White-bellied Whipbird
The white-bellied whipbird (''Psophodes leucogaster''), also called the Mallee whipbird, is a species of bird in the family Psophodidae. It is endemic to southern Australia. Taxonomy The species was formerly considered as a subspecies of ''Psophodes nigrogularis'', so shared the common name of "western whipbird". The ''Clements Checklist'' refers to this species with the common name western whipbird (white-bellied) to distinguish it from ''P. nigrogularis'' (black-throated). The white-bellied whipbird was described by the Australian ornithologists Frank Howe and John Ross in 1933. It was split from the black-throated whipbird (formerly the western whipbird) based on a comparison of mitochondrial DNA sequences published in 2017. Two subspecies are recognised: * ''P. l. leucogaster'' Howe & Ross, JA, 1933 – south central Australia * ''P. l. lashmari'' Mason, IJ & Schodde, 1991 – Kangaroo Island (off Southern Australia) References {{Taxonbar, from=Q21325131 white-bellied ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psophodidae
Psophodidae is a family of passerine birds native to Australia and nearby areas. It has a complicated taxonomic history and different authors vary in which birds they include in the family. In the strictest sense, it includes only the 5 or 6 species of whipbirds and wedgebills (''Psophodes'' and '' Androphobus''), but some authors also include the quail-thrushes (''Cinclosoma''), 8 species of ground-dwelling birds found in Australia and New Guinea, and the jewel-babblers (''Ptilorrhoa''), 3 or 4 species found in rainforest in New Guinea. Others place them in their own family, the Cinclosomatidae. The Malaysian rail-babbler (''Eupetes macrocerus'') was formerly sometimes placed in this family, which would then be called Eupetidae. Taxonomy The quail-thrushes, jewel-babblers, whipbirds and wedgebills were traditionally included with the logrunners (''Orthonyx'') in the family Orthonychidae.Roberson, Don (2004Quail-thrushes Cinclosomatidae Bird Families of the World.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psophodes Nigrogularis
The black-throated whipbird (''Psophodes nigrogularis'') is a passerine bird found in several scattered populations in Southwest Australia. It is predominantly olive green in colour. It was formerly considered to be conspecific with the white-bellied whipbird (''Psophodes leucogaster''), so shares the common name "western whipbird". Taxonomy The black-throated whipbird was described by the English ornithologist John Gould in 1844 and given its current binomial name ''Psophodes nigrogularis''. Two subspecies are recognised. Both are under threat to some degree. *''Psophodes nigrogularis nigrogularis'': (Endangered) The Western heath subspecies is now restricted to a small patch east of Albany, having disappeared from large parts of its range due to land clearance.Garnett. p158 *''P. n. oberon'': (Rare) The Western mallee subspecies is found in scattered populations between the Stirling Ranges and Ravensthorpe. It is apparently common in the Fitzgerald River National Park.Garnet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clements Checklist
''The Clements Checklist of Birds of the World'' is a book by Jim Clements which presents a list of the bird species of the world. The most recent printed version is the sixth edition (2007), but has been updated yearly, the last version in 2022, and is published by Cornell University Press. Previous editions were published by the author's own imprint, Ibis Publishing. The Cornell Lab of Ornithology has provided annual updates since then, usually in August, and the most recent version is available online in several formats. These updates reflect the ongoing changes to bird taxonomy based on published research. ''Clements'' is the official list used by the American Birding Association for birds globally. eBird eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kangaroo Island
Kangaroo Island, also known as Karta Pintingga (literally 'Island of the Dead' in the language of the Kaurna people), is Australia's third-largest island, after Tasmania and Melville Island. It lies in the state of South Australia, southwest of Adelaide. Its closest point to the mainland is Snapper Point in Backstairs Passage, which is from the Fleurieu Peninsula. The native population of Aboriginal Australians that once occupied the island (sometimes referred to as the Kartan people) disappeared from the archaeological record sometime after the land became an island following the rising sea levels associated with the Last Glacial Period around 10,000 years ago. It was subsequently settled intermittently by sealers and whalers in the early 19th century, and from 1836 on a permanent basis during the British colonisation of South Australia. Since then the island's economy has been principally agricultural, with a southern rock lobster fishery and with tourism growing in impo ...

Psophodes
''Psophodes'' is a genus of five species of songbirds endemic to Australia, known as whipbirds and wedgebills. Description Whipbirds and wedgebills are collectively recognised in the genus ''Psophodes''.Toon, A., Joseph, L., & Burbidge, A., (2013). Genetic analysis of the Australian whipbirds and wedgebills illuminates the evolution of their plumage and vocal diversity. ''Emu''. Vol. 113, pp. 359-366. Wedgebills are divided into the chirruping wedgebill (''Psophodes cristatus'') and the chiming wedgebill (''Psophodes occidentalis''). Whipbirds are divided into the eastern whipbird (''Psophodes olivaceus'') and the western whipbird (''Psophodes nigrogularis'').

Endemic Birds Of Australia
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in birds. Patterns of endemism Family-level endemism is prominent in Australia. The Australasian biogeographic region has the highest number of endemic families of any zoogeographic region except the Neotropics, and many of these families are endemic to Australia itself — the country therefore stakes a strong claim to be the world's greatest hotspot of bird endemism. Australian endemic and near-endemic families The Australian endemic families are: * Emu (Dromaiidae), a well-known monotypic family; the emu is found in rural areas throughout the continent * Plains-wanderer (Pedionomidae), a monotypic family; plains-wanderer is restricted to arid inland areas in the southeast of Australia * Lyrebirds (Menuridae), two forest-dwelling species of southeast Australia * Scrub-birds (Atrichornithidae), two fore ...
