Gibbons are the most species-rich family of apes, known for their complex songs and highly acrobatic locomotion. Their welfare in captivity depends on brachiation opportunities and social management.
Gibbon welfare in captivity is shaped by two fundamental requirements: a partner and space for brachiation. Gibbons are pair-bonded animals that form long-term monogamous bonds reinforced through daily duetting; without a compatible companion, they experience social deprivation that manifests in self-directed repetitive behaviour and self-injury. Brachiation — swinging through structures using arm-over-arm locomotion — is the primary mode of movement for which gibbons are anatomically specialised; without structures that allow this, musculoskeletal conditions develop that cause chronic pain and impaired movement. The exotic pet trade creates a rehabilitation crisis: gibbons removed from their mothers as infants and raised in human households develop abnormal social attachments that make reintegration with conspecifics extremely difficult, requiring years of patient rehabilitation.
