Jennifer Ackerman’s What an Owl Knows is more than just a book; it’s a portal into the mysterious lives of one of nature’s most enigmatic creatures. I picked up this book with the same casual curiosity I approach many of the nature titles that cross my path at The Thinking Spot, my wife’s bookstore. What I discovered was a captivating exploration that stayed with me long after I turned the final page.
Ackerman, who has previously mesmerized us with her insights into avian intelligence in The Genius of Birds, turns her attention to owls—those silent, nocturnal hunters that have fascinated humans for centuries. What makes this book stand out is not just the breadth of scientific detail, but the way Ackerman weaves together research, personal anecdotes, and cultural history into a narrative that is both informative and deeply engaging.
She invites us to explore the intricate biology of owls, starting with their forward-facing eyes—so large they account for about 3% of the bird’s body weight, a stark contrast to our own minuscule .0003%. This anatomical marvel isn’t just a quirky factoid; it’s the key to their unparalleled night vision and depth perception, essential tools for a predator that relies on stealth and precision. And then there’s the ear asymmetry, a concept I had always found fascinating in a distant, academic sort of way. Ackerman makes it real. She explains how these creatures can pinpoint the exact location of their prey in the dark, down to just two or three degrees, thanks to their extraordinary auditory system—a system so sophisticated it performs complex mathematical computations akin to those used in Bayesian inference.
But what truly makes What an Owl Knows exceptional is how Ackerman balances this scientific rigor with a profound respect for the cultural and symbolic significance of owls. Throughout history, these birds have been seen as symbols of wisdom, omens of death, and everything in between. Ackerman respects these myths while grounding her narrative in the fascinating reality of owl biology and behavior.
Reading this book reminded me of the joy of discovery, the same feeling I get when I dive into a subject and realize how much there is to learn. Ackerman’s ability to convey complex scientific ideas in an accessible and engaging way makes this a book not just for the bird enthusiast, but for anyone with a curiosity about the natural world.
What an Owl Knows is a must-read for anyone who has ever found themselves entranced by the hoot of an owl in the night. It’s a reminder that there’s always more to learn, even about creatures we think we know so well.
So, whether you’re a seasoned birder or just someone who loves a good nature story, I highly recommend picking up a copy. As always, I encourage you to support independent bookstores—grab your copy from The Thinking Spot in Minnetonka or online at Bookshop.org.
