From the author of The Genius of Birds and The Bird Way, a brilliant scientific investigation into owls—the most elusive of birds—and why they exert such a hold on human imagination
With their forward gaze and quiet flight, owls are often a symbol of wisdom, knowledge, and foresight. But what does an owl really know? And what do we really know about owls? Some two hundred sixty species of owls exist today, and they reside on every continent except Antarctica, but they are far more difficult to find and study than other birds because they are cryptic, camouflaged, and mostly active at night. Though human fascination with owls goes back centuries, scientists have only recently begun to understand the complex nature of these extraordinary birds.
In What an Owl Knows, Jennifer Ackerman joins scientists in the field and explores how researchers are using modern technology and tools to learn how owls communicate, hunt, court, mate, raise their young, and move about from season to season. Ackerman brings this research alive with her own personal field observations; the result is an awe-inspiring exploration of owls across the globe and through human history, and a spellbinding account of the world’s most enigmatic group of birds.
PUBLISHERS WEEKLY
In this masterful survey, nature writer Ackerman (The Bird Way) explores the physiology and behavior of owls. She provides an overview of owls' intelligence, evolution, mating strategies, nest-building abilities, and communication skills, relating how variations in owl calls allow the birds to express "their needs and desires" and convey "highly specific information about their individual identity, and their sex, size, weight, and state of mind." Describing academic studies that illuminate the surprising social complexity of the nocturnal predators, Ackerman writes that nestling barn owls will altruistically share food with weaker siblings, and that screech owls sometimes engage in cannibalism, killing and eating fellow fledglings. The author highlights the heterogeneity of owl species, noting that they're found on every continent but Antarctica and that while the Eurasian eagle owl is big enough to prey on baby deer, the tiny elf owl is only "about the size of a small pine cone." There's fascinating trivia on every page (owls perform "sophisticated mathematical computations" to pinpoint prey by sound, and some owl attacks on humans may be attempts to play), making for a revelatory glimpse into the lives of the "enigmatic" raptors. Bird lovers will be enthralled. Photos.
