Red Kite
The red kite (''Milvus milvus'') is a bird of prey in the family Accipitridae, which also includes many other Diurnality, diurnal Bird of prey, raptors such as eagles, buzzards, and harrier (bird), harriers. The species currently breeds only in Europe, though it formerly also bred in west Asia and northwest Africa. Historically, it was only resident in the milder parts of its range in western Europe and northwestern Africa, whereas all or most red kites in northern mainland Europe wintered to the south and west, some also reaching western Asia, but an increasing number of northern birds now remain in that region year-round. Vagrancy (biology), Vagrants have reached north to Finland and south to Israel, Libya and Gambia. Taxonomy The red kite was described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, 10th edition of his ''Systema Naturae'' under the Binomial nomenclature, binomial name ''Falco milvus''. The word ''milvus'' was the Latin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemnitz
Chemnitz (; from 1953 to 1990: Karl-Marx-Stadt (); ; ) is the third-largest city in the Germany, German States of Germany, state of Saxony after Leipzig and Dresden, and the fourth-largest city in the area of former East Germany after (East Berlin, East) Berlin, Leipzig, and Dresden. The city lies in the middle of a string of cities sitting in the densely populated northern Ore Mountain Foreland, foreland of the Elster Mountains, Elster and Ore Mountains, stretching from Plauen in the southwest via Zwickau, Chemnitz and Freiberg to Dresden in the northeast, and is part of the Central German Metropolitan Region. Located in the Ore Mountain Basin, the city is surrounded by the Ore Mountains to the south and the Central Saxon Hills, Central Saxon Hill Country to the north. The city stands on the Chemnitz River, which is formed through the confluence of the rivers Zwönitz (river), Zwönitz and Würschnitz in the borough of Altchemnitz.

Systema Naturae
' (originally in Latin written ' with the Orthographic ligature, ligature æ) is one of the major works of the Sweden, Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard Bauhin, Gaspard and Johann Bauhin, Johann, Linnaeus was the first to use it consistently throughout his book. The first edition was published in 1735. The full title of the 10th edition (1758), which was the most important one, was ', which appeared in English in 1806 with the title: "A General System of Nature, Through the Three Grand Kingdoms of Animals, Vegetables, and Minerals, Systematically Divided Into their Several Classes, Orders, Genera, Species, and Varieties, with their Habitations, Manners, Economy, Structure and Peculiarities". The 10th edition of Systema Naturae, tenth edition of this book (1758) is considered the starting point of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Yellow-billed Kite
The yellow-billed kite (''Milvus aegyptius'') is the Afrotropic counterpart of the black kite (''Milvus migrans''), of which it is most often considered a subspecies. However, DNA studies suggest that the yellow-billed kite differs significantly from black kites in the Eurasian clade, and should be considered as a separate, allopatric species. Taxonomy The yellow-billed kite was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He specified that the bird was found in Egypt, placed it with the eagles, falcons and relatives in the genus '' Falco'' and coined the binomial name ''Falco aegyptius''. Unusually, Gmelin did not cite a source for his information. The yellow-billed kite is now one of three kites placed in the genus '' Milvus'' that was introduced in 1799 by the French naturalist Bernard Germain de Lacépède. There are two subspecies: The yellow-billed kite was formerl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Kite
The black kite (''Milvus migrans'') is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors. It is thought to be the world's most abundant species of Accipitridae, although some populations have experienced dramatic declines or fluctuations. Current global population estimates run up to 6.7 million individuals. Unlike others of the group, black kites are opportunistic hunters and are more likely to scavenge. They spend much time soaring and gliding in thermals in search of food. Their angled wing and distinctive forked tail make them easy to identify. They are also vociferous with a shrill whinnying call. The black kite is widely distributed through the temperate and tropical parts of Eurasia and parts of Australasia and Oceania, with the temperate region populations tending to be migratory. Several subspecies are recognized and formerly had their own English names. The European populations are small, but the South Asian popula ...

Cape Verde
Cape Verde or Cabo Verde, officially the Republic of Cabo Verde, is an island country and archipelagic state of West Africa in the central Atlantic Ocean, consisting of ten volcanic islands with a combined land area of about . These islands lie between west of Cap-Vert, the westernmost point of continental Africa. The List of islands of Cape Verde, Cape Verde islands form part of the Macaronesia ecoregion, along with the Azores, the Canary Islands, Madeira and the Savage Isles. The Cape Verde archipelago was uninhabited until the 15th century, when Portuguese Empire, Portuguese explorers colonized the islands, establishing one of the first Age of Discovery, European settlements in the tropics. Due to its strategic position, Cape Verde became a significant location in the Atlantic slave trade, transatlantic slave trade during the 16th and 17th centuries. The islands experienced economic growth during this period, driven by their role by the rapid emergence of merchants, priva ...

Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in the Free and Hanseatic City of Hamburg on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), 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 as 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 name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Tautonym
A tautonym is a scientific name of a species in which both parts of the name have the same spelling, such as '' Rattus rattus''. The first part of the name is the name of the genus and the second part is referred to as the ''specific epithet'' in the ''International Code of Nomenclature for algae, fungi, and plants'' and the ''specific name'' in the ''International Code of Zoological Nomenclature''. Tautonymy (i.e., the usage of tautonymous names) is permissible in zoological nomenclature (see List of tautonyms for examples). In past editions of the zoological code, the term tautonym was used, but it has now been replaced by the more inclusive "tautonymous names"; these include trinomial names for subspecies such as '' Gorilla gorilla gorilla'' and '' Bison bison bison''. Tautonyms can be formed when animals are given scientific names for the first time, or when they are reclassified and given new scientific names. An example of the former is the hidden mirror skipper of Braz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...
