A group of baboons is called a troop. Baboons typically live in groups of 30 to 100 individuals, and the troops have complex social hierarchies. Males dominate rivals with shows of physical force. Grooming is an important social activity for baboons, and they spend hours on it daily.
Baboons can vocalize over 10 different sounds to communicate with other members of the troop. Four of the five baboon species live in savanna environments, and the other lives in hilly environments. They spend much of their time on the ground, but they climb trees to sleep, eat and avoid trouble. Baboons are omnivores, and some species can weigh as much as 82 pounds. Among other things, they eat fruit, grasses, birds and rodents.
