Primate Team

Javan gibbons


  • PRINCE (Primate Research Institute for Cognition and Ecology)

PRINCE (Primate Research INstitute for Cognition and Ecology) conducts cognitive research on orangutans at Seoul Zoo and ecological research on wild Javan gibbons at Gunung Halimun National Park in West Java, Indonesia.


  • Javan Gibbon Research & Conservation Project (JGRCP)

A long-term project to study and conserve Javan gibbons and provide stewardship for Gunung Halimun-Salak National Park. This is an internationally competitive research program to study Javan gibbons in the wild, a species that is relatively unstudied, and yet at the same, highly endangered. The long-term mission of the JGRCP in Gunung Halimun-Salak National Park in Indonesia is to study the behavioral ecology of the Javan gibbon, including development of a conservation plan to encourage sustainable economic development among villages along the park’s periphery. The project began in June 2007 and has been operating continuously since that time, making it the longest continuous primate research project on Java today. Currently there are three habituated social groups, with a total of 12 individuals. Research conducted thus far includes published work on foraging strategy (Kim et al. 2011, Kim et al. 2012), acoustic ecology (Ham et al. 2016, Ham et al. 2017), and other works in progress on topics including inter-group & intra-group interaction, social dynamics, feeding ecology, endocrinology of social monogamy, and nutritional requirements of lactation.


  • Research on ape cognition project in Seoul Zoo

The long-term goal of the PRINCE cognition project is to bring internationally competitive research on ape cognition to Korea. Currently the study includes a total of 6 chimpanzees and 4 orangutans. Research in progress includes experiments on prosocial behavior and tool-use. The objectives of this project are to contribute to a better understanding of social cognition in orangutans and chimpanzees, to provide behavioral enrichment to apes living in Seoul Zoo, and to improve public awareness about primate intelligence and welfare of captive animals. During the course of cognition research, the cognition team studied changes in fecal estrogen levels and sexual behavior (Kim, et al. 2012) conducted at Everland Zoo.
