Bald And Sick Baboon, Zimbabwe

A female initiates mating by presenting her swollen rump to the male's face.
Females typically give birth, usually to a single infant, after a six-month gestation. The young baboon weighs approximately 400 g and has a black epidermis when born. The females tend to be the primary caretaker of the young, although several females will share the duties for all of their offspring.
After about one year, the young animals are weaned. They reach sexual maturity in five to eight years. Baboon males leave their birth group, usually before they reach sexual maturity, whereas females are philopatric and stay in the same group their whole lives.
