Abstract

Unlike other chimpanzee food items, the leaves of Aspilia pluriseta, A. rudis and A. mossambicensis (Compositae) are eaten without being chewed. Moreover, A. pluriseta and A. rudis are eaten slowly and singly and particularly in the early morning. This unusual behavior suggests that Aspilia leaves offer peculiar stimuli, perhaps with pharmacological effects.
