Good, but could be great...
Intuitive, interesting, and in touch with what a user wants for bird identifications. However, It needs to take the next steps to truly make it a daily must have in the field which is integration with eBird, filtering by state, and peek arrival and departure dates for each species which would make this app 5 stars and twice as valuable!
