Organized by type of bird and type of call. I had to buy it after borrowing from the library. My eyes are so bad I can't identify most birds by sight, but I do enjoy listening to the songs. ( )

I have also been intermittently listening to Birding by Ear. This is a life changing audiobook that teaches the listener how to identify birdsongs and calls. I say "life changing" because once you begin to listen to it, you begin to truly notice the bird song all around you. It is as though you hear voices speaking in a foreign language who are desperately trying to make you understand them. As you begin to identify them by their voices, your appreciation of nature and your every day surroundings is increased more than you might think. ( )
