Forest Raven
The forest raven (''Corvus tasmanicus''), also commonly known as the Tasmanian raven, is a passerine bird in the family Corvidae native to Tasmania and parts of southern Victoria, such as Wilsons Promontory and Portland. Populations are also found in parts of New South Wales, including Dorrigo and Armidale. Measuring in length, it has all-black plumage, beak and legs. As with the other two species of raven in Australia, its black feathers have grey bases. Adults have white irises; younger birds have dark brown and then hazel irises with an inner blue rim. New South Wales populations are recognised as a separate subspecies ''C. tasmanicus boreus'', but appear to be nested within the Tasmanian subspecies genetically. The forest raven lives in a wide variety of habitats in Tasmania but is restricted to more closed forest on mainland Australia. Breeding takes place in spring and summer, occurring later in Tasmania than in New South Wales. The nest is a bowl-shaped structure of stic ...

Gregory Mathews
Gregory Macalister Mathews Order of the British Empire, CBE FRSE FZS FLS (10 September 1876 – 27 March 1949) was an Australian-born amateur ornithologist who spent most of his later life in England. Life He was born in Biamble, New South Wales, Biamble in New South Wales the son of Robert H. Mathews. He was educated at The King's School, Parramatta. Mathews made his fortune in mining shares, and moved to England in 1902. In 1910 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were William Eagle Clarke, Ramsay Heatley Traquair, John Alexander Harvie-Brown and William Evans (naturalist), William Evans. Ornithology Mathews was a controversial figure in Australian ornithology. He was responsible for bringing trinomial nomenclature into local taxonomy, however he was regarded as an extreme splitter. He recognised large numbers of subspecies on scant evidence and few notes. The extinct Lord Howe Pigeon was described by Mathews in 1915, using a painting as ...

Tuberculosis
Tuberculosis (TB) is an infectious disease usually caused by '' Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with Latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active TB is ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ...

Little Crow (bird)
The little crow (''Corvus bennetti'') is an Australian species of crow, very similar to the Torresian crow in having white bases to the neck and head feathers (shown when ruffled in strong wind) but slightly smaller (38–45 cm in length) and with a slightly smaller bill. It has the same white iris that distinguish the Australian species from all other ''Corvus'' except a few island species to the north of Australia, and one from Eurasia, the jackdaw (''Corvus monedula''). Like the Australian raven, this species has a blue ring around the pupil. Distribution and habitat It ranges over western and central Australia, often inhabiting very dry, near desert areas. It frequents small country towns and cultivated areas, where its flocks have reminded people of the European rook. Etymology ''C. bennetti'' was named in honour of the New South Wales ornithologist and collector of natural history specimens, Kenric Harold Bennett. Behaviour Diet Its food is mainly taken from the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

International Ornithologists' Union
The International Ornithologists' Union, formerly known as the International Ornithological Committee, is a group of about 200 international ornithologists, and is responsible for the International Ornithological Congress and other international ornithological activities, undertaken by its standing committees. International Ornithological Congress The International Ornithological Congress series forms the oldest and largest international series of meetings of ornithologists. It is organised by the International Ornithologists' Union. The first meeting was in 1884; subsequent meetings were irregular until 1926 since when meetings have been held every four years, except for two missed meetings during and in the immediate aftermath of the Second World War.

International Code Of Zoological Nomenclature
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of binominal nomenclature * Which name must be used in case of name conflicts * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia'' in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all animals, except where taxonomic judgment dictates otherwise. The code is meant to guid ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Charles Vaurie
Charles Vaurie (7 July 1906, Beaulieu-sur-Dordogne, France – 13 May 1975, Reading, Pennsylvania) was a French-born American ornithologist. He was born in France, but moved to Trenton, New Jersey as a youth. He studied at New York University and then qualified as a dentist at the University of Pennsylvania in 1928. An interest in painting birds developed, and after marrying his entomologist wife, Patricia Wilson, in 1934, the two shared numerous field trips. Vaurie became associated with the American Museum of Natural History and by 1946 he was a Research Associate. He went on to produce more than 150 ornithological publications. His most important work was a systematic review of Palearctic birds. By 1956, he was a full-time ornithologist at AMNH, and rose to Curator by 1967. At the time of his death he was a member of the Standing Committee on Ornithological Nomenclature of the International Ornithological Congress. He described for the first time the cryptic flycatcher (' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Torresian Crow
The Torresian crow (''Corvus orru''), also called the Australian crow or Papuan crow, is a passerine bird in the crow family native to the north and west of Australia and nearby islands in Indonesia and Papua New Guinea. The species has a black plumage, beak and mouth with white irises. The base of the feathers on the head and neck are white. The Torresian crow is slightly larger with a more robust bill than the morphologically similar little crow. Taxonomy The Torresian crow was described by the French ornithologist Charles Lucien Bonaparte in 1850. The origin of the specific epithet ''orru'' is not known but may be derived from a Papuan name. There are three subspecies: * ''C. o. latirostris'' Meyer, AB, 1884 – east Lesser Sunda Islands * ''C. o. orru'' Bonaparte, 1850 – Maluku Islands, New Guinea, D'Entrecasteaux Islands. and Louisiade Archipelago * ''C. o. cecilae'' Mathews, 1912 – west, central and northern Australia The Bismarck crow (''Corvus insulari ...

Australian Raven
The Australian raven (''Corvus coronoides'') is a passerine bird in the genus ''Corvus'' native to much of southern and northeastern Australia. Measuring in length, it has all-black plumage, beak and mouth, as well as strong grey-black legs and feet. The upperparts are glossy, with a purple, blue, or green sheen, and its black feathers have grey bases. The Australian raven is distinguished from the Australian crow species by its throat hackles, which are prominent in adult birds. Older adult individuals have white irises, younger adults have white irises with an inner blue rim, while younger birds have dark brown irises until fifteen months of age, and hazel irises with an inner blue rim around each pupil until age two years and ten months. Nicholas Aylward Vigors and Thomas Horsfield described the Australian raven in 1827, its species name (''coronoides'') highlighting its similarity with the carrion crow (''C. corone''). Two subspecies are recognized, which differ slightly in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Little Raven
The little raven (''Corvus mellori'') is a species of the family Corvidae that is native to southeastern Australia. An adult individual is about in length, with completely black plumage, beak, and legs; as with all Australian species of ''Corvus'', the black feathers have a grey base, and the iris of the adult bird is white (typical also of some related species from islands to the north of Australia). Although the little raven was first named by Gregory Mathews in 1912, it was only in 1967 that there was consensus to separate it from the Australian raven (''C. coronoides'') as a distinct species. Taxonomy In the 1960s, the CSIRO were intensively studying Australian raven populations and their relationship to lambing and sheep in southeastern Australia. It became evident that there was a smaller species of raven living alongside the Australian raven. These birds lived in smaller trees, had smaller throat hackles and lacked the bare skin of their larger relative. They were also n ...
