Site description A 60 km stretch of the River Ganga extending from Sultanganj, eastward to Kahalgaon has been notified as the Vikramshila Gangetic Dolphin Sanctuary. During monsoon, the river inundates a vast floodplain and the river course also changes a bit. There are many small sandbars inhabited by birds. They serve as breeding grounds for many birds, especially the section from Sultamour to Bhagalpur, a 36 km stretch, which seems to be a paradise for birds and other aquatic animals.
AVIFAUNA: This site has been selected as an IBA due to the presence of hundreds of Indian Skimmers Rynchops albicollis. Globally threatened species such as the Greater Adjutant Leptoptilos dubius and Lesser Adjutant L. javanicus are also present. Other storks present are the Black Ciconia nigra, Black-necked Ephippiorhynchus asiaticus, White-necked Ciconia episcopus, and the Asian Openbill Anastomus oscitans. The Sanctuary is rich in waders. Common Crane Grus grus, Eurasian Spoonbill Platalea leucorodia and various ducks are also seen here.
OTHER KEY FAUNA: The River Ganga is the lifeline of north India and the Gangetic Dolphin Platanista gangetica epitomizes its life and the wealth of biodiversity in India. This is the only Dolphin Sanctuary to be declared in India. Listed by IUCN as Endangered, included in Appendix-II of CITES, and placed in Schedule I of the Indian Wildlife (Protection) Act, 1972, the dolphin enjoys a high level of protection, nationally and internationally. Yet its numbers continue to decline due to continuing developmental pressures on its habitat.
