Swans
on the Move!
Both Tundra and Trumpeter Swans
are heading north. Lucky people throughout the midwestern states and central
provinces have been outside at the right moment, right when a flock wings
overhead. Their haunting cries, beautiful plumage, and interesting life
history make swans among the most beloved of migrants. They begin their
journey on their wintering grounds along the Atlantic coast, and travel
all the way to Alaska and the Canadian Arctic, where they will build their
nests. Tundra Swans spend HALF of their lifetime migrating back and forth
between their wintering and summering grounds!
Following
the long winter, Tundra Swans begin migration with their lowest body weight
of the year. The places where they rest during their journey, called "staging
areas," are critical to their health and their ability to reproduce.
Swans stay at their staging areas for two to three weeks at a time while
fattening up. They will make their nests in Alaska and the Canadian Arctic,
where days are long but the season is short, and their babies will have
a lot of growing to do in the short time before they head south again.
