In winter, many of Wisconsinâs bald eagles congregate near dams and power plants where there is open water. Great places to see them include the Wisconsin River in Sauk Prairie, along the Mississippi River and at several locations along the Fox River. Bald eagles are a common sight today in Wisconsin, but in the late 1960s, there were fewer than 490 nesting pairs, down from an estimated 100,000 nesting pairs.
