Netta Barzilai Songs
''Netta'' is a genus of diving ducks. The name is derived from Greek language, 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, previously listed as ''Rhodonessa caryophyllacea'', has recently been shown by phylogenetic analysis to be closely related to the red-crested pochard, so has now been transferred to the same genus, as ''Netta caryophyllacea''. However, this has been questioned due to numerous and pronounced peculiarities of that species. Species There are 3 recognized species. References ...

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 more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Auk (journal)
''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 ...

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 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southern Pochard
The southern pochard (''Netta erythrophthalma'') is a species of duck, and a member of the genus ''Netta''. There are two subspecies, the South American (southern) pochard ''N. e. erythrophthalma'' (Wied-Neuwied, 1833) and the African (southern) pochard ''N. e. brunnea'' ( Eyton, 1838). The South American pochard has a fragmented range and is found from Colombia, Venezuela, Brazil, Ecuador, Peru, Bolivia and Argentina to Chile. Here it occurs in a wide variety of shallow fresh waters with submerged vegetation, from the lowlands up to 3,700 metres. The African pochard occurs from the Cape to the Ethiopian highlands on water bodies with or without emergent vegetation. They are suspected to have been strong migrants in the past but the construction of numerous farm dams seems to allow them a more sedentary lifestyle. They reach highest concentrations in Africa's central plateaus and in the south-western winter rainfall region. Taxonomy Two syntype specimens of ''Nyroca brunnea'' Ey ...

Pink-headed Duck
The pink-headed duck (''Rhodonessa caryophyllacea'') is a large diving duck that was once found in parts of the Gangetic plains of India, parts of Maharashtra, Bangladesh and in the riverine swamps of Myanmar but feared extinct since the 1950s. Numerous searches have failed to provide any proof of continued existence. It has been suggested that it may exist in the inaccessible swamp regions of northern Myanmar and some sight reports from that region have led to its status being declared as "Critically Endangered" rather than extinct. The genus placement has been disputed and while some have suggested that it is close to the red-crested pochard ('' Netta rufina''), others have placed it in a separate genus of its own. It is unique in the pink colouration of the head combined with a dark body. A prominent wing patch and the long slender neck are features shared with the common Indian spot-billed duck. The eggs have also been held as particularly peculiar in being nearly spherical. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Jakob Kaup
Johann Jakob von Kaup (10 April 1803 – 4 July 1873) was a German naturalist. A proponent of natural philosophy, he believed in an innate mathematical order in nature and he attempted biological classifications based on the Quinarian system. Kaup is also known for having coined popular prehistoric taxa like '' Pterosauria'' and ''Machairodus''. Biography He was born at Darmstadt. After studying at Göttingen and Heidelberg he spent two years at Leiden, where his attention was specially devoted to the amphibians and fishes. He then returned to Darmstadt as an assistant in the grand ducal museum, of which in 1840 he became inspector. In 1829 he published ''Skizze zur Entwickelungsgeschichte der europäischen Thierwelt'', in which he regarded the animal world as developed from lower to higher forms, from the amphibians through the birds to the beasts of prey; but subsequently he repudiated this work as a youthful indiscretion, and on the publication of Darwin's ''Origin of Species' ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
