Download or read book The North American Sea Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-11-09 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Birds of the Yukon Territory written by Pamela H. Sinclair and published by UBC Press. This book was released on 2011-11-01 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Yukon is a land of remarkable wilderness, diverse ecosystems, and profound beauty. It is also home to a unique assemblage of birds. As of 2002, 288 bird species have been documented in the Yukon, with 223 occurring regularly. They occupy an amazing range of habitats, from the most barren mountain peaks to lush valley bottom forests, and are an integral part of the cultural heritage of Yukon First Nations people. The vast areas of natural habitat with limited road access can make the study of birds challenging, but are key in defining the nature of birding in the Yukon. Birds of the Yukon Territory is the result of a decade-long project initiated to gather and share what is known about the Yukon's birdlife. Lavishly illustrated with 600 colour photographs and 223 hand-drawn bird illustrations, the book presents a wealth of information on bird distribution, migration and breeding chronology, nesting behaviour, and habitat use, and on conservation concerns. Two hundred and eighty-eight species of birds are documented, including 223 regular species, and 65 casual and accidental species. In compiling this meticulously researched volume, the authors consulted over 166,000 records in a database created by the Canadian Wildlife Service, with information dating back to 1861. S ections on birds in Aboriginal culture and history, and bird names in the Yukon First Nations and Inuvialuit languages, enhance the book, as do the numerous easily interpreted charts and graphs. Destined to become a basic reference work on the avifauna of the North, Birds of the Yukon Territory is a must-have for bird enthusiasts and anyone interested in the natural history of the Yukon and the North.

Download or read book Saving a Million Species written by Lee Hannah and published by Island Press. This book was released on 2012-06-22 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research paper "Extinction Risk from Climate Change" published in the journal Nature in January 2004 created front-page headlines around the world. The notion that climate change could drive more than a million species to extinction captured both the popular imagination and the attention of policy-makers, and provoked an unprecedented round of scientific critique. Saving a Million Species reconsiders the central question of that paper: How many species may perish as a result of climate change and associated threats? Leaders from a range of disciplines synthesize the literature, refine the original estimates, and elaborate the conservation and policy implications. The book: examines the initial extinction risk estimates of the original paper, subsequent critiques, and the media and policy impact of this unique study presents evidence of extinctions from climate change from different time frames in the past explores extinctions documented in the contemporary record sets forth new risk estimates for future climate change considers the conservation and policy implications of the estimates. Saving a Million Species offers a clear explanation of the science behind the headline-grabbing estimates for conservationists, researchers, teachers, students, and policy-makers. It is a critical resource for helping those working to conserve biodiversity take on the rapidly advancing and evolving global stressor of climate change-the most important issue in conservation biology today, and the one for which we are least prepared.

Download or read book The North American Geese written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-08-23 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eight currently recognized species of North American geese are part of a familiar group of birds collectively called waterfowl, all of which are smaller than swans and generally larger than ducks. They include the most popular of our aquatic gamebirds, with several million shot each year by sport hunters. Our two most abundant waterfowl, the Canada goose and snow goose, have populations collectively totaling about 15 million individuals. Like swans, the lifelong pairbonding of geese, their familial care, and prolonged social attachment to their offspring are legendary. Their seasonal migratory flights sometimes span thousands of miles, and the sight of their long, wavering flight formations are as much the symbols of seasonal change as are the spring songs of cardinals or the appearance of autumnal leaf colors. This book describes each species' geographic range and subspecies, its identification traits, weights and measurements, and criteria for its age and sex determination. Ecological and behavioral information includes each species' breeding and wintering habitats, its foods and foraging behavior, its local and long distance movements, and its relationships with other species. Reproductive information includes each species' age of maturity, pair-bond pattern, pair-forming behaviors, usual clutch sizes and incubation periods, brooding behavior, and postbreeding behavior. Mortality sources and rates of egg, young, and adult losses are also summarized, and each species' past and current North American populations are estimated. In addition to a text of nearly 60,000 words, the book includes 8 maps, 21 line drawings, and 28 photographs by the author, as well as more than 700 literature citations.

Download or read book Avian Ecology and Conservation in an Urbanizing World written by John M. Marzluff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most striking and persistent ways humans dominate Earth is by changing land-cover as we settle a region. Much of our ecological understanding about this process comes from studies of birds, yet the existing literature is scattered, mostly decades old, and rarely synthesized or standardized. The twenty-seven contributions authored by leaders in the fields of avian and urban ecology present a unique summary of current research on birds in settled environments ranging from wildlands to exurban, rural to urban. Ecologists, land managers, wildlife managers, evolutionary ecologists, urban planners, landscape architects, and conservation biologists will find our information useful because we address the conservation and evolutionary implications of urban life from an ecological and planning perspective. Graduate students in these fields also will find the volume to be a useful summary and synthesis of current research, extant literature, and prescriptions for future work. All interested in human-driven land-cover changes will benefit from a perusal of this book because we present high altitude photographs of each study area.

Available in PDF, EPUB and Kindle. Book excerpt: “A wonderful book that highlights the globally unique and important boreal forest ecoregion from an avian perspective, with fresh twists. Your ideas about where those migrant and wintering birds in your backyards have come from will be forever changed after you read this.”--Gordon Orians, Professor Emeritus of Biology, University of Washington “One of the planet's most amazing spectacles is the seasonal ebb and flow of migrants from the boreal forests to warmer winter quarters, with stopovers in our neighborhoods in between. This book tells you how connected the world is and what's at risk if we damage any part of it.”--Stuart Pimm, Doris Duke Professor of Conservation Ecology, Duke University, winner of the 2006 Dr. A. H. Heineken Prize “This diverse set of contributions about birds that nest in and migrate to and from North America's boreal forest demonstrates the remarkable interconnectedness of ecosystems across the hemispheres and the incredible responsibility we face to protect them.”--Bridget Stutchbury, York University, author of Silence of the Songbirds and The Private Lives of Birds “The fact that billions of birds breed in North America’s boreal forest is amazing enough, but this assemblage is even more remarkable when understood as playing completely different, major ecological roles across the temperate and tropical Americas during the northern winter. This book definitely will broaden your thinking about ecological connections across the hemisphere and the global-scale phenomenon that crosses our skies twice each year.”--John W. Fitzpatrick, Louis Agassiz Fuertes Director, Cornell Lab of Ornithology
