Birdwatching, Reference 

We humans have strong emotional responses to the voices of the birds. Their songs can soothe the spirit and bring joy to our lives. They can also, like Poe's raven, arouse darker feelings. Listening to their melodic notes, we wonder, are birds really making music? Are they singing only to one another, or do they sing to us too. Poets and musicians have borrowed from and celebrated the songs of birds in their work. Scientists have been inspired by bird song and analyzed it, solving some of its mysteries but leaving many others untouched. MUSIC OF THE BIRDS tells why birds sing and which are the finest singers. It celebrates the many varieties of bird song: flight songs, night songs, and dawn choruses. It explores the messages of poets and shows how to appreciate every bird song we hear, no matter how beautiful or mundane. Music of the Birds will be valuable to anyone interested in birds, from beginner to expert. - from Amzon
