Gibbon rehabilitation centers across Southeast Asia work to restore social behavior and survival skills to individuals rescued from the pet trade — a challenging multi-year process with variable outcomes.
Gibbons rescued from the pet trade carry behavioral abnormalities from developmental deprivation. Social behavior — essential for pair bonding and territory defense — develops through years of observation and practice with conspecifics. Gibbons raised in human households without gibbon contact may never develop normal social repertoire, making them unable to form the permanent pair bonds that define gibbon social life. The rehabilitation process attempts to remediate this through careful introduction to conspecifics, large forested enclosures, and gradual reduction of human contact. Success is partial and variable — some individuals achieve sufficient normalization for wild release while others require lifetime sanctuary care. Each successful release represents the restoration of an individual to something close to its natural life, justifying the years of careful effort.
