Oenanthe (bird)
The wheatears are passerine birds of the genus ''Oenanthe''. They were formerly considered to be members of the thrush family, Turdidae, but are now more commonly placed in the flycatcher family, Muscicapidae. This is an Old World group, but the northern wheatear has established a foothold in eastern Canada and Greenland and in western Canada and Alaska. Etymology The name "wheatear" is not derived from "wheat" or any sense of "ear", but is a folk etymology of "white" and "arse", referring to the prominent white rump found in most species. The genus name ''Oenanthe'' is derived from the Greek ''oenos'' (οἶνος) "wine" and ''anthos'' (ἄνθος) "flower". It refers to the northern wheatear's return to Greece in the spring just as the grapevines blossom. Taxonomy The genus ''Oenanthe'' was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816 with ''Oenanthe leucura'', the black wheatear, as the type species. The genus formerly included fewer sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ear (botany)
An ear is the grain-bearing tip part of the stem of a cereal plant, such as wheat or maize. It can also refer to "a prominent lobe in some leaves." The ear is a spike, consisting of a central stem on which tightly packed rows of flowers grow. These develop into fruits containing the edible seeds. In corn (maize), an ear is protected by leaves called husks. Inside an ear of corn is a corncob. In some species (including wheat), unripe ears contribute significantly to photosynthesis, in addition to the leaves lower down the plant. A parasite known as ''Anguina tritici'' (Ear Cockle) specifically affects the ears on wheat and rye by destroying the tissues and stems during growth. The parasite has been eradicated in most countries (with the exception of North Africa and West Asia) by using the crop rotation Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. It reduces reliance on one set of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folk Etymology
Folk etymology (also known as popular etymology, analogical reformation, reanalysis, morphological reanalysis or etymological reinterpretation) is a change in a word or phrase resulting from the replacement of an unfamiliar form by a more familiar one. The form or the meaning of an archaic, foreign, or otherwise unfamiliar word is reinterpreted as resembling more familiar words or morphemes. The term ''folk etymology'' is a loan translation from German language, German ''Volksetymologie'', coined by Ernst Förstemann in 1852. Folk etymology is a Productivity (linguistics), productive process in historical linguistics, language change, and social relation, social interaction. Reanalysis of a word's history or original form can affect its spelling, pronunciation, or meaning. This is frequently seen in relation to loanwords or words that have become archaic or obsolete. Examples of words created or changed through folk etymology include the English dialectal form wikt:sparrowgrass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capped Wheatear
The capped wheatear (''Oenanthe pileata'') is a small insectivorous passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. Description The capped wheatear is 17–18 cm long and weighs 32 g. Its legs and pointed bill are black. This common species is striking and unmistakable in appearance. The adult has a black cap, cheeks and breast band, and white eye stripe and throat. The rest of the underparts are white with buff on the flanks and lower belly. Like other wheatears, it has a distinctive tail pattern with a black feathers on the base and centre of the tail forming an inverted T against the otherwise white rump. The juvenile has a brown cap and cheeks, and the breast band is weak and diffuse. However, the breast band, larger size, and white at the base of the outer tail feathers distinguish it from the migrant northern wheatear, which is rare over most of the cap ...

Atlas Wheatear
The Atlas wheatear (''Oenanthe seebohmi''), also known as the black-throated wheatear or Seebohm's wheatear, is a small passerine bird which breeds in the Maghreb region of North Africa and winters in the western Sahel. It was formerly considered a subspecies of the northern wheatear (''O. oenanthe'') as ''O. o. seebohmi'', but was reclassified as a distinct species by the IOC in 2021. Taxonomy Seebohm's wheatear was formerly regarded as the North African subspecies of the widespread Northern wheatear of Eurasia, Greenland and northern North America, however, it is now regarded as a full species. Atlas wheatear has been proposed as the English common name for this species by the International Ornithological Committee. Description Adult male Atlas wheatears in breeding are very distinctive when compared to northern wheatear, having a black throat, face, lores and ear coverts, sometimes extending to the uppermost part of the breast, occasionally with some buff mixed in.

Northern Wheatear
The northern wheatear or wheatear (''Oenanthe oenanthe'') is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It is the most widespread member of the wheatear genus ''Oenanthe'' in Europe and North and Central Asia. The northern wheatear is a migratory insectivorous species breeding in open stony country in Europe and east across the Palearctic with footholds in northeastern Canada and Greenland as well as in northwestern Canada and Alaska. It nests in rock crevices and rabbit burrows. All birds spend most of their winter in Africa. Taxonomy and systematics The northern wheatear was first formally described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his ''Systema Naturae'' as ''Motacilla oenanthe''. The species is now placed in the genus '' Oenanthe'' that was introduced by the French ornithologist Louis Jean Pierre Vieill ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Lucien Bonaparte
Charles Lucien Jules Laurent Bonaparte, 2nd Prince of Canino and Musignano (24 May 1803 – 29 July 1857), was a French naturalist and ornithologist. Lucien and his wife had twelve children, including Cardinal Lucien Bonaparte. Life and career Bonaparte was the son of Lucien Bonaparte and Alexandrine de Bleschamp. Lucien was a younger brother of Napoleon I, making Charles the emperor’s nephew. Born in Paris, he was raised in Italy. On 29 June 1822, he married his cousin, Zénaïde, in Brussels. Soon after the marriage, the couple left for Philadelphia in the United States to live with Zénaïde's father, Joseph Bonaparte (who was also the paternal uncle of Charles). Before leaving Italy, Charles had already discovered a warbler new to science, the moustached warbler, and on the voyage he collected specimens of a new storm-petrel. On arrival in the United States, he presented a paper on this new bird, which was later named after Alexander Wilson. Bonaparte then set about ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Blackstart
__NOTOC__ The blackstart (''Oenanthe melanura'') is a chat found in desert regions in North Africa, the Middle East and the Arabian Peninsula. It is resident throughout its range. The blackstart is 14 cm long and is named for its black tail, which is frequently fanned; the rest of its plumage is bluish-grey or grey-brown (North African races being browner, Middle Eastern races bluer). The sexes are similar. The song is a clear melancholy whistle: ''CHURlee...TRUloo...CHURlee...TRUlur...'', with short phrases from the song used as a call. The habitats of blackstarts are rocky deserts and mountain slopes; they nest in rock crevices lay 3–4 eggs. They feed on insects, taken mainly on the ground. The blackstart is a confident species, unafraid of people. Taxonomy The first formal description of the blackstart was by the Dutch zoologist Coenraad Jacob Temminck in 1824 under the binomial name ''Saxicola melanura''. The blackstart was included as the type species in the genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
