BNS (Ephippiorhynchus asiaticus) is categorised as a near-threatened species on the Red List of the International Union for Conservation of Nature (IUCN) due to its declining population trend globally largely on account of habitat loss.
It is considered a rare bird in Gujarat due to its small population size.
The Khijadiya Bird Sanctuary near Jamnagar and the Marine National Park along the coast of Jamnagar and Devbhumi Dwarka district harbour the largest population of BNS in Gujarat.
The species has been breeding successfully in Khijadiya, a Ramsar site, as well as in the coastal wetland area.
Birds of this species are also sighted in Bharuch, Vadodara, Polo Forest in Sabarkantha and Kutch. They are also occasionally sighted at Nal Sarovar Bird Sanctuary, another Ramsar site, in the state.
Porbandar is a major wintering ground for the demoiselle crane population that breeds in central Asia.
