Canaries As Poisonous Gas Detectors
n the late 1890s, [John] Haldane began experimenting on small animals like white mice and canaries [to detect carbon monoxide]. Small animals have faster metabolism rate, and hence show the effects of carbon monoxide poisoning much earlier even in the presence of small quantities of the noxious gas. Canaries are especially good at detecting toxins in the air because of their specialized respiratory system.
