Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The moose (''Alces alces'') is an extant species, and the dodo (''Raphus cucullatus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species ("Lazarus species"), or if previously-known extant species are reclassified as members of the taxon. Most biologists, zoologists, and botanists are in practice neontologists, and the term neontologist is used large ...

Common Shelduck (Tadorna Tadorna) At Sylvan Heights
The common shelduck (''Tadorna tadorna'') is a waterfowl species of the shelduck genus, ''Tadorna''. It is widespread and common in the Euro-Siberian region of the Palearctic, mainly breeding in temperate and wintering in subtropical regions; in winter, it can also be found in the Maghreb. Fossil bones from Dorkovo (Bulgaria) described as ''Balcanas pliocaenica'' may actually belong to this species. More likely, they are an extinct species of ''Tadorna'' (if not a distinct genus) due to their Early Pliocene age; the present species is not unequivocally attested from the fossil record until some 2–3 million years later (Late Pliocene/ Early Pleistocene). Taxonomy The common shelduck was formally named by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae'' under the binomial name ''Anas tadorna''. Linnaeus largely based his description on "The Sheldrake or Burrough-Duck" that had been described and illustrated in 1731 by the English ...

Whooper Swan
The whooper swan ( /ˈhuːpə(ɹ) swɒn/) (''Cygnus cygnus''), also known as the common swan, pronounced ''hooper swan'', is a large northern hemisphere swan. It is the Eurasian counterpart of the North American trumpeter swan, and the type species for the genus '' Cygnus''. Taxonomy Francis Willughby and John Ray's ''Ornithology'' of 1676 referred to this swan as "the Elk, Hooper, or wild Swan". It was one of the many bird species originally described by Carl Linnaeus in the 1758 10th edition of his ''Systema Naturae'', where it was given the binomial name of ''Anas cygnus''. The species name is from ''cygnus'', the Latin for "swan". Description The whooper swan is similar in appearance to Bewick's swan. It is larger, however, at a length of and a wingspan of . The weight is typically in the range of , with an average of for males and for females. The verified record mass was for a wintering male from Denmark. It is considered to be amongst the heaviest flying birds. Amon ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tundra Swan
The tundra swan (''Cygnus columbianus'') is a small swan of the Holarctic. The two taxa within it are usually regarded as conspecific, but are also sometimes split into two species: Bewick's swan (''Cygnus bewickii'') of the Palaearctic and the whistling swan (''C. columbianus'') proper of the Nearctic. Birds from eastern Russia (roughly east of the Taymyr Peninsula) are sometimes separated as the subspecies ''C. c. jankowskii'', but this is not widely accepted as distinct, with most authors including them in ''C. c. bewickii''. Tundra swans are sometimes separated in the subgenus ''Olor'' together with the other Arctic swan species. Bewick's swan was named in 1830 by William Yarrell after the engraver Thomas Bewick, who specialised in illustrations of birds and animals. ''Cygnus'' is the Latin for "swan", and '' columbianus'' comes from the Columbia River, the type locality. Description ''C. columbianus'' is the smallest of the Holarctic swans, at in length, in wingspan and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mute Swan
The mute swan (''Cygnus olor'') is a species of swan and a member of the waterfowl family Anatidae. It is native to much of Eurosiberia, and (as a rare winter visitor) the far north of Africa. It is an introduced species in North America, home to the largest populations outside of its native range, with additional smaller introductions in Australasia and southern Africa. The name 'mute' derives from it being less vocal than other swan species. Measuring in length, this large swan is wholly white in plumage with an orange beak bordered with black. It is recognizable by its pronounced knob atop the beak, which is larger in males. Taxonomy The mute swan was first formally described by the German naturalist Johann Friedrich Gmelin as ''Anas olor'' in 1789, and was transferred by Johann Matthäus Bechstein to the new genus ''Cygnus'' in 1803. Both ''cygnus'' and ''olor'' mean "swan" in Latin; ''cygnus'' is a variant form of ''cycnus'', a borrowing from Greek ''kyknos'', a word o ...

Lesser White-fronted Goose
The lesser white-fronted goose (''Anser erythropus'') is a goose closely related to the larger white-fronted goose (''A. albifrons''). It breeds in the northernmost Palearctic, but it is a scarce breeder in Europe. There is a re-introduction scheme in Fennoscandia. The scientific name comes from ''anser'', the Latin for "goose", and ''erythropus'', "red-footed", derived from the old Greek ''eruthros'' "red" and ''pous'' "foot". The lesser white-fronted goose winters further south in Europe and is a rare winter vagrant to Great Britain and India. Individual birds formerly appeared regularly at WWT Slimbridge in Gloucestershire, England, where they inspired Sir Peter Scott to set up The Wildfowl and Wetlands Trust—modern records, however, are far less frequent, a consequence of the species' decline on its European breeding grounds. An attractive species, it is also widely kept in wildfowl collections and, as a result, escapes do occur; individuals seen in summer, or in the company ...

Greater White-fronted Goose
The greater white-fronted goose (''Anser albifrons'') is a species of goose related to the smaller lesser white-fronted goose (''A. erythropus''). It is named for the patch of white feathers bordering the base of its bill, in fact ''albifrons ''comes from the Latin ''albus'' "white" and ''frons "''forehead". In Europe it has been known as the white-fronted goose; in North America it is known as the greater white-fronted goose (or "greater whitefront"), and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America. Description Greater white-fronted geese are in length, have a wingspan, and weigh . They have bright orange legs and mouse-coloured upper wing-coverts. They are smaller than greylag geese. As well as being larger than the lesser white-fronted goose, the greater white-fronted goose lacks the yellow eye-r ...

Tundra Bean Goose
The tundra bean goose (''Anser serrirostris'') is a goose that breeds in northern Siberia. This and the taiga bean goose are recognised as separate species by the American Ornithological Society and International Ornithologists' Union, but are considered a single species by other authorities (collectively called bean goose). It is migratory and winters further south in Asia. The taiga and tundra bean goose diverged about 2.5 million years ago and established secondary contact ca. 60,000 years ago, resulting in extensive gene flow. Description The length ranges from , wingspan from and weight from . In the nominate subspecies, males average and females average . The bill is black at the base and tip, with an orange band across the middle; the legs and feet are also bright orange. The upper wing-coverts are dark brown, as in the white-fronted goose (''Anser albifrons'') and the lesser white-fronted goose (''A. erythropus''), but differing from these in having narrow white frin ...

Taiga Bean Goose
The taiga bean goose (''Anser fabalis'') is a goose that breeds in northern Europe and Asia. This and the tundra bean goose are recognised as separate species by the American Ornithological Society and the International Ornithologists' Union, but are considered a single species by other authorities (collectively called bean goose). It is migratory and winters further south in Europe and Asia. The taiga and tundra bean goose diverged about 2.5 million years ago and established secondary contact ca. 60,000 years ago, resulting in extensive gene flow. Description The length ranges from , wingspan from and weight from . In the nominate subspecies, males average and females average . The bill is black at the base and tip, with an orange band across the middle; the legs and feet are also bright orange.

Greylag Goose
The greylag goose or graylag goose (''Anser anser'') is a species of large goose in the waterfowl family Anatidae and the type species of the genus ''Anser''. It has mottled and barred grey and white plumage and an orange beak and pink legs. A large bird, it measures between in length, with an average weight of . Its distribution is widespread, with birds from the north of its range in Europe and Asia migrating southwards to spend the winter in warmer places. It is the type species of the genus ''Anser'' and is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BC. The genus name is from ''anser'', the Latin for "goose". Greylag geese travel to their northerly breeding grounds in spring, nesting on moorlands, in marshes, around lakes and on coastal islands. They normally mate for life and nest on the ground among vegetation. A clutch of three to five eggs is laid; the female incubates the eggs and both parents defend and rear ...

Bar-headed Goose
The bar-headed goose (''Anser indicus'') is a goose that breeds in Central Asia in colonies of thousands near mountain lakes and winters in South Asia, as far south as peninsular India. It lays three to eight eggs at a time in a ground nest. It is known for the extreme altitudes it reaches when migrating across the Himalayas. Taxonomy The grey goose genus ''Anser'' has no other member indigenous to the Indian region, nor any at all to the Ethiopian, Australian, or Neotropical regions. Ludwig Reichenbach placed the bar-headed goose in the monotypic genus ''Eulabeia'' in 1852, though John Boyd's taxonomy treats both ''Eulabeia'' and the genus ''Chen'' as subgenera of ''Anser''. Description The bird is pale grey and is easily distinguished from any of the other grey geese of the genus ''Anser'' by the black bars on its head. It is also much paler than the other geese in this genus. In flight, its call is a typical goose honking. A mid-sized goose, it measures in total length and w ...

Red-breasted Goose
The red-breasted goose (''Branta ruficollis'') is a brightly marked species of goose in the genus ''Branta'' from Eurasia. It is currently classified as vulnerable by the IUCN. Taxonomy and etymology The red-breasted goose is sometimes placed in its own genus ''Rufibrenta'' but appears close enough to the brant goose (''Branta bernicla'') to make this unnecessary, despite its distinct appearance. Today all major authorities include the red-breasted goose in ''Branta''. Genetic studies indicate that the red-breasted goose may be one the few known examples of hybrid speciation in birds, being the result of ancient interbreeding between the ancestral brant goose and white-cheeked goose (the latter being the ancestral species that later split into all today's ''Branta'' species, except the brant and red-breasted geese). This interbreeding appears to have happened at least 3.5 million years ago, with the lineage of the red-breasted goose following its own evolutionary path since th ...
