Chacma Baboon

Order Primates Family Cercopithecidae- Papio cyanocephalus ursinus
The chacma baboon is a highly gregarious diurnal primate. Home ranges of troops may overlap but they generally avoid contact with other troops. When out feeding dominant males tend to move near the front of the troop and dominant females (which are more likely to have young) move in the middle of the troop. Low ranking males tend to be at the back and less dominant females are usually on the outer edges. They are predominantly vegetarian taking browse and grazing and will occasionally take birds and small mammals up to the size of infant impala.
The troops are female-bonded groups with males dispersing from troop to troop but females remaining in their troop of birth. They are territorial and males and females have separate hierarchies with only dominant males having access to oestrus females. Higher ranking females are mated by the most dominant males. Gestation is 6 months and a single young is born. Breeding is throughout the year. Serious fighting is rare but there is constant squabbling and posturing to reaffirm social hierarchy amongst individuals of the same sex. Average lifespan is 18 years.
When a predator is detected the baboons will bark and stare at the animal, often bobbing up and down. In trees they will often shake the branches as a threat display. The main defence of baboons is their willingness to defend other members of the group under attack. Males have canines that can be in excess of 6cm and there are many records of males attacking and killing leopard.
i The sexual skin around the ischial callosities changes colour depending on whether a female is pregnant, lactating or receptive. The skin becomes swollen at the onset of menstruation and deflates after ovulation. Young are born after a gestation of 6 months.
The female ischial callosities are divided whereas the males are fused.
