The grey plover or black-bellied plover (Pluvialis squatarola) is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding. [2]
The grey plover was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Tringa squatarola. [3] It is now placed with three other plovers in the genus Pluvialis that was introduced by the French onithologist Mathurin Jacques Brisson in 1760. [4] [5] The genus name is Latin and means relating to rain, from pluvia, "rain". It was believed that they flocked when rain was imminent. The species name squatarola is a Latinised version of Sgatarola, a Venetian name for some kind of plover. [6]
The English common name used for this species differs in different parts of the world. It is generally known as "grey plover" in the Old World and "black-bellied plover" in the New World. [7]
Three subspecies are recognised: [5]
The grey plover is 27–30 cm (11–12 in) long with a wingspan of 71–83 cm (28–33 in) and a weight of 190–280 g (6.7–9.9 oz) (up to 345 g (12.2 oz) in preparation for migration). In spring and summer (late April or May to August), adults are spotted black and white on the back and wings. The face and neck are black with a white border; they have a black breast and belly and a white rump. The tail is white with black barring. The bill and legs are black. They moult to winter plumage in mid August to early September and retain this until April; this being a fairly plain grey above, with a grey-speckled breast and white belly. The juvenile and first-winter plumages, held by young birds from fledging until about one year old, are similar to the adult winter plumage but with the back feathers blacker with creamy white edging. In all plumages, the inner flanks and axillary feathers at the base of the underwing are black, a feature which readily distinguishes it from the other three Pluvialis species in flight. On the ground, it can also be told from the other Pluvialis species by its larger (24–34 mm, 0.94–1.34 in), heavier bill. [2] [8]
Their breeding habitat is Arctic islands and coastal areas across the northern coasts of Alaska, Canada, and Russia. They nest on the ground in a dry open tundra with good visibility; the nest is a shallow gravel scrape. Four eggs (sometimes only three) are laid in early June, with an incubation period of 26–27 days; the chicks fledge when 35–45 days old. [2] [8]
They migrate to winter in coastal areas throughout the world. In the New World they winter from southwest British Columbia and Massachusetts south to Argentina and Chile, in the western Old World from Ireland and southwestern Norway south throughout coastal Africa to South Africa, and in the eastern Old World, from southern Japan south throughout coastal southern Asia and Australia, with a few reaching New Zealand. Most of the migrants to Australia are female. It makes regular non-stop transcontinental flights over Asia, Europe, and North America, but is mostly a rare vagrant on the ground in the interior of continents, only landing occasionally if forced down by severe weather, or to feed on the coast-like shores of very large lakes such as the Great Lakes, where it is a common passage migrant. [2] [8] [9]
Young birds do not breed until two years old; they typically remain on the wintering grounds until their second summer. [2] [8]
They forage for food on beaches and tidal flats, usually by sight. The food consists of small molluscs, polychaete worms, crustaceans, and insects. It is less gregarious than the other Pluvialis species, not forming dense feeding flocks, instead feeding widely dispersed over beaches, with birds well spaced apart. They will however form dense flocks on high tide roosts. [2] [8]
The International Union for Conservation of Nature (IUCN) has judged that the threat to the grey plover is of "Least concern". [1] It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. [10]
The northern lapwing, also known as the peewit or pewit, tuit or tewit, green plover, or pyewipe or just lapwing, is a bird in the lapwing subfamily. It is common through temperate Eurosiberia.
The northern shoveler, known simply in Britain as the shoveler, is a common and widespread duck. It breeds in northern areas of Europe and across the Palearctic and across most of North America, wintering in southern Europe, the Indian subcontinent, Southeast Asia, Central, the Caribbean, and northern South America. It is a rare vagrant to Australia. In North America, it breeds along the southern edge of Hudson Bay and west of this body of water, and as far south as the Great Lakes west to Colorado, Nevada, and Oregon.
The gadwall is a common and widespread dabbling duck in the family Anatidae.
The Eurasian wigeon or European wigeon, also known as the widgeon or the wigeon, is one of three species of wigeon in the dabbling duck genus Mareca. It is common and widespread within its Palearctic range.
The Eurasian teal, common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal.
The ruddy turnstone is a small cosmopolitan wading bird, one of two species of turnstone in the genus Arenaria.
The garganey is a small dabbling duck. It breeds in much of Europe and across the Palearctic, but is strictly migratory, with the entire population moving to southern Africa, India, Bangladesh and Australasia during the winter of the Northern hemisphere, where large flocks can occur. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Like other small ducks such as the Eurasian teal, this species rises easily from the water with a fast twisting wader-like flight.
The common redshank or simply redshank is a Eurasian wader in the large family Scolopacidae.
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 dunlin is a small wader, formerly sometimes separated with the other "stints" in the genus Erolia. The English name is a dialect form of "dunling", first recorded in 1531–1532. It derives from dun, "dull brown", with the suffix -ling, meaning a person or thing with the given quality.
The European golden plover, also known as the European golden-plover, Eurasian golden plover, or just the golden plover within Europe, is a relatively large species of plover. This species is similar to two other golden plovers: the American golden plover, Pluvialis dominica, and Pacific golden plover, Pluvialis fulva, which are both smaller, slimmer and relatively longer-legged than European golden plover, and both have grey rather than white axillary feathers.
The Pacific golden plover is a migratory shorebird that breeds during Alaska and Siberia summers. During nonbreeding season, this medium-sized plover migrates widely across the Pacific.
The common sandpiper is a small Palearctic wader. This bird and its American sister species, the spotted sandpiper, make up the genus Actitis. They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize. Hybridization has also been reported between the common sandpiper and the green sandpiper, a basal species of the closely related shank genus Tringa.
The bar-tailed godwit is a large and strongly migratory wader in the family Scolopacidae, which feeds on bristle-worms and shellfish on coastal mudflats and estuaries. It has distinctive red breeding plumage, long legs, and a long upturned bill. Bar-tailed godwits breed on Arctic coasts and tundra from Scandinavia to Alaska, and overwinter on coasts in temperate and tropical regions of Australia and New Zealand. The migration of the subspecies Limosa lapponica baueri across the Pacific Ocean from Alaska to New Zealand is the longest known non-stop flight of any bird, and also the longest journey without pausing to feed by any animal. The round-trip migration for this subspecies is over 29,000 km (18,020 mi).
The black-tailed godwit is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. It is a member of the godwit genus, Limosa. There are four subspecies, all with orange head, neck and chest in breeding plumage and dull grey-brown winter coloration, and distinctive black and white wingbar at all times.
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 phalarope or grey phalarope is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, migrates mainly on oceanic routes, wintering at sea on tropical oceans.
The brambling is a small passerine bird in the finch family Fringillidae. It has also been called the cock o' the north and the mountain finch. It is widespread and migratory, often seen in very large flocks.
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.
The Cape wagtail, also known as Wells's wagtail, is a small insectivorous bird which is widespread in southern Africa. It frequents water's edge, lawns and gardens. It is a mostly resident, territorial species, but has been known to undertake limited altitudinal migration or form flocks outside of the breeding season. Like other wagtails they are passerine birds of the family Motacillidae, which also includes the pipits and longclaws.
