Red-necked Stint
The red-necked stint (''Calidris ruficollis'') is a small migratory wader. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''ruficollis'' is from Latin ''rufus'', "red" and ''collum'', "neck". Description These birds are among the smallest of waders, very similar to the little stint, ''Calidris minuta'', with which they were once considered conspecific. The red-necked stint's small size, fine dark bill, dark legs and quicker movements distinguish this species from all waders except the other dark-legged stints. It measures in length, in wingspan and in body mass. It can be distinguished from the western sandpiper and the semipalmated sandpiper in all plumages by its combination of a fine bill tip, unwebbed toes, and longer primary projection. The breeding adult has an unstreaked orange breast, bordered with dark markings below, and a white V on its back. In winter plumage identif ...

Ireland
Ireland (, ; ; Ulster Scots dialect, Ulster-Scots: ) is an island in the North Atlantic Ocean, in Northwestern Europe. Geopolitically, the island is divided between the Republic of Ireland (officially Names of the Irish state, named Irelanda sovereign state covering five-sixths of the island) and Northern Ireland (part of the United Kingdomcovering the remaining sixth). It is separated from Great Britain to its east by the North Channel (Great Britain and Ireland), North Channel, the Irish Sea, and St George's Channel. Ireland is the List of islands of the British Isles, second-largest island of the British Isles, the List of European islands by area, third-largest in Europe, and the List of islands by area, twentieth-largest in the world. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islands by population, ...

Birds Of North Asia
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have ...

Wading Birds
Birders in Canada and the United States refer to several families of long-legged wading birds in semi-aquatic ecosystems as waders. These include the families Phoenicopteridae (flamingos), Ciconiidae (storks), Threskiornithidae (ibises and spoonbills), Ardeidae (herons, egrets, and bitterns), and the extralimital families Scopidae (hamerkop) and Balaenicipitidae (shoebill) of Africa. Elsewhere in the world, the word refers to what North Americans call a "shorebird", various families of the order Charadriiformes. In the past all of these families were classified in the order Ciconiiformes based on overall similarity in anatomy and ecology, as well as some molecular data.

However recent genomic studies have found that this group to be polyphyletic, with flamingos being more closely related to grebes while ib ...

Erolia
''Calidris'' is a genus of Arctic-breeding, strongly migratory wading birds in the family Scolopacidae. These birds form huge mixed flocks on coasts and estuaries in winter. Migratory shorebirds are shown to have decline in reproductive traits because of temporal changes of their breeding seasons. They are the typical " sandpipers", small to medium-sized, long-winged and relatively short-billed. Their bills have sensitive tips which contain numerous corpuscles of Herbst. This enables the birds to locate buried prey items, which they typically seek with restless running and probing. Taxonomy The genus ''Calidris'' was introduced in 1804 by the German naturalist Blasius Merrem with the red knot as the type species. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The genus contain 24 species: * Great knot, ''Calidris tenuirostris'' * Red knot, ''Calidris canutus'' * Surfbird, ''Calidris ...

British Birds (magazine)
''British Birds'' is a monthly ornithology magazine that was established in 1907. It is now published by BB 2000 Ltd, which is wholly owned by The British Birds Charitable Trust (registered charity number 1089422), established for the benefit of British ornithology. Its circulation in 2000 was 5,250 copies; its circulation peaked at 11,000 in the late 1980s. The current editor is Stephen Menzie. ''British Birds'' is aimed at serious birdwatchers and ornithologists, rather than the more casual birdwatchers catered for by some other magazines on the subject. It publishes the findings of the British Birds Rarities Committee. Its mascot, and later logo, the red grouse, was chosen because at the time it was then considered an endemic British species; though subsequently long considered a subspecies of the willow grouse, further study resulted in it being returned to separate species status in 2024. In 1916, ''British Birds'' magazine absorbed ''The Zoologist'', due to the latter's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tundra
In physical geography, a tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: #Arctic, Arctic, Alpine tundra, Alpine, and #Antarctic, Antarctic. Tundra vegetation is composed of dwarf shrubs, Cyperaceae, sedges, Poaceae, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained greenhouse gases into the atmosphere, creating Climate change feedback, a feedback cycle t ...

Curlew Sandpiper
The curlew sandpiper (''Calidris ferruginea'') is a small wader that breeds on the tundra of Arctic Siberia. It is strongly bird migration, migratory, wintering mainly in Africa, but also in south and southeast Asia and in Australia and New Zealand. It is a Vagrancy (biology), vagrant to North America. Taxonomy The curlew sandpiper was species description, formally described in 1763 by the Danish author Erik Pontoppidan under the binomial name ''Tringa ferrugineus''. It 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 ''ferruginea'' is from Latin ''ferrugo, ferruginis'', "iron rust" referring to its colour in breeding plumage. The curlew sandpiper is treated as monotypic: no subspecies are recognised.
