Social behavior of the pygmy chimpanzees

  • Suehisa Kuroda


The affinitive interactions among the pygmy chimps seem to be the most frequent in the male/female combination, next in the female/female, and the least frequent in the male/male. The differences of frequencies among the combinations, however, are little, and it may be said that the pygmy chimps are not so much biased by sex in the affinitive relations. Their aggressive behavior is mild, and their behavior in general shows high tolerance, especially between different sexes and among females. Similar tendency is also seen in grouping (Kuroda, 1979). Therefore, the pygmy chimp’s society may be said to be integrated by the male/female affinity, little differentiated by sex in the grouping and the affinitive relations, and with high inter-individual tolerance and coherence.
