Hybridisation In Shorebirds
Hybridisation in shorebirds has been proven on only a small number of occasions; however, many individual shorebirds have been recorded by birdwatchers worldwide that do not fit the characters of known species. Many of these have been suspected of being hybrids. In several cases, shorebird hybrids have been described as new species before their hybrid origin was discovered. Compared to other groups of birds (such as gulls), only a few species of shorebirds are known or suspected to hybridise, but nonetheless, these hybrids occur quite frequently in some cases. Hybrids in the Scolopaci (sandpipers and allies) "Cooper's" and "Cox's" sandpipers An apparently new sandpiper species ("Cooper's sandpiper ''Tringa''/''Calidris cooperi''") was described in 1858 based on a specimen collected in 1833 on Long Island, New York. A similar bird was collected in 1981 at Stockton, New South Wales, Australia. These are probably hybrids between the curlew sandpiper (''Calidris ferruginea'') and the ...

Wader
245px, A flock of Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the smaller species found ...

Dunlin
The dunlin (''Calidris alpina'') 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. It is a circumpolar breeder in Arctic or subarctic regions. Birds that breed in western Europe are short-distance migrants largely staying on western and southern European and northwest African coasts; those breeding in far northern Europe and Asia are long-distance migrants, wintering south to Africa, southeast and west Asia. Birds that breed in Alaska and the Canadian Arctic migrate short distances to the Pacific and Atlantic coasts of North America, although those nesting in northern Alaska overwinter in Asia. Taxonomy The dunlin was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa alpina''. Linnaeus spec ...

New Zealand
New Zealand () is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and List of islands of New Zealand, over 600 smaller islands. It is the List of island countries, sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The Geography of New Zealand, country's varied topography and sharp mountain peaks, including the Southern Alps (), owe much to tectonic uplift and volcanic eruptions. Capital of New Zealand, New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and subsequently developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Island Pied Oystercatcher
The South Island oystercatcher or South Island pied oystercatcher (''Haematopus finschi'') is one of two common oystercatcher species found in New Zealand. Its name is often contracted to the acronym "SIPO" (rhyming with "typo"). The indigenous Māori name is . The scientific name commemorates the German ethnographer, naturalist and colonial explorer Friedrich Hermann Otto Finsch (8 August 1839 – 31 January 1917, Braunschweig).Jobling, James A. (2010). Bloomsbury Publishing, ed. The Helm dictionary of scientific bird names from aalge to zusii. Londres: Christopher Helm. p. 159. ISBN 1408133261. Description The South Island oystercatcher is easily identifiable as a pied oystercatcher – a large wader with striking black and white plumage, long red-orange bill, and red legs. It is distinguished from the pied morph of the variable oystercatcher by a white lower back, more white on the wing, and a demarcation line of black and white further forward on the breast, and from the ...

Variable Oystercatcher
The variable oystercatcher (''Haematopus unicolor'') is a species of wader in the family Haematopodidae. It is Endemism, endemic to New Zealand. The Māori name is tōrea-pango. They are also known as 'red bills'. Description "Variable" refers to the frontal plumage, which ranges from pied through mottled to all black. They are polymorphic meaning they have different genetic variants. These color differences are attributed to the latitude of the habitat, where the northernmost oystercatchers have significantly more white on their bodies than those of southern origin. All Stewart Island variable oystercatchers are black. They have pink legs, an orange eye ring and orange-red beaks. Similar to a needle in shape, the bill is thin and long, and darkens to a deep red color during the breeding season. Males are around 678 grams and females slightly larger at around 724 grams. Length of individuals range from 42 to 47 cm from beak to tail and have a short, sturdy body with a thick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Black Oystercatcher
The black oystercatcher (''Haematopus bachmani'') is a conspicuous black bird found on the shoreline of western North America, ranging from the Aleutian Islands of Alaska to the coast of the Baja California peninsula. It is the only representative of the oystercatcher family (Haematopodidae) over most of its range, overlapping slightly with the American oystercatcher (''H. palliatus'') on the coast of Baja California. Within its range it is most commonly referred to as the black oystercatcher, although this name is also used locally for the blackish oystercatcher and the African oystercatcher. Its scientific name was derived by John James Audubon from that of his friend John Bachman. Although the species is not considered threatened, its global population is estimated between 8,900–11,000. It is a species of high conservation concern throughout its range (U.S., Canadian, Alaskan, and Northern & Southern Pacific Shorebird Conservation Plans), a keystone indicator species al ...

Purple Sandpiper
The purple sandpiper (''Calidris maritima'') is a small shorebird in the sandpiper family Scolopacidae. This is a hardy sandpiper that breeds in the arctic and subarctic regions of Eurasia and North America and winters further south on the Atlantic coast. Taxonomy The purple sandpiper was formally described in 1764 by the Danish zoologist Morten Thrane Brünnich and given the binomial name ''Tringa maratina''. This species was formerly placed in the genus ''Erolia'', but is now placed with 23 other sandpipers in the genus ''Calidris'' that was introduced in 1804 by the German naturalist Blasius Merrem. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific epithet ''maritima'' is from Latin and means "of the sea", from ''mare'', "sea". The purple sandpiper is treated as monotypic: no subspecies are recognised.
