Nalbana Bird Sanctuary is a 15.53 km2 (6.0 sq mi) protected areacomprised mostly of Nalbana Island (in Oriya language, Nalbana means a weed covered island), a major island near the centre of Chilka Lake. It was notified in 1987 and declared a bird sanctuary in 1973 under the Wildlife Protection Act.[1]
The island gets completely submerged during the monsoon season. As the monsoon recedes in the winter, lake levels decrease and the island is gradually exposed. Migratory and resident birds then flock to the island in large numbers to feed. During 2007, nearly 840,000 birds visited the lake, out of which 198,000 were spotted at Nalbana Island. On Jan 5, 2008, a bird census involving 85 wildlife officials counted 900,000 birds of which 450,000 were sighted in Nalabana. Recent removal of invasive fresh water weeds from the lake is stated to be a contributing factor for the higher numbers of birds.[2]
