The Vehanthangal Bird Sanctuary is one of the most spectacular water bird breeding grounds in India. Cormorants, ergrets, 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 (December and January), you can see up to 30,000 birds at once. Many other species of migratory birds also visit the sanctuary. The best times to visit are early morning and late afternoon.
