Here the author of Grunt and Packing for Mars explores a crossroads of behavioral science and biology that brings us everything from the laser scarecrow to the langur impersonator. Travel to the bear-busy back alleys of Aspen, the gull-vandalized floral displays at the Vatican, and leopard-terrorized hamlets in the Himalayas, then meet the experts trying to broker peace.
