, or dominant male, can mate with the adult females in his group (animal corner). The reproductive success of males depends upon the maintenance of exclusive rights to adult females, which is ensured by males forming a permanent bond with each female in a social group (animal corner). The formation of these bonds keeps adult females from leaving the group or mating with other males.
