The 2005 Luc Jacquet documentary March of the Penguins won an Oscar for its depiction of emperor penguins' fifty-kilometer trek over sea ice to their breeding grounds. While such a trek may be common for emperors breeding in colonies around the Antarctic perimeter, it is not the case for the largest colonies in the Ross Sea. To understand emperor penguins here, we must follow them on four critical journeys, each with its own challenges and hazards. In this compelling and accessible book, comparative biologist Jerry Kooyman and writer and fellow Antarctic explorer Jim Mastro offer a detailed explanation of all four journeys. The first person to live in isolation for months to study these remarkable, deep-diving birds, Kooyman presents new stories and scientific descriptions with never-before-seen photographs and videos from the very edge. Kooyman has spent over two decades voyaging to the Antarctic and studying these penguins, and he is known among his fellow researchers at the Scripps Institution of Oceanography as "the penguin guy." With this book, readers will have a chance to explore alongside Kooyman and Mastro-and understand in new ways the lives of these remarkable and supremely adapted birds"--
