Pani Dihing Wildlife Sanctuary is a 33.93-square-kilometre (13.10 sq mi) wildlife sanctuary located in Sivasagar district, Assam. It is 22 km (14 mi) away from Sivasagar town. This protected area was established as a Bird Sanctuary in August 1999 by the Government of Assam. The sanctuary is bordered by the Brahmaputra and the Dishang rivers in the North West and south respectively. As many as 267 species of birds including 70 species of migratory birds have been identified and recorded at Pani Dihing. The common birds seen here are Bar-Headed Goose, Greylag Goose, Spot-Billed Duck, Mallards, Gadwall, Wigeon, Garganey, Shoveller, Red Crested Pochard, Common Pochard, Ferruginous Duck, Adjutant Stork, Kingfisher and many more. Although an important birding area supporting a very large population of birds, Pani Dihing has suffered on account of poaching, grazing of cattle and fishing within the sanctuary premises.
