The pied avocet (Recurvirostra avosetta) is a large black and white wader in the avocet and stilt family, Recurvirostridae. They breed in temperate Europe and across the Palearctic to Central Asia then on to the Russian Far East. It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England. The pied avocet is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
The pied avocet was one of the many bird species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, where it was given the binomial name of Recurvirostra avosetta. [2] This species gets its English and scientific names from the Venetian word avosetta. It appeared first in Ulisse Aldrovandi's Ornithologia (1603). [3] While the name may refer to black and white outfits once worn by European advocates or lawyers, the actual etymology is uncertain. [3] Other common names include black-capped avocet, Eurasian avocet or just avocet. [4]
It is one of four species of avocet that make up the genus Recurvirostra. [5] The genus name is from Latin recurvus, "curved backwards" and rostrum, "bill". [6] A 2004 study combining genetics and morphology showed that it was the most divergent species in the genus. [7]
The pied avocet is a striking white wader with bold black markings. Adults have white plumage except for a black cap and black patches in the wings and on the back. They have long, upturned bills and long, bluish legs. It is approximately 16.5–17.75 in (41.9–45.1 cm) in length of which the bill is approximately 2.95–3.35 in (7.5–8.5 cm) and the legs are approximately 3–4 in (7.6–10.2 cm). Its wingspan is approximately 30–31.5 in (76–80 cm). [8] Males and females look alike. The juvenile resembles the adult but with more greyish and sepia tones.
The call of the avocet is a far-carrying, liquid, melodious kluit kluit. [8]
These birds forage in shallow brackish water or on mud flats, often scything their bills from side to side in water (a feeding technique that is unique to the avocets [9] ). They mainly eat crustaceans and insects.
Their breeding habitat is shallow lakes with brackish water and exposed bare mud. They nest on open ground, often in small groups, sometimes with other waders. Three to five eggs are laid in a lined scrape or on a mound of vegetation.
The pied avocet was extirpated as a breeding species in Great Britain by 1840. [10] Its successful recolonisation at Minsmere, Suffolk, in 1947 led to its adoption as the logo of the Royal Society for the Protection of Birds. [8] The pied avocet has spread inland and northwards and westwards in Britain since then and it has bred in Wales [11] and in Scotland in 2018 at Skinflats. [12] Avocets have been sighted wintering at Browhouses, Dumfries and Galloway.
The red-backed shrike is a carnivorous passerine bird and member of the shrike family, Laniidae. Its breeding range stretches from Western Europe east to central Russia. It is migratory and winters in the eastern areas of tropical Africa and southern Africa.
The four species of avocets are a genus, Recurvirostra, of waders in the same avian family as the stilts. The genus name comes from Latin recurvus, 'curved backwards' and rostrum, 'bill'. The common name is thought to derive from the Italian (Ferrarese) word avosetta. Francis Willughby in 1678 noted it as the "Avosetta of the Italians".
The gadwall is a common and widespread dabbling duck in the family Anatidae.
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 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 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 shelduck is a waterfowl species of the shelduck genus, Tadorna. It is widespread and common in the Euro-Siberian region of the Palearctic, mainly breeding in temperate and wintering in subtropical regions; in winter, it can also be found in the Maghreb.
The common redshank or simply redshank is a Eurasian wader in the large family Scolopacidae.
The American avocet is a large wader in the avocet and stilt family, Recurvirostridae, found in North America. It spends much of its time foraging in shallow water or on mud flats, often sweeping its bill from side to side in water as it seeks crustacean and insect prey.
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 dunlin is a small wader in the genus Calidris. 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 green sandpiper is a small wader (shorebird) of the Old World.
The Eurasian oystercatcher also known as the common pied oystercatcher, or just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It has striking black and white plumage, a long straight orange-red bill, red eyes and relatively short dull pink legs. The sexes are similar in appearance but the bill of the female is longer than that of the male.
The Eurasian or common whimbrel, also known as the white-rumped whimbrel in North America, is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific.
The Eurasian spoonbill, or common spoonbill, is a wading bird of the ibis and spoonbill family Threskiornithidae, native to Europe, Africa and Asia. The species is partially migratory with the more northerly breeding populations mostly migrating south for the winter.
The common snipe is a small, stocky wader native to the Old World.
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 genus Tringa.
The red-necked phalarope, also known as the northern phalarope and hyperborean 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, winters at sea on tropical oceans.
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 collared pratincole, also known as the common pratincole or red-winged pratincole, is a wader in the pratincole family, Glareolidae. As with other pratincoles, it is native to the Old World.
The velvet scoter is a large sea duck, which breeds over the far north of Europe and the Palearctic west of the Yenisey basin. The genus name is derived from Ancient Greek melas "black" and netta "duck". The species name is from the Latin fuscus "dusky brown".
