The yellow baboon inhabits savannas and light forests in eastern Africa, from Kenya and Tanzania to Zimbabwe and Botswana. It is diurnal, terrestrial, and lives in complex, mixed-gender social groups of eight to 200 individuals per troop. It is omnivorous with a preference for fruits, but it also eats other plant parts, as well as insects. Baboons are highly opportunistic eaters and will eat almost any food they come across.
