    Experienced birders use the most easily observed characteristics — size, structure, behavior, and general color patterns — to identify birds even before looking carefully at plumage details. Now birders at all levels can learn how to identify shorebirds quickly and simply. This guide includes more than 870 stunning color photographs, starting with a general impression of the species and progressing to more detailed images of the bird throughout its life cycle. Quiz questions in the captions will engage and challenge all birders and help them benefit from this simplified, commonsense approach to identification.

    An attractive and comprehensive guidebook, this work has been completely revised and updated by the author. The reader will find an easy-to-use text which details the natural history of the plants and animals found in the Galápagos Islands.

    The book includes charts with the recipes, instructions on keeping diets simple and balanced, guidelines on preparation, suggestions for finding ingredients, and how much to feed a dog by body weight. There are recipes for healthy adult dogs, as well as guidelines for puppies, senior dogs, and dogs with health conditions including pancreatitis, renal problems, gastric issues, allergies, heart disease, liver disease, and cancer.Tracing the history of feeding dogs, the author shows when commercial dog food rose and took hold of the market. She discusses canine nutritional needs and provides research on how home-prepared foods can meet pets' needs better than commercial, processed dog food. Written with thorough information for the seasoned raw feeder, this guide can also be easily followed by any newcomer to home-feeding.This revised edition includes new information on special care and feeding of pregnant, newborn, performance, and toy breed dogs as well as senior dog considerations and the safety of the raw food diet for dogs.From the Trade Paperback edition.

    Fully grown they can measure 10 feet and weigh close to 2,000 pounds, but at birth they are just 20 ounces. Creatures that may wander thousands of miles over the course of a year, they begin life in a snowdrift.Human encounters with these legendary beasts are cause for both excitement and apprehension. Tales throughout history describe the ferocity of polar bear attacks on humans; but human hunting of polar bears has exacted a far larger toll, obliging Arctic nations to try to protect their region’s iconic species before it’s too late.Now, however, another threat to the polar bears’ survival has emerged, one that is steadily removing sea ice and the life it supports. Without this habitat, polar bears cannot exist. The Great White Bear celebrates the story of this unique species. Through a blend of history, both natural and human, through myth and reality and observations both personal and scientific, Kieran Mulvaney masterfully provides a context for readers to consider the polar bear, its history, its life, and its uncertain fate.

    Members of the phylum Mollusca are among the most ancient animals on the planet. Their shells provide homes for other animals, and across the ages, people have used shells not only as trinkets but also as a form of money, and as powerful symbols of sex and death, prestige and war.The science and natural history of shells are woven into a compelling narrative, revealing their cultural importance and the ways they have been used by humans over the millennia. (Seashells have even been tapped as a source of mind-bending drugs.) Marine biologist Helen Scales shows how seashells have been sculpted by the fundamental rules of mathematics and evolution; how they gave us color, gems, food, and new medicines.After surviving multiple mass extinctions millions of years ago, molluscs and their shells still face an onslaught of anthropogenic challenges, including climate change and corrosive oceans. But rather than dwelling on all that is lost, Scales emphasizes that seashells offer an accessible way to reconnect people with nature, helping to bridge the gap between ourselves and the living world. Spirals in Time: The Secret Life and Curious Afterlife of Seashells shows why nature matters, and reveals the hidden wonders that you can hold in the palm of your hand.

    A true tale of beauty and obsession, smugglers and scientists, and nature’s most enigmatic creature.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.

    Colorful sidebars and numerous photographs highlight key information and provide extra training tips that every owner will appreciate.

    Just think about different behaviors you see at a dog park: We have a good understanding of what it means when dogs wag their tails—but what about when they sniff and roll on a stinky spot? Why do they play tug-of-war with one dog, while showing their bellies to another? Why are some dogs shy, while others are bold? What goes on in dogs’ heads and hearts—and how much can we know and understand?  Canine Confidential has the answers. Written by award-winning scientist—and lifelong dog lover—Marc Bekoff, it not only brilliantly opens up the world of dog behavior, but also helps us understand how we can make our dogs’ lives the best they can possibly be.  Rooted in the most up-to-date science on cognition and emotion—fields that have exploded in recent years—Canine Confidential is a wonderfully accessible treasure trove of new information and myth-busting. Peeing, we learn, isn’t always marking; grass-eating isn’t always an attempt to trigger vomiting; it’s okay to hug a dog—on their terms; and so much more. There’s still much we don’t know, but at the core of the book is the certainty that dogs do have deep emotional lives, and that as their companions we must try to make those lives as rich and fulfilling as possible. It’s also clear that we must look at dogs as unique individuals and refrain from talking about “the dog.”   Bekoff also considers the practical importance of knowing details about dog behavior. He advocates strongly for positive training—there’s no need to dominate or shame dogs or to make them live in fear—and the detailed information contained in Canine Confidential has a good deal of significance for dog trainers and teachers. He also suggests that trainers should watch and study dogs in various contexts outside of those in which they are dealing with clients, canine and human, with specific needs.    There’s nothing in the world as heartwarming as being greeted by your dog at the end of the workday. Read Canine Confidential, and you’ll be on the road to making your shared lives as happy, healthy, and rewarding as they can possibly be.

    But they are relative newcomers there. They evolved in North America and retain their greatest diversity in South America, while the only wild dromedaries are in Australia.This is a classic example of the contradictions of 'native' and 'invasive' species, a hot issue right now as the flip-side of biodiversity. Do we need to fear invaders? Can we control them? Do we choose the right targets? And are the natives always good guys?Thompson puts forward a fascinating array of narratives to explore this crucial question.

    He was a city boy, unsure of what lay ahead. When he entered the forest, which would go on to become one of the last strongholds of wild tigers, it had a profound effect on him, changing his life forever.For the next forty years, he studied nearly 200 Ranthambhore tigers, spending every waking moment in close proximity to these magnificent animals. Of the various tigers he observed a handful became extra special, and it is these which come to glorious life in this book. They include Padmini, the Queen Mother, the first tiger the author got to know well; Genghis, the master predator, who invented a way of killing prey in water, the first time this had been observed anywhere in the world; Noon, one of his all-time favourites, who received her name because she was most active in the middle of the day; Broken Tooth, an exceptionally gentle male; Laxmi, a devoted mother, whose methods of raising her cubs revolutionized tiger studies; Machli, the most famous tigress in Ranthambhore, and several more.

    Sometimes grizzlies kill people, and in exceptionally rare cases they even eat them. Those incidents are the focus of this book because that's what makes bears so interesting, such a huge part of our culture and our collective imagination.
