Book Description
"Two eider populations breed in the western Canadian Arctic and winter in the Bering Sea: the Pacific subspecies of the Common Eider Somateria mollissima v-nigra and the western Arctic population of the King Eider S. spectabilis. Both eiders are harvested primarily in the spring by the Aboriginal people of northern communities and to a small extent in faIl by sport hunters. Some eggs of the colonially nesting Common Eider are also taken. Compared with other harvested waterfowl, there are few available data on even the most basic aspects of the biology of these two eider populations, induding their status and nesting distribution"--Introd.

Book Description
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.

Book Description
A monograph of the Common Eider, a large and familiar duck with a long and fascinating cultural history. A common sight around the more northerly shores of the British Isles, the Common Eider is the largest duck in the northern hemisphere. The eider is particularly well adapted to cold-water environments; the insulating properties of eider down are iconic. The species is taxonomically interesting, with a range of well-marked subspecies reflecting the patterns of ice coverage during ancient glaciations, and these ducks have also provided the focus for a number of important behavioural studies, especially on feeding ecology and energy budgets. Eiders have a long association with humans, and have deep cultural significance in many societies. However, modern lifestyles are exposing these ducks to a wide range of new pressures. This monograph provides a comprehensive portrait of the Common Eider; authors Chris Waltho and John Coulson bring together an extensive and diverse international literature, with sections on taxonomy, habitats, breeding biology, population dynamics, diet and foraging, dispersal and migration, and conservation.

Book Description
The best-selling and authoritative reference book on waterfowl has been fully revised and updated by one of the world’s most respected waterfowl biologists. Honorable Mention for the PROSE Award for Excellence, Multivolume/Science of the Association of American Publishers 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 stunning 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. This edition of Ducks, Geese, and Swans consists of two volumes, printed in full color, and packaged in a slipcase, along with a CD containing references and additional maps.

Book Description
In spite of the harsh conditions that characterize the Arctic, it is a surprisingly fragile ecosystem. The exploration for oil in the Arctic over the past 30 years has had profound effects on the plants and animals that inhabit this frozen clime. The Natural History of an Arctic Oil Field synthesizes decades of research on these myriad impacts. Specialists with years of field experience have contributed to this volume to create the first widely available synopsis of the ecology and wildlife biology of animals and plants living in close association with an actively producing oil field. - First widely available synthesis of arctic oil field ecology and wildlife biology - Concise yet readable treatment of a diverse polar ecosystem - Useful for land managers, policy makers as well as ecologists, and population biologists - Chapters authored by recognized authorities and contributions are peer-reviewed for accuracy and scientific rigor - Illustrations attractively designed to enhance comprehension

Book Description
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.
