The Voices of Nature would probably have have been dubbed "how and why animals use sound" rather than "how and why animals communicate." Written by bioacoustics researcher Nicolas Mathevon, the book isn't focused on the rest of animal communication. Much like humans, sound is only a small part of how other animals communicate. Title aside, I did learn a lot from this book even if I did find myself a bit frustrated at times. I'm a birder and loved how much more I learned about birdsong and vocalization than I've read in other books. The sketchbook style illustrations are also a nice addition.
Mathevon mentioned being a former school teacher and it shows in his writing. The style is one of someone very excited to tell his audience all about the topics he researches, complete with copious amounts of exclamation points. He says that the book is written for a large audience but also for fellow scientists. The cutesy way he approaches writing wasn't really for me, but I am also one to enjoy books other people claim are "dry." I like the idea of making this book as accessible as possible and the style likely helps with that. I do think this book needed better editing in this arena though. I would have liked longer sections on topics that I discuss further down with fewer words about him and his colleagues, or unrelated research of his. I like that he used accessible language, explained acoustics in ways one can understand, and regularly reminds the reader of info when referencing previous chapters. When discussing field locations, the world building is great and I feel like I'm there.
Where I struggled most with this book was the constant contradictions the author seems unaware of. This book is a bit tough to discuss because it's far behind in terms of animal liberation or rights, but is still a bit ahead of the average anthropocentric animal researcher. Many of Mathevon's ethical standards were above average for those who conduct research on other animals. He does call out the cruelty of researchers who taped penguins' mouths shut or who deafened birds in labs. He discussed a ton of cool field and computer model research. Albeit I do think he should have discussed the disruption playback causes a bit more.
He contradicts his own ethics a bit, unfortunately. He makes a comment, "we are sometimes cruel, but rarely." Researchers harming animals is not rare at all which he shows further on. While I very much appreciate him breaking with the tradition of many science writers refusing to make any statement about ethics, the throwaway comments coupled with his own deliberate participation is problematic. For instance, he explains how amazing zebra finches are and how they form massive social groups in semi-desert Australia. So, he decided to buy some at a pet store and breed them in cages, keeping some completely alone, to discover that birdsong is different when they have social interaction. Of course it is? What made this even more frustrating is that he then discussed studies showing the same thing in wild birds meaning his caged captive colony never needed to exist to gain this information. He also gushes about the (ab)use of rodents in labs and shows another example of how cold focus on manipulation and results causes one to objectify the subjects. (Don't even get me started on his mention of "autistic" and "schizophrenic" rodents, this is long enough.) We never learn what happens to his and others' lab animals, but I've read enough research to hazard a guess. It almost seems like he has an ethics switch he just flips off if he gets excited about learning something.
I enjoyed that he often mentioned that what humans can grasp is only a small subset of other animals' experiences. He shows a fascination with other animals' lives, giving them credit for having rich and complex worlds. He'd also make sweeping generalizations such as shoe horning animals' behavior into pure dominance hierarchy or claiming female birds sexual selection involves absolutely no thought or consideration, but purely evolutionary imperative. Then he'd hop back again to an understanding that birds likely have personal preferences and that many species have rich social lives. Contradictions like these and others made the book feel like he wrote parts at different times in his life.
Some of my favorite parts of the book were topics I wish he'd written far more about. I love that he includes a discussion of animal emotions and communication. I'd push it a bit further, and as mentioned, he also contradicts himself a bit, but it's still nice to see in a text like this. The idea of cross species emotional contagion was not something I'd read studies about before. Discussion of research blunders and the prevalence of female birdsong was important and enlightening. The discussions of ecoacoustics, noise pollution, and the effects of human sound on other animals and vice versa was very interesting. When each of these sections ended, I was craving more and wish he'd have replaced some of the human stories with more on these topics.
I was further surprised that after all of the extra wordiness, he wrote no conclusion to the book. This would have been a great opportunity to wrap things up for audiences who just took in a ton of info. But, the book just ends.
Overall, I liked and learned a lot from this book. Even though I have many criticisms, it enriched my life and taught me many new things. It's worth picking up even if you only choose to skip around as his writing style allows for repetition. I hope in the future he can get a better hold on some of his assessments and beliefs so that things are less contradictory at times.
