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
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 foremost experts on the North American Model of Wildlife Conservation come together to discuss its role in the rescue, recovery, and future of our wildlife resources. At the end of the nineteenth century, North America suffered a catastrophic loss of wildlife driven by unbridled resource extraction, market hunting, and unrelenting subsistence killing. This crisis led powerful political forces in the United States and Canada to collaborate in the hopes of reversing the process, not merely halting the extinctions but returning wildlife to abundance. While there was great understanding of how to manage wildlife in Europe, where wildlife management was an old, mature profession, Continental methods depended on social values often unacceptable to North Americans. Even Canada, a loyal colony of England, abandoned wildlife management as practiced in the mother country and joined forces with like-minded Americans to develop a revolutionary system of wildlife conservation. In time, and surviving the close scrutiny and hard ongoing debate of open, democratic societies, this series of conservation practices became known as the North American Model of Wildlife Conservation. In this book, editors Shane P. Mahoney and Valerius Geist, both leading authorities on the North American Model, bring together their expert colleagues to provide a comprehensive overview of the origins, achievements, and shortcomings of this highly successful conservation approach. This volume • reviews the emergence of conservation in late nineteenth–early twentieth century North America • provides detailed explorations of the Model's institutions, principles, laws, and policies • places the Model within ecological, cultural, and socioeconomic contexts • describes the many economic, social, and cultural benefits of wildlife restoration and management • addresses the Model's challenges and limitations while pointing to emerging opportunities for increasing inclusivity and optimizing implementation Studying the North American experience offers insight into how institutionalizing policies and laws while incentivizing citizen engagement can result in a resilient framework for conservation. Written for wildlife professionals, researchers, and students, this book explores the factors that helped fashion an enduring conservation system, one that has not only rescued, recovered, and sustainably utilized wildlife for over a century, but that has also advanced a significant economic driver and a greater scientific understanding of wildlife ecology.

Book Description
Golden-winged Warblers (Vermivora chrysoptera) are migratory songbirds that breed in temperate North America, primarily in the Great Lakes region with remnant populations throughout the Appalachian Mountains, and winter in Central and northern South America. Their breeding range has contracted dramatically in the Appalachian Mountains and many populations have dramatically declined, likely due to habitat loss, competition and interbreeding with Blue-winged Warblers (Vermivora pinus), andglobal climate change.. As a result of population declines in much of the eastern portion of their breeding range, Golden-winged Warblers are listed as endangered or threatened in 10 U.S. states and in Canada and have been petitioned for protection under the U.S. Endangered Species Act. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series compiles extensive, current research on Golden-winged Warblers and summarizes what is known and identifies many remaining unknowns, providing a wealth of peer-reviewed science on which future research and listing decisions can be based.

Book Description
Whether we live in cities, in the suburbs, or in the country, birds are ubiquitous features of daily life, so much so that we often take them for granted. But even the casual observer is aware that birds don’t fill our skies in the number they once did. That awareness has spawned conservation action that has led to notable successes, including the recovery of some of the nation’s most emblematic species, such as the Bald Eagle, Brown Pelican, Whooping Crane, and Peregrine Falcon. Despite this, a third of all American bird species are in trouble—in many cases, they’re in imminent danger of extinction. The most authoritative account ever published of the threats these species face, The American Bird Conservancy Guide to Bird Conservation will be the definitive book on the subject. The Guide presents for the first time anywhere a classification system and threat analysis for bird habitats in the United States, the most thorough and scientifically credible assessment of threats to birds published to date, as well as a new list of birds of conservation concern. Filled with beautiful color illustrations and original range maps, the Guide is a timely, important, and inspiring reference for birders and anyone else interested in conserving North America’s avian fauna. But this book is far more than another shout of crisis. The Guide also lays out a concrete and achievable plan of long-term action to safeguard our country’s rich bird life. Ultimately, it is an argument for hope. Whether you spend your early weekend mornings crouched in silence with binoculars in hand, hoping to check another species off your list, or you’ve never given much thought to bird conservation, you’ll appreciate the visual power and intellectual scope of these pages.
