Abstract

Animals often exhibit behavioural flexibility in different habitats, and ecological and social factors can shape variation in both foraging and grouping patterns. I conducted 16-months of field research on chimpanzees in a montane forest in Rwanda and showed that their diet diverges from those at lower-elevations through lower dietary breadth and fruit consumption. These differences likely stem from lower botanical diversity and productivity at higher elevations. Limited food supply was predicted to constrain chimpanzee grouping patterns; however, I found that sexually receptive females were the main driver of grouping patterns, overshadowing ecological influences.
