Behaviour

Tundra swans feed by reaching below the surface with their long necks to pull up roots and plants. They migrate in family groups, and the young stay with their parents all winter. Most of the eastern population winters on the Chesapeake Bay and in North Carolina, and Georgia birds are usually strays from those flocks.

Why they matter

Tundra swans make one of the longest migrations of any North American waterfowl, from the Arctic coast to the mid-Atlantic, stopping at the same lakes year after year. Their need for large, undisturbed wetlands along the way makes them a measure of how well that chain of wetlands is holding up.

Reproduction and lifecycle

Nest — A large mound of plants near water on the tundra
Eggs — Usually three to five
Incubation — About 31 to 40 days
Cygnets — Leave the nest soon after hatching, guarded by both parents
Flight — At about two to three months
Pairs — Usually for life
Lifespan — Wild birds over twenty years are recorded

Living around people

  • A swan on a Georgia lake in winter is as likely to be a wild tundra swan as an escaped mute swan; a wild one keeps its distance.
  • Swans hit power lines in poor light; a swan grounded near a road or line may be injured.

Misconceptions

  • Any swan in Georgia is someone's pet. Wild tundra swans reach the state in most winters.
