Canaries were especially good for this purpose as, unlike finches, doves and mice, they reacted very quickly to carbon monoxide. While a mouse would not have a noticeable reaction until after up to 70 minutes to a carbon monoxide concentration of 0.77% in the air, a canary will fall off its perch after as little as 2.5 minutes from a ...

The waterschlager canary is the most robust example of unilateral syringeal dominance, creating song of which 90% of the syllables are produced by the left syrinx, as determined by recording respiratory pressure and airflow through each side during singing.

The red factor canary averages about 5 + 1 ⁄ 2 inches (14 cm) in length. This variety of canary tends to be bred for the novelty of its color, rather than for its song..
