Situated on the western tip of Chorao island, the sanctuary is small, just 1.78 sq km but it has much for bird watchers. Perfect for a picnic, one has to take a ferry to reach here. The mangroves here are filled with birds, enough to keep you hooked. 14 species of mangroves are here providing an ideal breeding ground for Planktons, Shrimps, tiny Crabs and small estuarine fish and they provide feeding ground for birds as well.

Migratory birds can be seen here from November to February, these include Pintail Ducks, Cormorants, Storks, Purplke Moorhen and Mallards.
