Hamadryas baboons have a fluffy coat. Females and young baboons are brown, while adult males have a silver hair on their shoulders and back. Their faces and rump have pink skin with no hair.
Grass seeds, root, and bulbs make up the diet of the Hamadryas baboon.
The Hamadryas baboon lives in Ethiopia, Saudi Arabia, Somalia and Yemen. It prefers the rocky desert areas and the subdesert regions that have grass.
Leopards are the main predator of this baboon.
The Hamadryas baboon has a complex social structure. A male will dominate up to 10 females at a time. This family is a close-knit group, interacting with each other far more frequently than with baboons from other families. Several families form a clan; several clans form a band; several bands form a troop. Males will forcefully steal females from other bands, but will not steal from their own family. Instead, they very gradually win over a juvenile female without confrontation. Young males inherit females from their father. Thus the father's social status is passed on to his sons. Females are much smaller than males, so they are not as forceful. However, if a female does not favor her male, she will have a much higher chance of being "stolen" from her male.
