Tenerife Goldcrest
The Tenerife goldcrest, ''Regulus regulus teneriffae'', (sometimes considered a separate species, ''R. teneriffae'') is a very small passerine bird in the kinglet family, closely resembling the goldcrest but with a broader black band across the forehead, slightly darker underparts and a longer bill. It breeds in the Canary Islands of Tenerife and La Gomera, where it is a non-migratory resident. It prefers Canary Island Pine forests, but also occurs in laurisilva forests. The populations on La Palma and El Hierro, previously thought to belong to this taxon, are now recognized as, at least, a distinct subspecies, the Western Canary Islands goldcrest ''R. (r.) ellenthalerae'' (Päckert ''et al.'', 2006), which evolved from an independent colonisation of the islands.

Henry Seebohm
Henry Seebohm (12 July 1832 – 26 November 1895) was an English steel manufacturer, and amateur ornithologist, oologist and traveller. Biography Henry was the oldest son of Benjamin Seebohm (1798–1871) who was a wool merchant at Horton Grange, Bradford. The family had moved to England from Bad Pyrmont in Germany. Henry's mother Estther Wheeler (1798–1864) was a granddaughter of William Tuke. The Seebohms were active in the Society of Friends and Henry schooled within the community in York. He worked initially in a grocery as an assistant but moved to Sheffield where he became a steel manufacturer. He married Maria, daughter of George John Healey, a merchant in Manchester on 19 January 1859. Natural history Henry became interested in natural history at school and continued to spend his spare time studying birds on his journeys. He travelled widely visiting Greece, Scandinavia, Turkey, and South Africa. His expeditions to the Yenisey tundra of Siberia were described in ...

El Hierro
El Hierro (), nicknamed ''Isla del Meridiano'' (the "Meridian Island"), is the farthest south and west of the Canary Islands (an autonomous community of Spain), in the Atlantic Ocean off the coast of Africa, with a population of 11,659 (2023). Its capital is Valverde. At , it is the second smallest of the eight main islands of the Canaries with La Graciosa being the smallest. Name The name ''El Hierro'', although spelled like the Spanish word for 'iron', is not related to that word. The ''H'' in the name of the metal is derived from the ''F'' of Latin ''ferrum'' (compare ''higo'' for 'fig'), a phonetic mutation that was complete by the end of the Middle Ages. The confusion with the name of the metal had effects on the international naming of the island. As early as the 16th century, maps and texts called the island after the word for 'iron' in other languages: Portuguese ''Ferro'', French ''l'île de Fer'', and Latin '' Insula Ferri''. Nevertheless, the origin of the nam ... [...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 ...

Endemic Fauna Of The Canary Islands
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Birds Described In 1883
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Regulus (bird)
''Regulus'' is a genus of bird in the family Kinglet, Regulidae. It contains most kinglet species aside from the ruby-crowned kinglet (''Corthylio calendula''), which was formerly classified in ''Regulus'' but is now known to belong to its own genus. Taxonomy The name of the genus is derived from the Latin ''regulus'', a diminutive of ''rex'', "a king", and refers to the characteristic orange or yellow crests of adult kinglets. Several forms have only recently had their status clarified. The Madeira firecrest was formerly considered to be a subspecies, ''R. i. madeirensis'', of the common firecrest ''R. ignicapillus''. A Phylogenetics, phylogenetic analysis based on the cytochrome b gene showed that the Madeiran form is distinct at the species level from the firecrest Subspecies#Nomenclature, nominate subspecies ''R. i. ignicapillus''. Cytochrome ''b'' gene divergence between the Madeira firecrest and the European bird is 8.5%, comparable with the divergence level between othe ...

Digital Object Identifier
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system ( Uniform Resource Identifier). They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications. A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. Thus, by being actionable and interoperable, a DOI differs from ISBNs or ISRCs which are identifiers only. The DOI system uses the indecs Content Model to represent metadata. The DOI for a document remains fixed over the lifetime of the document, whereas its location and other metadata may change. Referring to ...

Western Canary Islands Goldcrest
The Western Canary Islands goldcrest, ''Regulus regulus ellenthalerae'', is a very small passerine bird in the kinglet family. It is restricted to the western Canary Islands of La Palma and El Hierro where it is a non-migratory resident. Previously thought to be the same taxon as the Tenerife Goldcrest ''Regulus regulus teneriffae'', it was separated as a distinct subspecies of the goldcrest which apparently evolved from an independent colonisation of the islands 1.3–1.8 million years ago Million years ago, abbreviated as Mya, Myr (megayear) or Ma (megaannum), is a unit of time equal to (i.e. years), or approximately 31.6 teraseconds.

La Palma
La Palma (, ), also known as ''La isla bonita'' () and historically San Miguel de La Palma, is the most northwesterly island of the Canary Islands, a Spanish autonomous community and archipelago in Macaronesia in the North Atlantic Ocean. La Palma has an area of making it the fifth largest of the eight main Canary Islands. The total population at the start of 2023 was 84,338, of whom 15,522 lived in the capital, Santa Cruz de La Palma and 20,375 in Los Llanos de Aridane. Its highest mountain is the Roque de los Muchachos, at , being second among the peaks of the Canaries after the Teide massif on Tenerife. In 1815, the German geologist Leopold von Buch visited the Canary Islands. It was as a result of his visit to Tenerife, where he visited the Las Cañadas caldera, and then later to La Palma, where he visited the Taburiente caldera, that the Spanish word for cauldron or large cooking pot – "caldera" – was introduced into the geological vocabulary. In the center of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al.

Laurisilva
Laurel forest, also called laurisilva or laurissilva, is a type of subtropical forest found in areas with high humidity and relatively stable, mild temperatures. The forest is characterized by broadleaf tree species with evergreen, glossy and elongated leaves, known as "laurophyll" or "lauroid". Plants from the laurel family (Lauraceae) may or may not be present, depending on the location. Ecology Laurel and laurophyll forests have a patchy distribution in warm temperate regions, often occupying topographic refugia where the moisture from the ocean condenses so that it falls as rain or fog and soils have high moisture levels.Abstract at NASA – MODIS: Izquierdo, T; de las Heras, P; Marquez, A (2011).
