Bears are contrary animals. They may be some of the planet's largest predators, but they rarely pick on anything their own size. Our narrator, Armstrong Wedgewood, explores how and why these giant mammals choose to survive on tiny morsels.

By selecting only the small things, they're avoiding the risk of getting eaten themselves.
