Sun bears are the smallest bear species and face unique welfare challenges in captivity, requiring specialized environments that reflect their arboreal forest lifestyle.
Sun bear welfare in captivity is often poor relative to what we know about their natural behavior. These intelligent, curious bears evolved in complex tropical forests where they range widely, climb extensively, and spend hours each day in elaborate foraging. Enclosures that lack climbing structures, vertical complexity, and foraging enrichment leave sun bears with little outlet for their natural behaviors. Behavioral research has shown that sun bears in barren environments develop high rates of stereotypic behaviors reflecting chronic frustration and poor welfare. Accredited facilities that provide forest-like environments with climbing structures, puzzle feeders, and varied substrates achieve dramatically better welfare outcomes and behavioral repertoires.
