Black-headed Canary
The black-headed canary (''Serinus alario'') is a species of finch found in Lesotho, Namibia and South Africa. It is sometimes placed in the genus ''Alario'' as ''Alario alario'' Its habitat is dry open scrub and grassland, the edges of cultivation and suburban gardens. Description The black-headed canary is 12–15 cm in length. The adult male has rich brown upper parts and tail, a white hind collar, and mainly white underparts. The head and central breast are solidly black. The adult female is similar, but has a dull grey head, and is dark-streaked on the head and upper parts. It has a rich brown wing bar. The juvenile resembles the female, but is paler and has streaking on the breast and a weaker wing bar. The Damara canary (''Serinus leucolaema'') is often considered to be a subspecies of the black-headed canary. The male of that form has a strikingly different head pattern, with a white supercilium, and a white throat and foreneck with a black moustachial stripe. Th ...

Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler species, can be used to distinguish it from the very similar Radde's warbler. The dusky warbler's supercilium is sharply demarcated, whitish and narrow in front of the eye, becoming broader and more buffy towards the ...

Birds Described In 1758
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. Birds ...

Serinus
''Serinus'' is a genus of small birds in the finch family Fringillidae found in Europe and Africa. The birds usually have some yellow in their plumage. The genus was introduced in 1816 by the German naturalist Carl Ludwig Koch. Its name is New Latin for "canary-yellow". Many species were at one time assigned to the genus but it became clear from phylogenetic studies of mitochondrial and nuclear DNA sequences that the genus was polyphyletic. This was confirmed by Dario Zuccon and coworkers in a comprehensive study of the finch family published in 2012. The authors suggested splitting the genus into two monophyletic groups, a proposal that was accepted by the International Ornithologists' Union. The genus ''Serinus'' was restricted to the European serin and seven other species while a larger clade from Africa and Arabia was assigned to the resurrected genus ''Crithagra ''Crithagra'' is a genus of small passerine birds in the finch family (Fringillidae). They live in Africa and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serinus Pusillus
The red-fronted serin or fire-fronted serin (''Serinus pusillus'') is a small passerine bird in the finch family Fringillidae. It prefers high mountain regions and is 11–12 cm long. This bird breeds in the Caucasus and the higher mountains of Turkey and Iran, with vagrants occasionally reaching the Greek Eastern Aegean Islands in winter. This bird is also found in Ladakh and other parts of the Indian Himalayas. Outside the breeding season, it occurs in small flocks, typically seen searching through thistle patches. It is a popular cagebird, and escapees from captivity are occasionally found throughout Europe. The bird is variable in plumage, with adults resembling very dark redpolls. The foreparts are sooty and the forehead is red; juveniles have buff-brown heads. The call is a rapid, shrill "titihihihihihi", resembling that of a Linnet. The bird will breed in captivity and thrives on a diet of canary grass seed, millet, and other small seeds. They bathe daily if water i ...

Serinus Canicollis
The Cape canary (''Serinus canicollis'') is a small passerine bird in the finch family. It is a resident breeder in southern Africa and has been introduced to Mauritius and Réunion. Its habitat is fynbos, grassland and gardens, preferably in highland areas. It builds a compact cup nest in a scrub. The Cape canary is 11–13 cm in length. The adult male has a green back with black edging to the wing feathers wings and tail. The underparts, rump and tail sides are yellow, and the lower belly is white. The rear head and neck are grey, and the face is cinnamon. The female is similar, but with less grey on the head. The juvenile has greenish-yellow underparts with heavy brown streaking. This species is easily distinguished from the yellow-fronted canary by its lack of black face markings. The Cape canary is a common and gregarious seed-eater. Its call is ''tsit-it-it'', and the song is warbled goldfinch-like trills and whistles given in display flight or from a high perch. ...

Serinus Syriacus
The Syrian serin (''Serinus syriacus'') is a brightly coloured small passerine bird in the finch family Fringillidae. Description The Syrian serin is prettily coloured with bright yellow and pale grey feathers. The eyes are large and are surrounded by a bright yellow ring. The beak is grey and the legs are pale pinkish-grey. It has a long trilling call and may also chirp and twitter. Distribution and habitat Syrian serins breed in Syria, Lebanon, Israel and Jordan, at altitudes of between 900 and 1,900 metres. The population in Jordan makes local movements in winter, but the birds of Lebanon, Israel and Syria migrate to wintering grounds in Egypt, Turkey and Iraq. They inhabit rocky areas with oak and conifer shrubs or trees and frequent grasslands and fields feeding mainly on the seeds of annuals and grasses. In Southwestern Jordan, its main diet during winter is the seeds of ''Artemisia''. Phylogeny This species is phylogenetically included within the group of ''Serinus ...

Damara Canary
The Damara canary (''Serinus alario leucolaema'') is a small passerine bird in the finch family. Taxonomy The taxonomic status of this bird is uncertain. It is listed by the International Ornithologists' Union as a subspecies of the black-headed canary (''Serinus alario''). Description The Damara canary is 12–15 cm in length. The adult male has rich brown upper parts and tail, a white hind collar and mainly white underparts. The head pattern is striking; whereas the male black-headed canary has a solidly black head and central breast, the Damara canary has a white supercilium, and a white throat and foreneck with a black moustachial stripe. The black of the central breast is therefore separate from the black of the head. The adult female is similar, but has a dull grey head, and is dark-streaked on the head and upper parts. It has a rich brown wing bar. The female is similar to the female black-headed canary, but shows faint traces of the male head pattern. The juvenile ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat (ecology)
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
