Is a small wader in the plover family of birds. There are five races, and the large east Asian forms, C. m. mongolus and C. m. stegmanni, are sometimes given specific status as Mongolian plovers, Charadrius mongolus. If the taxonomic split is accepted, lesser sand plover as then defined becomes Charadrius atrifrons, including the three races atrifrons, pamirensis and schaeferi. It breeds above the tree line in the Himalayas and discontinuously across to bare coastal plains in north-eastern Siberia, with the Mongolian plover in the eastern part of the range; it has also bred in Alaska. It nests in a bare ground scrape, laying three eggs. This species is strongly migratory, wintering on sandy beaches in east Africa, south Asia and Australasia. In Labuan Island it is a common view of this waders during their migration season.
