Each fall thousands of tundra swans can be seen in the Mississippi River Valley—a migration corridor for many species of waterfowl. Birders in Minnesota may spot the tundra swans as they make their way to favored wintering grounds in coastal regions of the US. They travel in family groups of about a hundred, and if you can’t see them, you’re bound to hear them. Tundra swans are a noisy bunch—they have a high-pitched honking call and are especially vocal while foraging.
