The Snowy Owl family on the North Slope of Alaska needs to move toward a new home. Daddy Owl has already scouted out a new place to live. Since the baby owls can't fly yet, they have to walk. And when they get to a river, they have no choice but to swim across it.
As this scene from Nature illustrates, they're quite good at it! Even without swimming lessons, the baby owls figure out how to row across the water with their wings.
