Book Description
For over one hundred years, ornithologists and amateur birders have jointly campaigned for the conservation of bird species, documenting not only birds’ beauty and extraordinary diversity, but also their importance to ecosystems worldwide. But while these avian enthusiasts have noted that birds eat fruit, carrion, and pests; spread seed and fertilizer; and pollinate plants, among other services, they have rarely asked what birds are worth in economic terms. In Why Birds Matter, an international collection of ornithologists, botanists, ecologists, conservation biologists, and environmental economists seeks to quantify avian ecosystem services—the myriad benefits that birds provide to humans. The first book to approach ecosystem services from an ornithological perspective, Why Birds Matter asks what economic value we can ascribe to those services, if any, and how this value should inform conservation. Chapters explore the role of birds in such important ecological dynamics as scavenging, nutrient cycling, food chains, and plant-animal interactions—all seen through the lens of human well-being—to show that quantifying avian ecosystem services is crucial when formulating contemporary conservation strategies. Both elucidating challenges and providing examples of specific ecosystem valuations and guidance for calculation, the contributors propose that in order to advance avian conservation, we need to appeal not only to hearts and minds, but also to wallets.

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.

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.

Book Description
In the first decades of the twentieth century, fish in the Great Lakes and Puget Sound, seals in the North Pacific, and birds across North America faced a common threat: over harvesting that threatened extinction for many species. Progressive era conservationists saw a need for government intervention to protect threatened animals. And because so many species migrated across international political boundaries, their protectors saw the necessity of international conservation agreements. In The Dawn of Conservation Diplomacy, Kurkpatrick Dorsey examines the first three comprehensive wildlife conservation treaties in history, all between the United States and Canada: the Inland Fisheries Treaty of 1908, the North Pacific Fur Seal Convention of 1911, and the Migratory Bird Treaty of 1916. In his highly readable text, Dorsey argues that successful conservation treaties came only after conservationists learned to marshal scientific evidence, public sentiment, and economic incentives in their campaigns for protective legislation. The first treaty, intended to rescue the overfished boundary waters, failed to gain the necessary support and never became law. Despite scientific evidence of the need for conservation, politicians, and the general public were unable to counter the vocal opposition of fishermen across the continent. A few years later, conservationists successfully rallied popular sympathy for fur seals threatened with slaughter and the North Pacific Fur Seal Convention was adopted. By the time of the Migratory Bird Treaty of 1916, the importance of aesthetic appeal was clear: North American citizens were joining chapters of the Audubon Society in efforts to protect beautiful songbirds. Conservationists also presented economic evidence to support their efforts as they argued that threatened bird species provided invaluable service to farmers. Dorsey recounts the story of each of these early treaties, examining the scientific research that provided the basis for each effort, acknowledging the complexity of the issues, and presenting the personalities behind the politics. He argues that these decades-old treaties both directly affect us today and offer lessons for future conservation efforts.

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.

Book Description
P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.
