It does exactly what it says it does, and it does it very well. Audubon is continuing their tradition of excellence. EDIT: I upgraded to a new phone, and with the new phone comes a new version of this app. It is frustrating to use now. The new UI in the "Bird ID" section is terrible. The old UI was simple and intuitive. Also, it suggests birds that do not live in my area. Very disappointed in this change. 1 star until problems are corrected.
