The rehabilitation of captive baboons.
Eleven baboons who had been singly housed indoors for an average of 5 years were moved to outdoor social groups in an attempt to provide a more species-typical environment and reduce high levels of abnormal behavior. Nine of the baboons were observed while in single housing and, over a 6-month period, while housed outdoors socially to document long-term changes in behavior. Abnormal behavior decreased significantly from an average of 14% of the observation time in the single cages to 3% in the sixth month of social housing. Cage manipulation and self-directed behaviors also significantly decreased, while social behavior, enrichment-directed behavior, and locomotion increased in social housing. Baboons that had been in long-term indoor single housing were able to reproduce and form stable social groups without injury. This study provides evidence that even behaviorally disturbed nonhuman primates can be successfully rehabilitated to live in social groups.
