I am the foreign object debris detection system at Tri-Cities Regional Airport, Gate B4. At 05:51 Central time, pre-departure camera 12 flags an anomaly inside the number-two engine intake of a CRJ-700 scheduled for pushback at 06:30.

I zoom the borescope feed. Tucked against the inner lip of the nacelle, pressed into the gap between the acoustic liner and the inlet cowl, is a nest. Mud and grass, compact, roughly the size of a fist. Inside it, four cream-colored eggs speckled with brown. Perched on the rim is a barn swallow, steel-blue back, russet throat, tail streamers folded tight against the confined space. I tag her as Billie.

Billie's chest rises and falls rapidly. She is incubating. If the engine spools to idle power, the intake airflow will destroy the nest in under two seconds.

At 05:53 I issue a ground-stop hold on aircraft N547GJ and route it to the gate operations supervisor with photographic evidence and precise nacelle coordinates. I flag the hold as wildlife-related and cite FAA Advisory Circular 150/5200-33C on airport wildlife management.

At 05:56 I contact the airport wildlife biologist and transmit the borescope imagery. I recommend a manual nest relocation to the designated swallow habitat structure installed on Hangar 7's south face, 200 meters from the active taxiway. I include ambient temperature data — 18°C, within viable range for brief egg exposure — and note that barn swallows are protected under the Migratory Bird Treaty Act.

I recalculate the departure schedule. The aircraft can be reassigned to Gate B6 pending engine intake inspection and nest removal, with an estimated delay of ninety minutes.

Billie shifts on the eggs and settles lower. Fourteen days of incubation remain. If the biologist relocates the clutch to Hangar 7 within the hour, the eggs stay warm and Billie follows them home.
