The olive baboon lives in groups of 15–150, made up of a few
males, many females, and their young. Each baboon has a social
ranking somewhere in the group, depending on its dominance.
Newborns have black natal coats and bright pink skin. Females
are the primary caregivers of infants but males also play a
role. The species is the most widely ranging of all baboons; it
is found in 25 countries throughout Africa, extending from Mali
eastward to Ethiopia and Tanzania. Isolated populations are also
found in some mountainous regions of the Sahara.It inhabits
savannahs, steppes, and forests. Seen at Nairobi National Park
The first photo shows a male and female patrolling the grounds

food and last one of the baboons in its resting spot for the
