When we say someone "eats like a bird," that should mean the person eats a LOT. Every day birds eat many times their weight in food, so they have energy to fly. But hopefully eating like a bird doesn't mean eating what a bird eats. Some birds eat tasty berries and fish. But a few -- the robin, the woodcock, and the warbler -- eat worms. As the birds walk around, their stomping makes the earthworms underground move around, making it easy for the birds to find them. Yum!
