The average height of a chimpanzee standing upright is metres (4 ft) with the males weight ranging from 40 to 55 kgs (90 to pounds) and the females weight ranging from . On the other hand, body weights of adult male chimpanzees from the three populations do not show significant differences. Perhaps feeding competition among adult females in a small, isolated habitat is more severe than that among adult males, which may result in the body weight reduction among adult female chimpanzees at Gombe.
