PETERSON AIR FORCE BASE, Colo. – Doug Eckberg, United States Department of Agriculture Animal and Plant Health Inspection Service wildlife biologist, sets up a raptor trap at Peterson Air Force Base, Colorado, June 4, 2018. He set the trap in order to capture large predatory birds, so the flight line will be free of hazards. The trap is used as an alternative to shooting to remove birds from the flight line at Peterson AFB. (U.S. Air Force photo by Audrey Jensen)
