CENTRAL AFRICAN CHIMPANZEES
In local languages : Mokomboso (Lingala), Sumbu (Bendzele), Seku (Mbangombe)
Omnivorous, chimpanzees (Pan troglodytes troglodytes) feed extremely differently depending on their environment, their group and the season. Half of their diet is usually composed of fruits, but they also enjoy leaves, bark, stems, as well as insects, eggs and nestlings. Up to 300 different food types have been recorded, and as many as 20 in a single day.
After humans, chimpanzees show the most diverse and complex tool-using repertoires of all species. They can delicately fish for termites, inserting small rods into termite mounds, as well as use large branches like clubs to break through the bark of a tree and collect the honey that hides there.
Social and curious, chimpanzees offer to observe captivating behaviors: using stones to crack nuts or cooperating to opportunisticly hunt duikers. Different chimpanzee populations have different behavioral repertoires, and specific behaviors can be culturally transmitted from parents to offspring.
A 2022 study, drawn from more than 20 years of observations at Nouabalé-Ndoki National Park, reveals first evidence of lasting social relationships between chimpanzees and gorillas. Observations include playful as well as aggressive behaviors between the two species, and individuals traveling through a group of the other species to seek out another particular individual. These interactions may afford unique development opportunities that extend the individual’s social, physical and cognitive competencies.
