PASSAGE II
Chimpanzees apparently live in troops of between twenty and
fifty animals. Within these troops, they form small groups of varying
compositions; the basic groups comprises Adult females spending much time
together often turn out to be mother and daughter, or sisters. Mother and
offspring live consistently, at least for the first four or five years.
Chimpanzees have a varied diet. In the forest, they are predominantly
fruit eaters, but in the open woodlands, the males sometimes kill and eat
colobus monkey or build on chimpanzee’s diet and is often eaten slowly and
deliberately with a mouthful of leaves between each bite. It is sometimes
shared out with other chimpanzees, who will be unusual among non-human
primates; with most other primates, it is everyone for himself. When the season
is right, chimpanzees in woodlands also eat termites and they go hunting for
termites, a chimpanzee will first carefully select a number of stems or pieces
of grass and trim them to the appropriate length. It will tend to ignore any
termite finds a mound ripe for fishing. A hole is scratched out with a finger
and the prepared stem is inserted. It is withdrawn, covered with termites and
passed carefully over removed.
