Widgeon Creek
The wigeons or widgeons are a group of birds, dabbling ducks currently classified in the genus ''Mareca'' along with two other species. There are three extant species of wigeon, in addition to one recently extinct species. Biology There are three extant species: the Eurasian wigeon (''Mareca penelope''), the American wigeon (''M. americana'') and the Chiloé wigeon (''M. sibilatrix''). A fourth species, the Amsterdam wigeon (''Mareca marecula''), became extinct in the 19th century. The wigeons' closest relatives, forming with them the genus ''Mareca'', are the gadwall and the falcated duck. All three wigeons are similarly shaped, with a steep forehead and bulbous rear to the head. Males have a distinctive breeding plumage, in their eclipse plumage Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. ...

Eurasian Wigeon
The Eurasian wigeon or European wigeon (''Mareca penelope''), also known as the widgeon or the wigeon, is one of three species of wigeon in the dabbling duck genus ''Mareca''. It is common and widespread within its Palearctic range. Taxonomy The Eurasian wigeon was described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' under the binomial name ''Anas penelope''. ''Anas'' is the Latin word for "duck", and ''penelope'' refers to a duck that was supposed to have rescued Penelope when she was thrown into the sea. Her name derives from Ancient Greek πήνη ''pene'', "braid" and ὤψ ''ops'' "appearance", from the ruse she used to deter suitors while her husband Ulysses was absent. Description This dabbling duck is long with a wingspan, and a weight of . The breeding male has grey flanks and back, with a black rear end, a dark green speculum and a brilliant white patch on upper wings, obvious in flight or at rest. It has a pink breast, white belly, ...

Falcated Duck
The falcated duck or falcated teal (''Mareca falcata'') is a gadwall-sized dabbling duck from the east Palearctic (East Siberia and Mongolia to North Japan; wintering to India). Taxonomy The closest relative of this species is the gadwall, followed by the wigeons. The species was assigned to the proposed genus ''Mareca'' after its previous placement in the genus ''Anas'' was found to be paraphyletic in 2009. There are many species that have mitochondrial DNA lineages that are phylogenetically intermixed with other species, but studies have rarely tested the cause of such paraphyly. In a study that was conducted, there were tested two hypotheses that could explain mitochondrial paraphyly of Holarctic gadwalls (''Anas strepera'') with respect to Asian falcated ducks (''A. falcata''). First, hybridization could have resulted in falcated duck mitochondrial DNA (mtDNA) introgressing into the gadwall gene pool. Second, gadwalls and falcated ducks could have diverged so recently that mt ...

Ducks
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ...

The Auk
''Ornithology'', formerly ''The Auk'' and ''The Auk: Ornithological Advances'', is a peer-reviewed scientific journal and the official publication of the American Ornithological Society (AOS). It was established in 1884 and is published quarterly. The journal covers the anatomy, behavior, and distribution of birds. It was named for the great auk, the symbol of the AOS. In 2018, the American Ornithology Society announced a partnership with Oxford University Press to publish ''The Auk: Ornithological Advances'' and '' The Condor: Ornithological Applications'' ''.'' In January 2021, the journal was renamed ''Ornithology'', with the stated goal of improving descriptiveness, thematic focus, and ease of citation of the journal title. The society's sister publication '' The Condor'' was renamed ''Ornithological Applications'' at the same time. Editors The following have been editors-in-chief of the journal: See also * List of ornithology journals References External links ...

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 thought to be an endemic British species (although it is now considered a subspecies of the willow grouse). In 1916, ''British Birds'' magazine absorbed ''The Zoologist'', due to the latter's shortage of subscribers. Editors The current editor of ''British Birds'' is Stephen ...

Birding World
''Birding World'' was a monthly birding magazine published in the United Kingdom. It was the magazine of the Bird Information Service, based at Cley next the Sea, Norfolk. With the publication of issue No. 26/12 in January 2014, ''Birding World'' magazine ceased publication. History and profile Originally published in 1987 as ''Twitching'' volume 1, the magazine underwent a name-change to this name, in 1988 (also resetting its volume count back to 1). The editor was Steve Gantlett, and the assistant editor Richard Millington. It was aimed at birders with an interest in the occurrence and identification of rare birds in the United Kingdom and the Western Palearctic. It also covered birding-related material from around the globe.

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Gadwall
The gadwall (''Mareca strepera'') is a common and widespread dabbling duck in the family Anatidae. Taxonomy The gadwall was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. DNA studies have shown that it is a sister species with the falcated duck; the two are closely related to the three species of wigeons, and all of them have been assigned to the genus ''Mareca''. There are two subspecies: * ''M. s. strepera'', the common gadwall, described by Linnaeus, is the nominate subspecies. * ''M. s. couesi'', Coues's gadwall, extinct 1874, was formerly found only on Teraina, a coral atoll in the Pacific Ocean. The specific name ''strepera'' is Late Latin for "noisy". The etymology of the word ''gadwall'' is not known, but the name has been in use since 1666. Description The gadwall is long with a wingspan. The male is slightly larger than the female, weighing on average against her . The breeding male is patterned grey, with a black re ...

American Wigeon
The American wigeon (''Mareca americana''), also known as the baldpate, is a species of dabbling duck found in North America. Formerly assigned to ''Anas'', this species is classified with the other wigeons in the dabbling duck genus ''Mareca''. It is the New World counterpart of the Eurasian wigeon. Taxonomy The American wigeon was formally described in 1789 by German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the other ducks, geese and swans in the genus ''Anas'' and coined the binomial name ''Anas americana''. Gmelin based his description on Edme-Louis Daubenton's hand-colour plate of "Le Canard Jensen, de la Louisiane" and Thomas Pennant's description of the "American wigeon" in his ''Arctic Zoology''. Pennant had been sent a specimen from New York. The American wigeon is now placed with the Eurasian wigeon and three other dabbling ducks in the genus ''Mareca'' that was introduced in 182 ...

Amsterdam Wigeon
The Amsterdam wigeon (''Mareca marecula'', formerly ''Anas marecula''), also known as the Amsterdam Island duck or Amsterdam duck, was a species of anatid waterfowl, endemic to Île Amsterdam (Amsterdam Island), the French Southern Territories. The flightless species is only known from bones and was presumably driven extinct by visiting sealers and the rats they introduced. A 1696 sighting by William de Vlaming of "four-footed animals" in the reeds of Amsterdam Island may have been of this duck, as there are no native land mammals on the island. No naturalist visited Amsterdam Island until 1874, by which time it was infested with rats from visiting ships, and the duck was extinct. The first bones of this species to be discovered, in 1955–56, were thought to most closely resemble those of a garganey. In 1987 bones of at least 33 individuals were recovered from rock cavities, revealing a very small duck with a short pointed bill like a wigeon's. Strong legs and reduced breastbon ...
