Plovers And Lapwings
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 dott ...

Hooded Dotterel
The hooded dotterel or hooded plover (''Thinornis cucullatus'') is a species of bird in the family Charadriidae. It is endemic to southern Australia, where it inhabits ocean beaches and subcoastal lagoons. There are two recognised subspecies which form isolated eastern and western populations. The eastern subspecies is of greater conservation concern, with listings varying from Vulnerable in South Australia and Victoria to Critically Endangered in New South Wales. Taxonomy The hooded dotterel was placed in genus ''Charadrius'' but in the early 2000s it was reclassified into the genus ''Thinornis'', along with shore plover (''Thinornis novaeseelandiae''). In 2000 the number of mature individuals was estimated at 7,000. Alternative common names include: hooded plover, hoody, ''pluvier à camail'' (in French), ''kappenregenpfeifer'' (in German), and ''chorlito encapuchado'' (in Spanish). Subspecies Two subspecies of the hooded dotterel are now recognised. * ''T. c. cucullatus'' (V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
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 ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 further evolved for swimming. B ...

Wrybill
The wrybill or (in Māori) ngutuparore (''Anarhynchus frontalis'') is a species of plover endemic to New Zealand. It is the only species of bird in the world with a beak that is bent sideways in one direction, always to the right (in the crossbills, e.g. ''Loxia pytyopsittacus'', the tips of the upper and lower mandibles cross because they are bent sideways in opposite directions, sometimes left over right and sometimes right over left). A 2015 study found it to be within the ''Charadrius'' clade, with other New Zealand plovers its closest relatives; the nearest being the New Zealand dotterel or New Zealand plover (''Charadrius obscurus''), and then the double-banded plover or banded dotterel (''Charadrius bicinctus''). It lays its eggs among the rocks along rivers and distracts intruders by pretending to be in distress and moving away from its clutch. It is rated as vulnerable on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species. Taxono ...

Inland Dotterel
The inland dotterel (''Peltohyas australis'') is an endemic bird of the arid Australian interior. It forms loose flocks in sparsely vegetated gibber plain and claypans in the day where it loafs in the shade and eats shoots of shrubs. It is most often encountered at night when it forages on roads for insects. The relative remoteness of its habitat means that it is not well studied. The most detailed observations of the species were made by the South African arid-zone ornithology specialist Gordon Maclean in the 1970s. Alternate English names include Australian plover, inland plover, desert plover and prairie plover. Description The inland dotterel is a medium-sized plover with a distinctive cryptic plumage. Males and females are similarly sized: in length, a wingspan of a weight of , and a short bill . It is unlikely to be confused with any other species when found in its normal habitat. Its upperparts are a rich sandy buff, mottled with dark brown. The black band across the cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-kneed Dotterel
The red-kneed dotterel (''Erythrogonys cinctus'') is a species of plover in a monotypic genus in the subfamily Vanellinae. It is often gregarious and will associate with other waders of its own and different species, even when nesting. It is nomadic and sometimes irruptive. Description Adults distinctively marked: black cap or hood from bill, extending below eyes, merging at nape to grey-brown of back. White chin and throat. Broad black band on breast joining nape and also extending to flanks as chestnut stripe. Belly and vent white. Back and mantle grey-brown, mainly black upperwing with white trailing edge. Upper leg, including tarsal joint or "knee", red. Bill red with dark tip. Distribution The red-kneed dotterel is native to mainland Australia, Papua New Guinea, and Indonesia, and has occurred as a vagrant in Tasmania, Palau and New Zealand. Habitat Mainly margins of shallow ephemeral and permanent freshwater wetlands, occasionally saline wetlands, but rarely t ...

International Ornithological Committee
The International Ornithologists' Union, formerly known as the International Ornithological Committee, is a group of about 200 international ornithologists, and is responsible for the International Ornithological Congress and other international ornithological activities, undertaken by its standing committees. International Ornithological Congress The International Ornithological Congress series forms the oldest and largest international series of meetings of ornithologists. It is organised by the International Ornithologists' Union. The first meeting was in 1884; subsequent meetings were irregular until 1926 since when meetings have been held every four years, except for two missed meetings during and in the immediate aftermath of the Second World War.

Distraction Display
Distraction displays, also known as diversionary displays, or paratrepsis are anti-predator behaviors used to attract the attention of an enemy away from something, typically the nest or young, that is being protected by a parent. Distraction displays are sometimes classified more generically under "nest protection behaviors" along with aggressive displays such as mobbing. These displays have been studied most extensively in bird species, but also have been documented in populations of stickleback fishRuxton, Graeme D; Thomas N. Sherratt; Michael Patrick Speed. (2004) Avoiding attack: the evolutionary ecology of crypsis, warning signals and mimicry. Oxford University Press. . p. 198 and in some mammal species. Distraction displays frequently take the form of injury-feigning. However, animals may also imitate the behavior of a small rodent or alternative prey item for the predator; imitate young or nesting behaviors such as brooding (to cause confusion as to the true location of th ...

Snipe
A snipe is any of about 26 wading bird species in three genera in the family Scolopacidae. They are characterized by a very long, slender bill, eyes placed high on the head, and cryptic/camouflaging plumage. The ''Gallinago'' snipes have a nearly worldwide distribution, the ''Lymnocryptes'' snipe is restricted to Asia and Europe and the ''Coenocorypha'' snipes are found only in the outlying islands of New Zealand. The four species of painted snipe are not closely related to the typical snipes, and are placed in their own family, the Rostratulidae. Behaviour Snipes search for invertebrates in the mud with a "sewing-machine" action of their long bills. The sensitivity of the bill is caused by filaments belonging to the fifth pair of nerves, which run almost to the tip and open immediately under the soft cuticle in a series of cells; a similar adaptation is found in sandpipers; this adaptation give this portion of the surface of the premaxillaries a honeycomb-like appearance: w ...

Polar Regions Of Earth
The polar regions, also called the frigid geographical zone, zones or polar zones, of Earth are the regions of the planet that surround its geographical poles (the North Pole, North and South Poles), lying within the polar circles. These high latitudes are dominated by floating Arctic ice pack, sea ice covering much of the Arctic Ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica and the Southern Ocean in the south. Definitions The Arctic has various definitions, including the region north of the Arctic Circle (currently Epoch 2010 at 66°33'44" N), or just the region north of 60th parallel north, 60° north latitude, or the region from the North Pole north to the Tree line, timberline. The Antarctic is usually defined simply as south of 60th parallel south, 60° south latitude, or the continent of Antarctica. The 1959 Antarctic Treaty System, Antarctic Treaty uses the former definition. The two polar regions are distinguished from the other two c ...

Ibis (journal)
''Ibis'' (formerly ''The Ibis''), subtitled ''the International Journal of Avian Science'', is the peer-reviewed scientific journal of the British Ornithologists' Union. It was established in 1859. Topics covered include ecology, conservation, behaviour, palaeontology, and taxonomy of birds. The editor-in-chief is Dominic J. McCafferty (University of Glasgow). The journal is published by Wiley-Blackwell in print and online. It is available free on the internet for institutions in the developing world through the OARE scheme (Online Access to Research in the Environment). History In 1858 the British Ornithologists' Union (BOU) was formed. It was the first organization, devoted solely to the study of birds. One year later members of the BOU founded a (Quarterly) "Magazine of General Ornithology," entitled ''The Ibis''. Series and editors * Series 1 was published from 1859 to 1864, in six volumes and 24 issues. The first editor was Philip Lutley Sclater (1829–1913).Sep. ixv ...
