A very nice book for the bird watcher. It not only gives general information about birds, their physical make up, nesting, incubation etc. It also covers migration. I liked the book because of the simplicity and easiness to use. One page tells about the particular bird's characteristics, locations, habits, mating, incubation and more. On the opposite page is a clear color print of the bird and what egg. I like it because it was quick to look up the bird and I dont' know how many times I have found an egg and wondered what kind it was! Very nice reference book if you enjoy birdwatching.
