Appearance

The species exhibits sexual dichromatism, the male is completely black, while the female is a golden or buff colour with variable black patches, among them a black streak on the head.

The length from the head to the end of body is 43–54 cm (17–21 in) and it weighs from 6.9 to 10 kg (15 to 22 lb).

Range and habitat

One thousand years ago, gibbons that may have been crested gibbons (Nomascus) were found over a large part of southern and central China up to the Yellow River. The Tonkin black crested gibbon (Black crested gibbon concolor) occurs in southern China (southwestern Yunnan) and northern Vietnam (Lào Cai, Yên Bái, Sơn La, and Lai Châu provinces), between the Black and Red Rivers. The West Yunnan black crested gibbon (N. C. Furvogaster) occurs in a small area near the Burma border, west of the Mekong, in southwestern Yunnan, southern China.

While under protection, there was still a noticeable decline in population size at Wuliangshan National Nature Reserve.

Diet and breeding

On rare occasions, it will eat fungi, insects, bird eggs and young, and small mammals such as flying squirrels. Gibbons also utilize other forms of locomotion such as bipedal walking, climbing, leaping, and diving.

In crisis

The black crested gibbon is listed as critically endangered on the IUCN Red List. An estimated 1300 to 2000 individuals are left in the wild. It was discovered that the gray langurs are suppressing the black crested gibbon's potential recovery.

Ecological corridors were put in place in the Hengduan Mountain in China to help restore connections between different groups, increase overall well-being, and decrease the risk of extinction.

CITES lists this taxon on Appendix I. Confirm the current appendix on the CITES checklist.
