The Indian rhinoceros (Rhinoceros unicornis) is a species of rhinoceros that once ranged across the entire northern part of the Indian subcontinent. As a result of habitat destruction and climatic changes, its range was gradually reduced such that, by the 19th century, it survived only in southern Nepal, northern Uttar Pradesh, northern Bihar, northern West Bengal, and in the Brahmaputra Valley in Assam. The species's range has since shrunk further, and its habitat is surrounded by human-dominated landscapes, so that in many areas, it occurs in cultivated areas, pastures, and secondary forests. It is currently listed as a vulnerable species on the IUCN Red List. This adult male Indian rhinoceros was photographed on the banks of the Gandaki River in Nepal.Photograph credit: Charles James Sharp
