Abstract

Abnormal behaviors occurring in some captive orangutans include lack of maternal skills, stereotypic behaviors, atypical sexual behavior and hyper-aggressiveness. Changes in social groupings, improved housing, behavioral enrichment and positive reinforcement training are known to alleviate some of these undesirable behaviors.
