I bought this book for a college level ornithology calss and did not find it very helpful. I very much perfer the Peterson's field guide. The illustrations are not very detailed, and often look confusingly similar to one another. Unfortunately, the Peterson's foeld guide comes in two seperate volumes, and there is much overlap. This book is nice in that it covers the entire country in one concise volume. But, if you are planning on traveling and bringing your field guide with you, I feel that the Peterson's field guides are a much better choice.
