Hummingbirds - Tapa dura

This book is for anyone interested in a fascinating group of animals. The text is easy to understand, but detailed and rich enough for professional ornithologists.

Indeed it is possible to page through this volume dozens of times without tiring of these incredible creatures.-- (03/01/2016) This color-photo-illustrated book will appeal to birders, readers in natural history, and general readers interested in hummingbirds. The first part of the book offers seven chapters on how hummingbirds evolved, how they fly, how they eat and reproduce, why their wing colors are iridescent, and the future of hummingbirds in the face of threats to their environment. This part of book contains color photos and black and white drawings, less than full-page size. The second part of the book is a 180-page portfolio of images by hummingbird photographers Michel and Patricia Fogden, offering full-page photos of hummingbirds in action.-- (03/19/2015) This perfect coffee table book captures the dazzling and fascinating world of the remarkable hovering bird unique to the Americas. Author Ronald Orenstein, a zoologist, lawyer and wild life conservationist, explains in layman's terms many characteristics of hummingbirds, from flight and feeding techniques to migrations and mating patterns. There are more than 340 species of hummingbirds divided into seven groupings with illustrative names like Mangoes, Coquettes, Brilliants, Mountain Gems, Bees, Emerald and Giant. Readers will learn about their diverse habitat, unique metabolisms, courtship prowess and near mythical attraction in pre-Columbian lore of the Americas, and may be surprised to discover that hummingbirds while resting enter a state of hibernation-like torpor to conserve body heat. The spectacular photography of Michael and Patricia Fogden reveals the diversity, beautiful colors and movement of these unique birds. They successfully captured images of the speedy birds in flight, perched, nesting, feeding and, in an exceptional set of photographs, even escaping the fangs of a viper.-- (10/06/2014) There are many, many hummingbird books.

The tiny hummingbird has long been a source of fascination for birdwatchers and naturalists alike. They number 300 species and Ronald Orenstein has a passion for all of them. Hummingbirds are the smallest birds in the world. A hummingbird egg is the size of a pea, barely, and the chick that emerges will be smaller than a penny, if that. But these tiny birds pack a powerful engine: a hummingbird's heart beats more than 1,200 times per minute. Nicknamed the 'avian helicopter', a hummingbird's wings beat from 70 times per second in direct flight, to more than 200 times per second when diving. Not surprisingly, that whirlwind of wing power creates a humming sound. To fuel such energy, hummingbirds must eat as much as eight times their body weight on a daily basis, which means visiting an average of 1,000 flowers - every day - to get enough nectar. Hummingbirds are found in North and South America, with the greatest number in Ecuador, although some species breed as far north as Canada. Most species migrate from Mexico to Alaska, a distance of more than 5,000 miles. In this book Orenstein covers all aspects of hummingbird natural history, their relationship with the plants on which they feed, the miracle of their flight, their elaborate social life and nesting behaviour, and their renowned feats of migration. More than 170 colour photographs of these magnificent creatures, taken in the wild, adorn the pages of Hummingbirds. Birders and natural history readers alike will gain new insight into the tiny bird and revel in the stunning images.
