"Better than my book - I have tried or researched all of the bird apps and this is my favorite. I appreciate that the developers put real thought into the usability of this guide on iOS, and in this regard Peterson's and iBird are the top of the heap. However I greatly prefer Peterson's for several reasons: the main screen is organized into useful groups of similar birds, making it quick to use; and the app retains the strengths of the paper Peterson guides, with good illustrations (much more useful than photographs) of similar birds on the same page with lines pointing to important field marks. It is better than my paper field guide in that it includes vocalizations, and range maps are more immediately accessible. Great work!" WA Birder Sep 17, 2011

"Fantastic! - This app is amazing. The user-friendly interface makes it one of the most useful of the birding apps currently available, and the pictures, replete with identification points, are second to none. I am a long time birder and early adopter of nearly every North American birding app and I can honestly say that Peterson Birds is the one I turn to most often." Dylan Figueroa Aug 5, 2011
