A dangerous profession continued.

Life for an actual canary in a coal mine could be described in three words: “short but meaningful.” Early coal mines did not feature ventilation systems, so legend has it that miners would bring a caged canary into new coal seams. Canaries are especially sensitive to methane and carbon monoxide, which made them ideal for detecting any dangerous gas build-ups. As long as the bird kept singing, the miners knew their air supply was safe. A dead canary signaled an immediate evacuation.

I wonder if the canary did the swan song at the end?

Canaries go in but not necessarily go out?

I wonder if there is a monument for the canary somewhere that saved the miners?

I wonder if the miners gave them pet names?
