Managing silverback male gorillas in zoo settings presents complex welfare challenges around dominance, breeding, and the introduction of new individuals. Expert management is essential.
Zoo silverback welfare is inseparable from the welfare of his entire social group. A confident, established silverback with appropriate social control provides social stability that benefits all group members. Conversely, a silverback under challenge, inadequately housed, or socially frustrated creates anxiety throughout the group through behavioral displays and conflict. Management of silverback welfare requires space adequate for displays, hierarchical expression, and retreat from social tension. Exhibit design should allow the silverback to be visible to all group members (as in wild groups where his visibility provides security) while providing areas where he can be separated for feeding or veterinary management. Bachelor male management in separate enclosures requires complex enrichment and conspecific interaction to prevent behavioral deterioration.
