The Great Migration

About 45,000 tundra swans, snow geese, and dozens of other bird species travel from Alaska and parts of Canada to spend the winter on North Carolina’s coast. This great migration gives scientists an opportunity to monitor the health of the population and how it is adapting to environmental changes.
