UPDATE: I love AudubonBirdGuide , but both my wife and I *hate* the new interface! 😡 Whatever Audubon paid to have AudubonBirdGuide redesigned, they lost big-time. The new interface REQUIRES you to create an account, and it's almost impossible to easily find what you're looking for. Dropping my earlier 5-star rating to a generous 2 stars. This reeks.
My wife and I have never been "bird watchers", but since being able to enjoy our morning coffee outside every morning, we've taken to really enjoying the busy company of our feathered friends. I downloaded AudubonBirdGuide to help identify the calls, and WOW! AudubonBirdGuide is terrific. It helps identify the multitude of calls, shapes, colors, regions, etc, and has really opened up our appreciation and knowledge. To cap it off: We were trying to confirm a Carolina Wren on our patio this morning; I opened AudubonBirdGuide and started playing the different calls of the Carolina Wren, and the next thing we knew, this little guy had braved hopping right up next to where we were sitting, trying to locate where the calls were coming from! I silenced my phone momentarily, and he flew a few feet away, but as soon as I started the calls back up, here he came again, trying to find his invisible friend! That alone is enough to merit a 5-star rating for this incredible app. 👍🏼👍🏼👍🏼👍🏼👍🏼
