Research Abstract

Half a century of dedicated field research on wild chimpanzees has revealed that there are variations of behaviors among study groups and there are inherited between generations. The author has been conducting a field research on wild bonobos at Wamba, D. R. Congo and chimpanzees at the Kalinzu Forest, Uganda. The author described the ethogram (a list of behavioral repertoires) for each study group and compared the behavioral repertoires between chimpanzees and bonobos. In the chimpanzee group, the author found that there are tool-using behaviors, such as ant-dipping behavior and collecting honey with sticks. Moreover, the author compared the sexual behavior of both species. The author revealed that female chimpanzees were active in copulation while female bonobos played only a passive role in the copulatory behavior sequences. These results were published in Primates. The author cooperated with researchers from other study sites of chimpanzees and bonobos and took part in creating the ethogram which covers all the study site of both species.
