A female and a juvenile guinea baboon (Papio papio) at Port Lympne Wild Animal Park, England. This species is native to dry forests, gallery forests, and adjoining bush savannas in western Africa. This diurnal animal is primarily terrestrial, but sleeps in trees at night. More than 200 individuals may be in the same troop, which is limited in size by the number of suitable sleeping trees.Photograph: William Warby
