Explanation: The Nalabana bird sanctuary is located on Nalabana Island in the Chilika lagoon area in Odisha. The Nalabana Bird Sanctuary is the core area of Chilika.

• The large Nalabana Island (Forest of Reeds) covering about 16 sq km was declared a bird sanctuary in 1987.
• The island disappears during the monsoon due to inundation, only to emerge again post-monsoon.
• Nalabana and Mangalajodi (on the banks of Chilika Lake) are the two major places in Chilika where the birds congregate.
