The chimpanzee has an advanced cognitive map of its home range and can repeatedly find food. [58] The chimpanzee builds a sleeping nest in a tree in a different location each night, never using the same nest more than once. Chimpanzees sleep alone in separate nests except for infants or juvenile chimpanzees, which sleep with their mothers. [59]
Eventually they became so big that it was no longer possible for them to get both safe and proper sleep on bare branches alone, so they started building sleeping platforms in the trees. This appeared to have happened when their weight passed 30 kilos, as only apes above 32 kilos build nests. [16] [17] Which in turn led to shorter and deeper ...
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...

They can live over 30 years in both the wild and captivity. Chimpanzee (Pan troglodytes) (left) and bonobo (Pan paniscus) (right) Chimpanzees and bonobos are equally humanity's closest living relatives. They use a variety of sophisticated tools and construct elaborate sleeping nests each night from branches and foliage.
The bonobo (/ b ə ˈ n oʊ b oʊ, ˈ b ɒ n ə b oʊ /; Pan paniscus), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus Pan (the other being the common chimpanzee, Pan troglodytes).

Central chimpanzees live in social groups of around 66 individuals, on average this tends to be more than the group size of western chimpanzee counterparts. It was found that chimpanzees split activity budget into four main categories. [5] In chimpanzees there exists male dominance within these social groups.
