My Absolutely Favorite App

This app is not only easy to use and full of information, but its also a lovely heartening thing.
I love birds and birdsong and all the purity of nature they represent and this is present here in abundance, so that I listen to it often just for the joy of it.
It is very helpful if you hear or see a bird you just cant place. Easy to look up and also links to other places if you want to learn more.
