Enrichment strategies for mandrills in zoo environments, addressing their complex social and cognitive needs.
Mandrills are among the most socially complex primates in zoo collections. Their natural social structures — involving large, fluid multi-male groups with complex dominance hierarchies — are difficult to replicate in captivity. Incorrect group composition leads to chronic stress, injury, and reproductive failure. Welfare monitoring must include careful attention to behavioral diversity, social affiliative behaviors, and the expression of natural foraging sequences. Enrichment programs should prioritize foraging complexity, sensory novelty, and social management rather than passive entertainment objects.
