Beautiful illustrations, not easy to use

What sets this apart from the other illustrated bird apps is the number of excellent illustrations and bird songs. The included information is comprehensive, as well. However, the plain text (no illustrations) of birds in what functions as a table of contents, makes finding what you are looking for difficult unless you already know. Therefore I never refer to it in the field. If it remedies this, it could replace iBird, but Audubons unique features and Petersons ease of us keep them among my most-used birding apps.
