During the winter months eagles congregate along the unfrozen portions of the Upper Mississippi River. The stretch of river from La Crosse, WI south to Priarie du Chien, WI always has a high concentration of these majestic birds. After hitting a population low in early 1970’s the eagle population is once again healthy, and the eagle was removed from the Endangered Species List in 2007. Wisconsin now has more than 1000 pairs of nesting eagles, and more than 200 of those nest in the Upper Mississippi Valley.
