Very good app for searching thej world's bird species. Especially now with the last update to show local birds at the top of the list.
I tried this app in Italian (my mother tongue). It's wonderful! A lot of results, with subspecies which I never heard about. The possibility to reproduce the call of the birds, and watch their photos, is must for a birdwatcher. Sometime the search is a little too slow, but apart that, I really like this app.
Pretty good, UI could be prettier but the functionality is great. For free this is unbeatable.
But offcourse its my own app, hope you all like it too. Any feedback is more than welcome
