Jens Fleer, 52nd Fighter Wing base falconer, swings a lure to retrieve his hawk at Spangdahlem Air Base, Germany, Jan. 16, 2019. Fleer uses birds of prey to catch pests, such as crows, to keep air space clear so aircraft can safely fly. The lure is made with a crow wing to help attract and train with the hawk.
