Ducks, Geese, and Swans of North America has been hailed as a classic since the first edition was published in 1942. A must-have for professional biologists, birders, waterfowl hunters, decoy collectors, and wildlife managers, this fully revised and updated edition provides definitive information on the continent's forty-six species. Maps of both winter and breeding ranges are presented with images by top waterfowl photographers and the acclaimed original artwork of Robert W. (Bob) Hines. Originally authored by F. H. Kortright and later revised by Frank Bellrose, this latest edition, which has been meticulously updated by renowned waterfowl biologist Guy Baldassarre, continues the legacy of esteemed authors. Each species account contains in-depth sections on: - identification - distribution - migration behavior - habitat - population status - breeding biology - rearing of young - recruitment and survival - food habits and feeding ecology - molts and plumages - conservation and management To facilitate identification, the species accounts also include detailed illustrations of wings. An appendix contains comparative illustrations of ducklings, goslings, and cygnets. Guy Baldassarre has hit the target. His remake of the Kortright/Bellrose classic provides good biological descriptions, wonderful photographs and illustrations, and easy-to-understand information about waterfowl. I would encourage every hunter and enthusiast to have these books as an educational guide to waterfowl and their needs.--H. Dale Hall, CEO, Ducks Unlimited, Inc. When, as an eleven-year-old in 1942, I read F. H. Kortright's first edition of this book, it altered the trajectory of my life. Every subsequent edition, including this latest update by Guy Baldassarre, has improved the landmark reference. I can't imagine that anyone interested in waterfowl or wetlands can live without this indispensable book.--Paul A. Johnsgard, University of Nebraska-Lincoln Creating a brand-new version of such a timeless and previously revised classic is a risky venture indeed, but nobody could be better suited for this monumental task than Guy Baldassarre. He has created a stunning new classic, at once magnificent in its visual appeal and truly comprehensive in its scientific breadth and depth. Hats off to Guy for dedicating himself to this project with such obvious passion, patience, and skill. This book absolutely belongs on the shelf or coffee table of anyone who has ever marveled at waterfowl, whether through their binoculars or from inside the duck blind.--John W. Fitzpatrick, Cornell Laboratory of Ornithology Guy Baldassarre was a professor of wildlife ecology at the State University of New York College of Environmental Science and Forestry in Syracuse until his death in 2012. He is the coauthor of the textbook, Waterfowl Ecology and Management.

The 21 species of sea ducks are one of the larger subgroups (Tribe Mergini) of the waterfowl family Anatidae, and the 16 species (one historically extinct) that are native to North America represent the largest number to be found on any continent, and also the largest number of endemic sea duck species native to any continent. Although generally not important as game birds, the sea ducks include some economically important birds such as the eiders, the basis for the Arctic eiderdown industry and a historically important food source for some Native American cultures. They also include what is probably the most northerly breeding species of all waterfowl and an icon of Arctic bird life, the long-tailed duck. The sea ducks also include species having some of the most complex and diverse pair-forming postural and acoustic displays of all waterfowl (goldeneyes and bufflehead), and some of the deepest diving species of all waterfowl (scoters and long-tailed duck). Sea ducks are highly prone to population disasters caused by oil spills and other water contaminants and, like other seabirds, are among the first bird groups that are being affected by current global warming trends in polar regions. This book is an effort to summarize succinctly our current knowledge of sea duck biology and to provide a convenient survey of the vast technical literature on the group, with over 900 literature references. It also includes 90,000 words of text (more than 40 percent of which is new), 15 updated range maps, 11 black & white and 20 color photographs, over 30 ink drawings, and nearly 150 sketches. Lastly, the North American sea ducks include the now extinct Labrador duck, the only northern hemisphere waterfowl species to have gone extinct in modern times. I have gratefully reprinted a Labrador duck watercolor by Sir Peter Scott. Considering recent population crashes in other sea ducks, such as the Steller’s eider and spectacled eider, it should also offer a sobering reminder of the fragility of our natural world and its inhabitants, including us.

In this newly revised and expanded edition of the award-winning International Environmental Policy, Lynton Keith Caldwell updates his comprehensive survey of the global international movement for protection of the environment. Serving as a history of international cooperation on environmental issues, this book focuses primarily on the development of international agreements and institutional arrangements--both governmental and nongovernmental--along with the impact of science, technology, trade, and communication on environmental policy. With implications for multinational commerce, population policy, agriculture, energy issues, biological and cultural diversity, transnational equity, ideology, and education, this book takes a broad view of the policy outcomes of what may be the most important social movement of the 20th century, and addresses the events and politics that have significantly affected the movement over the last twenty years and will continue to affect it into the next century.
