Ask the Swan Specialist

You are very welcome. Whether the cygnets fly at once, totally depends on the parents and individual swans. Sometimes, the parents (especially if they have been successful parents for many years) will begin to teach everyone how to fly and they will all leave with the whole family during the migration.
If the swans are captive and/or the parents chase once the birds turn white, then this chasing may cause the cygnets to leave at different times. The Regal Swan
