The Hidden Life of Deer

The animal kingdom operates by ancient rules, and the deer in our woods and backyards can teach us many of them—but only if we take the time to notice.

In the fall of 2007 in southern New Hampshire, the acorn crop failed and the animals who depended on it faced starvation. Elizabeth Marshall Thomas began leaving food in small piles around her farmhouse. Soon she had over thirty deer coming to her fields, and her naturalist's eye was riveted. How did they know when to come, all together, and why did they sometimes cooperate, sometimes compete?

Throughout the next twelve months she observed the local deer families as they fought through a rough winter; bred fawns in the spring; fended off coyotes, a bobcat, a bear, and plenty of hunters; and made it to the next fall when the acorn crop was back to normal. As she hiked through her woods, spotting tree rubbings, deer beds, and deer yards, she discovered a vast hidden world. Deer families are run by their mothers. Local families arrange into a hierarchy. They adopt orphans; they occasionally reject a child; they use complex warnings to signal danger; they mark their territories; they master local microclimates to choose their beds; they send countless coded messages that we can read, if only we know what to look for.

Just as she did in her beloved books The Hidden Life of Dogs and Tribe of Tiger, Thomas describes a network of rules that have allowed earth's species to coexist for millions of years. Most of us have lost touch with these rules, yet they are a deep part of us, from our ancient evolutionary past. The Hidden Life of Deer is a narrative masterpiece and a naturalist's delight.
