Peterson Birds is unique in its ability to guide users through the process of identifying birds.
The home screen displays icons representing groups of similar birds. Selecting a group takes the user to the illustrations screen.
The app displays screens of illustrations in the same format as the Peterson Field Guide to Birds book. Using the touch interface, users swipe from right to left to browse through illustrations showing similar looking birds.

From the illustrations screen, a tap opens the range maps display, showing geographic range for all illustrated birds.

Returning to the illustration screen, a single tap activates audio. Users can then tap on each illustration to hear the brds song.

Selecting a bird and tapping the Species Detail icon takes the user to comprehensive details for each species, including photographs of nests and links to similar birds.



Peterson Birds of North America is a field guide to birds for the iPhone, iPod touch, and iPad. The app is designed for flexibility and users can customize many interface elements to suit their specific needs.

Peterson Birds of North America

This is the first time iPhone and iPad users have had access to the full content of Roger Tory Peterson’s classic bird guide, Peterson Field Guide to Birds of North America. The app does a wonderful job of displaying Peterson’s superb illustrations, including the unique Peterson Identification System and the succinct species descriptions that made Peterson Field Guides a model for all bird guides that followed.
Decades of research, organization, design and expertise have gone into making Peterson Field Guide to Birds of North America one of the most highly regarded, and absolutely the most loved, birding field guides in the US. At Appweavers, we have taken this tremendous resource and applied all of that understanding to the new app. We also added information from seven other Peterson Field Guides, including PFG Eastern Birds’ Nests, Western Birds’ Nests, Hawks of North America, Hummingbirds of North America, Warblers, Feeder Birds, and the Peterson Reference Guide to Molt in North American Birds.
Users of the PFG Birds of North America book will instantly recognize the organization and the look and feel of the app. Like the book, we present illustrations of similar species on a single screen for faster identification. We also provide bird songs and maps, so users can further narrow down an identification by range and by sound. And we’ve added the ability to record sightings, check birds off a life list and make new lists, search for birds by state, month, habitat, etc., and customize the interface to suit the user’s specific needs.
