For decades, coal miners relied on canaries to warn them about deadly carbon monoxide underground. Canaries were retired from that work at the end of the 20th century, but today scientists still rely on certain organisms, referred to as sentinels, to reveal hidden environmental threats. In this episode, we trace the history of the canary in the coal mine to today and explore how researchers use songbirds, mussels, and oysters to monitor mercury, industrial pollution, and other contaminants that can linger in ecosystems for generations.
