Behaviour and Ecology of Sea Ducks


Book Description

Contains papers presented at a conference on sea ducks, a group of waterfowl exhibiting dramatic ornate plumages and life history strategies that are more akin to sea birds than to other species of ducks. Topics of the papers include: behaviour of harlequin ducks and scoters; productivity of breeding harlequin ducks; time budgets of surf scoter broods; habitat associations of nesting spectacled eiders; periodic non-breeding of Steller's eiders; philopatry of moulting harlequin ducks; foraging strategies and habitat use; distribution of scoters and eiders in the St. Lawrence estuary; and the eastern population of Barrow's goldeneye. Appendices include abstracts of nine other papers.




Ecology and Conservation of North American Sea Ducks


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. Reflec




The North American Sea Ducks


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.




Ducks, Geese, and Swans of North America


Book Description

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.

Aquatic Birds in the Trophic Web of Lakes


Book Description

Birds are an integral part of most freshwater ecosystems (lakes, rivers, wetlands) but their role in the trophic dynamics of these water bodies has often been overlooked. As a conspicuous part of the biota of water bodies, aquatic birds are indicators of their trophic state both in terms of species composition (quality) as well as occupancy and breeding (quantity). Birds may also influence the trophic state of a water body by importing nutrients (.e.g. resident or migrating birds feeding on adjacent watersheds or the sea). Because of anthropogenic activities, predation or their mobility, birds may not utilize otherwise suitable aquatic habitat. These factors complicate the relationship between aquatic bird production and the trophic status of habitats. As a consequence, the role of aquatic birds in freshwater ecosystems has usually been ignored. This volume contains a wide range of papers selected from those presented at the symposium and reviewed.

The Common Eider


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.
