Yes, geese can sleep while flying. They have the remarkable ability to rest one hemisphere of their brain at a time, which allows them to keep one eye open and navigate during long migrations. This adaptation is crucial for their long-distance flights, ensuring they're alert to potential threats while still getting necessary rest.
