Orangutans are highly intelligent great apes with extensive behavioral repertoires that require sophisticated zoo management, including cognitive enrichment and appropriate social grouping.
Orangutan welfare in captivity requires balancing their semi-solitary nature with needs for cognitive stimulation and appropriate social contact. The greatest welfare improvements come from environments that challenge their problem-solving abilities and allow expression of their remarkable manual dexterity. Barren environments produce abnormal behaviors that signal insufficient stimulation for one of the most cognitively sophisticated non-human animals. Complex environments with varied enrichment are non-negotiable for orangutan welfare.
