Swans usually mate for life, though "divorce" does sometimes occur, particularly following nesting failure. The number of eggs in each clutch is between 3–8.
Young swans are known as cygnets, from the Latin word for swan, cygnus. The male and female adults are known as cob and pen. The word is derived from Old English swan, akin to German schwan, in turn derived from Indo-European root *swen (to sound, to sing), whence Latin derives sonus (sound). (Webster's New World Dictionary)
Coloration
The Northern Hemisphere species of swan have pure white plumage, but the Southern Hemisphere species are patterned with black. The Australian Black Swan (Cygnus atratus) is completely black except for the white flight feathers on its wings, and the South American Black-necked Swan has a black neck. The Coscoroba Swan, also from southern South America, has black tips to the primary feathers.The legs of swans are dark blackish grey, except for the two South American species, which have pink legs. Bill colour varies; the three far northern species have black bills with varying amounts of yellow, and all the others are patterned red and black. The Mute Swan and Black-necked Swan have a lump at the base of the bill on the upper mandible.

- Perhaps the best known story about a swan is The Ugly Duckling fable. The story centers around a duckling who is mistreated until it becomes evident he is a swan and is accepted into the habitat. He was mistreated because real ducklings are, according to many, more attractive than a cygnet, yet cygnets become swans, which are very attractive creatures.
- Swans are revered in many religions and cultures, especially Hinduism. The Sanskrit word for swan is hamsa or hansa, and it is the vehicle of many deities like the goddess Saraswati. It is mentioned several times in the Vedic literature, and some swans have also been said to have the knowledge of the Supreme Being Brahman. They are said to reside in the summers in the Manasarovar lake and migrate to Indian lakes for the winter, eat pearls, and separate milk from water in a mixture of both. Hindu iconography typically shows the Mute Swan. It is wrongly supposed by many Historians that the word hamsa only means a goose, since today swans are no longer found in India, not even in most zoos. However, ornithological checklists clearly classify several species of swans as vagrant birds in India.
- In Greek mythology, the story of Leda and the Swan recounts that Helen of Troy was conceived in a union of Zeus disguised as a swan and Leda, Queen of Sparta.
- One Chinese idiom about swan is "You are a scoundrel who wants to eat swan meat!" . This idiom refers to people who are rude and ask/demand a reward they shouldn't deserve.
