Abstract: | The diet of a habituated group of black crested gibbon (Nomascus concolor jingdongensis) was studied from March 2005 to April 2006 in the Wuliang Mountains, central Yunnan, China. Gibbons consumed 77 different
plant species, one mammal-, two bird-, one lizard-, and two insect-species. Buds and leaves constituted 46.5% of the diet
(21.0% vine leaves and buds, 19.2% tree leaves and buds, and 6.3% epiphyte leaves). Fruits, figs and flowers accounted for
25.5, 18.6 and 9.1% of the diet, respectively. There was marked seasonal variation in dietary proportions. Fruit varied from
0.3 to 82.7%; figs from 0 to 68.2%; tree leaves and buds from 1.5 to 83.3%; vine leaves and buds from 3.1 to 61.9%; and epiphyte
leaves from 0 to 22.2% of the diet. Different food types dominated the diet in different months during the study period. The
foli-frugivorous diet and extreme seasonal variation in the diet may be related to the harsh habitat of the study group. |
