The greater sand plover (Anarhynchus leschenaultii) 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". [2] [3] The specific leschenaultii commemorates the French botanist Jean Baptiste Leschenault de la Tour. [4] Like most other species in the genus Anarhynchus , it was until recently included in the genus Charadrius . [2]

Distribution

It breeds in the semi-deserts of Turkey and eastwards through Central Asia, where it nests in a bare ground scrape. This species is strongly migratory, wintering on sandy beaches in East Africa, South Asia and Australasia. It is a rare vagrant in western Europe, where it has been recorded as far west as Iceland. It has been recorded twice in North America, the most recent being on 14 May 2009 in Jacksonville, Florida. [5]

Subspecies

There are three subspecies: [2] [6] [7]

Description

This chunky plover is 19–22 cm long, slightly larger than a common ringed plover, and is conspicuously long-legged and thick-billed. Breeding males have sandy buff backs and white underparts. The breast, forehead and nape are variably orange in summer, and there is a black eye mask in summer. The female is duller and greyer, and winter and juvenile birds are browner, apart from a hint of rufous on the head. The legs are greenish-yellow and the bill black. [6]

In all plumages, it is very similar to its close relatives Siberian sand plover A. mongolus and Tibetan sand plover A. atrifrons. 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 another thing altogether to identify a lone vagrant to western Europe, where both species are very rare. The problem is compounded in that the southwest Asian subspecies of the greater is the most similar to the other two species in its smaller bill.

Ecology

Its food consists of insects, crustaceans and annelid worms, which are obtained by a run-and-pause technique, rather than the steady probing of some other wader groups.

Its flight call is a soft trill.

The greater sand plover is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

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.

<span class="mw-page-title-main">Common ringed plover</span> Species of bird

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 red-necked stint is a small migratory wader. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific ruficollis is from Latin rufus, "red" and collum, "neck".

<span class="mw-page-title-main">Snowy plover</span> Species of bird

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.

<span class="mw-page-title-main">Three-banded plover</span> Species of bird

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.

<span class="mw-page-title-main">Kentish plover</span> Species of bird

The Kentish plover is a small wader of the family Charadriidae that breeds on the shores of saline lakes, lagoons, and coasts, populating sand dunes, marshes, semi-arid desert, and tundra. Both male and female birds have pale plumages with a white underside, grey/brown back, dark legs and a dark bill; however, additionally the male birds also exhibit very dark incomplete breast bands, and dark markings either side of their head, therefore the Kentish plover is regarded as sexually dimorphic.

<span class="mw-page-title-main">Long-billed plover</span> Species of bird

The long-billed plover is a species of wading bird in the family Charadriidae. It can be found in Bangladesh, Bhutan, Brunei, Cambodia, China, Hong Kong, India, Indonesia, Japan, Laos, Malaysia, Mongolia, Myanmar, Nepal, North Korea, Russia, South Korea, Sri Lanka, Taiwan, Thailand, and Vietnam. The long-billed plover is a migratory bird, so it breeds and spends the winter in different parts of its range. This bird can often be spotted along the shores of rivers, streams, in wetlands, and rice fields. It forages on the shoreline primarily for aquatic insects, insect larvae, and other invertebrates. It is difficult to distinguish between male and female individuals because of their similar plumage. The breeding season starts at the end of February or early March and ends in July. A male and a female forms a monogamous pair and maintains their territory throughout the breeding season. A global population survey in 2016 assessed the long-billed plover as a species of least concern on the International Union for Conservation of Nature (IUCN) Red List.
