Chacma baboons mating at Cape Point in South Africa. 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.
The chacma baboon (Papio ursinus), also known as the Cape baboon, is, like all other baboons, from the Old World monkey family. It is one of the largest of all monkeys. Located primarily in southern Africa, the chacma baboon has a wide variety of social behaviours, including a dominance hierarchy, collective foraging, adoption of young by females, and friendship pai
Like other baboons, the hamadryas baboon breeds aseasonally. The dominant male of a one-male unit does most of the mating, though other males may occasionally sneak in copulations, as well. [12] [14] [17] [26] Females do most of the parenting. They nurse and groom the infant and one female in a unit may groom an infant that is not hers.

Baboon researcher Esme Beamish, from Cape Town University’s Institute for Communities and Wildlife in Africa, explains that it makes sense for the monkeys to venture into the city in search of food.
In baboons, the more mature and dominant males mate most repetitively with the most receptive females at peak swelling. Young males get access to mate, though much less frequently, and only within the confines of female baboon mating strategy, which advantages non-conceptive mounting as a defense against them.
This behavior also occurs in hamadryas baboons (Papio hamadryas), where the leader males practice intensive mate guarding. [26] In Drosophila montana, studies have shown that following mate guarding, the chances of a female mating with or being inseminated by another male were greatly diminished. This shows that the mate guarding tactic can be ...
Sonograms of female copulatory vocalizations of a human female (top), female baboon (middle), and female gibbon (bottom), [19] with time being plotted on the x-axis and the pitch being represented on the y-axis. In non-human primates, copulatory vocalizations begin towards the end of the copulatory act or even after copulation. [2]
