The cygnets find their food by themselves. Cygnets usually eat bugs instead of weeds and grasses. The cygnets can't fly because they don't have flight feathers yet. Animals don't eat adult swans, but they eat baby swans or cygnets. By three years of age the cygnets go find a mate.
Most swans migrate.
Mute swans don't migrate. Swans that migrate use the same route every year and go to the same migrating place each year. The swans find their way by the sun, moon, and stars. Tundra swans fly the farthest, more than 2,000 miles. They can fly faster than a horse can run.
