In their habitat in the forests of central Africa, chimpanzees spend most of their days in the tree tops. When they do come down to earth, chimps usually travel on all fours, though they can walk on their legs like humans for as far as a mile. They use sticks to fish termites out of mounds and bunches of leaves to sop up drinking water.
Gorilla and chimpanzee populations in Central Africa continue to decline due to poaching, habitat loss and disease. National parks and reserves in six range countries protect only 21 percent of western lowland gorillas
