The Nilgiri langur (Trachypithecus johnii) is a lutung found in the Nilgiri Hills of the Western Ghats in South India.
Its range also includes Kodagu in Karnataka, Kodayar Hills in Tamil Nadu and many other hilly areas in Kerala and Tamil Nadu.
It has glossy black fur on its body and golden brown fur on its head. Females have a white patch of fur on the inner thigh. It lives in troops of five to 16 monkeys.
The favourite haunts of the Nilgiri Langur are the sholas, which are dense evergreen forests occupying the watercourses or folds in high elevation grasslands.
Primarily vegetarian, their diet comprises of leaves, flowers, buds, seeds, bark and stem of various plants. Preferring new leaves, it feeds on a variety of plants depending on the season.
Like the Common Langur, the whooping call of the Nilgiri Langur is very distinctive though quite different in its resonance. Normally the whooping call of one male elicits similar booming whoops from neighbouring males and soon the forest seems to echo with these calls. [Video] The whooping call of the Nilgiri Langur
