Book Description
Presents a synthesis on the ecology, status, and conservation of marine and shoreline birds of the Queen Charlotte Islands, compiling papers on various disciplines to provide a review of what is currently known about the Islands' marine biology, with a particular emphasis on birds. The papers are presented in five sections: the physical and biological environment and prey organisms, including physical oceanography, zooplankton distribution and availability, and marine fishes as prey; nesting populations of marine birds and distribution of birds at sea; distribution and association of marine waterfowl, including papers on the distribution and ecology of Branta bernicla; seasonality and nesting of shorebirds; and introduced predators and toxic chemicals.

Book Description
Proceedings of a symposium that reviewed what is currently known about the west coast of Vancouver Island, with particular emphasis on birds. Papers cover the physical and biological environment, including the physical oceanography of the west coast of Vancouver Island; the population and breeding ecology of marine and shoreline birds; the distribution of marine and shoreline birds at sea, including bird populations and their habitats offshore, in fjords, in estuaries and over eelgrass bed; and oil pollution and conservation of marine and shoreline birds, including the effects of oil from the NESTUCCA oil spill on marine birds, the effects of environmental disturbances, and conservation measures necessary to protect marine birds.

Book Description
This report was compiled & edited by the interagency Marbled Murrelet Conservation Assessment Core Team. The 37 chapters cover both original studies & literature reviews of many aspects of the species' biology, ecology, & conservation needs. It includes new information on the forest habitat used for nesting, marine distribution, & demographic analyses; & describes past & potential effects of humans on the species habitats. Future research needs & possible management strategies for both marine & forest habitats are suggested. Charts & tables.

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.

Book Description
Describes and maps the North American oceanic and coastal waters, classifying them into 24 marine ecoregions, according to oceanographic features and geographically distinct assemblages of species. Descriptive profiles of the ecoregions describe their key features, in terms of physical, oceanographic, and biological characteristics, as well as human impacts. The book is intended to provide a framework for collecting and organizing information on these regions, and to encourage a sense of joint responsibility and a collaborative strategic approach to dealing with the challenges of conserving the regions' shared oceans.

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
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.
