This EarthCam camera lets you peer into a Peregrine nest on the roof of NRG's
power plant in Waukegan
, Illinois. Field Museum scientist and director of the Chicago Peregrine Falcon Program, Mary Hennen, and her team have launched this online expedition to study falcons. Over the last 20 years, Mary and her fellow team members have helped to successfully reintroduce the federally endangered Peregrine Falcons back into the Midwest.
