I just finished reading
Man-Eaters of Kumaon by hunter-naturalist Jim Corbett. It details Corbett's experiences in the Kumaon region of India from the 1900 to the 1930s, while hunting man-eating tigers and leopards. One tiger, for example, was responsible for over 400 human deaths.
This guy's tracking skills were nothing short of amazing, sometimes tracking a tiger for many days. He could tell a tiger's age, sex, and size by it's pug marks. Many tigers turned man eater because of injury by gunfire or porcupines. On several occasions he predicted where on it's body a tiger was injured based on it's track.
