Marty Stouffer's Wild America S05 E05 River of Bears

Each summer, as Salmon make their spawning run, a gathering of the largest carnivores in North America also takes place. Up to a hundred huge Brown Bears line up along the McNeil River in Alaska. Each Bear stakes out and defends its fishing territory. The cast of characters includes sows with playful cubs, battle-scarred boars, and juveniles, with comical fishing styles.
