Plectrophenax
''Plectrophenax'' is a small genus of passerine birds of the longspur family Calcariidae. Taxonomy The genus ''Plectrophenax'' was introduced in 1882 by the Norwegian born zoologist Leonhard Stejneger with the snow bunting as the type species. The name combines the Ancient Greek ''plēktron'' meaning "cock’s spur" with ''phenax'' meaning "imposter". Species The genus contains two species, which may be conspecific. They are high Arctic breeding seed-eating 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 lightweig ...s with stubby, conical bills, and much white in the plumage, especially in adult males.

Snow Bunting
The snow bunting (''Plectrophenax nivalis'') is a passerine bird in the family Calcariidae. It is an Arctic specialist, with a circumpolar Arctic breeding range throughout the northern hemisphere. There are small isolated populations on a few high mountain tops south of the Arctic region, including the Cairngorms in central Scotland and the Saint Elias Mountains on the southern Alaska-Yukon border, as well as the Cape Breton Highlands. The snow bunting is the most northerly recorded passerine in the world. Taxonomy The snow bunting was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He placed it with the buntings in the genus ''Emberiza'' and coined the binomial name ''Emberiza nivalis''. He specified the locality as Lapland. It is now placed in the genus ''Plectrophenax'' that was introduced in 1882 by the Norwegian born zoologist Leonhard Stejneger with the snow bunting as the type species. The genus name ''P ...

McKay's Bunting
McKay's bunting (''Plectrophenax hyperboreus'') is a passerine bird in the longspur family Calcariidae. It is most closely related to the snow bunting (''P. nivalis''). Hybrids between the two species have been observed, leading some authorities to treat McKay's as a subspecies of snow bunting. As the ''Plectrophenax'' buntings are nested within the ''Calcarius'' clade, their closest relatives are the longspurs. McKay's bunting breeds on two islands in the Bering Sea, St. Matthew and Hall islands, and winters on the western coast of the U.S. state of Alaska. Description This species closely resembles snow bunting in all plumages, but is whiter overall. The breeding plumage of the male is almost purely white, with only small areas of black on the wingtips and tail. The breeding female has a streaked back. Non-breeding birds also have warm brown patches on cheeks, crown, and the sides of the neck. McKay's bunting is larger on average than the snow bunting. It is long and weighs ...

Calcariidae
Calcariidae is a small family of passerine birds. It includes longspurs and snow buntings. There are six species in three genera worldwide, found mainly in North America and Eurasia. They are migratory and can live in a variety of habitats including grasslands, prairies, tundra, mountains, and beaches. Description Members of Calcariidae range in mass from around (the chestnut-collared longspur) to around ( McKay's bunting). Species have brown, grey, and white plumage, with dark brown or black irises. The legs of the snow bunting and McKay's bunting are dark gray or black, while legs of other species in the family range from dull pink to brown. Taxonomy The birds in Calcariidae were formerly assigned to the family Emberizidae (typically known as buntings in the Old World and sparrows in the New World). A 2008 phylogenetic study by Alström and colleagues confirmed that the members of this family form a clade quite separated from the Emberizidae, with affinities instead with ...

Longspur
The longspurs, genus ''Calcarius'', are a group of birds in the family Calcariidae. The name refers to the long claw on the hind toe of each foot. The genus formerly included the thick-billed longspur, ''Rhyncophanes mccownii'', which is now placed in a separate genus. These are chunky ground-feeding birds with long wings which are usually seen in open areas. Males declare ownership of a territory by singing during short flights over it. The male's breeding plumage is much brighter than his winter plumage. These birds gather in large flocks in winter. The longspurs are all found in North America; the Lapland longspur, or Lapland bunting, is also found in Europe and Asia. Species The species are: The genus name ''Calcarius'' is from Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power ...

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 ...

Leonhard Stejneger
Leonhard Hess Stejneger (30 October 1851 – 28 February 1943) was a Norwegian-born American ornithologist, herpetologist and zoologist. Stejneger specialized in vertebrate natural history studies. He gained his greatest reputation with reptiles and amphibians. Wetmore, Alexander (1945). "Leonhard Hess Stejneger (1851-1943)". ''Biographical Memoir. Nat. Acad. Sci.'' 24: 145-195PDF/ref> Early life and family Stejneger was born in Bergen, Norway. His father was Peter Stamer Steineger, a merchant and auditor; his mother was Ingeborg Catharine (née Hess). Leonhard was the eldest of seven children. His sister Agnes Steineger was a Norwegian artist. Until 1880, the Steineger family had been one of the wealthy families in Bergen; at that time business reverses led to the father declaring bankruptcy. Stejneger attended the Smith Theological School in Bergen from 1859 to 1860, and Bergen Latin School until 1869. His interests in zoology developed early. By age sixteen he had a print ...

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. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
