This is an excellent book, very easy to use and a pleasure to own. Its most obvious benefits are the clear illustrations which I have used repeatedly to identify birds quite new to me. Each page of pictures is placed immediately adjacent to an equally simple distribution map, a layout which has repeatedly got me out of trouble and allowed me to differentiate between similar birds with different ranges. At the front there is a nicely written section explaining how the guide works and helping with identification. I am not a bird watcher, but I live in Nigeria and spend a lot of time in the garden with camera, binoculars and the book. Very strongly recommended by me, the amateur, and equally so by my semi-professional mentor.
