Sophisticated enrichment strategies that address the full behavioral and cognitive repertoire of sun bears in modern zoo environments.
Sun bears are among the most behaviorally complex and least understood bear species in captivity. Their high cognitive capacity and extensive wild foraging repertoire make them particularly vulnerable to boredom and frustration in poorly designed exhibits. Welfare assessment in sun bears should go beyond stereotypy absence to evaluate positive indicators including voluntary exploration, problem-solving engagement, play behavior and social flexibility. The most effective enrichment programs combine olfactory complexity, manipulable food sources requiring dexterity, vertical space for climbing and resting, and novel environmental features introduced on unpredictable schedules to maintain interest and cognitive engagement.
