Statistically speaking, North America's black bear is a surprisingly considerate predator, averaging less than one human fatality every three years and politely retreating 75% of the time if you fight back, yet it still demands the utmost respect—especially from anyone foolish enough to approach a mother with cubs in the fall without bear spray.
