A comprehensive field guide that uses an innovative Sound Index to allow readers to quickly identify unfamiliar songs and calls of birds in western North America. Bird songs and calls are at least as important as visual field marks in identifying birds. Yet short of memorizing each bird’s repertoire, it’s difficult to sort through them all. Now, with the western edition of 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 translate what they hear into visual recognition, without any musical training or auditory memorization. The Sound Index groups similar songs together, narrowing the identification choices quickly to a brief list of birds that are likely to be confused because of the similarity of their songs. Readers can then turn to the species account for more information and/or listen to the accompanying audio tracks available online. 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.

Roger Tory Peterson had already made his mark with his innovative field guide when he conducted DDT research during World War II. His friend and fellow naturalist Rachel Carson built on these efforts and eventually wrote Silent Spring, a landmark text that, along with Peterson’s field guide, jump-started the modern environmental movement. By combining the tireless observation of a scientist with the imaginative skills of an artist and writer, Peterson created a field guide that Robert Bateman, in his foreword to the fifth edition, says was the doorway for millions of people into the wonderland of natural history. The Peterson Identification System has been used in the more than fifty books that make up the Peterson Field Guide series. Peterson’s magnum opus, now in its fifth edition, created the trail for countless field guides to follow. They are still following year by year, but his is the standard by which all other field guides are judged. On the morning of July 28, 1996, Roger Peterson was painting his final bird plate. He died peacefully in his sleep later that day. It is fitting that his final work—a culmination of more than sixty years of observing, painting, and writing—should be this one, a revision of the guide that started his legacy.
