Now completely revised and updated – the indispensable resource for all birders seeking an authoritative guide to the birds of the West in a portable format they will want to carry into the field.
Compact and comprehensive, The Sibley Field Guide to Birds of Western North America features 715 bird species, plus regional populations, found west of the Rocky Mountains. Entries include stunningly accurate illustrations – more than 5,046 in total – with descriptive captions pointing out the most important field marks. Each entry has been updated to include the most current information concerning frequency, nesting, behaviour, food and feeding, voice description, and key identification features. Here too are more than 652 updated maps drawn from information contributed by 110 regional experts across the continent, and showing winter, summer, year-round, migration, and rare ranges.
New and improved:
- Updated habitat, description, behaviour, and conservation text for each species account and all family pages (drawn from the second edition of The Sibley Guide to Birds and tailored for the specific region).
- All illustrations, including new and revised illustrations of species and regional forms, are taken from the rescanned and meticulously color-corrected second printing of the second edition of the Sibley Guide.
- New design reflects the layout of The Sibley Guide to Birds, Second Edition. All species accounts are now presented in columns, rather than stacked, allowing for better comparison and more illustrations and text for each species.
- Current taxonomic order and up-to-date common names.
- All maps revised to reflect the most current range information.
- More species and rarities included.
"[...] The new guides are pocket-sized, though still a hefty carry, and have been completely updated for habitat, description, etc. The illustrations have also been revised, the quality still first-class, and the books have been reorganized to allow for the currently approved taxonomy [...] There is, necessarily, duplication between the volumes as some species do not recognize the Rocky Mountains as a continental divide in the way we humans might wish, but overall the two-volume approach works well. Thoroughly recommended."
– Richard Sale, Ibis
"The second editions contain similar great content to the first, but have titles more in proportion to their size, the front cover stating, baldly, Sibley Birds East (or West). The biggest differences are in the organisation. The species order has, inevitably, been changed to reflect current taxonomic fashion and the page layout has been changed from horizontal to vertical. In principle, this makes it easier to compare different plumages, but, in practise, I’m not sure it makes that much difference. The other obvious difference is that all the images have been ‘digitally re-mastered’, so are more vivid and with greater contrast; whether you consider this an improvement on the previous, rather delicate, images may come down to personal taste. The text (especially the voice section) and maps have been comprehensively revised and updated to reflect latest knowledge. As before the books come bound in a water-resistant cover, which stands up fairly well to the rigours of the field [...] if you are going birding in North America, these are still the guides to get [...]"
