From prehistoric cave paintings to the prints and etchings of Picasso, owls have captivated and inspired us for millennia. Whether they appear as ancient Athenian symbols of wisdom, ghostly harbingers of death, or the cuddly sidekicks of Harry Potter and Winnie the Pooh, these birds have continued to fascinate and disturb us in equal measure.

From the evolutionary quirks behind their silent flight and rotating heads, to their romantic relationships and parenting styles, What an Owl Knows brings the rich natural history of owls to life. Deftly weaving together science and art, Ackerman journeys into the owl’s moonlit world and asks: what is it about these birds that so enthrals us?
