Hylobates lar

Back To Species Guides

APHIS includes this species in its gibbon factsheet. The fact sheet provides group-level care information; individual needs and behavior vary, and professional primate-care guidance is essential.

Diet

The APHIS gibbon factsheet describes a varied diet including fruits and vegetables, leaf-eater primate biscuits, and browse. It notes that large amounts of some high-acid fruits may cause digestive illness. Work with a veterinarian experienced with primates on an individual diet.

Behavior and Habits

APHIS describes gibbons as highly intelligent, territorial, and adapted for brachiation. The factsheet notes family-group social patterns and vocal behavior; needs can differ among species and individuals.

Habitat and Enclosure

The APHIS factsheet discusses vertical pathways for brachiation, climbing structures, shade, visual barriers, and a nest box or night den. These are general reference points, not a facility design or compliance plan.

Social Needs

APHIS describes family-group social patterns and territorial behavior. Introductions, separation, and group composition should be planned and monitored by qualified primate-care professionals.

Safe Interaction and Compatibility

APHIS describes overlapping wild territories among some gibbons and cites one successful same-sex adult female lar/grey gibbon pairing. This single report is not a guarantee; get individual expert assessment.

Enrichment

APHIS highlights varied, novel enrichment, including foraging, puzzle feeders, and browse. Individual enrichment plans should be designed by experienced animal-care staff.

Health and Veterinary Care

APHIS identifies infectious diarrhea, hepatitis B, and abnormal behavior among welfare concerns discussed in its gibbon factsheet. Consult a veterinarian experienced with primates for preventive and clinical care.
