Sun bears are the world's smallest bear species with remarkable cognitive abilities. Their welfare in captivity requires adequate space, climbing structures, and foraging enrichment.
Sun bear welfare in captivity is particularly sensitive to enrichment quality. These cognitively complex animals spend extensive time in the wild foraging — extracting insects, honey, and plant material through exploration and manipulation. In barren enclosures, the motivation for these behaviours has nowhere to direct itself, resulting in high rates of stereotypic behaviour including rocking, pacing, and repetitive object manipulation. Providing foraging enrichment that engages the sun bear's remarkable tongue and manual dexterity, along with appropriate climbing structures, makes a measurable difference to welfare. The bear bile industry causes severe welfare harm to captive sun bears in Asia — bile extraction involves invasive procedures on bears kept in tiny crush cages for years.
