Chacma Baboons (Papio ursinus) are the largest non-human primates in southern Africa. They are highly gregarious, social animals that live in troops of about 15 to 100. All males of breeding age are dominant over females, but males have a strict rank order within the troop. Baboons are omnivorous, eating a wide range of plant and animal foods. This troop was on the edge of the Nyamarhi Spring in northern Kruger Park, feeding, grooming and with the youngsters playing. Baboons are often seen with antelopes like these Blue Wildebeest. They gain mutual benefit – antelopes have better the hearing and sense of smell and Baboons have excellent eyesight, and often gang up to chase predators away.
