Black Crested Gibbon Nomascus concolor

Critically Endangered

Location: China, Vietnam, Laos

The Black Crested Gibbon belongs to genus Nomascus and are found in Vietnam, Laos and southern China. They are known to communicate in species-specific song when defining territory or attracting mates. They sing in regional accents to each other and form breeding pairs.

The biggest threat to the Black Crested Gibbon is destructive local forest use and hunting while selective logging and agriculture encroachment are additional threats (Geissmann et al. 2000; Jiang et al. 2006; Sun et al. 2012; Wei et al. 2017).

This species lives in subtropical and montane evergreen, semi-evergreen and deciduous forest (Fan et al. 2009c, Jiang et al. 2006) and in China it is restricted to broadleaved evergreen forests (Fan et al. 2009a). In the Wuliang and Ailao Mountains, Nomascus concolor concolor occur at altitudes ranging from 1,800 to 2,800 m (Bleisch and Chen 1991; Jiang et al. 2006; Li et al. 2011; Luo 2011) with no group occurring at elevations lower than 1,500 m (Fan pers. comm.)

Hi, I’m Palm Oil Detective’s Editor in Chief. Palm Oil Detectives is partly a consumer website about palm oil in products and partly an online community for writers, artists and musicians to showcase their work and express their love for endangered species. I have a strong voice for creatures great and small threatened by deforestation. With our collective power we can shift the greed of the retail industry and influence big palm oil to stop cutting down forests. Be bold! Be courageous! Join me and stand up for the animals with your art and your supermarket choices!
