Eurasian teal
The Narathali lake, Raidāk and Jayanti rivers provide habitat to migratory birds like common merganser ("Mergus merganser"), Eurasian teal ("Anas crecca"), black-necked crane ("Grus nigricollis"), black stork ("Ciconia nigra"), and ferruginous pochard ("Aythya nyroca"). Two new frog species were discovered in 2006.
