'This is a first-class book. If you are interested in wildlife and the outdoors, you will find it an essential addition to your natural-history library. The author's knowledge and enthusiasm come right through, and the illustrator's work greatly enhances the book's usefulness. Organization of the book makes identification easier than with other track books I know and should enable beginners to use the text with ease.'--Jim Rantz, Executive Director, The National Outdoor Leadership School.
