Gran Canaria Blue Chaffinch
The Gran Canaria blue chaffinch (''Fringilla polatzeki'') is a species of passerine bird in the finch family Fringillidae. It is endemic to Gran Canaria in Spain's Canary Islands. Taxonomy Until 2015, the species ''Fringilla teydea'' was classified with two subspecies: ''Fringilla teydea polatzeki'' from Gran Canaria and ''Fringilla teydea teydea'' from Tenerife. However, a study published in March 2016 showed that a classification as different species, ''Frigilla polatzeki'' and ''Fringilla teydea'', is justified.George Sangster, Felipe Rodríguez Godoy, C.

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 Hamburg, Germany 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) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of The Canary Islands
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 lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Fringilla
The genus ''Fringilla'' is a small group of finches from the Old World, which are the only species in the subfamily Fringillinae. The genus name ''Fringilla'' is Latin for "finch". Taxonomy The genus ''Fringilla'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name ''Fringilla'' is Latin for "finch". Linnaeus included 30 species in the genus (''Fringilla zena'' was listed twice) and of these the common chaffinch (''Fringilla coelebs'') is considered as the type species. Species The genus now contains four species: The common chaffinch is found primarily in forest habitats, in Europe, North Africa, and western Asia; the blue chaffinches are island endemics; and the brambling breeds in the northern taiga and southern tundra of Eurasia Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenerife Blue Chaffinch
The Tenerife blue chaffinch (''Fringilla teydea'') is a species of passerine bird in the finch family Fringillidae. It is endemic to Tenerife in Spain's Canary Islands. This bird is the natural symbol of this island, together with the Canary Islands dragon tree. Taxonomy Until 2015, the species ''Fringilla teydea'' was classified into two subspecies: ''Fringilla teydea polatzeki'' from Gran Canaria and ''Fringilla teydea teydea'' from Tenerife. However, a study published in March 2016 showed that a classification as different species, ''Fringilla polatzeki'' and ''Fringilla teydea'', is justified. Description Tenerife blue chaffinches resemble common chaffinches, but they are noticeably larger, and have a thicker bill. They are characteristically more uniform in their plumage, and they lack a dark cap. Females are a dull grey-brown, but can be distinguished from chaffinches by their weaker wing bars. Breeding males are unmistakable, with the namesake largely blue plumage and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broom (plant)
Genisteae is a tribe of trees, shrubs and herbaceous plants in the subfamily Faboideae of the family Fabaceae. It includes a number of well-known plants including broom, lupine (lupin), gorse and laburnum. The tribe's greatest diversity is in the Mediterranean, and most genera are native to Europe, Africa, the Canary Islands, India and southwest Asia. However, the largest genus, ''Lupinus'', is most diverse in North and South America. ''Anarthrophytum'' and ''Sellocharis'' are also South American and ''Argyrolobium'' ranges into India. Description The Genisteae arose 32.3 ± 2.9 million years ago (in the Oligocene). The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses. The tribe does not currently have a node-based definition, but several morphological synapomorphies have been identified: … bilabiate calyces with a bifid upper lip and a trifid lower lip, … the lack of an aril, or the presence of an aril but on the short ...

Canary Island Pine
''Pinus canariensis'', the Canary Island pine, is a species of gymnosperm in the conifer family Pinaceae. It is a large, evergreen tree, native and endemic to the outer Canary Islands of the Atlantic Ocean. Description ''Pinus canariensis'' is a large evergreen tree, growing to tall and diameter at breast height, exceptionally up to tall and diameter. The green to yellow-green leaves are needle-like, in bundles of three, long, with finely toothed margins and often drooping. A characteristic of the species is the occurrence of glaucous (bluish-green) epicormic shoots growing from the lower trunk, but in its natural area this only occurs as a consequence of fire or other damage. The cones are long, wide, glossy chestnut-brown in colour and frequently remaining closed for several years (serotinous cones). Its closest relatives are the chir pine (''P. roxburghii'') from the Himalayas, the Mediterranean pines '' P. pinea'', '' P. halepensis'', '' P. pinaster' ...

Common Chaffinch
The common chaffinch or simply the chaffinch (''Fringilla coelebs'') is a common and widespread small passerine bird in the finch family. The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is more subdued in colouring, but both sexes have two contrasting white wing bars and white sides to the tail. The male bird has a strong voice and sings from exposed perches to attract a mate. The chaffinch breeds in much of Europe, across the Palearctic to Siberia and in northwestern Africa. The female builds a nest with a deep cup in the fork of a tree. The clutch is typically four or five eggs, which hatch in about 13 days. The chicks fledge in around 14 days, but are fed by both adults for several weeks after leaving the nest. Outside the breeding season, chaffinches form flocks in open countryside and forage for seeds on the ground. During the breeding season, they forage on trees for invertebrates, especially caterpillars, and feed these to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 are distinguished from other orders of birds by the 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 clade of birds and among 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. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (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 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 ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
