Often when I go to bird club meetings or find myself in the field hanging out with like-minded individuals, a not uncommon question may come up; usually this is some variation of "what is your favorite bird or what was your spark bird?" When I was first asked this question my mind went blank. My favorite bird? It seemed important that I be able to answer this question but I couldn't think what it might be. So I answered with a sideways kind of answer; I picked a bird of my favorite color, the Cerulean Warbler and named that as my favorite. I do like Cerulean Warblers very much. Now that I think of it, I have not seen one in a while and should make a special effort next migration season to make sure I do. But my favorite?
Had I responded that my favorite bird was the Least Flycatcher, I might have been closer to the truth. I think the Empidonax group are thrilling birds to see and hear. But as we all know, there is nothing easy about Empidonax flycatchers - especially the silent birds. So when I learned of a new book about North American flycatchers I had to purchase it. This is my review
Field Guide to North American Flycatchers Empidonax and Pewees by Can-Ty-Lee and Illustrated by Andrew Birch. Copyright © Princeton University Press.
This is an astonishing and spectacular little bird book, like none that I, at least, have ever seen. At 157 pages long including bibliography, index and websites, this book covers all of the North American flycatchers in the most unique and clearest way possible. The author and illustrator have written a completely novel kind of guide that addresses the differences of each species in eleven categories: crown shape, forehead angle, bill length, lower mandible color, tail length, primary projection, eye-ring, etc., etc. The book is attractive, well-organized, easy to read, easy to hold in your hands and take into the field. Although it might be best to do your studying before going into the field. The information is so thorough that the bird will definitely fly before you have time to thumb through the pages.
Especially for Empidonax flycatchers most of us know which are most likely to appear in our regions. In my midwest region these are the Least, Yellow-bellied, Alder, Willow and Acadian flycatchers. I feel most comfortable with identifying Least Flycatchers because during spring migration they are the most common and the most vociferous. The Willow Flycatcher is a close second; it remains to nest through the summer and is not shy about vocalizing. Unless they are vocalizing, the remaining three are challenging to identify. So far so good then for vocalizing males seen during spring migration. But for silent birds, including females, and during fall migration, my confidence crumbles. The book provides the identification tools to study the birds most likely to be in any area of the country. For any given region, this usually is not an unreasonable number when learning about things like crown shape, forehead slope or the other categories and fitting it all together.
The Field Mark Matrix (page 43) is unlike any identifying system I have seen.
