I don't want to harp on this book or the author too much in this review; clearly the guy is passionate about this topic and dead-set on his goal of finding one of these birds, but this book was really difficult to get through.
I'll always enjoy a book set in the field, and I love hearing about the day-to-day tasks of adapting to the research environment, tinkering with technology, and altering one's research approach as an experiment continues, but that was this book's only saving grace. The rest was a constant, borderline unreadable pattern of describing some call, nest site, or "sighting" that "was just out of frame on our cameras" or "backlit" or "too far away," and it all comes off as extremely sad, to be quite honest. I'm not saying that every scientific endeavor has to be a home run; in fact, I think failures can teach a lot more than successes, but the only reason this book appears to be published is to "supplement" Dr. Hill's nonexistent evidence for the woodpecker, which also comes off as embarrassingly excessive as Hill seemingly "finds" up to *TEN BREEDING PAIRS* of a bird that has been extinct since the mid-40s. Every line of reasoning he provides, both as to why all of these massive, sharply patterned birds were living undetected in a relatively populous state for decades, and why he and his team of multiple people all dedicated to the task for months can't get a single decent picture of, again, a brilliantly patterned, very loud, foot-and-a-half-long bird, comes off as a pitiful excuse for a man's inability to come to terms with the fact that the bird is gone.
I was going to try to review this book on the basis of its literary value rather than as a scientific text, but Hill's desperate, completely unfounded, and increasingly absurd claims about what he saw and heard throughout his experiment leach any purely literary enjoyment from the book as well; I can thoroughly enjoy well-written books about subjects I personally disagree with, but this is more like trying to enjoy a novel-length Facebook post from a family conspiracy theorist.
At least the Facebook conspiracy theorist isn't trying to pull grant money away from legitimate conservation efforts.
