Perfect for backyard birdwatchers: This easy-to-use, at-a-glance guide simplifies identification by including only the birds that frequent bird feeders.   Featuring Roger Tory Peterson's classic art in a larger format, this guide has the most commonly seen birds first, followed by those that are harder to identify or that rarely visit feeders. Range maps, descriptions of birds and foods that attract them, and illustrations are on facing pages, so identification is fast and easy. The introduction covers important bird-feeding topics, including types of feeders and where to place them, birdbaths, kinds of food and when to feed, plantings that attract birds, and solutions to problems with squirrels and cats. A handy quick-reference list tells what kind of food each species prefers, and a feeder checklist provides a record of birds as they are seen. For more than 85 years, Peterson Field Guides have set the standard by which other field guides are measured. Comprehensive and authoritative, they are essential additions to any naturalist's bookshelf or backpack.
