Sun bears are the smallest bear species and among the most active foragers. Zoo welfare programs must provide extensive foraging enrichment, climbing structures, and respect for their primarily solitary nature.
Sun bears in zoos require environments that support their extraordinary foraging drive. Without adequate enrichment, they develop stereotypic behaviors including head-swaying and repetitive route-tracing. Providing termite mounds, honey-laced logs, and insect-stocked substrates engages their most motivated behaviors. Sun bears are physically capable of dismantling weakly constructed enrichment items rapidly — durable, refillable enrichment structures that require sustained effort provide the most sustained benefit. Their solitary nature means introductions must be managed cautiously, and cohabitation is rarely appropriate outside breeding pairs. Sun bear bile farming is an ongoing welfare emergency requiring advocacy and international pressure.
