Penguins Do “Fly”
If you watch a group of Rockhopper penguins move, it’s easy to see why these birds are called “Rockhoppers.” Quite simply, they hop from rock to rock bouncing along on both feet. When walking gets tricky, they use their sharp beaks and nails to hold onto grooves in the rock. Like all penguins, they do not fly—at least not in the air. Using their flipper-like wings to propel them through water, penguins engage in what can only be called underwater flying. As they swim, their legs extend fully backward and they use their feet and small, stiff tail for steering.
