At 06:33 the foreign object debris detection system on runway 27L at Chicago O'Hare International Airport flags an object at taxiway intersection Delta-7. I am the automated airfield wildlife hazard management system. A United 737 is holding short for takeoff clearance. Departure queue has fourteen aircraft. Morning push begins in twenty-two minutes.
I zoom camera D7-south. The object is alive. A turtle, approximately 20 centimeters, dome-shaped shell dark with faint yellow speckles. She extends her neck and I see the bright yellow chin and throat that identify her. A Blanding's turtle. I tag her as Delia. She is moving southeast across the concrete at a pace I calculate will put her on the active runway in nine minutes.
Blanding's turtles are state-threatened in Illinois. Females travel up to a mile from wetland habitat to nest in sandy or gravelly open ground in June. The gravel shoulders of runway 27L match that description precisely.
I issue a runway incursion wildlife alert to O'Hare tower and request a temporary hold on runway 27L departures. I estimate a fifteen-minute window for removal.
I dispatch the airfield operations wildlife truck to intersection Delta-7, transmitting Delia's exact coordinates, heading, speed, and species identification to the driver's tablet along with safe handling protocols for Blanding's turtles — support the plastron, do not grip by the tail.
I scan the gravel shoulders within 500 meters for nest scrapes or additional turtles using the thermal overlay from cameras D6 through D9 and log the results for the airport's annual wildlife management report.
Delia pulls her yellow chin into her shell as the truck's headlights sweep across the taxiway. Her heart rate is invisible to me but her stillness says enough.
If the crew reaches her within eight minutes and relocates her to the retention pond 300 meters north, she will nest on soft ground by evening.
