Orangutans are among the most cognitively complex great apes, and their welfare in zoos requires sophisticated enrichment programs that engage their exceptional problem-solving abilities.
Orangutan welfare in captivity is fundamentally shaped by the degree to which their exceptional intelligence is engaged. Unstimulated orangutans in barren enclosures develop severe stereotypies and psychological abnormalities that reflect profound cognitive deprivation. Modern welfare programs provide foraging challenges that require multiple sequential problem-solving steps, novel materials on a rotating basis, and opportunities for tool construction and use. Some institutions have implemented tablet-based cognitive tasks that allow orangutans to engage with challenging problems on their own schedule. Social management requires careful attention to their semi-solitary wild social structure, avoiding forced social contact that causes stress.
