Book Description
Long-term population monitoring is an important tool in our investigations of the role waterbirds play in their environment. This book is international in scope and presents information on species as diverse as the Common Loon, Harlequin Duck, and Semi-Palmated Sandpiper, and habitat in locations ranging from Iceland to Japan. Papers presented in this volume further our understanding of the important role that limnology plays in determining habitat suitability for waterbirds.

Book Description
E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.

Book Description
Coastal Conservation and Management provides the reader with a synthesis of the range and variation of the main coastal formations and includes practical guidance on their management. The book discusses all the main coastal habitats of importance for nature conservation (saltmarsh, shingle, sand dune and seacliff) as well as combinations of these habitats (estuaries and other coastal wetlands). It offers a comprehensive picture of both the soft sedimentary formations and those which are more resilient. While these habitats have all been covered elsewhere in the literature, no single volume gives such a wide-ranging account. An attempt is made throughout to provide the reader with a basic understanding of the importance and range of variation of each habitat and coastal ecosystem. The principal issues are discussed and the key management options identified. Some prescriptive suggestions are made, though for the most part, the reader is left to ponder the issues and their possible solutions.

Book Description
Bird migration is one of the most astonishing feats in the natural world. Millions of birds migrate, often over very large distances, to benefit from seasonal resource surpluses and to avoid predators and competitors. The aim of this study is to survey the phenomena.

Book Description
Presents results of aerial surveys undertaken to determine the principal areas used by nearctic shorebirds and other species of water birds on wintering grounds on the coast of Panama. Additional information is presented on numbers and distributions of these groups of birds on the coast of the Gulf of Panama during migration periods. Surveys of wintering populations were carried out in January 1993, while surveys of populations present during southward and northward migration periods were conducted in October 1991 and February 1988 respectively. Information is also included on aerial survey methodology; the geography, physical oceanography, and climate of Panama; and coastal habitats and their distribution in Panama.

Book Description
New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.
