The book in this picture was a special gift signed by Roger Troy Peterson and artist friend, Ray Shaw. For a couple of years, the book sat right next to the window at the farm and every time I saw a bird I didn't know I looked it up. The same book now sits next to a window here in Missouri for my wife to do the same thing. However, she'll just ask me what kind of bird it is rather than look it up. Her book is voice activated.
