Peterson First Guides are the first books the beginning naturalist needs. Condensed versions of the famous Peterson Field Guides, the First Guides focus on the animals, plants, and other natural things you are most likely to see. They make it fun to get into the field and easy to progress to the full-fledged Peterson Guides.
I purchased this book because of my wildlife management studies, along with other field guides and I would highly recommend it to anyone. Even if you simply have an interest in wildlife, it's a great book. A lot of information, details, and excellent illustrations.
