The Dusky Langur, or
Spectacled Leaf Monkey, inhabits a range of forest habitats including
coastal and riverine settings. The species feeds on succulent young leaves,
leaf shoots and occasionally forest fruits, and is thus mainly arboreal in
habits. Sometimes adults will descend to the ground at
forest margins to feed on low shrubs.
This is an easily identifiable species, with thick white eye-rings and pale
pinkish skin around the mouth, which is devoid of fur. Depending on
the amount of ambient light, its body fur can appear greyish brown, dark grey or jet
black. The fur on the crown, legs and tail is lighter. Young infants are pale yellow
to orange.
Troupe size may be up to 20 individuals. They are active in early morning and late
afternoon, but at midday can be spotted lounging in the cool of shady trees.
The species occurs in southern Myanmar, southern Thailand and Peninsular Malaysia.
