Chestnut-throated Flycatcher
The chestnut-throated flycatcher (''Myiagra castaneigularis'') is a species of bird in the monarch-flycatcher family Monarchidae. The species is endemic to Fiji. Taxonomy and systematics In 2016, the chestnut-throated flycatcher was recognized as a new species after being split from the azure-crested flycatcher. Subspecies Two subspecies are recognized: * ''M. c. castaneigularis'' - Layard, 1876: Found on Vanua Levu (northern Fiji) * ''M. c. whitneyi'' - Mayr, 1933: Found on Viti Levu Viti Levu (pronounced ) is the largest island in the Republic of Fiji.

Edgar Leopold Layard
Edgar Leopold Layard MBOU, (23 July 1824 – 1 January 1900) was a British diplomat and a naturalist mainly interested in ornithology and to a lesser extent the molluscs. He worked for a significant part of his life in Ceylon and later in South Africa, Fiji and New Caledonia. He studied the zoology of these places and established natural history museums in Sri Lanka and South Africa. Several species of animals are named after him. Early life and education Born in the Berti Palace, Florence, Italy, to an English family of Huguenot descent, Layard was the youngest of seven sons (two of the earlier siblings died in infancyLayard, E.L. Unpublished autobiography. MS at Blacker-Wood library, McGill University, Canada.) of Henry Peter John Layard of the Ceylon Civil Service (the son of Charles Peter Layard, dean of Bristol, and grandson of Daniel Peter Layard the physician) with his wife Marianne, a daughter of Nathaniel Austen, banker, of Ramsgate. Through her, he was par ... [...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 ...

Monarchidae
The monarchs (family Monarchidae) comprise a family of over 100 passerine birds which includes shrikebills, paradise flycatchers, and magpie-larks. Monarchids are small insectivorous songbirds with long tails. They inhabit forest or woodland across sub-Saharan Africa, south-east Asia, Australasia and a number of Pacific islands. Only a few species migrate. Many species decorate their cup-shaped nests with lichen. Taxonomy and systematics Some of the one hundred or more species making up the family were previously assigned to other groups, largely on the basis of general morphology or behaviour. The magpie-lark, for example, was assigned to the same family as the white-winged chough, since both build unusual nests from mud rather than vegetable matter. That family, Grallinidae, is now considered a synonym of Monarchidae. It was formerly considered to have four species. The magpie-lark and the torrent-lark were moved into Monarchidae, into the genus ''Grallina'', on the basis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azure-crested Flycatcher
The azure-crested flycatcher (''Myiagra azureocapilla'') or the blue-crested flycatcher, is a species of bird in the monarch flycatcher family Monarchidae. It is endemic to Fiji, where it is found on Taveuni. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. Taxonomy The azure-crested flycatcher was first described in 1875 by ornithologist Edgar Leopold Layard, Administrator of the Government of the Colony of Fiji at the time. Its specific epithet is derived from the Latin ''azureus'' 'blue', and ''capillus'' 'of the head'. It is also commonly known as the blue-crested broadbill, or the azure-crested flycatcher. It is a member of a group of birds termed monarch flycatchers. This group is considered either as a subfamily Monarchinae, together with the fantails as part of the drongo family Dicruridae, or as a family Monarchidae in its own right. They are not closely related to their namesakes either, the Ol ... [...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] |
Vanua Levu
Vanua Levu (pronounced ), formerly known as Sandalwood Island, is the second largest island of Fiji. Located to the north of the larger Viti Levu, the island has an area of and a population of 135,961 . Geology Fiji lies in a tectonically complex area between the Australian Plate and the Pacific Plate. The Fiji Platform lies in a zone bordered with active extension fault lines around which most of the shallow earthquakes were centred. These fault lines are the Fiji Fracture Zone (FFZ) to the north, the 176° Extension Zone (176°E EZ) to the west, and the Hunter Fracture Zone (HFZ) and Lau Ridge to the east. Mio-Pliocene sandstones and marl grade into epiclastics and andesitic volcanics of the Suva Group. The Group forms the Korotini Tableland in the middle of the island, it includes the peaks of Seseleka (), Ndelanathau (), Nararo (), Valili (), Mariko (), Mount Nasorolevu (), Ndikeva (), and Uluingala (). The Pliocene Undu Group in the northeastern portion of the island ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Viti Levu
Viti Levu (pronounced ) is the largest island in the Republic of Fiji. It is the site of the nation's capital, Suva, and home to a large majority of Fiji's population. Geology Fiji lies in a tectonically complex area between the Australian Plate and the Pacific Plate. The Fiji Platform lies in a zone bordered by active extension fault lines, around which most of the shallow earthquakes in the area have been centred. These fault lines are: the Fiji Fracture Zone (FFZ) to the north; the 176° Extension Zone (176°E EZ) to the west; and the Hunter Fracture Zone (HFZ) and Lau Ridge to the east. The oldest rocks on the island are those formed during the Eocene and Lower Miocene epochs that belong to the Wainimala group. The lower portion of the group is made up of volcanic flows and volcanoclastics, which grade from basalt to trachyte and rhyolite. Geographically, this group is found south of Nadi, including on the peaks of Koromba (at 3528 feet high) and Natambumgguto (at 1242 ...

Myiagra
''Myiagra'' is a genus of passerine birds in the family Monarchidae, the monarch flycatchers, native to Australasia, sometimes referred to as the broad-billed flycatchers or simply broadbills. Taxonomy The genus ''Myiagra'' was introduced in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield. The name combines the Ancient Greek ''muia'' meaning "a fly" and ''agreō'' meaning "to seize". Myiagros was also the name of a Greek god. The type species was designated by George Robert Gray in 1840 as the leaden flycatcher. Species The genus contains 22 species include one that is now extinct: * Oceanic flycatcher (''Myiagra oceanica'') * Palau flycatcher (''Myiagra erythrops'') * † Guam flycatcher (''Myiagra freycineti'') (extinct) * Pohnpei flycatcher (''Myiagra pluto'') * Moluccan flycatcher (''Myiagra galeata'') * Biak black flycatcher (''Myiagra atra'') * Leaden flycatcher (''Myiagra rubecula'') * Steel-blue flycatcher (''Myiagra ferrocyanea'') * Makira flycatcher ('' ...

Endemic Birds Of Fiji
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] |
