Chimpanzees live in forests, underwoods and occasionally also clearer areas. They are active on trees as well as on the ground. Active day animals who sleep in nests built in tip of the trees. Diet consists of fruits, leaves, nuts and bugs. Sometimes they also eat meat when they hunt for small animals together. There are 20-30 chimpanzees living in one group and the hierarchy is complicated. Relationships between the members of the group are allowed and strangers are treated as hostiles. Reproduce throughout the year and after a 230-day pregnancy gives birth to one descendant. Offspring alienate at around 5 years of age from the mother. Chimpanzees reach their maturity at around 12 to 15 years old and can live up to 50 years. Genetically chimpanzees are the closest relatives to humans. Poaching and loss of habitat threatens the species.
Three chimpanzees currently live in Tallinn Zoo: male Pino and females Quincy and Betty.
