The Siberian sand plover (Anarhynchus mongolus) is a small wader in the plover family of birds. The International Ornithologists' Union split the Tibetan sand plover from the lesser sand plover and changed its vernacular name to Siberian sand plover. [2] 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]
The Siberian sand plover and the Tibetan sand plover were previously considered to belong to the same species known as the "lesser sand plover", consisting of five races within the species complex. However, a study published in 2022 suggested that the "mongolus" group (currently identified as the Siberian sand plover) within the lesser sand plover is actually the sister group of the greater sand plover. Additionally, the "atrifrons" group (representing the Tibetan sand plover) is the sister group of the monophyletic group formed by the "mongolus" group and the greater sand plover.

This means that the lesser sand plover is paraphyletic. Therefore a taxonomic revision was needed. The authors suggested new scientific and common English names for them. [4] The large East Asian forms mongolus and stegmanni are currently identified as the Siberian sand plover, Anarhynchus mongolus; and the Tibetan Plateau form is now known as the Tibetan sand plover, Anarhynchus atrifrons, which includes the three races atrifrons, pamirensis and schaeferi.
IOU accepted the split and renaming of the lesser sand plover in 2023. [2]
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.
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]
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.
Size is one of the factors distinguishing a Siberian sand plover from a greater sand plover, with the Siberian 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 Siberian generally having a shorter bill compared to a greater. The colour of the legs in a Siberian 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 ]
The black-winged stilt is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopussensu lato. Meanwhile, the black-necked and white-backed stilts both inhabit the Americas; the pied stilt ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species.
The common ringed plover or ringed plover is a small plover that breeds across much of northern Eurasia, as well as Greenland. 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 a bird found in ravines and river valleys. The specific hiaticula is Latin and has a similar meaning to the Greek term, coming from hiatus, "cleft" and -cola, "dweller".
The little ringed plover is a small plover. 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 a bird found in river valleys. The specific dubius is Latin for doubtful, since Sonnerat, writing in 1776, thought this bird might be just a variant of common ringed plover.
The snowy plover is a small shorebird found in the Americas. It is a member of the bird family Charadriidae, which includes the plovers, dotterels, and lapwings. The snowy plover was originally described by John Cassin in 1858, but was classified as a subspecies of the Kentish plover in 1922. Since 2011, the snowy plover has been recognized as a distinct species based on genetic and anatomical differences from the Kentish plover. Two or three subspecies are recognized, distributed along the Pacific coast of North America, Ecuador, Peru, and Chile, in several inland areas of the US and Mexico, along the Gulf Coast, and on Caribbean islands. The coastal populations consist of both residential and migratory birds, whereas the inland populations are mostly migratory. It is one of the best studied endemic shorebirds of the Americas, and one of the rarest.
The Eurasian dotterel, also known in Europe as just dotterel, is a small wader in the plover family of birds. It is the only species placed in the genus Eudromias.
The greater sand plover is a small wader in the plover family of birds. The spelling is often given as "greater sandplover" or "greater sand-plover", but the official IOC and British Ornithologists' Union spelling is "Greater Sand Plover". The specific leschenaultii commemorates the French botanist Jean Baptiste Leschenault de la Tour. Like most other species in the genus Anarhynchus, it was until recently included in the genus Charadrius.
The Caspian plover is a wader in the plover family of birds. The specific asiaticus is Latin and means "Asian", although in binomials it usually means the type locality was India.
Wilson's plover is a small bird of the family Charadriidae.
Kittlitz's plover is a small shorebird in the family Charadriidae that breeds near coastal and inland saltmarshes, sandy or muddy riverbanks or alkaline grasslands with short vegetation. It is native to much of Sub-Saharan Africa, the Nile Delta and Madagascar. It is thought to be mainly polygamous and has monomorphic plumage.
The collared plover is a small shorebird in the plover family, Charadriidae. It lives along coasts and riverbanks of the tropical to temperate Americas, from central Mexico south to Chile and Argentina.
The double-banded plover, known as the banded dotterel or pohowera in New Zealand, is a species of bird in the plover family. Two subspecies are recognised: the nominate Charadrius bicinctus bicinctus, which breeds throughout New Zealand, including the Chatham Islands, and Charadrius bicinctus exilis, which breeds in New Zealand's subantarctic Auckland Islands.
The wrybill or ngutuparore is a species of plover endemic to New Zealand. It is the only species of bird in the world with a beak that is bent sideways in one direction, always to the right. A 2015 study found it to be within the Charadrius clade, with other New Zealand plovers its closest relatives; the nearest being the New Zealand dotterel or New Zealand plover, and then the double-banded plover or banded dotterel.
The three-banded plover, or three-banded sandplover, is a small wader. This plover is resident and generally sedentary in much of East Africa, southern Africa and Madagascar. It occurs mainly on inland rivers, pools, lakes and pans, frequenting their exposed shores. This species is often seen as single individuals, but it will form small flocks. It hunts by sight for insects, worms and other invertebrates. Three-banded plovers have a sharp whistled weeet-weet call. Its larger and darker-plumaged sister species, Forbes's plover, replaces it in West Africa and in the moist tropics. The two species have largely allopatric breeding ranges. Both species present a distinctively elongated profile, due to their proportionally long tail and wings.
Anarhynchus is a genus of plovers consisting of 24 species.
The western snowy plover is a small wader in the plover bird family. They are currently federally listed under the U.S. Endangered Species Act as Threatened. Human activity, habitat loss and predation are the biggest contributors to population degradation. A recovery plan was approved under the US Fish and Wildlife Service in 2007. Recovery actions and monitoring are crucial for these vulnerable seabirds.
The Tibetan sand plover is a small wader in the plover family of birds, breeds in Pamir Mountains, Tian Shan, Tibetan Plateau and south Mongolia, winters in east and south Africa, south, east and southeast Asia.
