Gorillas are the largest living primates, with sophisticated social structures that require expert management in zoo settings to meet both physical and psychological welfare needs.
Gorilla welfare in zoos is shaped by the complexity of their social structures and the long lifespan that creates decades of welfare obligation. Silverbacks that cannot exercise social leadership become frustrated and show aggression or withdrawal; subordinate males in groups without social structure opportunities suffer similar frustration. Female gorillas require stable social relationships for psychological health. Infant gorillas deprived of appropriate maternal care — a problem in earlier zoo eras — develop lasting behavioral abnormalities requiring intensive management. Modern gorilla facilities provide large, naturalistic indoor and outdoor spaces with varied foraging enrichment, complex social groups, and positive reinforcement training for veterinary care. Gorilla care has become one of the benchmarks of excellence in zoo animal management.
