Study on Social behaviors of Wild Borneo Orangutans ; focusing on males
Date:2008/08/07 - 2008/08/25
We have continued the field research on wild orangutan in a research area which we newly settled around a tourist lodge in Danum Valley Conservation Area, Malaysia.
About 5 year has passed since we set up this new research area.
During the research on August 2008, I could track and observe 10 orangutans (2 of flanged male were new individuals, others were resident individuals).
In addition, I conducted fallen fruits census and nest census.
