Accompanying range maps; overhead flight silhouettes; and sections on bird-watching, accidental species, and endangered birds make the National Audubon Society's Field Guide to North American Birds the most comprehensive available.Note: the Eastern Edition generally covers states east of the Rocky Mountains, while the Western Edition covers the Rocky Mountain range and all the states to the west of it.

    There they began a strenuous and thrilling hundred-day field trip around the edge of the continent. Part travelogue, part epic natural adventure, their richly illustrated record is "the superlatively good product of ideal circumstances" (Chicago Sunday Tribune).

    The largest of them, the Siberian tiger, is today almost entirely confined to the little-populated Russian Far East, a region that may offer the species' best hope for survival. But the implosion of the Soviet Union intensified poaching and habitat depredation, prompting a group of Russian researchers and U.S. wildlife biologists led by Maurice Hornocker to join forces to stave off extinction.Peter Matthiessen brings to the Siberian tiger the deep knowledge of and feeling for the natural world that have made classics of his previous books. Accompanying researchers into the field, he allows the reader to participate vicariously in the battle for the tiger's future. Along the way, he tells how the species evolved and evokes its crucial, often totemic role in human cultures and mythologies. He has made of the tiger's dilemma a drama-underscored by Hornocker's one-of-a-kind photographs-that conveys powerfully what a loss to our collective imagination the disappearance of these great cats would be.

    These torchlight adventures have since inspired a generation of scientists, and his research is still considered useful today. In The Secret Life of Wombats, James Woodford pursues Nicholson's story and embarks on his own journey to uncover the true nature of our most intriguing marsupial."Woodford has done the research, he has read widely, spoken with the major wombat pundits and with the lay observers. He has travelled to gain direct experience of all species...I know more about wombats than I did, and retain some stark images which I hope never to lose." - Sunday Age.

    He has observed more than six thousand species during travels that have taken him to every continent. He founded the largest company in the world specializing in birding tours and one of the most respected ones in ecotourism. Emanuel has received some of birding’s highest honors, including the Roger Tory Peterson Award from the American Birding Association and the Arthur A. Allen Award from the Cornell Laboratory of Ornithology. He also started the first birding camps for young people, which he considers one of his greatest achievements.In One More Warbler, Emanuel recalls a lifetime of birding adventures—from his childhood sighting of a male Cardinal that ignited his passion for birds to a once-in-a-lifetime journey to Asia to observe all eight species of cranes of that continent. He tells fascinating stories of meeting his mentors who taught him about birds, nature, and conservation, and later, his close circle of friends—Ted Parker, Peter Matthiessen, George Plimpton, Roger Tory Peterson, and others—who he frequently birded and traveled with around the world. Emanuel writes about the sighting of an Eskimo Curlew, thought to be extinct, on Galveston Island; setting an all-time national record during the annual Audubon Christmas Bird Count; attempting to see the Imperial Woodpecker in northwestern Mexico; and birding on the far-flung island of Attu on the Aleutian chain. Over the years, Emanuel became a dedicated mentor himself, teaching hundreds of young people the joys and enrichment of birding. “Birds changed my life,” says Emanuel, and his stories make clear how a deep connection to the natural world can change everyone’s life.

    What is going on inside the head of a nightingale as it sings, and how does its brain improvise? How do desert birds detect rain hundreds of kilometers away? How do birds navigate by using an innate magnetic compass?Tracing the history of how our knowledge about birds has grown, particularly through advances in technology over the past fifty years, Bird Sense tells captivating stories about how birds interact with one another and their environment. More advanced testing methods have debunked previously held beliefs, such as female starlings selecting mates based on how symmetrical the male's plumage markings are. (Whereas females can discern the difference between symmetrical and asymmetrical markings, they are not very good at detecting small differences among symmetrically marked males!)Never before has there been a popular book about how intricately bird behavior is shaped by birds' senses. A lifetime spent studying birds has provided Tim Birkhead with a wealth of fieldwork experiences, insights, and a unique understanding of birds, all firmly grounded in science. No one who reads Bird Sense can fail to be dazzled by it.

    In the United States we sometimes call them buzzards; in parts of Mexico the name is aura cabecirroja, in Uruguay jote cabeza colorada, and in Ecuador gallinazo aura. A huge bird, the turkey vulture is a familiar sight from culture to culture, in both hemispheres. But despite being ubiquitous and recognizable, the turkey vulture has never had a book of literary nonfiction devoted to it—until Vulture. Floating on six-foot wings, turkey vultures use their keen senses of smell and sight to locate carrion. Unlike their cousin the black vulture, turkey vultures do not kill weak or dying animals; instead, they cleanse, purify, and renew the environment by clearing it of decaying carcasses, thus slowing the spread of such dangerous pathogens as anthrax, rabies, and botulism. The beauty, grace, and important role of these birds in the ecosystem notwithstanding, turkey vultures are maligned and underappreciated; they have been accused of spreading disease and killing livestock, neither of which has ever been substantiated. Although turkey vultures are protected under the Migratory Bird Treaty Act, which makes harming them a federal offense, the birds still face persecution. They’ve been killed because of their looks, their odor, and their presence in proximity to humans. Even the federal government occasionally sanctions “roost dispersals,” which involve the harassment and sometimes the murder of communally roosting vultures during the cold winter months. Vulture follows a year in the life of a typical North American turkey vulture. By incorporating information from scientific papers and articles, as well as interviews with world-renowned raptor and vulture experts, author Katie Fallon examines all aspects of the bird’s natural history: breeding, incubating eggs, raising chicks, migrating, and roosting. After reading this book you will never look at a vulture in the same way again.

    Through scrupulous research and vivid first-person reporting, The First Human reveals the perils and the promises of fossil hunting on a grand competitive scale.

    These winged creaturesfrom exotic parrots to everyday sparrows, and endangered penguins to woody owlsare captured with Zuckerman's painstaking perspective against a stark white background to reveal the vivid colors, textures, and personalities of each subject in extraordinary and exquisite detail. The ultimate art book for ornithologists and nature enthusiasts alike, Bird is a volume of sublime beauty.

    In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring. This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult readers alike, this book follows on the author's previous bestseller, What If the Moon Didn't Exist?, with completely new scenarios backed by the latest astronomical research.

    Driven by moral imperatives and pressing environmental realities, Bekoff offers six compelling reasons for changing the way we treat animals — whether they’re in factory farms, labs, circuses, or our vanishing wilderness. The result is a well-researched, informative guide that will change animal and human lives for the better.

    Using the typical contents of a child's school backpack (defined as water, food, clothing, paper, plastic, metals, electronics), this book explores those stages in detail, including lots of ways to reduce, reuse or recycle waste along the way. Children will gain new insight into the routine decisions they make about their own consuming and trashing or recycling practices. For example: How long does it take for a cotton T-shirt to decompose in a landfill? Can a bike helmet be made from recyclable materials? Which is better for the Earth, wrapping a sandwich in aluminum foil or plastic? By learning to use critical thinking skills to make informed choices, children will feel empowered by the important, constructive role they can play in the future health of the planet. Author Erica Fyvie has found a way to use everyday objects to speak directly to children's curiosity and their desire to make a difference. With infographics, short subsections, sidebars and charts, the information presented is engaging and accessible. Playful illustrations by award-winning illustrator Bill Slavin help make complex subjects easier to understand, while keeping the tone friendly. From energy to climate, innovations to sustainability, this all-encompassing look at a timely topic is the perfect go-to resource for elementary science and social studies classrooms. Includes a glossary, resources, bibliography and index.

    Evolutionists have never been able to completely explain why birdsong is so inventive and why many species devote so many hours to singing. The standard explanations of defending territories and attracting mates don't begin to account for the variety and energy that the commonest birds exhibit. Is it possible that birds sing because they like to? This seemingly naive explanation is starting to look more and more like the truth. Why Birds Sing is a lyric exploration of birdsong that blends the latest scientific research with a deep understanding of musical beauty and form. Drawing on conversations with neuroscientists, ecologists, and composers, it is the first book to investigate the elusive question of why birds sing and what their song means to both avian and human ears. Whether playing his clarinet with the whitecrested laughing thrush in Pittsburgh, or jamming in the Australian winter breeding grounds of the Albert's lyrebird, Rothenberg immerses himself in the heart and soul of birdsong. He approaches the subject as a naturalist, philosopher, musician, and investigator. An intimate look at the mostlovely of natural phenomena, Why Birds Sing is a beautifully written exploration of a phenomenon that's at once familiar and profoundly alien.

    Few people know bears as intimately as Else Poulsen. She has raised bears, comforted bears, taught bears, learned from bears, had bears communicate their needs to her, and nursed bears back to health. This remarkable book reveals the many insights about bears and their lives that she has gained through her work with them. In the eighties, Poulsen became a zookeeper in Calgary, where she rehabilitated bears in crisis. She has shared in the joy of a polar bear discovering soil under her paws for the first time in twenty years, felt the pride of a cub learning to crack nuts with her molars, and grieved at the horror of captivity for Asian black bears in China.Smiling Bears provides an enlightening and moving portrait of bears in all their richness and complexity and of Poulsen's exhilarating work with them. Also available in paperback.

    But sometimes, to our utter amazement and everlasting gratitude, animals literally save our lives, and this heartwarming book collects over 50 real-life stories of animals rescuing people, in which the actions of animals have meant the difference between life and death. Today, scientists vigorously debate questions regarding the sentience, intelligence, and emotions of animals. In particular, they want to know whether animals share with humans the highest emotions of empathy, compassion, and altruism. This book also poses these questions for readers to consider, and using current research on animal minds and emotions, it examines these extreme life-saving situations for possible evidence. Where appropriate, skepticism and doubt surrounding particular stories is included, but gathered together, these anecdotes make a compelling case for the presence of altruism in animals. Thus, this book provides dramatic, thrilling, and moving stories that convey a hopeful message about our world. But these stories also provide startling evidence of the mental and emotional capacities of animals, those being we share the world with.
