"Informative sidebars, graphs, and charts explain technical terms in clear language. An annotated bibliography and gorgeous photos round out this treat of a book, which describes what it was like to live among emperor penguins and the challenges and rewards of research in the Antarctic. This book will have armchair travelers, penguin lovers, Antarctic enthusiasts, and science readers rejoicing."

Booklist

"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 Kooyman and writer and fellow Antarctic explorer Mastro offer a detailed explanation of all four journeys. A book that will take you [into] the field with scientists to discover those charismatic and fascinating birds."

PolarJournal (Switzerland), "Our polar book ideas for Christmas"

 "An intriguing addition . . . Journeys with Emperors takes us behind the scenes of pioneering scientific expeditions and then follows up with the scientific results in readable, layman’s language. The bifurcated organization works thanks to the use of a single authoritative narrative voice, a careful arrangement of scientific details, and a sense of wonder that infuses every chapter, whether it’s about hiking over a glacier or the benefits of anaerobic metabolisms. It’s a very enjoyable book to read. It also gives insight into the scientific way of looking at birds and their habitat, and the personal costs and rewards of a life devoted to scientific obsession."

10,000 Birds

“[Kooyman] recounts his tale of one of the most iconic examples of charismatic megafauna in a way that captures both the magnitude of his science and the elegant descriptions and personal anecdotes that transport the reader to the ice (all through the lens of a changing climate). His acts of veritable heroism—raging-river crossings, risky glacial traverses, frequent excursions on figurative and literal thin ice—were simply routine components of his daily scientific procedures.”

Jessica Ulrika Meir, PhD, comparative physiologist and NASA astronaut, from the foreword

“Journeys with Emperors follows a decades-long quest to study the largest, deepest diving, most colorful, and most isolated of the penguins. Readers are literally a part of the research expedition. It is the trials and tribulations, successes and failures of Kooyman and his research team that are at the core of this book. An iconic Antarctic bird makes it all the more engaging, and you walk away with an appreciation of how unique these birds are, as are the people who study them. Everyone will be the better for having read this book, and perhaps, emperor penguins will benefit from such an informed population; I can think of no higher praise.”

Terrie M. Williams, author of "The Odyssey of KP2: An Orphan Seal and a Marine Biologist’s Fight to Save a Species"

“This remarkable book is the most authoritative and readable account of the biology of emperor penguins ever written. Of equal significance is that through example, Kooyman provides insight into the importance of patiently observing and documenting aspects of the natural history of this extraordinary bird, over a period of decades. Collectively, those observations facilitated a stream of original ideas, and the technology needed to test them. As such, Journeys with Emperors models how to successfully conduct long-term research on a wild species in a truly challenging environment.”

“Marine physiologist Kooyman’s captivating memoir, written with one of his research assistants, Mastro, centers on two series of Antarctic journeys, both equally impressive. . . . In addition to his clear and often enthusiastic writing, Kooyman has included many photographs of both the scientists on site and the penguins and seals they lived with over the years. Brew a cup of hot tea and spend some time with these remarkable birds—and the humans that study them.”
