Books in Peterson Field Guide Series series

Roger Tory Peterson's unique identification system explains exactly what features to look for to tell one species from another. In each Peterson Field Guide, an author with expertise in the subject and an experienced artist work closely with the editors to ensure that both text and illustrations are accurate. This edition includes 100 color photographs of tracks and signs, more than 1,000 line drawings, and nomenclature for all the mammals of North America. The text includes descriptions of habits, habitats, tracks, signs, and ranges, and is filled with wonderful natural history stories. Olaus J. Murie, one of America's leading mammalogists, has completed fieldwork throughout the United States and Canada, from Labrador to the Aleutian Islands, with special concentration in the Northwest. He wrote The Elk of North America and many articles on natural history. Mark Elbroch is the author of several tracking guides,including two award-winning books, Mammal Tracks and Sign: A Guide to North American Species and, with Eleanor Marks, Bird Tracks and Sign: A Guide to North American Species. He has contributed to numerous North American research projects, from monitoring bears to capturing cougars to inventorying carnivores in dry tropical forests.

The first comprehensive guide to the sounds of eastern North American birds, featuring an innovative visual index that allows readers to quickly look up unfamiliar sounds in the field. Bird songs and calls are just as important as visual field marks in identifying birds. But until now, the only way to learn them was by memorization. With this groundbreaking book, it’s possible to visually distinguish bird sounds and identify birds using a field guide format. At the core of this guide is the spectrogram, a visual graph of sound. With a brief introduction to five key aspects—speed, repetition, pauses, pitch pattern, and tone quality—readers can learn to visualize sounds, without any musical training or auditory memorization. Picturing sounds makes it possible to search this book visually for a bird song heard in the field. The Sound Index groups similar songs together, narrowing the identification choices quickly to a brief list of birds that sound alike. Readers can then turn to the species account for more information and/or listen to the accompanying audio tracks available online, through Cornell's Lab of Ornithology. Identifying birds by sound is arguably the most challenging and important skill in birding. This book makes it vastly easier to master than ever before.

Slim and affordable, FEEDER BIRDS OF EASTERN NORTH AMERICA features Roger Tory Peterson's classic art in a larger format designed especially for the eighty million North Americans who watch and feed birds. This easy-to-use, at-a-glance guide simplifies identification by including only the birds that frequent feeders. And to make it even more convenient, the most commonly seen birds come first, followed by those that are harder to identify or that rarely visit feeders. Range maps, descriptions of birds and foods that attract them, and illustrations are on facing pages, so identification is fast and easy. The brand-new introduction covers important bird-feeding topics, including types of feeders and where to place them, birdbaths, kinds of food and when to feed, plantings that attract birds, and solutions to problems with squirrels and cats. A handy quick-reference list tells what kind of food each species prefers, and a feeder checklist provides a record of birds as they are seen.
