For these beginning and intermediate enthusiasts, National Geographic Birding Essentials is a must. Comprehensive and authoritative, yet engaging and user-friendly, it teaches readers how to begin and improve their birding... what to look and listen for... and how to make sense of what they see and hear. A unique visual component shows actual field guide pages and how to read them, while another compares the same bird in photography versus artwork and explains how to use both for species identification. National Geographic's quality photography is a major highlight of the book, supplemented by pencil drawings and full-color maps to give the novice and intermediate birder a full range of visual information.Field Ornithologists Jonathan Alderfer and Jon Dunn have crafted a masterful guide, striking just the right balance of practical information and reader-friendly tone. Chapters discuss the pleasures of birding, equipment needed, how to read range maps, birds' physical features, how to identify birds, identification challenges, bird classification and suggested books and journals for building a fine birding library.National Geographic has established a stellar reputation among birders with our blockbuster Field Guide to the Birds of North America. The tradition continues as we serve an entry-level market that continually needs the helpful, up-to-the-minute information found in National Geographic Birding Essentials.

    Not so anymore. All but exterminated, these predators of the not-too-distant past have been reduced to minor players of the modern era. And what of it? Wildlife journalist William Stolzenburg follows in the wake of nature's topmost carnivores, and finds chaos in their absence.From the brazen mobs of deer and marauding raccoons of backyard America to streamsides of Yellowstone National Park crushed by massive herds of elk; from urchin-scoured reefs in the North Pacific to ant-devoured islands in Venezuela, Stolzenburg leads a startling tour through bizarre, impoverished landscapes of pest and plague. For anyone who has seldom given thought to the meat-eating beasts so recently missing from the web of life, here is a world of reason to think again.

    This major work of ecological philosophy startles the senses out of habitual ways of perception.For a thousand generations, human beings viewed themselves as part of the wider community of nature, and they carried on active relationships not only with other people with other animals, plants, and natural objects (including mountains, rivers, winds, and weather patters) that we have only lately come to think of as inanimate. How, then, did humans come to sever their ancient reciprocity with the natural world? What will it take for us to recover a sustaining relation with the breathing earth?In The Spell of the Sensuous David Abram draws on sources as diverse as the philosophy of Merleau-Ponty, Balinese shamanism, Apache storytelling, and his own experience as an accomplished sleight-of-hand of magician to reveal the subtle dependence of human cognition on the natural environment. He explores the character of perception and excavates the sensual foundations of language, which--even at its most abstract--echoes the calls and cries of the earth. On every page of this lyrical work, Abram weaves his arguments with a passion, a precision, and an intellectual daring that recall such writers as Loren Eisleley, Annie Dillard, and Barry Lopez.

    Yet we hardly know them, not even the ones we’re closest to: those that eat our food, share our beds, and live in our homes. Organizing his book alphabetically, Hugh Raffles weaves together brief vignettes, meditations, and extended essays, taking the reader on a mesmerizing exploration of history and science, anthropology and travel, economics, philosophy, and popular culture. Insectopedia shows us how insects have triggered our obsessions, stirred our passions, and beguiled our imaginations.From the Trade Paperback edition.

    Throughout his celebrated career, Schaller has spent more time in Tibet than in any other part of the world, devoting more than thirty years to the wildlife, culture, and landscapes that captured his heart and continue to compel him to protect them.  Tibet Wild is Schaller’s account of three decades of exploration in the most remote stretches of Tibet: the wide, sweeping rangelands of the Chang Tang and the hidden canyons and plunging ravines of the southeastern forests. As engaging as he is enlightening, Schaller illustrates the daily struggles of a field biologist trying to traverse the impenetrable Chang Tang, discover the calving grounds of the chiru or Tibetan antelope, and understand the movements of the enigmatic snow leopard.    As changes in the region accelerated over the years, with more roads, homes, and grazing livestock, Schaller watched the clash between wildlife and people become more common—and more destructive. Thus what began as a purely scientific endeavor became a mission: to work with local communities, regional leaders, and national governments to protect the unique ecological richness and culture of the Tibetan Plateau.    Whether tracking brown bears, penning fables about the tiny pika, or promoting a conservation preserve that spans the borders of four nations, Schaller has pursued his goal with a persistence and good humor that will inform and charm readers.  Tibet Wild is an intimate journey through the changing wilderness of Tibet, guided by the careful gaze and unwavering passion of a life-long naturalist.

    From the most desolate desert to the depths of the jungle, from blistering heat and freezing cold to perpetual darkness and deadly UV, discover how a whole host of creatures have adapted to life in the most extreme conditions. And how they compete with one another to become the largest, the fastest, the most poisonous, or most devious - all in a bid to survive.Planet Earth II includes the first in-depth look at the urban environment, and the surprising range of behaviours occurring right under our noses, as well as some previously untouched island worlds. Filmed with remarkable 5k and infra-red technology, these are the challenges, the confrontations, and the triumphs of some of the most extraordinary creatures in the natural world, told from their perspective.This is our planet, as you have never seen it before.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    This engaging chronicle of how the author and the great horned owl "Bubo" came to know one another over three summers spent in the Maine woods--and of how Bubo eventually grew into an independent hunter--is now available in an edition that has been abridged and revised so as to be more accessible to the general reader.

    All of those organisms are rooted in a single origin, with a common code that underwrites our existence. This paradox - that our biology is indistinct from all life, yet we consider ourselves to be special - lies at the heart of who we are.In this original and entertaining tour of life on Earth, Adam Rutherford explores how many of the things once considered to be exclusively human are not: we are not the only species that communicates, makes tools, utilises fire, or has sex for reasons other than to make new versions of ourselves. Evolution has, however, allowed us to develop our culture to a level of complexity that outstrips any other observed in nature.THE BOOK OF HUMANS tells the story of how we became the creatures we are today, bestowed with the unique ability to investigate what makes us who we are. Illuminated by the latest scientific discoveries, it is a thrilling compendium of what unequivocally fixes us as animals, and reveals how we are extraordinary among them.

    In Europe: A Natural History, world-renowned scientist, explorer, and conservationist Tim Flannery applies the eloquent interdisciplinary approach he used in his ecological histories of Australia and North America to the story of Europe. He begins 100 million years ago, when the continents of Asia, North America, and Africa interacted to create an island archipelago that would later become the Europe we know today. It was on these ancient tropical lands that the first distinctly European organisms evolved. Flannery teaches us about Europe's midwife toad, which has endured since the continent's beginning, while elephants, crocodiles, and giant sharks have come and gone. He explores the monumental changes wrought by the devastating comet strike and shows how rapid atmospheric shifts transformed the European archipelago into a single landmass during the Eocene.As the story moves through millions of years of evolutionary history, Flannery eventually turns to our own species, describing the immense impact humans had on the continent's flora and fauna--within 30,000 years of our arrival in Europe, the woolly rhino, the cave bear, and the giant elk, among others, would disappear completely. The story continues right up to the present, as Flannery describes Europe's leading role in wildlife restoration, and then looks ahead to ponder the continent's future: with advancements in gene editing technology, European scientists are working to recreate some of the continent's lost creatures, such as the great ox of Europe's primeval forests and even the woolly mammoth.Written with Flannery's characteristic combination of elegant prose and scientific expertise, Europe: A Natural History narrates the dramatic natural history and dynamic evolution of one of the most influential places on Earth.

    He wrote vast volumes about animals. He described them, classified them, told us where and how they live and how they develop in the womb or in the egg. He founded a science. It can even be said that he founded science itself.In The Lagoon, acclaimed biologist Armand Marie Leroi recovers Aristotle’s science. He revisits Aristotle’s writings and the places where he worked. He goes to the eastern Aegean island of Lesbos to see the creatures that Aristotle saw, where he saw them. He explores Aristotle’s observations, his deep ideas, his inspired guesses—and the things he got wildly wrong. He shows how Aristotle’s science is deeply intertwined with his philosophical system and reveals that he was not only the first biologist, but also one of the greatest.The Lagoon is both a travelogue and a study of the origins of science. And it shows how a philosopher who lived almost two millennia ago still has so much to teach us today.

    The answers will surprise and delight you as Alexandra Horowitz, a cognitive scientist, explains how dogs perceive their daily worlds, each other, and that other quirky animal, the human.Temple Grandin meets Stephen Pinker in this engaging and informative look at what goes on inside the minds of dogs—from a cognitive scientist with a background at The New Yorker.With more than 52 million pet dogs in America today, it’s clear we are a nation of unabashed dog-lovers. Yet the relationship between dogs and humans remains a fascinating mystery, as no one really knows what goes on in the canine mind. Now, in Inside of a Dog, Alexandra Horowitz fuses her perspectives as both scientist and dog-owner to deliver a fresh look at the world of dogs—as seen from the animal’s point of view. Inspired by her years of living with her own dog, Pumpernickel, who was a constant source of delight and mystery, Horowitz’s mind became filled with questions and ideas. In crisp, clear prose, she draws on her research in the field of dog cognition to give readers a sense of a dog’s perceptual and cognitive abilities—and paints a picture of what the canine experience is like. Horowitz’s own scientific journey, and the insights she uncovered, allowed her to understand her dog better and appreciate her more.Containing up-to-the minute research and providing many moments of dog-behavior recognition, this lively and absorbing book helps dog owners to see their best friend’s behavior in a different, and revealing light, allowing them to understand their pets and enjoy their company even more.
