Calocitta
The magpie-jays are a genus, ''Calocitta'', of the family Corvidae (crow-like birds) native to the southern part of North America. Sometimes placed in the genus ''Cyanocorax''. The two known species are known to form hybrids. The genus was introduced in 1841 by the English zoologist George Robert Gray with the white-throated magpie-jay (''Calocitta formosa'') as the type species. The name ''Calocitta'' combines the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC.

White-throated Magpie-jay
The white-throated magpie-jay (''Calocitta formosa'') is a large Central American species of magpie-jay. It ranges in Pacific-slope thorn forest from Jalisco, Mexico to Guanacaste, Costa Rica. Magpie-jays are noisy, gregarious birds, often traveling in easy-to-find flocks, mobbing their observers. Taxonomy The white-throated magpie-jay was formally described in 1827 by the English naturalist William John Swainson from a specimen that had been collected by the naturalist William Bullock in Temascaltepec, Mexico. Swainson coined the binomial name ''Pica formosa''. The specific epithet is from the Latin ''formosus'' meaning "beautiful". The white-throated magpie-jay is one of two magpie-jays now placed in the genus '' Calocitta'' that was introduced in 1841 by the English zoologist George Robert Gray with the white-throated magpie-jay as the type species. The white-throated magpie-jay hybridizes in Jalisco with the black-throated magpie-jay (''C. colliei''), with which it fo ...

Black-throated Magpie-jay
The black-throated magpie-jay (''Calocitta colliei'') is a strikingly long-tailed magpie-jay of northwestern Mexico. Taxonomy The black-throated magpie-jay was formally described in 1829 by the Irish zoologist Nicholas Aylward Vigors from a specimen collected at San Blas, Nayarit, Mexico. The specimen had been obtained by members of an expedition to explore the western coast of North America captained by Frederick William Beechey on '' HMS Blossom''. Vigors coined the binomial name ''Pica colleriei'', with the specific epithet chosen to honour Alexander Collie, the surgeon onboard the ''Blossom'', who had presented the specimen to the Zoological Society of London. The black-throated magpie-jay is now one of two species placed in the genus ''Calocitta'' that was introduced in 1841 by the English zoologist George Robert Gray. The species is monotypic: no subspecies are recognised. Description This species is 58.5 to 76.5 cm (23 to 30 inches) long, more than half of whi ...

Corvidae
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 133 species are included in this family. The genus ''Corvus'', including the crows, rooks, and ravens, makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other higher mammals. Their total brain-to-body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.Birding in India and South AsiaCor ...

George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''.

William John Swainson
William John Swainson FLS, FRS (8 October 1789 – 6 December 1855), was an English ornithologist, malacologist, conchologist, entomologist and artist. Life Swainson was born in Dover Place, St Mary Newington, London, the eldest son of John Timothy Swainson the Second (1756–1824), an original fellow of the Linnean Society. He was cousin of the amateur botanist Isaac Swainson.Etymologisches Worterbuch der botanischen Pflanzennamen by H. Genaust. Review by Paul A. Fryxell ''Taxon'', Vol. 38(2), 245–246 (1989). His father's family originated in Lancashire, and both grandfather and father held high posts in Her Majesty's Customs, the father becoming Collector at Liverpool. William, whose formal education was curtailed because of an impediment in his speech, joined the Liverpool Customs as a junior clerk at the age of 14."William Swainson F.R.S, F.L.S., Naturalist and Artist: Diaries 1808–1838: Sicily, Malta, Greece, Italy and Brazil."

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Cyanocorax
''Cyanocorax'' is a genus of New World jays, passerine birds in the family Corvidae. The generic name is derived from the Greek words κυανος (''kuanos''), meaning "dark blue," and κοραξ (''korax''), meaning "raven". It contains several closely related species that primarily are found in wooded habitats of Mexico and Central and South America, with the green jay just barely entering the United States. The genus ''Cyanocorax'' was introduced by the German zoologist Friedrich Boie in 1826, with the plush-crested jay as the type species. Species The genus contains 17 species: Some ornithologists treat the green jay and the Inca jay as conspecific Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organ ..., with ''C. yncas luxuosus'' as the green jay and ''C. yncas yncas'' as the ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
