Orangutans are highly intelligent great apes with complex problem-solving abilities and extensive natural tool-use traditions. Meeting their cognitive welfare needs in zoos requires sophisticated, varied enrichment programmes.
Orangutan welfare in zoos centres on providing sufficient cognitive stimulation for animals whose wild counterparts spend years learning complex foraging and tool-use skills. Enrichment must go beyond novelty — it should offer genuine problem-solving challenges, variable reward schedules, and social learning opportunities. Technological solutions including touchscreen puzzle interfaces allow orangutans to engage in complex cognitive tasks. Foraging enrichment that requires multi-step problem-solving to access food occupies time meaningfully. Social groupings require careful management because orangutans are semi-solitary in the wild, and forced close proximity can cause conflict. Welfare assessments should track time spent in cognitive engagement versus stereotypic or inactive behaviour.
