Red-shanked douc range |
The red-shanked doucs live in fission-fusion, multilevel societies that have a mean of 18 individuals per band.[9] They are folivorous and consume mainly Acacia pruinescens, Ficus racemosa, Millettia nigrescens, Zanthoxylum avicennae and Castanopsis ceratacantha.[10] Their four-chambered stomachs that allow for bacterial fermentation help them with their high fiber diet.[11] In captivity, it was found that they use brachiation as a mode of locomotion approximately half the time while in the wild, it is only 18% of the time.[12] Female doucs have an average menstrual cycle of 26.4 days and remain pregnant for 165-210 days.[6][13]
