Gibbons are among the most vocal and acrobatically specialized primates, with welfare needs that are poorly met in captivity. Wild populations face habitat loss and the exotic pet trade.
Gibbons in captivity without adequate brachiating space develop severe stereotypic behaviors and show signs of chronic psychological distress. Their complex social bonds and vocal communication needs are impossible to meet in isolation or with inadequate space. The pet trade creates multiple layers of welfare harm: parental death, infant trauma from capture, and lifelong inadequate captive conditions. Wild gibbons in fragmented forests cannot complete their natural pair-bonding and territorial behavior, with population isolation leading to welfare-compromising inbreeding. Sanctuary rehabilitation programs that provide arboreal enrichment represent the most welfare-positive captive option.
