Orangutans are highly intelligent and largely solitary in the wild, requiring complex cognitive enrichment programmes in captivity to prevent boredom and stereotypic behaviour.
Orangutans in captivity face the challenge of having extraordinary cognitive abilities but limited natural stimulation. Without sustained cognitive enrichment, they show boredom behaviours and stereotypies. The best modern zoo programmes provide varied foraging challenges, training participation in veterinary care, and social opportunities appropriate to their semi-solitary nature.
