Vedantangal Birds Sanctuary

About 35 km south  of Chengalpattu, this is one of the most spectacular water-bird breeding grounds in India. Cormorants, egrets, herons, storks, ibises, spoonbills, grebes and pelicans come here to breed and nest for about six months from October/November to March, depending on the monsoons. At the height of the breeding season, there can be up to 30,000 birds at once. The best times to visit are early morning and late afternoon
