In some ways, <em>The Warbler Guide<\/em> treads some of the same ground, but it does so in its own way, and I have no connection to the authors or the publisher.<\/p>\n<h4>Visuals<\/h4>\n<p>The visuals in this book are tremendous.\u00a0 The quantity and quality of the photographs outstrips anything I&#8217;ve seen in a field guide.<\/p>\n<p>Maybe the best part is the comparison pages, most of which are called &#8220;finder guides&#8221;.\u00a0 You want all the warbler heads on one plate?\u00a0 All the undertails?\u00a0 All the side views?\u00a0 All the song spectrograms?\u00a0 All the flight shots?\u00a0 This book&#8217;s got comparison plates for all of these and more.\u00a0 These pages alone are worth the cover price.<\/p>\n<h4>Layout<\/h4>\n<p>The book&#8217;s layout can be confusing, contributing to an overall sense of &#8220;information overload.&#8221;\u00a0 For example, the Blackburnian Warbler species account proceeds as follows:<\/p>\n<ul>\n<li>Pages 1-2: photos of bright Blackburnians;<\/li>\n<li>Page 3: more photos of bright Blackburnians, plus photos of some comparison species (in this case, Yellow-throated and American Redstart);<\/li>\n<li>Page 4: how to age and sex Blackburnians, plus range maps;<\/li>\n<li>Pages 5-6: spectrograms: Blackburnian on the left, confusion species on the right;<\/li>\n<li>Pages 7-8: photos of drab Blackburnians;<\/li>\n<li>Page 9: more photos of drab Blackburnians, plus comparison species;<\/li>\n<li>Page 10: a full-page photo of a Blackburnian, just to keep the number of pages even.<\/li>\n<\/ul>\n<p>The design makes it hard to tell when you&#8217;re &#8220;home&#8221; in a species account &#8212; that is, when you&#8217;re at the beginning.\u00a0 And the ubiquity of comparison species, both in photos and spectrograms, blurs the borders between accounts even further.\u00a0 If you, like me, are in the habit of scanning photos rather than words when looking for a particular species, then abandon all hope of navigating this book with ease.\u00a0 (If you&#8217;re in the habit of scanning words, you&#8217;re still in some trouble, because all the photos are helpfully labeled.)\u00a0 The only thing that saves this book from complete organizational disaster is the decision to order the species accounts alphabetically rather than taxonomically.\u00a0 Normally I&#8217;m not in favor of this, but here, it&#8217;s a life-saver.<\/p>\n<h4>Spectrograms<\/h4>\n<p>The big news is that<strong> this book has spectrograms!<\/strong>\u00a0 That fact alone makes me want to shout with joy from the rooftops.\u00a0 At last we can see the sounds we&#8217;re describing.\u00a0 This is the first major attempt to use spectrograms for identification since at least the 1980s, and it is long overdue.<\/p>\n<p>It&#8217;s also a watershed moment for birding by ear.\u00a0 A lot of people will use this book to decide whether spectrograms are worth using.\u00a0 I fervently hope they will think so.\u00a0 But based on the way the sounds are taught and presented, I fear that some readers, especially casual birders, may persist in the prevailing misconception that spectrograms are difficult, and &#8220;for experts only.&#8221;\u00a0 If this happens, it will be the fault of the authors&#8217; vocabulary.\u00a0 A choice as simple as using the term &#8220;element&#8221; instead of &#8220;note&#8221; sends the message that song identification is a technical endeavour, not an intuitive one.<\/p>\n<p>Their narrow focus on warblers both hurts them and helps them.\u00a0 It allows them to simplify the discussion to three tone qualities &#8212; &#8220;clear, complex, and buzzy&#8221; &#8212; which is a simple and helpful distinction.\u00a0 But the focus on warblers also tempts them to divide all songs into &#8220;phrases&#8221; and &#8220;sections.&#8221;\u00a0 This terminology is great for explaining the difference between, say, Nashville and Tennessee Warbler songs, but it becomes very awkward when applied to, say, Canada Warbler, forcing the authors to write &#8220;many Phrases, almost all 1 Element&#8221; instead of the much simpler &#8220;almost never repeats a note.&#8221;\u00a0 And their descriptions of &#8220;Expanded&#8221; and &#8220;Compressed&#8221; elements are so opaque that I fear they may do more harm than good.\u00a0 I fear the same for the section on distinguishing between flight calls.<\/p>\n<p>Again, though, they get the visuals right.\u00a0 The spectrograms are high-quality, and underneath each one is a series of symbols intended to give a sense of how the song actually sounds.\u00a0 When it comes to the pitch and rhythm of the sounds, these symbols are pretty intuitive, and they had me hearing the sounds in my head almost immediately.\u00a0 I don&#8217;t know if they&#8217;ll work for everybody, but they might provide a &#8220;stepping stone&#8221; to help beginners translate between picture and sound.<\/p>\n<h4>Sounds<\/h4>\n<p>The book is accompanied by a downloadable playlist of audio files.\u00a0 In a couple of years, we&#8217;re going to forget that serious books on bird ID were ever published <em>without<\/em> accompanying audio files.\u00a0 And we&#8217;ll get used to paying more: it costs an additional $5.99 to download the audio collection.\u00a0 You can purchase it separately from the book if you like.<\/p>\n<p>The audio collection mirrors the book exactly.\u00a0 The sound file named <strong>180 a Blackpoll\u00a0 Chip Call.mp3<\/strong> accompanies spectrogram <strong>a<\/strong> on page 180, making it easy to go back and forth between audio and book.\u00a0 If a particular sound appears more than once in the book (due to being included on multiple comparison pages), then it appears more than once in the audio collection as well. Unfortunately, the naming convention for comparison songs is confusing: <strong>165 d Black-and-white\u00a0 Blackburnian.mp3<\/strong> is the Blackburnian song shown on the comparison page for Black-and-white Warbler.\u00a0 There&#8217;s no Black-and-white Warbler in the audio clip.<\/p>\n<p>The audio files are generally high in quality.\u00a0 They are very short &#8212; a single song or a single call &#8212; and have been assiduously cleaned of background noise.\u00a0 One <em>really<\/em> cool thing is that the audio files use spectrograms as the &#8220;album art,&#8221; so on most devices, the appropriate spectrogram pops right up when you play the song.\u00a0 This little feature, more than any other aspect of the entire project, has the potential to get people visualizing sounds and change the way they listen.<\/p>\n<p>One downside to the audio aesthetic is that it forces a narrow focus on single songs. There&#8217;s little mention of patterns of delivery &#8212; whether consecutive songs are similar or different &#8212; which can be useful for ID at times.\u00a0 More distressingly, the single-serving recordings of chips and flight calls provide zero information about the range of variation in each species&#8217; calls, and the careful scrubbing of background noise makes some of them sound unnatural.\u00a0 Compared to <a title=\"http:\/\/www.oldbird.org\/fcmbirds.htm\" href=\"http:\/\/www.oldbird.org\/fcmbirds.htm\" target=\"_blank\">Evans and O&#8217;Brien&#8217;s CD-ROM of flight calls<\/a>, <em>The Warbler Guide&#8217;s<\/em> recordings are far easier to listen to and compare.\u00a0 But Evans and O&#8217;Brien&#8217;s longer and more natural-sounding clips, even though they often roar with noise, provide lots more information to the ear.<\/p>\n<h4>Biology<\/h4>\n<p>This book is pretty much all identification, all the time.\u00a0 There&#8217;s very little about biology and behavior &#8212; only what the authors deem useful in identification.\u00a0 Many warblers employ a two-category song system, in which different categories of songs are deployed in different patterns for different purposes.\u00a0\u00a0 The research into these song systems is extensive, complex, and mostly absent from this book.\u00a0 Many will applaud the narrow focus on identification, but I, for one, am sorry that the book teaches me little more about these fascinating birds than simply how to tell them apart.<\/p>\n<h4>The bottom line<\/h4>\n<p>All in all, this book is a must-have for serious birders.\u00a0 Beginning and intermediate birders should also check it out, and not be too discouraged by the sheer volume of information.\u00a0 I am confident that this book will enhance the way people <em>look<\/em> at warblers.\u00a0 I am less confident, but ardently hopeful, that it will enhance the way they <em>listen<\/em> to warblers as well.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I am confident that this book will enhance the way people look at warblers.
