Peterson Birds of North America

Decades of research, organization and expertise have gone into making the Peterson Field Guide series the most respected guides to North American natural history in print. Roger Tory Peterson invented the modern field guide and set the standard for all field guides to follow. His classic Peterson Field Guide to Birds of North America is the result of 75 years of continual revision and rework. It is widely considered the most authoritative and the most useful reference on North American birds.

But Peterson guides are more than just a great reference. People all across the US have grown up with Peterson guides. For many, their first introduction to birds and how they differ from one another came from a Peterson book. Peterson guides are a treasure trove of natural and national history.

Appweavers is privileged to bring this tremendous national resource to a wider audience and to continue Roger Tory Peterson’s goal of broadening the appreciation of North American flora and fauna. In the coming months we will be introducing a wide range of mobile apps, designed around the Peterson Field Guide series of books.
