Peregrine falcons are crow-sized birds of prey known for their speed and beauty. Native to Wisconsin, peregrines originally nested on high bluffs along the Mississippi, St. Croix and Wisconsin rivers as well as the Door Peninsula. In the 1960s, the population declined due to the pesticide DDT, which weakened peregrine eggshells and prevented hatching. As a result, peregrines disappeared from the eastern United States, including Wisconsin. Since 1996, we have been helping re-establish the population. Through 2017, nest boxes at our Pulliam Power Plant in Green Bay and the Weston Power Plant in Rothschild have produced 117 chicks. You can watch and listen to the peregrines on our nest box streaming webcams during the March to July nesting season.
