Tundra swans take flight. Autumn’s swansong
Each autumn thousands of trumpeter swans can be seen on the Mississippi River Valley – a migration corridor for many species of waterfowl. Birdwatchers in Minnesota may spot the trumpeter swans as they make their way to favoured wintering grounds in coastal regions of the United States. The heaviest living bird native to North America, these immense swans have remarkably long necks that are typically held straight both on the water and in flight, as you can see on our homepage.
