The Siberian sand plover or lesser sand plover (Charadrius mongolus) is a small wader in the plover family of birds. The spelling was commonly given as lesser sand-plover, but the official British Ornithologists' Union spelling is "lesser sand plover". The International Ornithologists' Union split the Tibetan sand plover from it and changed its vernacular name to "Siberian sand plover".[2] The genus name Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek kharadrios (χἄραδριός), a bird found in ravines and river valleys (kharadra, "ravine"); a curlew according to Liddell and Scott. The specific mongolus is Latin and refers to Mongolia, which at the time of naming referred to a larger area than the present country.[3]
Taxonomy
The Siberian sand plover was previously considered conspecific with the Tibetan sand plover. There are five races in the species complex, and the large east Asian forms include C. m. mongolus and C. m. stegmanni, is the current defination of Siberian sand plover, Charadrius mongolus. The Tibetan Plateau form Charadrius atrifrons is now known as Tibetan sand plover, including the three races atrifrons, pamirensis and schaeferi.
A study published in 2022 proposed that the "mongolus" group is a sister group of the greater sand plover, and "atrifrons" group is a sister group of them also. Therefore a taxonomic split of the lesser sand plover is needed. The authors suggested new scientific and common English names for them:[4]
- Siberian sand plover (Charadrius mongolus), C. m. mongolus and C. m. stegmanni;
- Tibetan sand plover (Charadrius atrifrons), C. a. atrifrons, C. a. pamirensis and C. a. schaeferi;
- Desert sand plover (Charadrius leschenaultii), currently greater sand plover.
IOC accepted the split and renaming of the lesser sand plover in 2023, while the greater sand plover retains its common name.[2]
Distribution
It breeds discontinuously across 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 and southeast Asia.[2]
Description
This chunky plover is long-legged and long-billed. Breeding males have grey backs and white underparts. The breast, forehead and nape are chestnut, and there is a black eye mask. The female is duller, and winter and juvenile birds lack the chestnut, apart from a hint of rufous on the head. Legs are dark and the bill black.
In all plumages, this species is very similar to the greater sand plover, Charadrius leschenaultii. Separating the species may be straightforward in mixed wintering flocks on an Indian beach, where the difference in size and structure is obvious; it is more difficult to identify a lone vagrant to western Europe, where both species are very rare. The problem is compounded in that the Middle Eastern race of greater sand plover is the most similar to the lesser. The lesser usually has darker legs, a white forehead, and a more even white wing bar than the greater.
Ecology
The Siberian sand plover feeds on insects, crustaceans and annelid worms, which are obtained by a run-and-pause technique, rather than the steady probing of some other wader groups. This species takes fewer steps and shorter pauses than the greater sand plover when feeding.
The flight call is a hard trill.
The Siberian sand plover is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
Identification
Size is one of the factors distinguishing a lesser sand plover from a greater sand plover, with the lesser being slightly smaller. However, it is not easy to rely on size alone especially when seen individually. The length of the bill is another distinguishing feature, with the lesser generally having a shorter bill compared to a greater. The colour of the legs in a lesser sand plover is generally darker, ranging from black to grey, while in a greater sand plover it is much paler, ranging from grey to yellowish.[needs update]
