(1) There are seven or eight different species of swans, all share some of the characteristics Yeats describes in the poem "The Wild Swans at Coole." Though some swans weigh as much as 50 pounds, they are graceful in flight with their long, outstretched necks and steady wingstrokes.
(2) Swans which mate for life, producing about six babies (called cygnets) each breeding season. The cygnets are gray or brown; most gradually become white, but a few species have other colorations.
(3) Although the male swan, or cob, will defend his family against outsiders. These families do merge with others to migrate in a large group. Flying at high altitudes, in either diagonal or V-formations, swans travel southward in fall and northward in spring.
