Sun bears are highly intelligent, arboreal bears from Southeast Asia whose welfare in zoos requires complex climbing structures, foraging enrichment, and careful social management.
Sun bear welfare in zoos requires attention to their arboreal lifestyle and specialized foraging behaviors. Enclosures must provide substantial climbing structures at multiple heights — sun bears denied vertical space cannot express their natural locomotion. Foraging enrichment using honey, insects, and varied fruits distributed in complex ways mimics their wild feeding behavior and provides essential cognitive stimulation. Sun bears at bear bile farms in Vietnam and China experience some of the most severe sustained suffering in any animal husbandry system — chronic pain, infection, and psychological trauma from invasive procedures. Rescued bears often carry permanent behavioral and physical damage. Zoo-based sun bear welfare programs, when excellent, serve as important advocacy tools against the bile industry.
