Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The past decade has seen a huge increase in the interest and attention directed toward sea ducks, the Mergini tribe. This has been inspired, in large part, by the conservation concerns associated with numerical declines in several sea duck species and populations, as well as a growing appreciation for their interesting ecological attributes.

Download or read book Ducks Geese and Swans of North America written by Guy A. Baldassarre and published by JHU Press. This book was released on 2014 with total page 1183 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Birdwatcher s Handbook written by Paul R. Ehrlich and published by Oxford University Press, USA. This book was released on 1994 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: For millions of Americans, birdwatching is nothing less than an obsession. For enthusiasts, the excitement of sighting a rare species, the pleasure of watching a bird in flight, and the satisfaction of being able to spot and identify different birds constitute a burning passion that travels with them wherever they go. The Birdwatcher's Handbook provides a marvelous resource for these dedicated hobbyists, offering a compendium of information about European birds that will be a delight to armchair readers and vacationers alike. In The Birdwatcher's Handbook, authors Paul Ehrlich, David Dobkin, Darryl Wheye, and Stuart Pimm provide in-depth information about British and Northern European birds not found in standard guides. Unlike quick-reference spotter's guides, this volume combines helpful identification aids with thorough descriptions of the birds' behavior and characteristics. Here you can find out where a bird nests, what type of nest it builds, and which partner builds it; how many eggs it lays, what they look like, which parent incubates them, and for how long; how it cares for its young, what it likes to eat, and its foraging habits. This comprehensive volume also provides details about displays, mating, wintering and migration, conservation status, and guides to further reading. For the dedicated birdwatcher on the go (in one of the most popular vacation destinations for Americans), this information will constitute invaluable help for locating and following different birds, and for identifying them by their behavior as well as their appearance. And both bird-loving travelers and homebound enthusiasts will delight in the comprehensive background this book provides on 515 separate species--including 150 short essays on avian natural history. Bird-watchers form a remarkable group, dedicated to following their passion from the backyard to the most distant places. The Birdwatcher's Handbook provides the information they need for both at-a-glance reference in the field and hours of reading pleasure at home--the perfect companion to a trusted identification guide.
