Peterson Field
Guides
The Peterson Field Guides employ a unique identification system, which
has been called "the greatest invention since binoculars." Each guide
pinpoints key field marks for quick recognition and easy comparison of
species. All guides are illustrated with drawings and photographs in
color and black and white, and all provide up-to-date range information
and the most useful descriptions you'll find anywhere. 4-1/2" x 7-1/4"
standard format. |
