Fringilla Polatzeki
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, ''Fringilla 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 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] |

Birds Described In 1905
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have 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 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 furth ...

Fringilla
The genus ''Fringilla'' is a small group of eight species of finches from the Old World. It is the only genus in the subfamily Fringillinae. Taxonomy The genus ''Fringilla'' was described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, 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 Eurasian chaffinch (''Fringilla coelebs'') is considered as the type species. Species By the early 20th century, the genus was considered to include just three species, with the other species included by Linnaeus transferred to other genera. In 2016, it was proposed that the extremely rare Gran Canaria blue chaffinch subspecies ''F. teydea polatzeki'' be treated as a separate species, thus accepting a fourth species, ''F. polatzeki''. A major genetic, morphological, and behavioural study in 2021 then divided the former c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Broom (plant)
Genisteae is a tribe (biology), 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, Lupinus, lupine (lupin), Ulex, gorse and laburnum. The tribe's greatest diversity is in the Mediterranean, and most genera are native plant, 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 monophyly, monophyletic clade in molecular phylogenetics, molecular phylogenetic analyses. The tribe does not currently have a node-based definition, but several morphological synapomorphy, synapomorphies have been identified: … bilabiate calyces with a bifid ...

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 girth ( 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 epicormic shoots with single (not in threes) glaucous (bluish-green) juvenile leaves 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.&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Polatzek
Johann Polatzek (1838 – 17 February 1927) was an Austrian army captain and collector of natural history specimens. He collected birds and insects from the Canary Islands and the Gran Canary finch (''Fringilla polatzeki'') was described from his collections by Ernst Hartert. Polatzek served in the 3rd company of the k. u. k. Feldjägerbataillons Nr. 26 and saw action in the Balkans in 1882. From 1894 to 1900 he travelled in the Balkans, collecting specimens of natural history in his spare time. From 1902 to 1905 he visited the Canary Islands in 1910 he visited Pityusic. About 1500 bird specimens that he collected are held at the Natural History Museum in Vienna. He also sold specimens to Walter Rothschild Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoologist, and soldier, who was a member of the Rothschild family.

Common Chaffinch
The Eurasian chaffinch, 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. 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 their ... [...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 a ... [...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. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three suborders: New Zealand wrens; Suboscines, primarily found in North and South America; and songbirds. Passerines originated in the ...
