Black-crested Gibbons[1] (Nomascus concolor) are mainly found in southern China (Yunnan) and some distribution areas in northwestern Laos and northern Vietnam.
- Black-crested gibbons live in deciduous, evergreen, and semi-evergreen forests of mountainous and subtropical regions.
- The males are all black with hairless black faces, while the females are yellowish-beige with hairless black faces and black markings on the top of the head, abdomen, and chest.
- Females and males usually weigh between 7 and 10 kg. Like all gibbons, black-crested gibbons have a long arm length relative to body size.
