At the beginning of this week I have visited the Museum für Naturkunde in Berlin to collect additional orangutan data for our research project on great apes ecology. In particular, I was looking to the Sumatran orangutans, ecologically and morphologically different from Bornean orangutans, and thus considerate a separate species, Pongo abelii. I need to thank Steffen Bock, the collection manager, who helped me during my stay at the museum. A wonderful natural history museum that I suggest you all visit it. See some pics below:
