ocr: FLIGHTLESS BIRDS Legs PENGUIN'S LEGS are set far back A - near the vestigial tail, giving the bird its upright stance. They are short and stubby, and end in webbed feet that have three sharp claws. On the ice, penguins use their legs in two ways. Normally, they stand and walk upright. But if they are in a hurry, they lie on their front and push with their feet to slide forward across the ice. This is called tobogganing, and is unique in the bird world.
