Why did they send canaries down mines?

More susceptible to toxic gases, such as carbon monoxide, the canaries warned miners by growing more distressed when the gas levels were rising too high, allowing the human miners to escape safely.

Why are canaries so sensitive to carbon monoxide?

They are so ingrained in the culture miners report whistling to the birds and coaxing them as they worked, treating them as pets. The canary is particularly sensitive to toxic gases such as carbon monoxide which is colourless, odourless and tasteless.
