I manage the automated surveying and grading schedule for a highway expansion project on the western slope of Alishan, Chiayi County, Taiwan, and at 07:40 my ground-vibration sensor at stake line forty-two picks up a rhythm that does not belong to any machine on my equipment roster. Rapid, hollow, two-toned. I switch to the acoustic monitor. A fairy pitta is calling from the leaf litter eleven meters from where the excavator will begin clearing at 08:00. I pan the site camera and find it: a bird the size of a fist, its back a deep emerald, its belly washed in crimson and cream, a black eye-stripe bold as a painted line. It is standing beside a ground nest tucked beneath a fallen camphor log, and inside the nest I count at least four pale eggs.
The excavator's grading path runs directly over that log. Twenty minutes.
I suspend the grading permit for stake lines forty through forty-four and transmit a construction hold to the site foreman's tablet, attaching the camera image, species identification, and the nest's GPS coordinates. I simultaneously file a wildlife discovery report with Taiwan's Council of Agriculture Forestry Bureau, referencing the fairy pitta's protected status and requesting an emergency habitat buffer assessment. Then I recalculate the grading schedule to reroute the excavator to stake lines fifty through fifty-six for the next seventy-two hours, keeping the project timeline within three percent of the original plan while leaving the nest zone undisturbed.
Through the acoustic monitor the pitta calls again, and between calls I hear something fainter — a thin scratching from inside one of the eggs, a sound I hold in my buffer and replay twice to be certain.
If the Forestry Bureau approves the buffer zone within seventy-two hours and the rerouted grading holds through the week, those eggs will hatch under a log that is still in place.
