From the 18th up to the 20th centuries, canaries and finches were used in the UK, Canada and the US in the coal mining industry to detect carbon monoxide.

[10] Evidence of hybridization has also been found between the domestic canary (S. canaria domestica) and the black-chinned siskin (Spinus barbatus) in captivity.

[11] Midway Atoll is home to a colony of feral yellow canaries, descended from pet birds introduced in 1909 by employees of the Commercial Pacific Cable Company.

[14] This means that in the Northern Hemisphere the show season generally begins in October or November and runs through December or January.

[citation needed] Mice were used as sentinel species for use in detecting carbon monoxide in British coal mining from around 1896,[15] after the idea had been suggested in 1895 by John Scott Haldane.

[22][23] 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.

Thus, canaries have served as model species for discovering how the vertebrate brain learns, consolidates memories, and recalls coordinated motor movements.

Fernando Nottebohm, a professor at the Rockefeller University in New York City, detailed the avian brain structures and pathways that are involved in the production of bird song.

Human testing could only provide limited sample size and the inherent variance of the host ⇔ repellent ⇔ insect interaction is too high.

[29] A number of other sports teams worldwide use variations of the name "Canaries", such as Atlético Morelia (Mexico), Botev Plovdiv (Bulgaria), Frosinone (Italy), Koper (Slovenia), FC Novi Sad (Serbia), Fenerbahçe (Turkey), Lillestrøm SK (Norway), Kedah FA (Malaysia), IAPE (Maranhão, Brazil), the Brazil national football team and the Brazil women's national football team.
