Baboons in the Warsaw zoo.
Baboons are terrestrial (ground dwelling) and are found in open savannah, open woodland and hills across Africa. Their diet is omnivorous, but mostly vegetarian; yet they eat insects and occasionally prey on fish, shellfish, hares, birds, vervet monkeys, and small antelopes. They are foragers and are active at irregular times throughout the day and night. They can raid human dwellings and in South Africa they have been known to prey on sheep and goats.
Baboons in captivity have been known to live up to 45 years, while in the wild their life expectancy is about 30 years.
Most baboons live in hierarchical troops. Group sizes vary between 5 to 250 animals (often about 50 or so), depending on specific circumstances, especially species and time of year.
Baboon mating behavior varies greatly depending on the social structure of the troop. In the mixed groups of savanna baboons, each male can mate with any female. The mating order among the males depends partially on their social ranking, and fights between males are not unusual. There are however more subtle possibilities; in mixed groups males sometimes try to win the friendship of females. To garner this friendship, they may help groom the female, help care for her young, or supply them with food. The probability is high that those young are their offspring. Some females clearly prefer such friendly males as mates. A female initiates mating by presenting her swollen rump to the male. But "presenting" can also be used as a submissive gesture and is observed in males as well. Females typically give birth every other year, usually to a single infant, after a six month gestation.
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 life.
