Oystercatcher
The oystercatchers are a group of waders forming the family Haematopodidae, which has a single genus, ''Haematopus''. They are found on coasts worldwide apart from the polar regions and some tropical regions of Africa and South East Asia. The exceptions to this are the Eurasian oystercatcher, the South Island oystercatcher, and the Magellanic oystercatcher, which also breed inland, far inland in some cases. In the past there has been a great deal of confusion as to the species limits, with discrete populations of all black oystercatchers being afforded specific status but pied oystercatchers being considered one single species.Hockey, P (1996).

Eurasian Oystercatcher
The Eurasian oystercatcher (''Haematopus ostralegus'') also known as the common pied oystercatcher, or palaearctic oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It is the most widespread of the oystercatchers, with three races breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. The extinct Canary Islands oystercatcher (''Haematopus meadewaldoi''), formerly considered a distinct species, may have actually been an isolated subspecies or distinct population of the Eurasian oystercatcher. This oystercatcher is the national bird of the Faroe Islands. Taxonomy The Eurasian oystercatcher was listed by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Haemotopus ostralegus''. The genus name ''Haematopus'' combines the Ancient Greek ''haima'' αἳμα meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Oystercatcher
The American oystercatcher (''Haematopus palliatus''), occasionally called the American pied oystercatcher, is a member of family Haematopodidae. Originally called the "sea pie", it was renamed in 1731 when naturalist Mark Catesby observed the bird eating oysters. The current population of American oystercatchers is estimated to be 43,000. There are estimated to be 1,500 breeding pairs along the Atlantic and Gulf Coasts of the US. The bird is marked by its black and white body and a long, thick orange beak. Description The American oystercatcher has distinctive black and white plumage and a long, bright orange beak. The head and breast are black and the back, wings and tail greyish-black. The underparts are white, as are feathers on the inner part of the wing which become visible during flight. The irises are yellow and the eyes have orange orbital rings. The legs are pink. Adults are between in length. Distribution The American oystercatcher is found on the Atlantic coast o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Oystercatcher
The variable oystercatcher (''Haematopus unicolor'') is a species of wader in the family Haematopodidae. It is endemic to New Zealand. The Maori name is torea-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 neck. Va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pied Oystercatcher
The pied oystercatcher (''Haematopus longirostris'') is a species of oystercatcher. It is a wading bird native to Australia and commonly found on its coastline. The similar South Island pied oystercatcher (''H. finschi'') occurs in New Zealand. Description The name "oystercatcher" is something of a misnomer for this species, because they seldom eat oysters, which are found mainly on rocky coastlines. Pied oystercatchers frequent sandy coastlines, where they feed mainly on bivalve molluscs, which are prised apart with their specially adapted bill. These adaptations allow the Pied oystercatchers to slip their bills between the ventral edges of these shelled organisms, further allowing them to sever the shells and reach the edible flesh inside. This Australian species is easily recognized by the characteristic 5–8 cm long orange-red beak, slender pink legs and black and white plumage. With the wings extended, a white wing-stripe is also visible. The male and female sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sooty Oystercatcher
The sooty oystercatcher (''Haematopus fuliginosus'') is a species of oystercatcher. It is a wading bird endemic to Australia and commonly found on its coastline. It prefers rocky coastlines, but will occasionally live in estuaries. All of its feathers are black. It has a red eye, eye ring and bill, and pink legs. Taxonomy John Gould described the sooty oystercatcher in 1845. Its species name is the Latin adjective ''fuliginosus'', "sooty". Two subspecies are recognised, the nominate from the coastline of southern Australia and subspecies ''ophthalmicus'' from northern Australia. The southern subspecies is larger and heavier than the northern. The northern one, with a more yellowish eye ring, is found from the Kimberleys across the top of the country to Mackay in central Queensland. There is considerable overlap, as the southern subspecies has been found up to Cape York. Subspecies ''ophthalmicus'' has been thought distinctive enough to warrant species status and needs further in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magellanic Oystercatcher
The Magellanic oystercatcher (''Haematopus leucopodus'') is a species of wader in the family Haematopodidae. It is found in Argentina, Chile and the Falkland Islands in freshwater lake and sandy shore habitats. Description The Magellanic oystercatcher has a length between . The male weighs around and the female is a little heavier. This bird has a long, orange beak, yellow eye and eye ring, and yellow legs. The head, breast, back, wings and tail are black and the underparts are white, as are the feathers on the inner part of the wing which can be seen in flight. It is very similar in appearance to the American oystercatcher (''Haematopus palliatus''), but can be distinguished by the yellow ring of bare skin that surrounds its yellow eye and the white secondary feathers. No other species of oystercatcher has these two features, and it is also the only New World species to have a black rather than a brown back. The call is similar to other oystercatchers, a repeated high-pitched " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned specia ...
