Observation of wild chimpanzees and training for field research

Report:Tokuyama Nahoko

Date:2010/12/22 - 2011/01/10

In Karinzu forest, I observed chimpanzees for 7 days. I could observe two groups of chimpanzees. The group size of M group is about 60 individuals, and that of S group is about 20 individuals. For my field research training, I traced chimpanzees with tracker, and wrote down their activity in my field notebook. I recorded the number of chimpanzees and their name every hour, and estimated the party size and the party structure. I could observed various behavior of chimpanzees, such as feeding, mating, meet eating and begging, rain dance etc.
I observed L'Hoest's monkeys one day. I could observe two groups encountered and uttered alarm calls each other. So I supposed that the relationship of the neighbors was oppositional.
I went the small forest in Queen Elizabeth national park. The forest is surrounded by savanna, and the habitat of one group of chimpanzees. I couldn't observe them directly, but I was really impressed that chimpanzee's habitat had wide diversity.
I'm sure that this experience of observing wild chimpanzees helps my future study.
