To collect behavioral data of chimpanzees in Kalinzu Forest, Uganda, for a study on behavioral diversity in wild chimpanzees.

Report: Sakamaki Tetsuya

Date:2009/01/25 - 2009/03/12

I departed from Japan on January 25th, 2009, stayed in the Kalinzu Forest Reserve from January 28th to March 9th, and returned to Japan on March 12th.
Study subject was M-group chimpanzees in the Kalinzu Forest Reserve. Most individuals of this group have been recognized and given names. I followed a group of individuals that I found, and observed them. I collected data of groupings, activities and behaviors by ad libitum sampling. In 32 research days, I found chimpanzees in 31 days. Total observation time was about 140 hours. Generally, males were more habituated than females, and some females were much more shy than others with human observers. Therefore, I mainly followed and observed males.
I also took part in an educational program of environments that were held on every Sunday with local peoples. I gave a seminar to show some relations of local people to animals in the forest where I had conducted field surveys in Tanzania and DR Congo.
