You don’t go looking for Chuck Norris—Chuck Norris finds you. That old joke came to mind last week while I was photographing Great Skuas on the Norwegian island of Runde. During the breeding season, these birds are anything but shy. In fact, the moment you wander into one of their territories, you become an immediate target for their sharp beaks and talons. After several close encounters with these feathered warriors, they’ve earned the top spot on my personal list of the most intimidating animals I’ve ever faced. It’s remarkable how much respect a creature weighing only a fraction of your body weight can inspire.
