Baer's Pochard
Baer's pochard (''Aythya baeri'') is a diving duck found in eastern Asia. It is a bird in North and Central China, and formerly bred in southeast Russia and Northeast China, migrating in winter to southern China, Vietnam, Japan, and India. Baer's pochard is a monotypic species. The holotype was collected in middle Amur. It has a distinctive black head and neck with green gloss. While in poor light, it is likely to look completely black. It is similar and closely related to the ferruginous duck, and they were previously considered to be a single species; Baer's pochard is differentiated by its white flanks when floating on the water, as well as its longer, more rounded head and larger size. Its breeding season varies by latitude and environment. The nest, built from sedges, reeds and other plants, is placed among emergent vegetation, usually in shallow water or on small islands or ridges. Its clutch size ranges from 5 to 14. Males usually take on sentry duty, and females take o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Pochard
The common pochard (; ''Aythya ferina''), known simply as pochard in the United Kingdom, is a medium-sized diving duck in the family Anatidae. It is widespread across the Palearctic. It breeds primarily in the steppe regions of Scandinavia and Siberia, and winters further south and west. Taxonomy and systematics Swedish taxonomist Carl Linnaeus first assigned a scientific name to the common pochard in the tenth edition of his landmark treatise Systema Naturae; this was the first edition which included such names. He called the duck ''Anas ferina''. In 1822, German zoologist Friedrich Boie created the genus '' Aythya'' for various diving ducks, and moved the common pochard to that new genus. Uptake of ''Aythya'' as the genus for the common pochard was mixed for much of the next century, with some authors leaving the duck in the genus ''Anas'' or assigning it to various other now-defunct genera instead. The common pochard is considered a superspecies with the canvasback. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosy-billed Pochard
The rosy-billed pochard (''Netta peposaca''), alternatively named rosybill or rosybill pochard, is a member of family Anatidae. Though classified as a diving duck, this pochard feeds more like a dabbling duck feeding on seeds roots, sedges, aquatic plants and other grasses. ''Netta'' is Ancient Greek for "duck" and ''peposaca'' is a transcription of the Guaraní name of this species which means "showy wings", referring to the broad white stripe that is only visible with stretched out wings. Male characteristic features include a bright red bill with a rounded knob at the base. The rosy-billed pochard is endemic to South America. It is found in Argentina, central Chile, Paraguay, Uruguay and southern Brazil. The population in southern Argentina migrates northward during the austral winter, reaching Brazil and southern Bolivia. It is a vagrant to the Falkland Islands. Taxonomy The rosy-billed pochard is one of five pochard species that make up the genus ''Netta,'' which is one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar Pochard
The Madagascar pochard or Madagascan pochard (''Aythya innotata''; ) is an extremely rare diving duck of the genus ''Aythya''. Thought to be extinct in the late 1990s, specimens of the species were rediscovered at Lake Matsaborimena near Bemanevika in Madagascar in 2006. By 2017, a captive breeding program had produced a population of around 90 individuals. The birds were reintroduced to the wild in December 2018. The Madagascar pochard feeds mainly on aquatic insects, unlike other diving ducks in the same genus, The population is small, fluctuating around 25 individuals, and mainly utilises two small volcanic lakes in the far north of Madagascar. ''Aythya''. Ducklings begin making short dives at around 14 days old, before which they feed on the surface. Taxonomy The Madagascar pochard was largely overlooked by scientists in the 19th century, as those that saw it assumed they were seeing ferruginous ducks instead. Even after its description in 1894 little notice was taken of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aythya
''Aythya'' is a genus of diving ducks, with twelve species currently accepted. The genus was described in 1822 by the German zoologist Friedrich Boie, with the type species being greater scaup. The name ''Aythya'' comes from the Ancient Greek word (), which referred to an unknown diving-bird. The species are plump, compact, medium-sized ducks ranging from 37–61 cm long, 60–84 cm wingspan, and weighing 410–1600 g, with canvasback the largest, and ring-necked duck and ferruginous duck marginally the smallest. The body plumage is variably white, grey, red-brown, or black, often with a finely vermiculated pattern; in several species, the flanks are white or pale grey, the back darker grey to black, and the breast and tail black. The heads are strongly coloured in the males, orange-red in some species, and black with a green to purple sheen ( structural colour) in good light; the sheen colour varies with both species and angle of light incidence – in for exa ...

Netta
''Netta'' is a genus of diving ducks. The name is derived from Greek ''Netta'' "duck". Unlike other diving ducks, the ''Netta'' species are reluctant to dive, and feed more like dabbling ducks. These are gregarious ducks, mainly found on fresh water. They are strong fliers; their broad, blunt-tipped wings require faster wing-beats than those of many ducks and they take off with some difficulty. They do not walk as well on land as the dabbling ducks because their legs tend to be placed further back on their bodies to help propel them when underwater. The probably extinct pink-headed duck The pink-headed duck (''Rhodonessa caryophyllacea'') is a large diving duck that was once found in parts of the Indo-Gangetic Plain, Gangetic plains of India, Nepal, parts of Maharashtra, Bangladesh and in the riverine swamps of Myanmar but has b ..., previously listed as ''Rhodonessa caryophyllacea'', has recently been shown by phylogenetic analysis to be closely related to the red-crested ...

Red-crested Pochard
The red-crested pochard (''Netta rufina'') is a large diving duck. The scientific name is derived from Greek ''Netta'' "duck", and Latin ''rufina'', "golden-red" (from ''rufus'', "ruddy"). Its breeding habitat is lowland marshes and lakes in southern Europe and it extends from the steppe and semi-desert areas on the Black Sea to Central Asia and Mongolia, wintering in the Indian Subcontinent and Africa. It is somewhat migratory, and northern birds winter further south into north Africa. The adult male is unmistakable. It has a rounded orange head, red bill and black breast. The flanks are white, the back brown, and the tail black. The female is mainly a pale brown, with a darker back and crown and a whitish face. Eclipse males are like females but with red bills. They are gregarious birds, forming large flocks in winter, often mixed with other diving ducks, such as common pochards. They feed mainly by diving or dabbling. They eat aquatic plants, and typically upend for food mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferruginous Pochard
The ferruginous duck (''Aythya nyroca''), also known as ferruginous pochard, common white-eye or white-eyed pochard, is a medium-sized diving duck from Eurosiberia. The scientific name is derived from the Ancient Greek word, (), an unknown seabird mentioned by authors including Hesychius and Aristotle, and the Russian word, (), the Russian word for pochard, which occurs in the bird's Russian common name. Description The breeding male is a rich, dark chestnut on the head, breast and flanks with contrasting pure white undertail coverts. In flight the white belly and underwing patch are visible. The females are duller and browner than the males. The male has a yellow eye and the females have a dark eye. Habitat The ferruginous duck prefers quite shallow fresh waterbodies with rich submerged and floating vegetation with dense stands of emergent vegetation on the margins. In some areas it will use saline or brackish pools or wetlands. On passage and wintering will also frequ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
