Blue-headed Crested-flycatcher
The blue-headed crested flycatcher (''Trochocercus nitens'') is a species of bird in the family Monarchidae, native to the African tropical forest. Taxonomy and systematics Formerly, some authorities have placed the blue-headed crested flycatcher in the genus ''Terpsiphone''. Alternate names include the blue-headed flycatcher and blue-headed paradise-flycatcher. Subspecies Two subspecies are recognized: * Upper Guinea blue-headed crested flycatcher (''T. n. reichenowi'') - Sharpe, 1904: Originally described as a separate species. Found from Guinea to Togo * ''T. n. nitens'' - Cassin, 1859: Found from Nigeria to southern Sudan, Uganda, Democratic Republic of Congo and northwestern Angola References blue-headed crested flycatcher Birds of the African tropical rainforest blue-headed crested flycatcher The blue-headed crested flycatcher (''Trochocercus nitens'') is a species of bird in the family Monarchidae, native to the African tropical forest.

John Cassin
John Cassin (September 6, 1813 – January 10, 1869) was an American ornithologist from Pennsylvania. He worked as curator and Vice President at the Philadelphia Academy of Natural Sciences and focused on the systemic classification of the Academy's extensive collection of birds. He was one of the founders of the Delaware County Institute of Science and published several books describing 194 new species of birds. Five species of North American birds, a cicada and a mineral are named in his honor. Early life and education Cassin was born in Upper Providence Township, Pennsylvania on September 6, 1813. He was educated at the Westtown School in Westtown, Pennsylvania. His great Uncle, John Cassin, was a commodore in the U.S. Navy and served in the War of 1812. He served in the Union Army during the American Civil War and was held prisoner in the infamous Confederate Libby Prison in Richmond, Virginia. Career Cassin moved to Philadelphia in 1834 and became the head of a lith ... [...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] |
Tropical Forest
Tropical forests (a.k.a. jungle) are forested landscapes in tropical regions: ''i.e.'' land areas approximately bounded by the tropic of Cancer and Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorise. While forests in temperate areas are readily categorised on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of the world’s forests (45 percent), followed by ...

Terpsiphone
The paradise flycatchers (''Terpsiphone'') are a genus of birds in the family Monarchidae. The genus ranges across Africa and Asia, as well as a number of islands. A few species are migratory, but the majority are resident. The most telling characteristic of the genus is the long tail streamers of the males of many species. In addition to the long tails the males and females are sexually dimorphic and have rufous, black and white plumage. Taxonomy and systematics The genus ''Terpsiphone'' was introduced by the German zoologist Constantin Gloger in 1827. The type species was subsequently designated as the Indian paradise flycatcher. The name is from the Ancient Greek ''terpsi '' "delighting in" and ''phonos'' "voice". The genus contains 17 species: *Bedford's paradise flycatcher (''Terpsiphone bedfordi'') *Rufous-vented paradise flycatcher (''Terpsiphone rufocinerea'') *Red-bellied paradise flycatcher (''Terpsiphone rufiventer'') *Annobón paradise flycatcher (''Terpsiphone smi ...

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] |
Richard Bowdler Sharpe
Richard Bowdler Sharpe (22 November 1847 – 25 December 1909) was an English zoologist and ornithologist who worked as curator of the bird collection at the British Museum of natural history. In the course of his career he published several monographs on bird groups and produced a multi-volume catalogue of the specimens in the collection of the museum. He described many new species of bird and also has had species named in his honour by other ornithologists including Sharpe's longclaw (''Macronyx sharpei'') and Sharpe's starling (''Poeoptera sharpii''). Biography Richard was born in London, the first son of Thomas Bowdler Sharpe. His grandfather, Reverend Lancelot Sharpe was Rector of All Hallows Staining. His father was a publisher on Skinner Street and was best known for being the publisher of ''Sharpe's London Magazine'', an illustrated periodical (weekly but monthly from 1847). His care from the age of six was under an aunt, Magdalen Wallace, widow of the headmaster at Gramm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trochocercus
''Trochocercus'' is a genus of bird in the family Monarchidae. Described by Jean Cabanis in 1850, the name ''Trochocercus'' is a combination of the Greek words ''trokhos'' meaning "circular" or "round" and ''kerkos'', meaning "tail". Taxonomy and systematics Extant species After three former species were transferred to the genus ''Elminia'' in 2009, the genus ''Trochocercus'' now contains the following two remaining species: Former species Formerly, some authorities also considered the following species (or subspecies) as species within the genus ''Trochocercus'': * Bedford's paradise flycatcher (as ''Trochocercus bedfordi'') * Dusky crested flycatcher (as ''Trochocercus nigromitratus'') * White-bellied crested flycatcher (as ''Trochocercus albiventris'') * White-tailed crested flycatcher The white-tailed crested flycatcher (''Elminia albonotata'') is a species of bird in the flycatcher family Stenostiridae. It has a discontinuous distribution in eastern Africa. There are thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
