Red Factor Canary
The red factor canary is a popular variety of canary. It is named after its colourful plumage, and is a 'color canary', bred for the novelty of its color rather than for its song. It is kept by those who want a pet, as well as those who enjoy showing. It is an active bird, hardy and very easy to keep; however, it is not easy to breed. First bred in the 1920s, it is the only colour canary that has an element of red as part of its plumage. It was developed as a cross between another type of finch, the now-endangered Venezuelan red siskin (''Spinus cucullatus''), and a yellow domestic canary (''Serinus canaria'' forma ''domestica''). A well-built bird, the red factor canary is about in length. These canaries are bred for showing, so therefore many versions of this canary exist today. They are divided into the Melanin and the Lipochrome classes. These are further divided into frosts (soft feather) or non-frosts (hard feather), which affects how bright their color appears.

Serinus Canaria Rosso Intenso
''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 monophyly, 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''. The genus contains eight species: References External links Serin videos, photos and sounds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Finch
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. Many birds in other families are also commonly called "finches". These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).Newton (1973), Clement ''et al.''

Red Siskin
The red siskin (''Spinus cucullatus'') is a small endangered finch native to tropical South America - in northern Colombia, northern Venezuela (where it is called the "cardenalito") and Guyana. It was common in the early 20th century, occurring throughout the foothills of northern Venezuela, but has now become extremely rare in a fragmented range. The population on Trinidad is believed to be extirpated, with no sightings since 1960. Habitat The red siskin is found in open country, forest edges and grassland with trees or shrubs. The female is believed to lay three greenish-white eggs in a grassy cup nest in a tree. Description The red siskin is about 10 cm long. The male is mainly deep red, with black on the head, throat, flight feathers and tail tip, and a whitish lower belly and under tail. The female is grey on the head, breast, and upper parts, apart from a red rump and upper tail. The breast is grey with reddish flanks, and the rest of the underparts, the wings and ta ...

Melanin
Melanin (; from el, μέλας, melas, black, dark) is a broad term for a group of natural pigments found in most organisms. Eumelanin is produced through a multistage chemical process known as melanogenesis, where the oxidation of the amino acid tyrosine is followed by polymerization. The melanin pigments are produced in a specialized group of cells known as melanocytes. Functionally, eumelanin serves as protection against Ultraviolet, UV radiation. There are five basic types of melanin: eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. The most common type is eumelanin, of which there are two types— brown eumelanin and black eumelanin. Pheomelanin, which is produced when melanocytes are malfunctioning due to derivation of the gene to its recessive format is a cysteine-derivative that contains polybenzothiazine portions that are largely responsible for the of red yellow tint given to some skin or hair colors. Neuromelanin is found in the brain. Research ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lipochrome
Lipofuscin is the name given to fine yellow-brown pigment Granule (cell biology), granules composed of lipid-containing residues of Lysosome, lysosomal digestion. It is considered to be one of the aging or "wear-and-tear" pigments, found in the liver, kidney, heart muscle, retina, adrenals, nerve cells, and ganglion cells. Formation and turnover Lipofuscin appears to be the product of the oxidation of unsaturated fatty acids and may be symptomatic of membrane damage, or damage to mitochondria and lysosomes. Aside from a large lipid content, lipofuscin is known to contain sugars and metals, including mercury (element), mercury, aluminium, iron, copper and zinc.Chris Gaugler,Lipofuscin", ''Stanislaus Journal of Biochemical Reviews'' May 1997 Lipofuscin is also accepted as consisting of oxidized proteins (30–70%) as well as lipids (20–50%). It is a type of lipochrome and is specifically arranged around the nucleus. The accumulation of lipofuscin-like material may be the result ...

Pet Store
A pet shop or pet store is a retail business which sells animals and pet care resources to the public. A variety of animal supplies and pet accessories are also sold in pet shops. The products sold include: food, treats, toys, collars, leashes, cat litter, cages and aquariums. Some pet stores provide engraving services for pet tags, which have the owner's contact information in case the pet gets lost. In the United Kingdom, United States and Canada, pet shops often offer both hygienic care (such as pet cleaning) and aesthetic services (such as cat and dog grooming). Some pet stores also provide tips on training and behaviour, as well as advice on pet nutrition. Pet stores are extremely popular in modern society. In 2004, according to the American Pet Products Manufacturers Association, in the pet industry, live animal sales reached approximately $1.6 billion. Moreover, in a 2003 survey in the US, merely 38% of U.S. pet shops claimed that they did not sell any live animals. Online ...

Atlantic Canary
The Atlantic canary (''Serinus canaria''), known worldwide simply as the wild canary and also called the island canary, common canary, or canary, is a small passerine bird belonging to the genus ''Serinus'' in the finch family, Fringillidae. It is native to the Canary Islands, the Azores, and Madeira. Wild birds are mostly yellow-green, with brownish streaking on the back. The species is common in captivity and a number of colour varieties have been bred. This bird is the natural symbol of the Canary Islands, together with the Canary Island date palm.

Australian Plainhead
The Australian plainhead is a breed of domestic canary that was created for show purposes. The variety was developed through selective breeding and remains the only breed of canary created in Australia. History The Australian plainhead has its roots in the old style Norwich canaries that originated in Norwich, England and became a popular show variety in Australia. In the 1930s, differences between the older show standard used by the breeders of Victoria, Australia and the more modern standards of the UK, created a bitter divide amongst Australian breeders of the Norwich canary. Decades later, after the modern Norwich had largely displaced the old-style birds from the Victorian show scene, a club was started in 1953 to preserve the old breed which was renamed the Australian plainhead. By 1991, the number of Australian plainhead canaries in Australia had dropped to around 460 birds. Whilst the Australian plainhead remains a rare breed, it is now far more widespread with birds ...

Harz Roller
Harz Roller (german: link=no, Harzer Roller ) is the name of a breed of domestic canary bred in the Upper Harz mountains of Germany. The birds were bred in the Upper Harz between Lautenthal and Sankt Andreasberg in the middle of the 19th century and achieved European-wide fame. Since 2001 there has been a Harz Roller Museum in Sankt Andreasberg. By patient breeding, a breed of canary was able to be produced that had a pleasant, melodious song, full of variety and delivered with an apparently closed beak. Different types of canaries can breed with each other, especially including the Harz Roller and the Spanish Timbrado. Miner's canary The breeding and sale of this popular breed of canary was an important secondary occupation for mining people, as was the making of cages for the birds. In the second half of the 19th century, the breeding and sale of these canaries boomed. In contrast to widespread legend, the birds were ''not'' used in the mines to indicate the presence o ...
