Eagle Cliff in New Hampshire’s Franconia Notch State Park is an important nesting site for Peregrine Falcons. Each year, popular climbing routes in the area close temporarily to give nesting falcons their space. After peregrines disappeared from the northeast due to the pesticide DDT, Eagle Cliff was the first natural rock face to host a successful peregrine nest. Now, state agencies and New Hampshire Audubon work with rock climbing groups to decide when to close cliffs in the summer.  Learn more at BirdNote.org.
