3At the lake or on vacation, keep this tabbed booklet close at hand. Based on Stan Tekiela's best-selling field guides and featuring only Midwest water birds, the booklet is organized by group for quick and easy identification. Narrow your choices by group, and view just a few water birds at a time. The pocket-sized format is much easier to use than laminated foldouts, and the tear-resistant pages help to make the book durable in the field.
