The Sibley Field Guide to Birds of Western North America by David Allen Sibley (Author). The Sibley Information to Birds has rapidly turned into the brand new customary of excellence in chicken identification guides, covering more than 810 North American birds in superb detail. Now comes a new moveable information from David Sibley that every birder will want to carry into the field. Compact and complete, this new information options 703 fowl species plus regional populations discovered west of the Rocky Mountains. Accounts embrace stunningly correct illustrations-more than four, 600 in whole-with descriptive caption textual content pointing out the most important field marks. Every entry comprises new textual content regarding frequency, nesting, habits, meals and feeding, voice description, and key identification features.

The Sibley Discipline Information to Birds of Western North America is an indispensable resource for all birders searching for an authoritative and portable guide to the birds of the West.

I have owned several hen books, together with Peterson’s and The Sibley Information to Birds (my two previous favorites), however discover this guide extra helpful as a result of it is smaller (though nonetheless not fortunately totable), you needn’t consult with the again of the guide for maps, and birds are confined to my half of the continent. I additionally find it useful that voice is included within the descriptions, and have used that a number of instances as the tiebreaker.

Whereas I perceive that measurement constraints make it not possible to incorporate all the pieces, I do want the illustrations weren’t primarily profiles. There are many instances I want to know what the hen seems like from the entrance (or even the back, though that’s really asking rather a lot). Due to that I supplement this e-book with the Nationwide Geographic Area Information to the Birds of North America, which features drawings of birds in additional pure postures – much less stylized and at random angles.

I find that the 2 books work very effectively together, but I always reach for Sibley’s first.
