The apparent decline in numbers among many species of migratory songbirds is a timely subject in conservation biology, particularly for ornithologists, ecologists, and wildlife managers. This book is an attempt to discuss the problem in full scope. It presents an ambitious, comprehensive assessment of the current status of neotropical migratory birds in the U.S., and the methods and strategies used to conserve migrant populations. Each chapter is an essay reviewing and assessing the trend from a different viewpoint, all written by leaders in the fields of ornithology, conservation, and population biology.
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.
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.
Humans have altered and created entirely new environments to which animals have either adapted or been extirpated. Urban environments are one of the most extreme examples of how humans have changed previous habitats. Urban environments present massive challenges for birds living in these spaces and the impacts can be seen on all aspects of their behavior including how they communicate with one another. This book discusses how seabirds and songbirds have adapted for life in urban areas, how it has impacted their migratory behavior, and also examines the ecology and conservation of these two species.
Foreword by Jonathan Franzen Original poem by Margaret Atwood With species ranging from tiny iridescent-green hummingbirds to giant, gangly flightless rheas, the Americas feature an astonishing array of birds that rely upon the region's tremendous diversity of habitats. That reliance may be very localized or it may reach across continents: Swainson's Thrushes travel from South America all the way to Alaska, while certain grebes spend their entire lives on a single lake. Treasured songbirds feed at northern backyard feeders yet often arrive from points far to the south. The American Bird Conservancy (ABC) works across the Americas with a goal to have birds routinely prioritized in all land-use and policy decision-making. Bringing Back the Birds showcases these efforts, alongside the stunning photography of Owen Deutsch and eloquent essays from renowned experts in the field: Peter P. Marra, Smithsonian Migratory Bird Center; researchers Kimberly and Kenn Kaufman; John W. Fitzpatrick, Cornell Lab of Ornithology; and Mike Parr, EJ Williams, and Clare Nielsenof ABC.

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.
Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight. Nature’s great migrations have captivated countless spectators, none more so than premier ecologist David S. Wilcove. In No Way Home, his awe is palpable—as are the growing threats to migratory animals. We may be witnessing a dying phenomenon among many species. Migration has always been arduous, but today’s travelers face unprecedented dangers. Skyscrapers and cell towers lure birds and bats to untimely deaths, fences and farms block herds of antelope, salmon are caught en route between ocean and river, breeding and wintering grounds are paved over or plowed, and global warming disrupts the synchronized schedules of predators and prey. The result is a dramatic decline in the number of migrants. Wilcove guides us on their treacherous journeys, describing the barriers to migration and exploring what compels animals to keep on trekking. He also brings to life the adventures of scientists who study migrants. Often as bold as their subjects, researchers speed wildly along deserted roads to track birds soaring overhead, explore glaciers in search of frozen locusts, and outfit dragonflies with transmitters weighing less than one one-hundredth of an ounce. Scientific discoveries and advanced technologies are helping us to understand migrations better, but alone, they won’t stop sea turtles and songbirds from going the way of the bison or passenger pigeon. What’s required is the commitment and cooperation of the far-flung countries migrants cross—long before extinction is a threat. As Wilcove writes, “protecting the abundance of migration is key to protecting the glory of migration.” No Way Home offers powerful inspiration to preserve those glorious journeys.
