Peterson Birds of North America For The IPhone, IPod Touch, and IPad

Appweavers, Inc., is the exclusive licensee of the Peterson field guides for mobile devices. The company has worked with Houghton Mifflin Harcourt to develop the Peterson Birds of North America and Peterson Feeder Birds of North America apps for the iPhone, iPod Touch, and iPad. In December 2010, Appweavers released Peterson Birds of North America. The app includes all plates of Roger Tory Peterson's drawings from the Peterson Field Guide to Birds of North America book, with details on 820 species of birds found in North America. The Peterson Birds of North America app also includes information from seven further books in the Peterson field guide series: Peterson Reference Guide to Molt in North American Birds, Peterson Field Guides Hawks North America, Peterson Field Guides Hummingbirds of North America, Peterson Field Guides Warblers of North America, Peterson Field Guides Eastern Bird’s Nests, Peterson Field Guides Western Bird’s Nests, and Peterson Field Guides Feeder Birds Eastern North America.

In April 2011, Appweavers released Peterson Feeder Birds of North America for the iPhone, iPod touch, and iPad. This free app has the same core functionality of the primary Peterson Birds app, but includes details on 160 backyard birds.

Both Peterson Birds and Peterson Feeder Birds apps feature recordings of bird songs from the Cornell Lab of Ornithology Macaulay Library. The apps uniquely enable users to compare songs while looking at illustrations of similar birds. Tapping an illustration on the screen of the mobile device plays the recording associated with that species.

Appweavers also developed a series of checklists based on information from the Cornell Lab of Ornithology eBird database. These Bird Finder checklists are automatically loaded into the app when the user taps on a specially formatted link on the petersonguides.com website. The company provides lists for every North American birding hotspot recorded in the eBird database, and for every county in the US and Canada. Each list includes only those species commonly found at that location, and provides indicators showing anticipated abundance of birds for each week of the year.
