Numbers of nests were down from 2002 for geese and eiders. Depredation rates were high resulting in substantial nest destruction and egg loss. Predation by arctic foxes contributed significantly to poor production."--Page [1].

Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis The Influence of Fall Storms on Nest Densities of Geese and Eiders on the Yukon-Kuskokwim Delta of Alaska by : Sarah Therese Saalfeld
Download or read book The Influence of Fall Storms on Nest Densities of Geese and Eiders on the Yukon-Kuskokwim Delta of Alaska written by Sarah Therese Saalfeld and published by . This book was released on 2015 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final project report summarizes the methods and findings from the investigation of the impacts of fall storms on waterbird nest densities on the outer coast of the Yukon Kuskokwim Delta of Alaska. The purpose is to understand the potential effects of climate changes, such as sea level rises and increased storm frequency and intensity to waterbird populations and breeding habitat. The authors investigated the short-term and long-term effects of storm surges to geese and eider species that commonly breed in the delta. Those species studies in this report are cackling goose, emperor goose, black brant, greater white-fronted goose, spectacles eider, common eider. The authors compared nest densities in relation to magnitude of storms that occurred in the preceding fall between 2000 and 2013, and modeled nest densities using random forests in relation to the time-integrated flood index for modeled storms and for other environmental covariates.
Book Synopsis Role of Wetlands and Endogenous Factors on Incubation Behavior of Nesting Spectacled Eiders on the Yukon-Kuskokwim Delta, Alaska by : William Todd O'Connell

This book was released on 2001 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Patterns of nest attendance in ducks vary with endogenous and environmental factors. We examined variation in nest attendance of spectacled eiders on the Yukon-Kuskokwim Delta, Alaska, during 1997-1998. We also examined spatial and temporal variation in wetland characteristics and potential foods available to nesting spectacled eiders. Time spent foraging was greater when spectacled eiders traveled farther to feed, and nest attendance was lower when food was more abundant, suggesting that females made tradeoffs between foraging and energetic requirements of nesting in response to food abundance and wetland conditions. Wetlands were dynamic, and food abundance varied with pond depth and total dissolved solids. Spectacled eiders responded in complex ways to a suite of physiological and environmental variables, and employed an overall behavioral strategy that optimized foraging behavior in response to food abundance, while minimizing risk of depleting nutrient reserves sufficiently to force nest abandonment or increase the risk of female mortality"--Leaf iii.
