Eastern Chimpanzee, Pan troglodytes schweinfurthii

The eastern chimpanzee (Pan troglodytes schweinfurthii), a subspecies of the common chimpanzee, is a primate that can be found in Africa. Its range includes Burundi, Rwanda, Tanzania, Sudan, the Central African Republic, and the Democratic Republic of the Congo. It prefers to reside in trees, but it can also be seen on the ground.

Adult eastern chimpanzees can reach an average weight between 88 and 143 pounds, with males reaching an average height of 63 inches and females reaching a height of 51 inches. Its fur is course and black in color, while its face, fingers, and the soles of its palms and feet are pale. This species is about the size of a human, but is much stronger and it has extra gripping capabilities due to its opposable big toes and thumbs.

It is common for chimpanzees to reside in groups containing 20 to 150 individuals, although they travel in smaller groups of only a few individuals. They will spend the nighttime hours resting in the safety of trees and their active daytime hours moving about on the ground. This species walks on its hind feet and the knuckles of its front hands, like gorillas. Leopards and occasionally lions hunt the eastern chimpanzee and it will use a combination of loud screams and attacks with nearby objects to avoid becoming prey. It is an omnivore that will consume a large variety of foods including leaves, bark, fruits, seeds, insects, and small animals. It has been known to partake in organized hunts when hunting western red colobus monkeys and baby leopards, which is thought to be a protective measure.

The eastern chimpanzee has been the subject of extensive studies conducted by Dr. Jane Goodall in Gombe National Park, a protected area of its range. This species is threatened by habitat loss and hunting, as well as many of the diseases that afflict humans. It appears on the IUCN Red List with a conservation status of “Endangered.”
