The western black crested gibbon is a long-armed, tailless ape showing pronounced adult color differences. Mature males are predominantly black and possess an upright crown crest, whereas females develop a yellowish or buff coat with contrasting dark areas on the crown and underside. Like other gibbons, it has elongated hands and arms suited to rapid arm-swinging through the canopy. Its recognized range covers southwestern China, northern Vietnam and northwestern Laos.

Black crested gibbons are diurnal and arboreal, living in small social groups that maintain territories with loud calls and coordinated songs. Research in Yunnan found a seasonally variable diet in which leaves and fruit received similar feeding time; figs, buds and flowers became important at different times of year, while insects, eggs and other small organisms were also eaten. Groups may remain for several days in food-rich valleys before crossing less productive forest. (Animal Diversity Web)
