With a graceful dark face and flowing tail the Grey Langur may be mistaken for the Purple-faced Leaf monkey which also has a dark face.  They live in groups of about 20 and are found in dry lowlands where they feed on tender leaves and fruits. They intelligently congregate near Spotted Deer for extra senses to escape predators. Usually shy and peaceful towards humans. Commonly seen in Sigiriya Anuradhapura and Polonnaruwa.
