Sun bears are the smallest bear species and among the most intelligent, with specialized behavioral needs that require creative zoo husbandry to meet.
Sun bear welfare in zoos requires enclosures with substantial climbing structures, as they spend significant time in trees naturally. Feeding enrichment should challenge their dexterous tongues and paws — puzzle feeders with honey, insects, and fruit replicate foraging behaviors. Sun bears kept without adequate enrichment develop stereotypic behaviors including repetitive pacing and swaying. Their solitary nature means pair or group housing requires careful compatibility assessment. Rescued bears from bile farms often arrive with severe physical and psychological trauma requiring long rehabilitation periods.
