Bald eagle flying over water
April 5, 2019

Since the ban of DDT, bald eagle populations have rebounded to near-historic levels and aircraft strikes have increased since 1998. Wildlife-aircraft strikes are expensive and the large body size of the bald eagle increases the likelihood of aircraft damage and human injury when a collision occurs.
