Miners used canaries in cages to detect hazardous atmospheres in the mines because canaries are more sensitive to mining gasses than people are. If the canary collapsed, that meant that there were poisonous gasses in the tunnel, and the miners would evacuate until the mine had been ventilated and was safe again.
Miners often took canaries underground with them. Canaries were used as an early warning system for dangerous gases such as carbon monoxide in the mines. If the bird stopped singing or died, it was a sign for the miners to evacuate the mine immediately.
The Davy lamp helped canaries because it was a safety lamp used in coal mines to detect the presence of dangerous gases like carbon monoxide. Canaries are sensitive to these gases, so if the bird showed signs of distress or illness, miners would know to evacuate the mine to avoid danger.
