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:

“But all is changed, that high horse riderless,
Though mounted in that saddle Homer rode
Where the swan drifts upon a darkening flood.”
—William Butler Yeats (1865–1939)

“And of the swan in death these dreamers tell
of its last flight and how it falls, a plummet,
pierced by the freezing bullet
and how three feathers, loosened by the shot,
descend like snow upon it.”
—Patricia K. Page (b. 1916)

“The reason is:
rats leave the sinking ship
but we . . .
we . . .
didn’t leave,
so the ship
didn’t sink,
and that’s madness,
Lear’s song
that’s Touchstone’s forest jest,
that’s swan of Avon logic.”
—Hilda Doolittle (1886–1961)
