National Audubon Society Field Guide to North American Birds, Western Region

Introduced in 1977 and completely revised in 1994, these bestselling photographic field guides have become the birding bibles of more than four million enthusiasts. Virtually every bird found in North America is brought to life in a full-color photograph and with textual information on the bird's voice, nesting habits, habitat, range, and interesting behaviors. Accompanying range maps; overhead flight silhouettes; sections on bird-watching, accidental species, and endangered birds make these the most comprehensive field guides to birds available.

Note: the Western Edition covers the Rocky Mountain range and all the states to the west of it, while the Eastern Edition generally covers states east of the Rocky Mountains.

A favorite of birdwatchers (especially those who prefer photographs to illustrations), this field guide, revised for 2000, accounts for the 544 bird species that live in the region west of the Great Plains. The clearly printed color photographs capture birds at rest and in flight; preceded by black-and-white silhouettes, the plates are organized by visually based, intuitive categories--"hawk-like birds," "pigeon-like birds," and "perching birds," for example--that make on-the-fly identification a fairly simple matter. The images are matched by clearly written text that describes a given bird, gives an approximation of its voice, and details its habitat, range, nests, and behavior. Sized to fit in a jacket or backpack pocket, this is a valuable companion for any birding outing in the region. --Gregory McNamee
