The Mudumalai National Park and Wildlife Sanctuary Tamil, now also declared a Tiger Reserve, lies on the northwestern side of the Nilgiri Hills (Blue Mountains), in Nilgiri District, about 160 km (99 mi) north-west of Coimbatore in the westernmost part of Tamil Nadu, on the interstate boundaries with Karnataka and Kerala states in South India. Mudumalai, which means 'first hills’, is one of the first wildlife sanctuaries established in India. The sanctuary is divided into 5 ranges - Masinagudi, Thepakadu, Mudumalai, Kargudi and Nellakota. Here one can often spot herds of endangered Indian elephants, vulnerable Gaur(Indian Bison), and Chital. The sanctuary is a haven for Bengal Tigers and Indian Leopards and other threatened species. There are at least 266 species of birds in the sanctuary, including critically endangered species like the Indian White-rumped Vulture and the long-billed vulture.
