Gorillas in zoos require sophisticated behavioral enrichment programs that address their cognitive complexity, social needs, and foraging motivation to maintain psychological welfare in captive settings.
Gorilla welfare in captivity is shaped by the tension between their need for stable social structures and the zoo management requirements of genetic mixing, transfers, and introductions that regularly disrupt those structures. Individual gorillas who lose familiar social partners show measurable grief responses. Cognitive enrichment that keeps gorillas mentally engaged throughout the day is essential for positive welfare; under-stimulated gorillas develop stereotypic behaviors and social pathologies. Zoos committed to gorilla welfare invest heavily in complex feeding enrichment that extends foraging time and program enrichment to individual preferences.
