The best app for birding guide

I really like the overall feature set of this app, including
1. It has both bird illustrations and photos
2. Various modes of bird sound playing
3. BAM is great. It can be better to leverage eBirds public API to get actual sightings
4. Integration with Dropbox is just awesome!

Highly recommend it for all birders.
