Best North American field guide... again!

There are 3 worthy North American field guides. But the one I carry with me on trips, the one I turn to first, has been updated to compete strongly with the others. Yes, with its 2011 printing, Jon L. Dunn and Jonathan Alderfer did it again with the National Geographic Field Guide to the Birds of North America, now in its 6th Edition!

The back cover advertises: "America's #1 Bird Guide Just Got Even Better!". While I don't necessarily agree with the grammar, I agree with the thought.

You may argue that The Sibley Guide to Birds is your favorite. Fine. That was an amazing book when it first came out, and is still a strong contender. The songbirds shown in flight in that book still haven't been matched by any other guide. But when Sibley's guide first hit the market in 2000, the National Geo was in its 3rd Edition with just over 800 species shown, matching the 810 in Sibley. The 5th Edition of the National Geo was a complete make-over, and this 6th Edition is also a redesign--now with 990 species (including 92 Accidentals and Extinct)!

While many of the illustrations in the National Geo are familiar through all versions of the book, this 6th edition claims 300 new art pieces in addition to all the changes in the 5th Edition! Averaging over 3 illustrations per species (as opposed to 8 for Sibley), the National Geo's bird illustrations are larger and more detailed than Sibley's. I noticed many new illustrations, including standing and close-up head views of jaegers. I notice the goatsuckers no longer have "shrunken heads" as those illustrations were re-done. Many of the warblers were re-drawn. The comparison views of the foreheads of Tundra and Trumpeter Swans are a great new ID illustration.

This new edition places helpful identification text next to the illustrations, making it similar to the arrows and text in Sibley. This seems to add almost 50% more identification text than the previous edition of this guide. Imagine having an expert write additional ID comments next to each illustration in your field guide. Wow!

Following the lead of The Stokes Field Guide to the Birds of North America the new National Geographic guide also heavily stresses field identifiable subspecies, with 59 maps showing subspecies in the main text, and an additional 37 subspecies maps in the appendix.

The subspecies are especially helpful for the white-cheeked geese, carefully delineating range and plumages of the various populations of Canada Goose and Cackling Goose--something birders really need, based on the amount of confusion I have witnessed among birders.

The maps are updated, too. The 3-color maps of the 5th Edition (breeding, winter, year-round) have been replaced with 6-colors (adding 3 different colors for migration: spring, fall, both). Hurray!

The new edition also adds more voice annotations. For instance, previous versions of the guide did not list the distinctive calls of swallows and some shorebirds (Red Knot, Surfbird, Rock Sandpiper)--it does now.

Finally! We now have a field guide that shows North American seabirds correctly and completely! It is updated with rarities and subspecies that may actually be separate species. The illustrations of wing molt in Wilson's Storm-Petrel was a nice surprise.

A new feature is a quick-find index on the front cover, and a visual index to bird families on both front and back covers. These will help newer birders find birds and learn the taxonomic sequence.

All the way around, this is a great field guide. In fact, compared to previous editions (especially the 4rd Edition or earlier), this seems like a brand new field guide to hit the market!

  1. Cool. I picked up the 4th edition for $5 a year or so ago and really like it. I'll have to take a look at this new edition. Thanks for the review!

  2. Comments on ID or errors:

    The Costa's Hummingbird artwork hasn't changed since the first edition. Sadly, with the information presented one cannot tell female Costa's from female Anna's Hummingbird. Costa's is reported rarely out of the SW deserts to at least western Oregon. Sibley is OK in this regard.

    On the cowbird page, the gender symbols are mixed up. The symbols of both male and female Brown-headed Cowbirds are reversed. The male Texas form of Bronzed Cowbird shows a female symbol.

  4. Another error noted by Rick Wright on Horned LArk plate: "the label alpestris for one of the flying birds attached to a perched strigata."

  5. Yikes about the mixup of sex symbols on the cowbird page! Thanks for being the first to point that out. I'll make sure that is corrected when the book goes into its second printing.--Jonathan Alderfer

  6. Well, congratulations on this fine work, Jonathan. The quality of field guides in recent years is astounding, and the competition fierce! Hard on field guide publishers, I would imagine, but great for birders!

  7. Two more minor errors: Snowy Plover should be Charadrius nivosus (the text notes that it was split from C. alexandrius) and in the introduction, in the section on subspecies, Cerulean Warbler is called by its old Dendroica cerulean.

  8. Do you have any familiarity with either of the regional NG editions? If so, how do they compare with this continental 6th edition? Thanks!

    1. I don't have familiarity with local guides, Phillip. Perhaps this should be a topic for another post. Of the nearly 1000 species recorded in North America, over 520 species have been recorded in Oregon alone. That's still a huge number--too large for a beginner guide. So, what do you leave out for beginners? And, if so, then a more advanced (or lucky) birder is sure to see something not in the "reduced" guide or, at least, that may be his goal! Thus, the need for a continental guide.

      IF the status and distribution is considerably better in the local guide, then that would be a worthy effort. If it was just a condensed version of the larger guide, then it has less usefulness, in my opinion.
