'Ackerman is a warm and companionable guide, so enthusiastic about her subject that I suspect even the avian-indifferent will be charmed by her encounters with owls and the dedicated people who study them.' —New York Times

‘With their largely nocturnal lifestyles, cryptic plumage and wary nature, owls can be difficult to locate, let alone study. But in recent years, discoveries about these mysterious and otherworldly birds have come thick and fast as radio trackers, infrared cameras, drones, audio lures, DNA analysis and even specially trained sniffer dogs have joined more traditional methods in unlocking their secrets. What an Owl Knows is an accessible, highly readable tour of these discoveries by Jennifer Ackerman’ —Melissa Harrison, The Times

What an Owl Knows eloquently bridges the gap between science and popular assumption to bring us the surprising (and often endearing) facts about these legendarily mysterious birds. Forget what you know, or think you know, because the truth is stranger than fiction!' —James Aldred, author of Goshawk Summer

'Absorbing and exquisitely researched. Ackerman guides the reader around the world, carefully unpacking what it means to be an owl and examining the human relationship with these oft-misunderstood birds.' —Jonathan Slaght, author of Owls of the Eastern Ice

‘Lively and informative… While her [Ackerman's] straightforward style enables easy comprehension for the science-phobic, there is lyricism too… Her sense of wonder runs through the book.’ —TLS
