The domestic canary, often simply known as the canary (Serinus canaria forma domestica), is a domesticated form of the wild canary, a small songbird in the finch family originating from the Macaronesian Islands (the Azores, Madeira and the Canary Islands).
Canaries were first bred in captivity in the 17th century. They were brought over by Spanish sailors to Europe. This bird became expensive and fashionable to breed in courts of Spanish and English kings. Monks started breeding them and only sold the males (which sing). This kept the birds in short supply and drove the price up. Eventually, Italians obtained hens and were able to breed the birds. This made them very popular, resulting in many breeds arising, and the birds being bred all over Europe.
The same occurred in England. First the birds were only owned by the rich, but eventually the local citizens started to breed them and, again, they became very popular. Many breeds arose through selective breeding, and they are still very popular today for their voices.
The birds are named after Spain's Canary Islands, which derive their name from the Latin Insula Canaria (after one of the larger islands, Gran Canaria), meaning "island of dogs", due to its "vast multitudes of dogs of very large size".
Canaries are generally divided into three main groups:
- Colour-bred canaries (bred for their many colour mutations – Ino, Eumo, Satinette, Bronze, Ivory, Onyx, Mosaic, Brown, red factor etc.)
- Type canaries (bred for their shape and conformation – Australian plainhead, Berner, Border, Fife, Gibber Italicus, Gloster, Lancashire, Raza Española, Yorkshire, etc.)
- Song canaries (bred for their unique and specific song patterns – Spanish Timbrado, German Roller (also known as Harz Roller), Waterslager (also known as "Malinois"), American Singer, Russian Singer, Persian Singer).
While wild canaries are a yellowish-green colour, domestic canaries have been selectively bred for a wide variety of colours, such as yellow, orange, brown, black, white, and red (the colour red was introduced to the domesticated canary through hybridisation with the red siskin, a type of South American finch).
Canaries are judged in competitions following the annual molt in the summer. This means that in the Northern Hemisphere the show season generally begins in October or November and runs through December or January. Birds can only be shown by the persons who raised them. A show bird must have a unique band on its leg indicating the year of birth, the band number, and the club to which the breeder belongs.
There are many canary shows all over the world. The world show (C.O.M. - Confederation Ornithologique Mondiale) is held in Europe each year and attracts thousands of breeders. As many as 20,000 birds are brought together for this competition.
Canaries were once regularly used in coal mining as an early warning system. Toxic gases such as carbon monoxide or asphyxiant gases such as methane in the mine would affect the bird before affecting the miners. Signs of distress from the bird indicated to the miners that conditions were unsafe. The birds were generally kept in carriers which had small oxygen bottles attached to revive the birds, which were too valuable to be considered disposable. The use of miners' canaries in British mines was phased out in 1986.
The phrase "canary in a coal mine" is frequently used to refer to a person or thing which serves as an early warning of a coming crisis. By analogy, the term "climate canary" is used to refer to a species (called an indicator species) that is affected by an environmental danger prior to other species, thus serving as an early warning system for the other species with regard to the danger.
Use in research
Canaries have been extensively used in research to study neurogenesis, or the birth of new neurons in the adult brain, and also for basic research in order to understand how songbirds encode and produce song. Thus, canaries have served as model species for discovering how the vertebrate brain learns, consolidates memories, and recalls coordinated motor movements.
In organized crime, the canary symbolizes an informant who "sings to the police."
Norwich City, an English football team, is nicknamed "the Canaries" due to the city once being a famous centre for breeding and export of the birds. The club adopted the colours of yellow and green in homage. Jacob Mackley, of Norwich, won many prizes with birds of the local variety and shipped about 10,000 from Norwich to New York every year. In the early 1900s, he opened his aviaries to the public for three days and 10,000 people turned up. A number of other sports teams worldwide use variations of the name "Canaries", such as Frosinone (Italy), Koper (Slovenia), FC Novi Sad (Serbia), Fenerbahçe (Turkey), Lillestrøm SK (Norway), Kedah FA (Malaysia), the Brazil national football team and the Brazil women's national football team.
