Swan
Swans are birds of the family (biology), family Anatidae within the genus ''Cygnus''. The swans' closest relatives include the goose, geese and ducks. Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe (biology), tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae. There are six living and many extinct species of swan; in addition, there is a species known as the coscoroba swan which is no longer considered one of the true swans. Swans usually mate for life, although "divorce" sometimes occurs, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another. The number of bird egg, eggs in each :wikt:clutch, clutch ranges from three to eight. Etymology and terminology The English word ''swan'', akin to the German language, German , Dutch language, Dutch and Swedish language, Swedish , is derived from Indo-European root ' ('to sound, to sing'). Young swans are kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Shelduck
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 ...

Ruddy Shelduck
The ruddy shelduck (''Tadorna ferruginea''), known in India as the Brahminy duck, is a member of the family Anatidae. It is a distinctive waterfowl, in length with a wingspan of . It has orange-brown body plumage with a paler head, while the tail and the flight feathers in the wings are black, contrasting with the white wing-coverts. It is a migratory bird, wintering in the Indian subcontinent and breeding in southeastern Europe and central Asia, though there are small resident populations in North Africa. It has a loud honking call. The ruddy shelduck mostly inhabits inland water-bodies such as lakes, reservoirs and rivers. The male and female form a lasting pair bond and the nest may be well away from water, in a crevice or hole in a cliff, tree or similar site. A clutch of about eight eggs is laid and is incubated solely by the female for about four weeks. The young are cared for by both parents and fledge about eight weeks after hatching. In central and eastern Asia, pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptian Goose
The Egyptian goose (''Alopochen aegyptiaca'') is a member of the duck, goose, and swan family Anatidae. It is native to Africa south of the Sahara and the Nile Valley. Egyptian geese were considered sacred by the Ancient Egyptians, and appeared in much of their artwork. Because of their popularity chiefly as an ornamental bird, escapees are common and feral populations have become established in Western Europe, the United States, and New Zealand. Taxonomy The Egyptian goose is believed to be most closely related to the shelducks (genus ''Tadorna'') and their relatives, and is placed with them in the subfamily Tadorninae. It is the only extant member of the genus ''Alopochen'', which also contains closely related prehistoric and recently extinct species. mtDNA cytochrome ''b'' sequence data suggest that the relationships of ''Alopochen'' to ''Tadorna'' need further investigation. Etymology The generic name ''Alopochen'' (literally, ''fox-goose'') is based on Greek (''alōpós ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Barnacle Goose
The barnacle goose (''Branta leucopsis'') is a species of goose that belongs to the genus '' Branta'' of black geese, which contains species with largely black plumage, distinguishing them from the grey ''Anser'' species. Despite its superficial similarity to the brant goose, genetic analysis has shown it is an eastern derivative of the cackling goose lineage. Taxonomy and naming The barnacle goose was first classified taxonomically by Johann Matthäus Bechstein in 1803. ''Branta'' is a Latinised form of Old Norse ''Brandgás'', "burnt (black) goose" and the specific epithet is from the Ancient Greek ''leukos'' "white", and ''opsis'' "faced". The barnacle goose and the similar brant goose were previously considered one species, and were formerly believed to spawn from the goose barnacle. This gave rise to the English name of the barnacle goose and the scientific name of the brant. It is sometimes claimed that the word comes from a Celtic word for "limpet", but the sense-histor ...

Brant (goose)
The brant or brent goose (''Branta bernicla'') is a small goose of the genus ''Branta''. There are three subspecies, all of which winter along temperate-zone sea-coasts and breed on the high-Arctic tundra. The Brent oilfield was named after the species. Description The brant is a small goose with a short, stubby bill. It measures long, across the wings and weighs . The under-tail is pure white, and the tail black and very short (the shortest of any goose). The species is divided into three subspecies: * Dark-bellied brant goose ''B. b. bernicla'' (Linnaeus, 1758) * Pale-bellied brant goose ''B. b. hrota'' ( Müller, 1776) (also known as light-bellied brent goose in Europe, and Atlantic brant in North America) * Black brant goose ''B. b. nigricans'' (Lawrence, 1846) (sometimes also known as the Pacific brant in North America) Some DNA evidence suggests that these forms are genetically distinct; while a split into three separate species has been proposed, it is not wide ...

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. 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 havin ...
