Young swans are called cygnets. Swans usually mate for life, though "divorce" does sometimes occur, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another. The number of eggs in each clutch ranges from three to eight. Young swans are known as swanlings or as cygnets.
Swans are the largest extant members of the waterfowl family Anatidae, and are among the largest flying birds. Although birds do not have teeth, swans have beaks with serrated edges that look like small jagged 'teeth' as part of their beaks used for catching and eating aquatic plants and algae, but also mollusks, small fish, frogs and worms.
