Memory is not their guide — no one butterfly makes the round trip — but each year somehow find their way to the same fifty acres of forest on the high slopes of Mexico’s Neovolcanic Mountains, and then make the return trip in the spring.In Four Wings and a Prayer, Sue Halpern sets off on an adventure to delve into the secrets behind this extraordinary phenomenon. She visits scientists and butterfly lovers across the country, offering a keenly observed portrait of the monarchs’ migration and of the people for whom they have become a glorious obsession. Combining science, memoir, and travel writing, Four Wings and a Prayer is an absorbing travelogue and a fascinating meditation on a profound mystery of the natural world.

    Since reptiles are cold-blooded creatures, most humans don't instinctively understand their requirements the way they understand the needs of a cat or dog. Herp expert Philippe de Vosjoli and his team of veterinarians and authors seek to make keepers confident in their ability to properly care for their bearded dragons through this most informative book. A key component of caring for bearded dragons, according to the authors, is recognizing that their needs change as they develop. De Vosjoli states in the introduction to the book, "Looking at the life stages of bearded dragons also made [the authors] aware that, like humans, they undergo changes in growth and behavior, which may require the dedicated owner to make adjustments in husbandry (and general care) to meet the needs of each life style." The Bearded Dragon Manual is the first book to present this information that is so critical to the proper maintenance of these very popular reptiles.Colorfully illustrated, The Bearded Dragon Manual provides chapter-length coverage on the following topics: selecting a dragon, making a home for a dragon, heating and lighting, diet and feeding management, and behavior. The feeding chapter, which includes as age-by-age guide to nutrition, was co-written with veterinarian Dr. Susan Donoghue. A chapter on breeding discusses strategies for breeding dragons, requirements, conditioning, incubation, and potential problems encountered. Lizard vet extraordinaire Dr. Roger Klingenberg has written a chapter on recognizing and treating bearded dragon diseases, in which he discusses how to recognize a sick dragon, various internal and external parasites, nutritional disorders as well as kidney disease, prolapses, egg-binding, respiratory infections, and eye problems. The chapter concludes with a four-page chart for troubleshooting health problems. Herb expert Jerry Cole has provided a special chapter on frilled dragons, an agamid similar to the bearded dragon that has attracted many bearded dragon fans. Appendices and index included.

    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.

    Join acclaimed naturalist Sir David Attenborough as he travels to the far corners of the Earth to tell the epic story of these animals in this companion to the television series. Discover the secrets of their astounding success--and the profound implications of their uncertain future.Amphibians and reptiles once ruled the planet, and their descendants exhibit some of the most colorful variety and astounding behavior known to the animal kingdom. What are the origins of these creatures? How have they transformed themselves into the beautiful and bizarre forms found today? In this gorgeously illustrated book, Attenborough gets up close and personal with the living descendants of the first vertebrates ever to colonize the land, and through them traces the fascinating history of their pioneering ancestors. He explains the ways amphibians and reptiles have changed little from their prehistoric forebears while also demonstrating how they have adapted and evolved into diverse new forms, some of them beyond our wildest imaginings. And Attenborough raises awareness of the threats global warming and other man-made environmental changes pose to many of these creatures. Life in Cold Blood inspires a genuine sense of wonder about amphibians and reptiles and the marvels of the natural world around us.

    And so, with a scientist's training and a nature lover's boundless enthusiasm, he set out to understand the travails and triumphs of the Canada geese living in the beaver bog adjacent to his home. In The Geese of Beaver Bog, Heinrich takes his readers through mud, icy waters, and overgrown sedge hummocks to unravel the mysteries behind heated battles, suspicious nest raids, jealous outbursts, and more. With deft insight and infectious good humor, he sheds light on how geese live and why they behave as they do. Far from staid or predictable, the lives of geese are packed with adventure and full of surprises. Illustrated throughout with Heinrich's trademark sketches and featuring beautiful four-color photographs, The Geese of Beaver Bog is part love story, part science experiment, and wholly delightful.

    

    Amateur and expert alike can quickly and accurately identify almost any wildflower using Lawrence Newcomb's system, which is based on natural structural features that are easily visible even to the untrained eye. Every time you see an unknown plant, ask yourself the same five questions (related to the type of plant and the structure of its petals and leaves), and you will be directed to the page on which the plant can be found. Beautiful illustrations make confirmation easy.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    And survival is never a given. Somehow, a blind, defenseless tiger kitten must evolve into a deadly, efficient predator; a chimp must learn to distinguish edible plants from lethal poisons; a baby buffalo must be able to pick its mother out of a herd of hundreds. Contrary to common belief, not everything is "hardwired" -- or instinctual -- in the animal kingdom. Many skills a wild animal needs to thrive, to grow, to be what nature intended, must be developed through play, painstaking teaching, and often treacherous trial and error. The coming-of-age processes of the myriad creatures of plain, forest, ocean, and jungle are truly fascinating and often astonishing natural events.In Becoming a Tiger, Susan McCarthy, co-author of the critically acclaimed New York Times bestseller When Elephants Weep, offers readers an in-depth look into the amazing ways baby animals learn not only about themselves, but about their world and ours -- and how to survive in both. Based on extensive scientific research done in the lab, in controlled "natural" settings, as well as in the wild, her findings provide stunning new insights into the lives and development of Earth's nonhuman inhabitants -- not only tigers, but lions, bears, bats, rats, birds, dolphins, whales, apes, elephants, and dozens of other species.Sharing stories and discoveries at once captivating, funny, breathtaking, provocative, and heartwarming, Susan McCarthy carries us on a remarkable journey into untamed places, immersing us in the fascinating, complex, and hitherto unimagined societies and cultures of the beasts and birds. Along the way she shines a brilliant new light on subjects scientists, biologists, and zoologists have only begun to explore, revealing startling truths about the behavior, and sometimes humanlike foibles, of creatures great and small.Warm, informative, and beautifully written, Becoming a Tiger is an enthralling reading experience for animal lovers everywhere. In the transformation tales of playful pups, big-footed cubs, and scrawny chicks becoming deadly hunters, able foragers, and deft nest-builders are valuable and enriching life lessons for members of our own inquisitive, ever-developing species.
