Nilgiri Langur (Presbytis johni) is a glossy black monkey with a yellowish brown head. It has a long tail and is similar in size to the common Langur. It is commonly found in the
Nilgiri hills of the
Western Ghats and also in
Kodagu District in
Karnataka, Palani hills in
Tamil Nadu and
Anamalai,
Brahmagiri and Cardamom hills in
Kerala. The group size ranges from 3 to 25 individuals. The Nilgiri Langur is exclusively vegetarian, and its diet is composed mainly of mature leaves, but it also eats young leaves and fruit. At present there is a decline in the number of these animals, because of the destruction of Shola forests and due to a number of other human activities.
