Sooty Shrikethrush
The sooty shrikethrush (''Colluricincla tenebrosa'') is a species of bird in the family Pachycephalidae. It is found in the New Guinea Highlands. Its natural habitat is subtropical or tropical moist montane forests. Taxonomy and systematics The sooty shrikethrush was formerly known as ''Colluricincla umbrina'' (Reichenow, 1915), as the name ''Rectes tenebrosus'' Hartlaub & Finsch, 1868 (the morningbird) has priority over ''Pachycephala tenebrosa'' Rothschild, 1911 (the sooty shrikethrush) when the two species are placed in the same genus; with the transfer of the morningbird from the genus ''Colluricincla'' to ''Pachycephala'' in 2013, the sooty shrikethrush reverted from ''umbrina'' to the older name ''tenebrosa''. Alternate names for the sooty shrikethrush include the obscure shrike-thrush, sooty robin-whistler and sooty whistler. Subspecies Two subspecies are recognized: * ''C. t. atra'' - (Rothschild, 1931): Found on northern slopes of central New Guinea mountains * ''C. t. ...

Walter Rothschild, 2nd Baron Rothschild
Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoologist and soldier, who was a member of the Rothschild family. As a Zionist leader, he was presented with the Balfour Declaration, which pledged British support for a Jewish national home in Palestine. Rothschild was the president of the Board of Deputies of British Jews from 1925 to 1926. Early life Walter Rothschild was born in London as the eldest son and heir of Emma Louise von Rothschild and Nathan Rothschild, 1st Baron Rothschild, an immensely wealthy financier of the international Rothschild financial dynasty and the first Jewish peer in England. The eldest of three children, Walter was deemed to have delicate health and was educated at home. As a young man, he travelled in Europe, attending the University of Bonn for a year before entering Magdalene College, Cambridge. In 1889, leaving Cambridge after two years, he was ...

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] |
New Guinea Highlands
The New Guinea Highlands, also known as the Central Range or Central Cordillera, is a long chain of mountain ranges on the island of New Guinea, including the island's tallest peak, Puncak Jaya , the highest mountain in Oceania. The range is home to many intermountain river valleys, many of which support thriving agricultural communities. The highlands run generally east-west the length of the island, which is divided politically between Indonesia in the west and Papua New Guinea in the east. Geography The Central Cordillera, some peaks of which are capped with ice, consists of (from east to west): the Central Highlands and Eastern Highlands of Papua New Guinea including the Owen Stanley Range in the southeast, whose highest peak is Mount Victoria at 4,038 metres (13,248 feet), the Albert Victor Mountains, the Sir Arthur Gordon Range, and the Bismarck Range, whose highest peak is Mount Wilhelm at 4,509 metres (14,793 feet), which is an extinct volcano with a crater lake; the Star ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morningbird
The morningbird (''Pachycephala tenebrosa'') is a songbird species in the family Pachycephalidae. Taxonomy and systematics The morningbird was previously placed in the genus ''Colluricincla'' until 2013, when it was transferred to ''Pachycephala''. Some authorities have placed the morningbird in the genus '' Pitohui'' and it is sometimes placed in its own monotypic genus, ''Malacolestes''. Alternate names for the morningbird include the brown pitohui, morning pitohui, morning whistler, Palau morningbird and Palau pitohui. Distribution and habitat The morningbird is endemic to the islands of Babelthuap, Koror, Garakayo, Peleliu and Ngabad in Palau. Its natural habitat is deep primary tropical moist lowland forests. The species is non-migratory Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Principle Of Priority
270px, '' valid name. Priority is a fundamental principle of modern botanical nomenclature and zoological nomenclature. Essentially, it is the principle of recognising the first valid application of a name to a plant or animal. There are two aspects to this: # The first formal scientific name given to a plant or animal taxon shall be the name that is to be used, called the valid name in zoology and correct name in botany (principle of synonymy). # Once a name has been used, no subsequent publication of that name for another taxon shall be valid (zoology) or validly published (botany) (principle of homonymy). Note that nomenclature for botany and zoology is independent, and the rules of priority regarding homonyms operate within each discipline but not between them. There are formal provisions for making exceptions to the principle of priority under each of the Codes. If an archaic or obscure prior name is discovered for an established taxon, the current name can be declared ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 and systematics Extant species There are forty-eight species of whistlers: * Olive whistler (''Pachycephala olivacea'') * Red-lored whistler (''Pachycephala rufogularis'') * Gilbert's whistler (''Pachycephala inornata'') * Mangrove whistler (''Pachycephala cinerea'') * Biak whistler (''Pachycephala melanorhyncha'') * Green-backed whistler (''Pachycephala albiventris'') * White-vented whistler (''Pachycephala homeyeri'') * Island whistler (''Pachycephala phaionota'') * Rusty whistler (''Pachycephala hyperythra'') * ...

Colluricincla
A shrikethrush, also spelt shrike-thrush, is any one of eleven species of songbird that is a member of the genus ''Colluricincla''. They have nondescript, predominantly brown or grey, plumage, but are accomplished singers, their calls described as "strong, mellow and beautiful." Shrikethrushes are generally insectivorous, though have been recorded eating molluscs and berries. They build cup-shaped nests in the forks of trees. Taxonomy and systematics Nicholas Aylward Vigors and Thomas Horsfield described the genus in 1827, coining the genus name from the Ancient Greek words ''collurio'' "shrike" and ''cinclos'' "thrush". Noting the beak, they thought it related to shrikes or vangas, though its form was reminiscent of thrushes. Shrikethrushes were commonly known as colluricinclas in the 19th century, but their current name was in use by the late 19th century. Molecular studies by Norman and colleagues in 2009 and Jønsson and colleagues in 2010 show the shrikethrushes to lie withi ...
