Eurasian Teal
The Eurasian teal (''Anas crecca''), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal. It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (''A. carolinensis'') was formerly (and sometimes is still) considered a subspecies of ''A. crecca''. Taxonomy The Eurasian teal belongs to the "true" teals, a group of small '' Anas'' dabbling ducks closely related to the mallard (''A. platyrhynchos'') and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laysan Duck
The Laysan duck (''Anas laysanensis''), also known as the Laysan teal, is a dabbling duck endemic to the Hawaiian Islands. Fossil evidence reveals that Laysan ducks once lived across the entire archipelago, but today survive only on Laysan Island and two atolls. The duck has several physical and behavioral traits linked to the absence of ground-based predators in its habitat. By 1860, the ducks had disappeared from everywhere except Laysan Island. The introduction of European rabbits by guano miners at the end of the 19th century brought the bird to the brink of extinction in 1912, with twelve surviving individuals. Rabbits were eradicated from the island in 1923 and numbers of Laysan ducks began to rise, reaching 500 by the 1950s. In an effort to ensure the long-term future of this duck, 42 birds were translocated to Midway Atoll National Wildlife Refuge in 2002. These thrived in their new surroundings, and another group were later relocated to Kure Atoll. Taxonomy Named b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andean Teal
The Andean teal (''Anas andium'') is a South American species of duck. Like other teals, it belongs to the diverse genus ''Anas''; more precisely it is one of the "true" teals of subgenus ''Nettion''. It is restricted to the Andean highlands of Colombia, Venezuela, and Ecuador. It inhabits freshwater wetlands, preferring palustrine habitat to rivers. It is not considered threatened by the IUCN. Taxonomy Mitochondrial DNA sequence data is most similar to that of the very different-looking green-winged teal. Apart from the mystifying relationship with the red-and-green-headed teals, it altogether most resembles the Indian Ocean radiation of teals. Traditionally, there are 2 subspecies: * Mérida teal, ''Anas andium altipetens'' (Conover, 1941) – highlands of north-west Venezuela and adjacent parts of Colombia. * nominate, ''Anas andium andium'' ( Sclater & Salvin, 1873) - highlands of Colombia and Ecuador. This species and the yellow-billed teal are sometimes considered c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Teal
The silver teal or versicolor teal (''Spatula versicolor'') is a species of dabbling duck in the genus ''Spatula''. It breeds in South America. Between April and June they prefer reed beds and will lay 6 to 10 creamy-pink eggs. As with swans and geese, both parents will rear the ducklings. A pair may bond long term. It lives on fresh water in small groups, and feeds primarily on vegetable matter such as seeds and aquatic plants. The silver teal's range includes southern Bolivia, southern Brazil, Paraguay, Argentina, Chile, Uruguay, South Georgia, South Sandwich Islands, and the Falkland Islands.Clements, J. (2007) The southernmost birds migrate to southern Brazil in the winter. Silver teals are on the whole placid ducks but may be protective of eggs, young and females. Description They have a black cap that extends below the eyes, and a bluish bill with a yellow tip. They also have a green speculum with a white border. The Puna teal was previously regarded as a subspecie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-winged Teal
The blue-winged teal (''Spatula discors'') is a species of bird in the duck, goose, and swan family Anatidae. One of the smaller members of the dabbling duck group, it occurs in North America, where it breeds from southern Alaska to Nova Scotia, and south to northern Texas. It winters along the Pacific and Atlantic coasts and south into the Caribbean islands and Central America. Taxonomy The first formal description of the blue-winged teal was by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae''. He coined the binomial name ''Anas discors''. A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus ''Anas'', as then defined, was non-monophyletic. The genus was subsequently split into four monophyletic genera with ten species including the blue-winged teal moved into the resurrected genus '' Spatula''. This genus had been originally proposed by the German zoologist Friedrich Boie i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chestnut Teal
The chestnut teal (''Anas castanea'') is a dabbling duck found in Australia. It is protected under the National Parks and Wildlife Act 1974. Taxonomy The chestnut teal was described by the English naturalist Thomas Campbell Eyton in 1838 under the binomial name ''Mareca castanea''. The specific epithet ''castanea'' is from the Latin ''castaneus'' for "chestnut-coloured" or "chestnut-brown". A large molecular phylogentic study that compared mitochondrial DNA sequences from ducks, geese and swans in the family Anatidae found that the chestnut teal is a sister species to the Sunda teal (''Anas gibberifrons'') that is endemic to Indonesia. Description The chestnut teal is darker and a slightly bigger bird than the grey teal. The male has a distinctive green coloured head and mottled brown body. The female has a brown head and mottled brown body. The female is almost identical in appearance to the grey teal. The female chestnut teal has a loud penetrating "laughing" quack repea ...

Andaman Teal
The Andaman teal (''Anas albogularis'') is a species of duck endemic to the Andaman archipelago in the Bay of Bengal. The species was formerly considered as a subspecies of the Sunda teal. Taxonomy The first formal description of the Andaman teal was by the English ornithologist Allan Octavian Hume in 1873 under the binomial name ''Mareca albogularis''. It is now placed with many other dabbling ducks in the genus ''Anas''. It was formerly considered as a subspecies of the Sunda teal (''Anas gibberifrons'') that is found in Indonesia. Description The species is dark brown with buffy markings. The face and throat are pale with a white ring around the eye. The bill is bluish grey and the iris is red. Distribution and habitat Andaman teals are endemic to the Andaman Islands The Andaman Islands () are an archipelago in the northeastern Indian Ocean about southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunda Teal
The Sunda teal (''Anas gibberifrons''), also known as the Bebek cokelat or Itik benjut, is a dabbling duck found in open wetlands in Indonesia. The species formerly included the Andaman teal ''Anas albogularis'' and the grey teal, ''Anas gracilis'' as subspecies, but is currently considered monotypic. A molecular phylogentic study published in 2009 that compared mitochondrial DNA sequences from ducks, geese and swans in the family Anatidae found that the Sunda teal is a sister species of the chestnut teal (''Anas castanea'') native to Australia. This is a mottled brown duck with white and green flashes on its wings. The male and female Sunda teal share the same colouration, in contrast to the related chestnut teal, whose male and female are strikingly different. The nominate Sunda teal has almost identical colouration to the female chestnut teal and can only be distinguished by its lighter coloured neck, paler face and especially the bulging forehead. The Andaman teal has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-billed Teal
The yellow-billed teal (''Anas flavirostris'') is a South American species of duck. Like other teals, it belongs to the diverse genus ''Anas''; more precisely it is one of the "true" teals of subgenus ''Nettion''. It occurs in Argentina, the Falkland Islands, Chile, Peru, Bolivia, Uruguay, and Brazil. It has also established itself in South Georgia, where it was first recorded breeding in 1971, and has been recorded as far east as Tristan da Cunha. It inhabits freshwater wetlands, preferring palustrine habitat to rivers. Considering its wide range and local abundance, it is not considered threatened by the IUCN. Description The namesake bill is bright yellow with a black tip and a black band along the ridge of the culmen. The species is somewhat similar to the larger yellow-billed pintail, but has a darker head, shorter neck and plain grayish sides. Taxonomy Mitochondrial DNA sequence data is most similar to that of the very different-looking green-winged teal.Johnson & ...

Cape Teal
The Cape teal (''Anas capensis'') also Cape wigeon or Cape widgeon is a 44–46 cm long dabbling duck of open wetlands in sub-Saharan Africa. Taxonomy The Cape teal was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the ducks, geese and swans in the genus ''Anas'' and coined the binomial name ''Anas capensis''. Gmelin based his description on the "Cape widgeon" that had been described in 1785 by the English ornithologist John Latham in his ''A General Synopsis of Birds''. The naturalist Joseph Banks had provided Latham with a water-colour drawing of the teal by Georg Forster who had accompanied James Cook on his second voyage to the Pacific Ocean. His picture was drawn in 1773 at the Cape of Good Hope. This picture is now the holotype for the species and is held by the Natural History Museum in London. The genus name ''Anas'' is the Latin word for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puna Teal
The Puna teal (''Spatula puna'') is a species of dabbling duck in the family Anatidae. It was at one time regarded as a subspecies of the silver teal. The Puna teal is resident in the Andes of Peru, western Bolivia, northern Chile, and extreme northwestern Argentina.Clements, J. (2007) It is found on the larger lakes and pools in the altiplano. The status of the Puna teal is Least Concern, as listed on the IUCN Red List. Taxonomy The first formal description of the Puna teal was by the Swiss naturalist Johann Jakob von Tschudi in 1844 under the binomial name ''Anas puna''. It was at one time considered as a subspecies of the silver teal in the genus ''Anas''. A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus ''Anas'', as then defined, was non-monophyletic. The genus was subsequently split into four monophyletic genera with ten species including the Puna teal moved into the resurrected genus ''Spatula''. This genus had ...
