Penguins as Marine Sentinels

This 2008 paper argues that penguins are marine sentinels. The largest Magellanic penguin colony in Punta Tombo, Argentina, has declined by 22% since 1987. Although oil pollution used to be a major threat, changes in shipping routes have greatly reduced this problem. Today, penguins are swimming farther from their nests to find food, showing that climate change and fishing are
