Book Description
Singing-ground surveys of the American woodcock indicate that breeding populations have increased gradually over the past 7 years while production, as indicated by wing-collection surveys, has remained relatively stable. The woodcock harvest, meanwhile, has probably more than doubled during the past decade. This suggests that while woodcock are probably becoming more important to North American sportsmen, hunting mortality is still relatively unimportant.
Contribution Toward a Bibliography on Brant

Book Description
This bibliography was prepared to facilitate collection of information useful in management or in planning additional studies on the Clarence Rhode National Wildlife Range on the Yukon-Kuskokwim Delta of Alaska which contain the most important nesting areas of the black brant (Branta bernicla nigricans). Emphasis was placed on locating references to the Pacific black brant, but references to the Atlantic brant (Branta bernicla horta) have been included.

Book Description
Each fall and spring, millions of birds travel the Pacific Flyway, the westernmost of the four major North American bird migration routes. The landscapes they cross vary from wetlands to farmland to concrete, inhabited not only by wildlife but also by farmers, suburban families, and major cities. In the twentieth century, farmers used the wetlands to irrigate their crops, transforming the landscape and putting migratory birds at risk. The U.S. Fish and Wildlife Service responded by establishing a series of refuges that stretched from northern Washington to southern California. What emerged from these efforts was a hybrid environment, where the distinctions between irrigated farms and wildlife refuges blurred. Management of the refuges was fraught with conflicting priorities and practices. Farmers and refuge managers harassed birds with shotguns and flares to keep them off private lands, and government pilots took to the air, dropping hand grenades among flocks of geese and herding the startled birds into nearby refuges. Such actions masked the growing connections between refuges and the land around them. Seeking Refuge examines the development and management of refuges in the wintering range of migratory birds along the Pacific Flyway. Although this is a history of efforts to conserve migratory birds, the story Robert Wilson tells has considerable salience today. Many of the key places migratory birds use — the Klamath Basin, California’s Central Valley, the Salton Sea — are sites of recent contentious debates over water use. Migratory birds connect and depend on these landscapes, and farmers face pressure as water is reallocated from irrigation to other purposes. In a time when global warming promises to compound the stresses on water and migratory species, Seeking Refuge demonstrates the need to foster landscapes where both wildlife and people can thrive.

Pages : 1183
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.

Book Description
The migratory waterbirds of the Pacific Flyway convert food, air, and water into a mileage plan that has few equals in the animal world. Set against a backdrop of stunning images from more than 120 internationally acclaimed photographers, this book shares the amazing stories of these migrants--a cast of characters that includes shorebirds, seabirds, and waterfowl. Stretching from the Arctic regions of northeastern Russia, Alaska, and western Canada and along the Pacific coastlines of North, Central, and South America, the Pacific Flyway traverses some of our planet's greatest climatic and topographic extremes. Defined by water, the flyway encompasses a sweeping expanse of coastal and offshore marine ecosystems and an inland archipelago of freshwater wetlands. Hemispheric in scope, this integrated network of ecosystems is linked by its moving parts--the millions of migratory birds whose lives depend on this 10,000-mile (16,000-km) corridor as they travel between their breeding and overwintering grounds. With their ocean- and continent-spanning travels, waterbirds are our sentinels in a changing world--each of their journeys revealing the fraying edges of the web of life that sustains us all. Pacific Flyway perfectly blends amazing photography, science writing, and storytelling to illuminate the profound challenges faced by migratory birds and to inspire a longterm commitment to global conservation efforts.
