Mowat's account of the summer he lived in the frozen tundra alone—studying the wolf population and developing a deep affection for the wolves (who were of no threat to caribou or man)—is today celebrated as a classic of nature writing, at once a tale of remarkable adventures and indelible record of myths and magic of wolves.

    It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

    Illustrated with hundreds of his original photographs, Tracking & the Art of Seeing provides complete information on the behavior and habitat of over 50 animal species and shows you how to identify animals by their tracks, tail patterns, droppings, dens, scratches and other signs.

    By some estimates, we may already have lost almost half of the songbirds that filled the skies only forty years ago. Renowned biologist Bridget Stutchbury convincingly argues that songbirds truly are the "canaries in the coal mine"--except the coal mine looks a lot like Earth and we are the hapless excavators.Following the birds on their six-thousand-mile migratory journey, Stutchbury leads us on an ecological field trip to explore firsthand the major threats to songbirds: pesticides, still a major concern decades after Rachel Carson first raised the alarm; the destruction of vital habitat, from the boreal forests of Canada to the diminishing continuous forests of the United States to the grasslands of Argentina; coffee plantations, which push birds out of their forest refuges so we can have our morning fix; the bright lights and structures in our cities, which prove a minefield for migrating birds; and global warming. We could well wake up in the near future and hear no songbirds singing. But we won't just be missing their cheery calls, we'll be missing a vital part of our ecosystem. Without songbirds, our forests would face uncontrolled insect infestations, and our trees, flowers, and gardens would lose a crucial element in their reproductive cycle. As Stutchbury shows, saving songbirds means protecting our ecosystem and ultimately ourselves.Some of the threats to songbirds: - The U.S. annually uses 4-5 million pounds of active ingredient acephate, an insecticide that, even in small quantities, throws off the navigation systems of White-throated sparrows and other songbirds, making them unable to tell north from south. - The U.S. Fish and Wildlife Service conservatively estimated that 4-5 million birds are killed by crashing into communication towers each year.- A Michigan study found that 600 domestic cats killed more than 6,000 birds during a typical 10-week breeding season.

    It was five feet long, with steel-blue scales, luminescent eyes and remarkable limb-like fins, unlike those of any fish she had ever seen. Determined to preserve her unusual find, she searched for days for a way to save it, but ended up with only the skin and a few bones.A charismatic amateur ichthyologist, J.L.B. Smith, saw a thumbnail sketch of the fish and was thunderstruck. He recognized it as a coelacanth (pronounced see-la-kanth), a creature known from fossils dating back 400 million years and thought to have died out with the dinosaurs. With its extraordinary limbs, the coelacanth was believed to be the first fish to crawl from the sea and evolve into reptiles, mammals and eventually mankind. The discovery was immediately dubbed the "greatest scientific find of the century." Smith devoted his life to the search for a complete specimen, afourteen-year odyssey that culminated in a dramatic act of international piracy. As the fame of the coelacanth spread, so did rumors and obsessions. Nations fought over it, multimillion-dollar expeditions were launched, and submarines hand-built to find it. In 1998, the rumors and the truth came together in a gripping climax, which brought the coelacanth back into the international limelight.A Fish Caught in Time is the entrancing story of the most rare and precious fish in the world--our own great uncle forty million times removed.

    The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”―including scientists, ranchers, and passionate citizens―recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them. From the Nevada deserts to the Scottish highlands, Believers are now hard at work restoring these industrious rodents to their former haunts. Eager is a powerful story about one of the world’s most influential species, how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. Ultimately, it’s about how we can learn to coexist, harmoniously and even beneficially, with our fellow travelers on this planet.

     What drives a man to travel to sixty countries and spend a fortune to count birds? And what if that man is your father? Richard Koeppel's obsession began at the age of eleven, in Queens, New York, when he first spotted a Brown Thrasher and promptly jotted the sighting in a notebook. Several decades, one failed marriage, and two sons later, he added an astonishing 517 birds to that list on a single trip to Kenya. Soon after, he ended the last romantic relationship he would ever have, scaled down his medical practice, and decided to see every bird on earth, becoming a "Big Lister," a member of a subculture of competitive bird-watchers worldwide, all pursuing the same goal. Over twenty-five years, he collected more than 7,000 species (of a known 9,600), becoming one of about ten people ever to do so. "To See Every Bird on Earth" explores the thrill of this chase, the all-absorbing crusade at the expense of all else, and travel, to places both dangerous and dull, for the sake of making a check mark in a notebook. It's also the story of obsession-answering the questions why list? and why birds?-and how it defines us. A riveting glimpse into a fascinating subculture, To See Every Bird on Earth traces the love, loss, and reconnection between a father and a son, and explains why birds are so critical to the human search for our place in the world.

    However, for naturalist and scientist Nick Davies, the call is an invitation to solve an enduring puzzle: how does the cuckoo get away with laying its eggs in the nests of other birds and tricking them into raising young cuckoos rather than their own offspring?Early observers who noticed a little warbler feeding a monstrously large cuckoo chick concluded the cuckoo's lack of parental care was the result of faulty design by the Creator, and that the hosts chose to help the poor cuckoo. These quaint views of bad design and benevolence were banished after Charles Darwin proposed that the cuckoo tricks the hosts in an evolutionary battle, where hosts evolve better defenses against cuckoos and cuckoos, in turn, evolve better trickery to outwit the hosts.For the last three decades, Davies has employed observation and field experiments to unravel the details of this evolutionary "arms race" between cuckoos and their hosts. Like a detective, Davies and his colleagues studied adult cuckoo behavior, cuckoo egg markings, and cuckoo chick begging calls to discover exactly how cuckoos trick their hosts. For birding and evolution aficionados, Cuckoo is a lyrical and scientifically satisfying exploration of one of nature's most astonishing and beautiful adaptations.

    Anthropologist and naturalist, Dr. Eiseley reveals life's endless mysteries in his own experiences, departing from their immediacy into meditations on the long past, wandering—intimate with nature—along the paths and byways of time, and then returning to the present.

    With whimsically hip illustrations, every page is an extraordinary look at all kinds of subjects, from mineral formation and the inside of a volcano to what makes sunsets, monarch butterfly migration, the ecosystem of a rotting log, the parts of a bird, the anatomy of a jellyfish, and much, much more.

    In these pages you’ll also meet Maya and Zuni, two orphaned baby hummingbirds who hatched from eggs the size of navy beans, and who are little more than air bubbles fringed with feathers. Their lives hang precariously in the balance—but with human help, they may one day conquer the sky. Snowball is a cockatoo whose dance video went viral on YouTube and who’s now teaching schoolchildren how to dance. You’ll meet Harris’s hawks named Fire and Smoke. And you’ll come to know and love a host of other avian characters who will change your mind forever about who birds really are. Each of these birds shows a different and utterly surprising aspect of what makes a bird a bird—and these are the lessons of Birdology: that birds are far stranger, more wondrous, and at the same time more like us than we might have dared to imagine. In Birdology, beloved author of The Good Good Pig Sy Montgomery explores the essence of the otherworldly creatures we see every day. By way of her adventures with seven birds—wild, tame, exotic, and common—she weaves new scientific insights and narrative to reveal seven kernels of bird wisdom. The first lesson of Birdology is that, no matter how common they are, Birds Are Individuals, as each of Montgomery’s distinctive Ladies clearly shows. In the leech-infested rain forest of Queensland, you’ll come face to face with a cassowary—a 150-pound, man-tall, flightless bird with a helmet of bone on its head and a slashing razor-like toenail with which it (occasionally) eviscerates people—proof that Birds Are Dinosaurs. You’ll learn from hawks that Birds Are Fierce; from pigeons, how Birds Find Their Way Home; from parrots, what it means that Birds Can Talk; and from 50,000 crows who moved into a small city’s downtown, that Birds Are Everywhere. They are the winged aliens who surround us. Birdology explains just how very "other" birds are: Their hearts look like those of crocodiles. They are covered with modified scales, which are called feathers. Their bones are hollow. Their bodies are permeated with extensive air sacs. They have no hands. They give birth to eggs. Yet despite birds’ and humans’ disparate evolutionary paths, we share emotional and intellectual abilities that allow us to communicate and even form deep bonds. When we begin to comprehend who birds really are, we deepen our capacity to approach, understand, and love these otherworldly creatures. And this, ultimately, is the priceless lesson of Birdology: it communicates a heartfelt fascination and awe for birds and restores our connection to these complex, mysterious fellow creatures.
