Warblers are among the most challenging birds to identify. They exhibit an array of seasonal plumages and have distinctive yet oft-confused calls and songs. The Warbler Guide enables you to quickly identify any of the 56 species of warblers in the United States and Canada. This groundbreaking guide features more than 1,000 stunning color photos, extensive species accounts with multiple viewing angles, and an entirely new system of vocalization analysis that helps you distinguish songs and calls. The Warbler Guide revolutionizes birdwatching, making warbler identification easier than ever before. For more information, please see the author videos on the Princeton University Press website.

"The Warbler Guide is a reference book which you will want to have on your desk, your night stand or in your car, for contained within its pages is more treasure than any birder could ever hope for. . . . Bravo to authors Tom Stephenson and Scott Whittle for raising the bar by which we judge specialty guides."—Wayne Mones, AudubonMagazine.org

"The Warbler Guide is a fine book crammed with photographs, tips, expert advice, innovation and information designed to help identify a unique and beautiful set of birds."—Phil Slade, Another Bird Blog

"Fantastic and, yes, ground-breaking. . . . There will be no birder north of the Rio Grande who would turn down this book. There will be few who intend to visit North America that would not want to spend time familiarising themselves with the Wood Warblers, and there is no better way for them than to open these pages and get lost in their cornucopia of detail. . . . Everything from sonograms to seasonal variations, confusion species to aging and sexing and with pretty detailed distribution maps as well. The term 'tour de force' sits well upon its wide shoulders."—Fatbirder

"The Warbler Bible has come forth! This is easily the most comprehensive and fantastic warbler specific guide covering North American Warblers. I am amazed and impressed with each of its features. . . . [A] must-have book."—Robert Mortensen, Birding is Fun

"A warbler feast for the eyes, the answer to the prayers of every birder who has seen a glimpse of yellow, black, and white and said, 'If only that leaf wasn't in the way, I'd know that warbler's name.'. . . The Warbler Guide, by Tom Stephenson and Scott Whittle, is not just another bird identification book. . . . The authors have thought long and hard about what makes an identification guide work and then approached it their own way. The auditory descriptions of bird song and chips, based on scientific analysis rather than a subjective translation of sound, present a very different approach to identifying birds by ear. The abundance of photographs, the plethora of charts and finding guides, all printed in brilliant color on lovely paper, the clarity of design, make this book a joy to look at and to use."—Donna Schulman, 10,000 Birds

"Thoroughly detailed. . . . I'll keep this guide close to me and make my warbler identification a lot more simple."—H.J. Ruiz, Avian 101

"The Warbler Guide is a must-have book for every birder. It is comprehensive, easy-to-use, and absolutely gorgeous."—Eddie Callaway, Birdfreak.com

"Stupendous. . . . Each of the 56 species accounts contain at least a dozen photographs, emphasizing various plumage variations—in all, over 1000 stunning color photos grace the book. . . . One of the unique features of this book is that many of these photos are taken from below, which is how you really see warblers in the field. . . . This relatively inexpensive book will aid birders of all abilities in identifying the warblers of America."—Dan Tallman's Bird Blog

"The Warbler Guide is Music to My Eyes! . . . By the coming fall migration The Warbler Guide 'will' be considered the ultimate, must-have guide for any birder serious about identifying the 'butterflies of the avian world.'"—Jerry Jourdan, Jerry's Birding/Digiscoping Blog

"There's never been an ID guide quite like this one. It's as if the publisher told the authors to produce a book on warbler identification that includes everything a birder might ever need. But don't be misled by my enthusiasm for The Warbler Guide. It will not make identifying warblers easy, it just makes it possible. It's still up to every birder to find, see and hear the birds before they turn to this remarkable ID guide."—Scott Shalaway, Exponent Telegram

"Extraordinary. . . . Grab a copy of this guide in time to help with those confusing fall warblers."—Herb Wilson, Portland Press Herald

"This is a beautiful book, chock full of pictures. The best part is that many of the pictures are what we usually see when we see a warbler—from underneath or in flight. . . . An excellent work."—Penny Miller, A Charm of Finches

"When I personally dove into Warbler identification (the species that helped bring me to birding in the first place! Could those colorful birds really be in my backyard in Central New Jersey?!) I pieced together multiple guides that had information on undertail covert colors and tail patterns, as well as song detail and plumage specification. I had to use multiple sources then for what this guide accomplishes itself. That, to be honest, is putting it mildly. . . . I obviously recommend this guide about as highly as I could and I look forward to utilizing it in my future birding adventures!"—Dan Murray, Birding in New Jersey

"This is one of the most remarkable books about bird identification that I've seen in recent years. . . . At last, a field guide that gives bird sounds the attention they deserve! . . . Groundbreaking. . . . The visuals in this book are tremendous. The quantity and quality of the photographs outstrips anything I've seen in a field guide. . . . Maybe the best part is the comparison pages, most of which are called 'finder guides'. You want all the warbler heads on one plate? All the undertails? All the side views? All the song spectrograms? All the flight shots? This book's got comparison plates for all of these and more. These pages alone are worth the cover price. . . . This book is a must-have for serious birders. Beginning and intermediate birders should also check it out, and not be too discouraged by the sheer volume of information."—Nathan Pieplow, Earbirding

"Once you own this book you will never need another reference on the North American wood warblers. . . . Here the whole spectrum of our warblers is on display and wisely compared and contrasted in ways that will make field identification less of a trial for beginners or those seeing a warbler in new territory. In May I saw over 30 species in two weeks at Magee Marsh, Ohio. This book would have certainly helped me sort out what I was seeing, and what I probably missed."—Harry Fuller, Towhee Blog

"Tom Stephenson and Scott Whittle have covered everything you would ever need to identify any North American warbler from visual clues to songs and calls, and placed in a very easy to work with format."—David Lewis, Birds from Behind blog

"Warblers are notorious for giving the observer fleeting and partial views. Field guides on the shelf today, regardless of the number of images offered, ultimately give you one option: extrapolate species from the fragments of information available. Stephenson and Whittle, using photos taken by dozens of photographers, offer you much better ID odds. They accompany the photos with clearly written descriptive text that focuses point-by-point on the major identification marks. Photos of and text describing similar species offer comparison assistance should confusion arise."—Jim Williams, Wingnut blog

"If you're a warbler aficionado, this is, quite simply, the best 36 bucks you'll ever invest. Stephenson and Whittle have produced a visually and aurally spectacular book—the first, and, just maybe, the last word on these intoxicating birds, at least for the foreseeable future. If previous guides get you into college, this one will take you all the way through graduate school. The Warbler Guide is your passport to a birding PhD."—Bruce Fellman, Southern Rhode Island Newspapers

"While I've been known to exaggerate for the sake of emphasis, I will swear under oath that my jaw literally dropped when I opened this book."—Kirby Adams, National Parks Traveler Magazine

"My two hour old analysis of this guide is simple. Oh my gosh, get your hands on a copy! I'm a cynic and not easily impressed—this book has blown me away."—Chuck & Jaye Otte KS Birdlist

"A book so good I'm almost at a loss for words (tough thing for a writer . . .) The explanations [on vocalizations] are the best I've ever come across; about the visual aspects, what you offer the acolyte and expert alike is so visually rich as to make any remarks superfluous. Just get the book, I'd tell my readers, and be dazzled. And well-schooled."—Bruce Fellman, author of the syndicated, The Naturalist's Journal

"The greatest book ever invented. . . . Ever. . . . Really!"—BirdButtz Blogspot

"Ok, there are bird guides and there are bird guides, but you have never seen anything like The Warbler Guide by Tom Stephenson and Scott Whittle, published by Princeton University Press!"—Birder's Report.com

"Wow! . . . Understanding that many warblers are only seen during migration, they are quite small, and tend to inhabit the top of the tree canopy makes them a challenge for every birder from novice to the advanced. Even the experts need a reference source to confirm what they think they've seen—and this guide is it. The visual cues, song, flight patterns, even regional variations of different species are discussed in intricate detail and shown in every possible angle they might be seen in the field through more than 1,000 clear color photos."—Birding Business Magazine

The Warbler Guide, new this summer from Princeton University Press, has met that challenge brilliantly and innovatively, and for one of North America's most beloved and sought-after species groups. . . .
