Warblers are some of the most colorful and beautiful birds in North America with equally interesting songs. But, even though they may be easy to hear or see, they are not always easy to identify. The Peterson Field Guide to Warblers for the iPhone takes all the fully colored images, maps and information about Wood and Olive warblers from the most recent edition of the well-known Peterson Field Guide to Birds of North America, adds crystal clear sounds of their songs and calls, includes image and birdsong quizzes for all the birds, a search function and easy navigation to simplify learning about, comparing and identifying Warblers.
