Explanation: Named after the village – ‘Nelapattu’, located just adjoining in the Sanctuary in Nellore district of Andhra Pradesh is this wetland mainly for migratory water birds.

• The farmers of Nelapattu and their bird visitors have a symbiotic relationship. The bird ‘Guano’ (waste matter) acts as a natural fertilizer to the crops and the villagers in turn protect the birds.
• The largest breeding ground for the Grey pelicans in South East Asia, with approximately 1,500 pelicans breeding every year.
• The local people of Nelapattu, Muchalagunta, Mylangam, etc; protect the birds as “celestial birds”, as their arrival brings good rains and good crops.
