Fifty years ago, a young ornithologist named Steve Kress fell in love with penguins. After learning that hunting had eradicated their colonies on small, rocky islands off the coast of Maine, he resolved to bring them back. So began a decades-long quest that involved collecting chicks in Canada, flying them to Maine, raising them in coffee-can nests, transporting them to their new island home, watching over them as they grew, and then waiting - for years - to see if they would come back. This is the story of how the Puffin Project reclaimed a piece of our rich biological heritage, and how it inspired other groups around the world to help other species re-root in their native lands.
