Swan
Swans, genus Cygnus, are birds of the family Anatidae, which also includes geese and ducks. Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae. There are six or seven species of swan in the genus Cygnus; in addition there is another species known as the Coscoroba Swan, although this species is no longer considered one of the true swans. Swans usually mate for life, though 'divorce' does sometimes occur, particularly following nesting failure. The number of eggs in each clutch ranges from three to eight.

Famous quotes containing the word swan:
“Love that had robbed us of immortal things,
This little moment mercifully gave,
Where I have seen across the twilight wave
The swan sail with her young beneath her wings.”

Did never whiter shew,
Nor Jove himself, when he a swan would be
For love of Leda, whiter did appear:”

Upon a fading gleam,
Float out upon a long
Last reach of glittering stream
And there sing his last song.”
