Sun bears in zoos present distinctive welfare challenges due to their highly active, wide-ranging natural behaviours and their sensitivity to both barren environments and inappropriate social groupings.
Sun bear welfare in zoological collections requires particularly sophisticated enrichment and management, as these bears have highly motivated foraging behaviours that must be met daily. Sun bears denied complex foraging opportunities develop stereotypies rapidly and show signs of chronic stress. Their natural solitary tendencies also create management challenges - forced proximity with incompatible conspecifics causes significant stress and aggression. Leading zoos provide multilayer, highly complex enclosures with multiple foraging zones, vegetation cover, climbing structures, and daily delivery of challenging food puzzles that occupy these intelligent animals appropriately.
