Samoan Whistler
The Samoan whistler (''Pachycephala flavifrons''), also known as the yellow-fronted whistler, is a species of bird in the family Pachycephalidae. It is endemic to Samoa, where found in forest, plantations and gardens. Taxonomy The Samoan whistler was originally described in the genus '' Eopsaltria''. It has been previously considered a subspecies In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morpholog ... of the Australian golden whistler, ''Pachycephala pectoralis'', as ''P. pectoralis flavifrons''. Description The Samoan whistler resembles the Australian golden whistler, but the male has blacker upperparts, yellow or white to the forehead, a dull black throat that is strongly mottled with yellow or white, and no black chest-band. The female resembles a duller version of the male with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titian Peale
Titian Ramsay Peale (November 17, 1799 – March 13, 1885) was an American artist, naturalist, and explorer from Philadelphia, Pennsylvania. He was a scientific illustrator whose paintings and drawings of wildlife are known for their beauty and accuracy. Peale was a member of several high-profile scientific expeditions. In 1819–20, he and Thomas Say accompanied Stephen Harriman Long on an expedition to the Rocky Mountains. He was also a member of the United States Exploring Expedition (1838–1842). Starting around 1855, Peale became an enthusiastic amateur photographer. Many of his photographs featured buildings and landscapes in and around Washington D.C. He joined a local club with other amateur photographers and participated in field trips, photo exchanges and contests. By the end of the Civil War, his interest in photography waned and he only occasionally took pictures. Biography Family and early life Peale was born on November 17, 1799 in Philosophical Hall, P ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species.

Pachycephalidae
The Pachycephalidae are a family of bird species that includes the whistlers, shrikethrushes, and three of the pitohuis, and is part of the ancient Australo-Papuan radiation of songbirds. The family includes 69 species that are separated into five genera. Its members range from small to medium in size, and occupy most of Australasia. Australia and New Guinea are the centre of their diversity and, in the case of the whistlers, the South Pacific islands as far as Tonga and Samoa and parts of Asia as far as India. The exact delimitation of boundaries of the family are uncertain, and one species, the golden whistler, has been the subject of intense taxonomic scrutiny in recent years, with multiple subspecies and species-level revisions. Taxonomy and systematics The family Pachycephalidae was introduced (as the subfamily Pachycephalinae) by the English ornithologist William Swainson in 1832. The genera ''Goldenface, Pachycare'', ''Hylocitrea'', the crested bellbird and the crested sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Samoa
Samoa, officially the Independent State of Samoa and known until 1997 as Western Samoa, is an island country in Polynesia, part of Oceania, in the South Pacific Ocean. It consists of two main islands (Savai'i and Upolu), two smaller, inhabited islands (Manono Island, Manono and Apolima), and several smaller, uninhabited islands, including the Aleipata Islands (Nuʻutele, Nuʻulua, Fanuatapu and Namua). Samoa is located west of American Samoa, northeast of Tonga, northeast of Fiji, east of Wallis and Futuna, southeast of Tuvalu, south of Tokelau, southwest of Hawaii, and northwest of Niue. The capital and largest city is Apia. The Lapita culture, Lapita people discovered and settled the Samoan Islands around 3,500 years ago. They developed a Samoan language and Culture of Samoa, Samoan cultural identity. Samoa is a Unitary state, unitary Parliamentary system, parliamentary democracy with 11 Districts of Samoa, administrative divisions. It is a sovereign state and a membe ...

Eopsaltria
''Eopsaltria'' is a genus of small forest passerines known in Australia as the yellow robins. They belong to the Australasian robin family Petroicidae. The name is derived from the Ancient Greek for "dawn singer/song" because of their dawn chorus. They are inquisitive and bold birds, and have been reported perching on the shoulders or boots of people in the bush. Open eucalyptus woodlands are their preferred habitat. The ornithologist John Gould likened the behaviour and mannerisms of the eastern and western yellow robin to those of the European robin. The name "yellow robin" itself was applied to the eastern yellow robin by the early settlers of New South Wales. Taxonomy and systematics The ornithologist William Swainson named the genus ''Eopsaltria'' in 1832, placing into it the bird that was then known as the yellow-breasted thrush (''Pachycephala australis''). Two species are currently classified within the genus: the eastern and western yellow robins, which have been alte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), 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 as 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 name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Australian Golden Whistler
The Australian golden whistler (''Pachycephala pectoralis'') or golden whistler, is a species of bird found in forest, woodland, mallee, mangrove and scrub in Australia (except the interior and most of the north). Most populations are resident, but some in south-eastern Australia migrate north during the winter. Its taxonomy is highly complex and remains a matter of dispute, with some authorities including as many as 59 subspecies of the golden whistler (one of the highest numbers of subspecies in any bird), while others treat several of these as separate species. This bird is also known as White-Throated Thickhead in older books. Taxonomy and systematics The Australian golden whistler was originally described in the genus ''Muscicapa'' by the English ornithologist John Latham in 1801. Subspecies The taxonomy of the golden whistler complex is difficult, and remains a matter of dispute. Some authorities include a wide range of – often strikingly different – taxa from Indones ...

Pachycephala
''Pachycephala'' is a genus of birds native to Oceania and Southeast Asia. They are commonly known as typical whistlers. Older guidebooks may refer to them as thickheads, a literal translation of the generic name, which is derived from the Ancient Greek terms ''pachys'' "thick" + ''kephale'' "head". This lineage originated in Australo-Papua and later colonized the Indonesian and Philippine archipelagos to the west and the Pacific archipelagos to the east. Taxonomy The genus ''Pachycephala'' was introduced in 1825 by the Irish zoologist Nicholas Vigors with the Australian golden whistler as the type species. The name is derived from the Ancient Greek ''pakhus'' meaning "large" or "thick" and ''kephalē'' meaning "head". The genus contains 53 species: * Olive whistler, ''Pachycephala olivacea'' * Red-lored whistler, ''Pachycephala rufogularis'' * Gilbert's whistler, ''Pachycephala inornata'' * Mangrove whistler, ''Pachycephala cinerea'' * Green-backed whistler, ''Pachycephal ...

Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...
