Temotu Whistler
The Temotu whistler (''Pachycephala vanikorensis'') is a species of bird in the family Pachycephalidae, which is endemic to the Santa Cruz Islands of the Solomon Islands group. It was classified as a separate species in 2016 by the IOC. Two of its subspecies (''P. v. ornate'' and ''utupuae'') belonged previously to the former white-throated whistler and the nominate subspecies was a subspecies of the Melanesian Whistler. Taxonomy and systematics It was variably considered as subspecies of a widespread golden whistler ('' Pachycephala pectoralis'').Boles, W. E. (2007). Golden Whistler (Pachycephala pectoralis). pp. 421-423 in: del Hoyo, J.; Elliot, A. & Christie, D. eds (2007). ''Handbook of the Birds of the World''. Volume 12: ''Picathartes to Tits and Chickadees.'' Lynx Edicions, Barcelona.

Émile Oustalet
Jean-Frédéric Émile Oustalet (24 August 1844 – 23 October 1905 Saint-Cast) was a French zoologist.Hellmayr CE (1906). "Emile Oustalet bituary. ''Ornithologische Monatsberichte'' 14 (4): 57-59Scan Oustalet was born at Montbéliard, in the department of Doubs. He studied at the Ecole des Hautes-Etudes and his first scientific work was on the respiratory organs of dragonfly larvae. He was employed at the Muséum National d'Histoire Naturelle, where he succeeded Jules Verreaux as assistant-naturalist in 1873. In 1900 he succeeded Alphonse Milne-Edwards as Professor of Mammalogy. French ornithologist Émile Oustalet described a specimen from Branco as a separate species ''Passer brancoensis'' in 1883, which was recognised as the subspecies ''Passer iagoensis brancoensis'' by W. R. P. Bourne, who claimed to observe differences between Iago sparrows from different islands. He co-authored ''Les Oiseaux de la Chine'' (1877) with Armand David, and also wrote ''Les Oiseaux du Cambodg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

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 64 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 John Swainson in 1832. The genera ''Pachycare'', ''Hylocitrea'', the crested bellbird and the crested shriket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Santa Cruz Islands
The Santa Cruz Islands are a group of islands in the Pacific Ocean, part of Temotu Province of the nation of Solomon Islands discovered by the Spaniards. They lie approximately 250 miles (400 km) to the southeast of the Solomon Islands archipelago. The Santa Cruz Islands lie just north of the archipelago of Vanuatu, and are considered part of the Vanuatu rain forests ecoregion. Geography The term Santa Cruz Islands is sometimes used to encompass all of the islands of the present-day Solomon Islands province of Temotu. The largest island is Nendö, which is also known as Santa Cruz Island proper (505.5 km2, highest point , population over 5000). Lata, located on Nendö, is the largest town, and the capital of Temotu province. Other islands belonging to the Santa Cruz group are Vanikoro (173.2 km2, population 800, which is actually two islands, Banie and its small neighbor Teanu) and Utupua (69.0 km2, highest point , population 848). The Santa Cruz Isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiji Whistler
The Fiji whistler (''Pachycephala vitiensis'') is a species of bird in the family Pachycephalidae, endemic to Fiji. Taxonomy and systematics It was variably considered a subspecies of a widespread golden whistler ('' P. pectoralis'').Boles, W. E. (2007). Golden Whistler (Pachycephala pectoralis). pp. 421-423 in: del Hoyo, J.; Elliot, A. & Christie, D. eds (2007). ''Handbook of the Birds of the World''. Volume 12: ''Picathartes to Tits and Chickadees.'' Lynx Edicions, Barcelona. Three of the subspecies (P. v. kandavensis, lauana, and vitiensis) of the former white-throated whistler (''P. v. kandavensis, lauana, and vitiensis'') were lumped with the Fiji whistler in 2014 by the IOC. The Temotu whistler was formerly considered conspecific with the Fiji whistler. Subspecies Ten subspecies are recognized: * ''P. v. kandavensis'' - Ramsay, 1876: Originally described as a separate species.

Melanesian Whistler
The Melanesian whistler (''Pachycephala chlorura'') or Vanuatu whistler, is a species of passerine bird in the whistler family Pachycephalidae. It is found on the Loyalty Islands, Vanuatu, and Vanikoro in the far south-eastern Solomons. Taxonomy and systematics Until 2014, the Melanesian whistler was considered conspecific with the New Caledonian whistler. Formerly, it has also been treated as a subspecies of the golden whistler. Subspecies Four subspecies are recognized: * ''P. c. intacta'' - Sharpe, 1900: Originally described as a separate species. Found on Banks Islands and northern and central Vanuatu * ''P. c. cucullata'' - ( Gray, G.R., 1860): Originally described as a separate species in the genus ''Eopsaltria''.

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] |
Pachycephala Pectoralis
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)Ken Simpson, K., & N. Day. (1994). ''Field Guide to the Birds of Australia.'' 2nd edition. Christopher Helm. . 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. 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 – oft ...

Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned speci ...

Ernst Mayr
Ernst Walter Mayr (; 5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned Taxonomy (biology), taxonomist, tropical explorer, ornithologist, Philosophy of biology, philosopher of biology, and History of science, historian of science. His work contributed to the conceptual revolution that led to the Modern synthesis (20th century), modern evolutionary synthesis of Gregor Mendel, Mendelian genetics, systematics, and Charles Darwin, Darwinian evolution, and to the development of the Species, biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the ''species problem''. Ernst Mayr approached the problem with a new definition for species. In his book ''Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of Morphology (biology), morph ...
