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 ...

Male Australian Plainhead Canary
Male (Mars symbol, symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot sexual reproduction, reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and Asexual reproduction, asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including Homo sapiens, humans, sex is determined genetics, genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evol ...

Selective Breeding
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carotenoid
Carotenoids (), also called tetraterpenoids, are yellow, orange, and red organic compound, organic pigments that are produced by plants and algae, as well as several bacteria, and Fungus, fungi. Carotenoids give the characteristic color to pumpkins, carrots, parsnips, maize, corn, tomatoes, Domestic Canary, canaries, flamingos, salmon, lobster, shrimp, and daffodils. Carotenoids can be produced from Lipid, fats and other basic organic metabolic building blocks by all these organisms. It is also produced by Endosymbiont, endosymbiotic bacteria in Whitefly, whiteflies. Carotenoids from the diet are stored in the fatty tissues of animals, and exclusively Carnivore, carnivorous animals obtain the compounds from animal fat. In the human diet, Small intestine#Absorption, absorption of carotenoids is improved when consumed with fat in a meal. Cooking carotenoid-containing vegetables in oil and shredding the vegetable both increase carotenoid bioavailability. There are over 1,100 known c ...

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.

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 ...

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.

Aviculture
Aviculture is the practice of keeping and breeding birds, especially of wild birds in captivity. Types There are various reasons that people get involved in aviculture. Some people breed birds to preserve a species. Some people breed parrots as companion birds, and some people breed birds to make a profit. Aviculture Aviculture is the practice of keeping birds (class ''Aves'') in captivity using controlled conditions, normally within the confines of an aviary, for hobby, business, research and conservation purposes. Some reasons for aviculture are: breeding birds to preserve the species because many avian species are at risk due to habitat destruction and natural disaster. Aviculture encourages conservation, provides education about avian species, provides companion birds for the public, and includes research on avian behaviour. Publications and avicultural societies Publications on aviculture include books on species which include pets, books on breeding and introductory b ...
