The Wisconsin Department of Natural Resources announced recently that eagle surveys show a very strong resurgence of nesting pairs. Eagles have recolonized almost every county in the state and, in some areas, have appeared to be near a population maximum. In the Minneapolis-St. Paul metropolitan area, where the Mississippi River corridor is designated as the Mississippi National River and Recreation Area, rebounding eagle populations have been documented through several years’ of intensive survey and scientific measurement. The soaring eagle population is widely understood as a strong indicator of better water quality in the river.
