Abstract
The diachronic changes of two gorilla groups in the Kahuzi region are studied. The death of a leader male resulted in the size changes of the two groups. Both groups' ranging areas and patterns are compared with former reports. Inter-group relationships, intra-group interactions and files of procession are described. The social organization and female transfer system of gorillas are discussed, and an explanation for infanticide is presented.
