COUGARS ON THE CLIFF: One Man's Pioneering Quest to Understand the Mythical Mountain Lion

Recounts the early years of Hornocker's research, when he tracked mountain lions following a dog's nose and footprints in the snow, before telemetry was available. He was the first to learn that mountain lions living in stable populations limit their own numbers through territoriality and a concept he called "mutual avoidance." Well illustrated, some in color.
