Abstract
From 16-10-03 to 16-12-03 I studied four male gray-shanked Douc (GSD) langurs (Pygathrix cinerea) in a semi-captive environment and compared results to wild GSD langurs that were studied from 2006-2008. The semi-captive GSD langurs live at the Endangered Primate Rescue Center (EPRC) in Cúc Phương National Park, Vietnam. Four GSD langur males, three born in captivity and one rescued from the pet trade, share 5 hectares of limestone forest in a semi-captive setting at the EPRC. The semi-captive environment is intended to prepare members of this species and other endangered primates for potential release into the wild. In my study, I assessed the group members' activity budgets and feeding behaviors and compared my data to that obtained in a study of wild GSD langurs. I collected data using instantaneous scan sampling at 2 minute intervals (Altmann, 1974). This comparison may assist future conservationists in their efforts to restore wild GSD langur populations in appropriate habitats that may encourage wild behaviors by reintroduced subjects.
