Description 

These monkeys are highly sexually dimorphic in size and pelage characters. Adult males weigh around 21.5 kg and females around 9.4 kg. Male pelage is basically grayish-brown in color, with the ventrum colored like the back or darker. Hairs on the cheeks are lighter. The long back hairs are wavey. Females are a plain olive-brown color. The skin may be very colorful in some animals. In both males and females, the skin surrounding the ischial callosities is pink or bright red. Males have skin of a similar color on their muzzle and face, whereas females possess a muted, grayish-brown face. The tail is long, and curved, with a graceful arch at the base. The natal pelage is black, although this is lost by approximately six months of age, when it is replaced by an olive-brown coat like that of the adult female.

Range and Habitat

Papio hamadryas is found on the African continent in the area of the southern Red Sea, in Ethiopia, Somalia, and Eritrea. Hamadryas baboons are found in subdesert, steppe, alpine grass meadows, plains, and shortgrass savannahs. Their distribution is limited by the availability of watering holes and appropriate sleeping rocks or cliffs. In parts of Ethiopia, they are found in agricultural areas and are considered crop pests.

Behavior

Baboons are terrestrial (ground dwelling) and are found in open savannah, open woodland and hills across Africa. Their diets are omnivorous, but mostly herbivorous, 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.

Diet

Papio hamadryas is omnivorous. They have been known to eat a variety of foods, including, but not limited to: fruits, tree gums, insects, eggs, acacia seeds, acacia flowers, grass seeds, grass, rhizomes, corms, roots tubers, small vertebrates. Because of the aridity of their habitat, these baboons must subsist on whatever edible items they can find.

Reproduction

Females characteristically have an estrous cycle of 31 to 35 days in length. Gestation lasts about 172 days, after which the female gives birth to a single offspring. The neonate, weighing from 600 to 900 g, has a black coat, making it readily identifiable from older infants. Infants are completely dependent upon their mother for the first few months, until they begin to eat solid food and are able to walk on their own. Puberty occurs between the ages of 4 and 6 years in males, and around the age of 4 years in females. 

Conservation Status

The species Listed in the IUCN Red List and evaluated as Least Concern.
