The Peterson Field Guide is the original field guide to birds and has been the leading resource for over 70 years in identifying backyard birds. The most popular birds in your area can now come directly to you on your iPhone, personalized to the zip code you select. No more going through page after page to find the bird you are looking at. Now you can just scroll through a list of images tailored to your location to identify the backyard birds at your feeder.

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.
