Think of penguins as ocean sentinels, says Dee Boersma -- they're on the frontlines of sea change. Sharing stories of penguin life and culture, she suggests that we start listening to what penguins are telling us.
Dee Boersma considers penguins ocean sentinels, helping us understand the effects of pollution, overfishing and climate change on the marine environment.
To Dee Boersma, penguins are more than charming birds in tuxes. Highly sensitive to variations in the ocean, penguins are sentinels, sounding the alarm on environmental threats to marine ecosystems. As director of the the Wildlife Conservation Society's Penguin Project, she has dedicated almost three decades to tracking them in the South Atlantic. Using "nametags" -- numbered metal bands -- Boersma and her team follow hundreds of individual penguins to learn where they go, what they eat and how they survive to the next breeding season.
