Primates in zoos face welfare challenges from insufficient social group complexity, limited cognitive stimulation, inadequate space, and the psychological effects of captivity on cognitively sophisticated animals.
Primate welfare in zoos is one of the most ethically complex areas of captive animal management. Great apes are cognitively sophisticated animals with emotional lives, cultural traditions, and complex social needs that cannot be adequately met in standard zoo exhibits. Artificial social groupings disrupt the long-term relationship structures primates depend on for psychological stability. Restricted ranging causes chronic frustration. Behaviours including self-harming, rocking, and regurgitation indicate poor welfare and are documented in zoo primate populations. Best-practice primate welfare requires large, complex exhibits, stable social groups of appropriate size and composition, and cognitively stimulating enrichment - standards that few facilities fully achieve.
