"I wrote and illustrated this book to help every inquisitive birder, from novice to expert. Whether you can identify six birds or six hundred, you'll be a better birder if you have a grounding in the real nuts and bolts of what birds look like, and your skills will be even sharper if you know exactly what to look for and how to record what you see." David Allen Sibley
