Eurasian Oystercatchers
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 meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plover
Plovers ( , ) are a widely distributed group of wading birds belonging to the subfamily Charadriinae. Description There are about 66 species in the subfamily, most of them called "plover" or "dotterel". The closely related lapwing subfamily, Vanellinae, comprises about 20 species. Plovers are found throughout the world, with the exception of the Sahara and the polar regions, and are characterised by relatively short bills. They hunt by sight, rather than by feel as longer-billed waders like snipes do. They feed mainly on insects, worms or other invertebrates, depending on the habitat, which are obtained by a run-and-pause technique, rather than the steady probing of some other wader groups. Plovers engage in false brooding, a type of distraction display. Examples include pretending to change position or to sit on an imaginary nest site. Species list in taxonomic sequence The International Ornithological Committee (IOC) recognizes these 45 species of plovers and dotter ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened bills o ...

Robert Swinhoe
Robert Swinhoe FRS (1 September 1836 – 28 October 1877) was an English diplomat and naturalist who worked as a Consul in Formosa. He catalogued many Southeast Asian birds, and several, such as Swinhoe's pheasant, are named after him. Biography Swinhoe was born in Calcutta where his father, who came from a Northumberland family, was a lawyer. There is no clear record of the date of his arrival in England, but it is known he attended the University of London, and in 1854 joined the China consular corps. He was stationed to the remote port of Amoy, some 300 miles to the northeast of Hong Kong, in 1855. While at this port he not only mastered the Chinese language (both official Mandarin and the local Amoy dialect), but also initiated a detailed and authoritative understanding of the ornithology of eastern China. In March, 1856, Swinhoe made an "adventurous" visit to the camphor districts of northwestern Formosa on board a lorcha, a hybrid vessel utilizing a European hull an ...

Georgi Petrovich Dementiev
Georgi Petrovich Dementiev (russian: Гео́ргий Петро́вич Деме́нтьев; 5 July, 1898 – 14 April, 1969) was a Soviet and Russian ornithologist and professor at the University of Moscow. His studies based on museum collections and collaboration with others, notably N. A. Gladkov, resulted in a major six-volume work on the birds of the Soviet Union which was published between 1951 and 1954. Dementiev was born in Petergof, where his father was a physician. He studied at the local gymnasium and joined the University of St Petersburg. Although interested in birds from a young age, his parents wished that he studied law. In 1920 he moved to Moscow to work as a lawyer. Although he had no formal qualifications in biology, he was well read and was fluent in French, German, Polish, Italian and Swedish. He began his research under Mikhail Menzbier Mikhail Aleksandrovich Menzbier (Russian: Михаил Александрович Мензбир; 23 October 1855 – 10 O ...

Sergei Buturlin
Sergei Aleksandrovich Buturlin (russian: Серге́й Александрович Бутурлин); 22 September 1872 in Montreux – 22 January 1938 in Moscow was a Russian ornithologist. A scion of one of the oldest families of Russian nobility, Buturlin spent most his life in Russia. His father A.S Buturlin (1845-1916) was physician, writer and Marxist friend of Leo Tolstoy. He went to school in Simbirsk (modern Ulyanovsk) and studied jurisprudence in St. Petersburg around 1894–95. He then worked in the legal service but his interest in zoology was so strong that he spent most of his career collecting specimens across Russia and Siberia and describing the results of his observations. Until 1892 he collected in the Volga region, then in the Baltic region; from 1900 to 1902 on the islands of Kolguyev and Novaya Zemlya. Between 1904 and 1906 he took part in an expedition to the Kolyma River in Siberia, and in 1909 he visited the Altay Mountains, and he made his final expediti ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Yarrell
William Yarrell (3 June 1784 – 1 September 1856) was an English zoologist, prolific writer, bookseller and naturalist admired by his contemporaries for his precise scientific work. Yarrell is best known as the author of ''The History of British Fishes'' (2 vols., 1836) and ''A History of British Birds'' featuring 564 original engravings (in 3 vols., first ed. 1843, second ed. 1845, third ed. 1856). The latter went into several editions and was the standard reference work for a generation of British ornithologists. He described Bewick's swan in 1830, distinguishing it from the larger whooper swan. Early life Yarrell was born in Duke Street, St James's in London, to Francis Yarrell and his wife Sarah (née Blane). His father and uncle ran a newspaper agency and bookshop. He studied at Dr Nicholson's school in Ealing. His father died in 1794 and the Yarrells moved the short distance to Great Ryder Street, where William lived the rest of his life. In 1802 he became a clerk with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oyster
Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters are in the superfamily Ostreoidea. Some types of oysters are commonly consumed (cooked or raw), and in some locales are regarded as a delicacy. Some types of pearl oysters are harvested for the pearl produced within the mantle. Windowpane oysters are harvested for their translucent shells, which are used to make various kinds of decorative objects. Etymology The word ''oyster'' comes from Old French , and first appeared in English during the 14th century. The French derived from the Latin , the feminine form of , which is the latinisation of the Ancient Greek () 'oyster'. Compare () 'bone'. Types True oysters True oysters are members of the family Ostreidae. This family includes the edible oysters, which mainly belong t ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
