The Sibley Field Guide to Birds of Western North America

Rating:
Summary: Exceptional
Review: The larger Sibley field guide caused quite a stir but it was also a bit of a bear, in terms of size. The smaller guides that focus on east and west, are much easier to carry. Everything about them is, really, as good as it gets: the paintings, the maps, the descriptions - a top quality product.

Summary: The best field guide out there!
Review: This field guide is the best for visual bird identification. All info is in one place, there are side-by-side comparison plates, and different plumages. Some of the maps are a bit off and there's no behavioral information to assist an ID (just like the big Sibley's book). It's also missing some of the great extras that makes the big Sibley's so invaluable. I still regularly use the big book to supplement the info here, but this is the best field guide I have.
