Observations on a small group of mountain gorillas (Gorilla gorilla beringei).
On the basis of a 5-month field study, data are presented on home range, patterns of daily movement and social behaviour in a small free-living gorilla group. Changes in group composition that occurred during the study are analysed with special reference to their effect on inter-individual distance. The relationships with other groups  and lone individuals whose home ranges overlapped with that of the group studied are examined on the basis of intergroup contacts.
