Great apes including chimpanzees, gorillas, and orangutans have profound cognitive and social needs that pose significant challenges for captive welfare management.
Great apes present the most complex welfare challenges of any zoo species because their cognitive and social sophistication means they have correspondingly complex needs that are difficult to meet in captivity. Chimpanzees in particular have social lives of extraordinary complexity, with alliances, politics, cultural traditions, and emotional bonds that span decades. Captive chimpanzee groups must be carefully managed to allow appropriate social dynamics while preventing serious aggression. The frequency of stereotypic behaviours in captive great apes across many institutions indicates that welfare needs are frequently unmet even in well-resourced settings. Some leading animal welfare thinkers argue that great ape cognitive complexity is precisely why they should not be kept in captivity at all, with sanctuary rather than zoo environments providing more appropriate lifelong care.
