Social enrichment for zoo primates - including opportunities for complex social interaction, cooperative tasks, and novel social situations - is among the most important welfare interventions available.
Social enrichment for zoo primates goes beyond providing companions - it requires attention to group composition, compatibility, space allocation, and management of social dynamics. Species-appropriate social groupings allow expression of natural behaviors from coalition formation in chimpanzees to multi-male groups in mandrills. The quality of social management is among the strongest predictors of primate welfare in captive settings, exceeding exhibit size as a welfare determinant.
