I can see why this app costs money, as far as i can tell it has every bird in it and multiple versions for each bird. The owls are my favorite. And the feature that sets you up for your region is perfect, I'm actually calling birds too me now! lol, so cool.
This is great for any birder! Birding by ear is a difficult skill to obtain. This makes training fun and easy.
In this release, we fixed some bugs and added more attributions.
Note: please make sure you have an internet connection when you open the app for the first time after downloading the app or installing an update.
