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.

Sparrows are as complicated as they are common. This is an essential guide to identifying 76 kinds, along with a fascinating history of human interactions with them. What, exactly, is a sparrow? All birders (and many non‑birders) have essentially the same mental image of a pelican, a duck, or a flamingo, and a guide dedicated to waxwings or kingfishers would need nothing more than a sketch and a single sentence to satisfactorily identify its subject. Sparrows are harder to pin down. This book covers one family (Passerellidae), which includes towhees and juncos, and 76 members of the sparrow clan. Birds have a human history, too, beginning with their significance to native cultures and continuing through their discovery by science, their taxonomic fortunes and misfortunes, and their prospects for survival in a world with ever less space for wild creatures. This book includes not just facts and measurements, but stories--of how birds got their names and how they were discovered--of their entanglement with human history.
