Sun bear welfare in zoos requires management of their unique foraging ecology, marking behavior and solitary social preferences in naturalistic enclosures that support normal behavioral expression.
Sun bear welfare management requires understanding of this species' specialized foraging ecology and its implications for enrichment design. The extraordinary tongue adaptation for extracting food from cavities means that feeding enrichment must incorporate challenge-based food extraction to meet this behavioral motivation. Scent marking using facial and chest glands is a normal behavior requiring substrate and structures that enable marking expression. Cognitive enrichment must be commensurate with sun bear intelligence to prevent the boredom that drives stereotypic behaviors. Social management requires recognizing their largely solitary nature while providing appropriate social exposure. The global conservation crisis facing sun bears from habitat loss and the bile farming industry makes welfare quality in zoo populations particularly important for conservation education.
