Brolga2
The brolga (''Antigone rubicunda''), formerly known as the native companion, is a bird in the crane (bird), crane family. It has also been given the name Australian crane, a term coined in 1865 by well-known ornithology, ornithologist John Gould in his ''The Birds of Australia (Gould), Birds of Australia''. The brolga is a common, gregarious wetland bird species of tropical and south-eastern Australia and New Guinea. It is a tall, upright bird with a small head, long beak, slender neck, and long legs. Its plumage is mainly grey, with black wing tips, and it has an orange-red band on its head. The brolga's courting dance is similar to that of other cranes. The nest is built of wetland vegetation, either on an elevated piece of land or floating on shallow water in marshland, and usually two eggs are laid. Incubation takes 32 days, and the newly hatched young are precocial. The adult diet is omnivorous and includes plant matter, invertebrates, and small vertebrates. Although the bi ...

Rail (bird)
The rails, or Rallidae, are a large cosmopolitan family of small- to medium-sized, ground-living birds. The family exhibits considerable diversity and includes the crakes, coots, and gallinules. Many species are associated with wetlands, although the family is found in every terrestrial habitat except dry deserts, polar regions, and alpine areas above the snow line. Members of the Rallidae occur on every continent except Antarctica. Numerous island species are known. The most common rail habitats are marshland and dense forest. They are especially fond of dense vegetation.Horsfall & Robinson (2003): pp. 206–207 Name "Rail" is the anglicized respelling of the French ''râle'', from Old French ''rasle''. It is named from its harsh cry, in Vulgar Latin *''rascula'', from Latin ''rādere'' ("to scrape"). Morphology The rails are a family of small to medium-sized, ground-living birds. They vary in length from and in weight from . Some species have long necks and in many ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Grus (genus)
''Grus'' is a genus of large birds in the crane family. The genus ''Grus'' was erected by the French zoologist Mathurin Jacques Brisson in 1760. The name ''Grus'' is the Latin word for "crane". The German ornithologist Peter Simon Pallas was sometimes credited with erecting the genus in 1766 but the International Commission on Zoological Nomenclature ruled in 1956 that Brisson should have priority. The genus formerly included additional species. A molecular phylogenetic study published in 2010 found that the genus ''Grus'', as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera, the sandhill crane, the white-naped crane, the sarus crane and the brolga were moved to the resurrected genus ''Antigone'' that had been erected by the German naturalist Ludwig Reichenbach in 1853. The Siberian crane was moved to the resurrected monotypic genus ''Leucogeranus''. Species The genus contains eight species: The HBW/BirdLife and Clements ch ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

White-naped Crane
The white-naped crane (''Antigone vipio'') is a bird of the crane family. It is a large bird, long, about tall, and weighing about , with pinkish legs, a grey-and-white-striped neck, and a red face patch. Distribution The white-naped crane breeds in northeastern Mongolia, northeastern China, and adjacent areas of southeastern Russia, where a program at Khingan Nature Reserve raises eggs provided from U.S. zoos to bolster the species. Different groups of the birds migrate to winter near the Yangtze River, the Korean Demilitarized Zone, and on Kyūshū in Japan. They are the only cranes found in South Korea. They also reach Kazakhstan and Taiwan. Only about 4,900 to 5,400 individuals remain in the wild. Its diet consists mainly of insects, seeds, roots, plants, and small animals. Due to ongoing habitat loss and overhunting in some areas, the white-naped crane is evaluated as vulnerable on the IUCN Red List of Threatened Species. It is listed on Appendix I and II of CITES.

Gamilaraay Language
The Gamilaraay or Kamilaroi language is a Pama–Nyungan languages, Pama–Nyungan language of the Wiradhuric languages, Wiradhuric subgroup found mostly in south-eastern Australia. It is the traditional language of the Gamilaraay, Gamilaraay (Kamilaroi), an Aboriginal Australian people. It has been noted as endangered, but the number of speakers grew from 87 in the 2011 Australian Census to 105 in the 2016 Australian Census. Thousands of Australians identify as Gamilaraay, and the language is taught in some schools. Wirray Wirray, Guyinbaraay, Yuwaalayaay, Waalaraay and Gawambaraay are dialects; Yuwaalaraay/Euahlayi is a closely related language. Name The name Gamilaraay means '-having', with being the word for 'no'. Other dialects and languages are similarly named after their respective words for 'no'. (Compare the division between ''langues d'oïl'' and ''langues d'oc'' in France, distinguished by their respective words for 'yes'.) Spellings of the name, pronounced in the ...

Royal Australasian Ornithologists Union
The Royal Australasian Ornithologists Union (RAOU), now part of BirdLife Australia, was Australia's largest non-government, non-profit, bird conservation organisation. It was founded in 1901 to promote the study and bird conservation, conservation of the native bird species of Australia and adjacent regions, making it Australia's oldest national birding association. In 1996, the organisation adopted the trading name of Birds Australia for most public purposes, while retaining its original name for legal purposes and as the publisher of its journal, the ''Emu (journal), Emu''. In 2012, the RAOU merged with Bird Observation & Conservation Australia to form BirdLife Australia. The RAOU was the instigator of the Atlas of Australian Birds project. It also published (in association with Oxford University Press) the encyclopaedic ''Handbook of Australian, New Zealand and Antarctic Birds''. Its quarterly colour membership magazine was ''Wingspan (magazine), Wingspan''. The RAOU is the Au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
