What is a baby swan called?

A baby swan is called a "cygnet." Cygnets typically have grey or brown feathers when they are first born, which eventually turn into the white feathers characteristic of adult swans as they mature. Cygnets are very dependent on their parents for food, protection, and guidance in their early days, and they will stay close to their parents for several months until they are able to fend for themselves. Swans are known for their strong family bonds, and both parents play a role in raising and caring for their cygnets until they are fully grown.
