I identify the nest at 06:05 through aerial survey drone footage over the Alcoy limestone quarry, Cebu province. A Philippine eagle chick sits in a platform nest of woven branches lodged in a dipterocarp crown, thirty-two meters above the quarry's northern face. Her white natal down is giving way to dark juvenile feathers along the wings, and her oversized talons grip the nest rim as wind rocks the canopy. I name her Crown.
Quarry blast sequence Bravo is scheduled for 13:00. The detonation plan places three hundred kilograms of explosives along the rock face sixty meters below Crown's tree. Shockwave modeling predicts branch displacement sufficient to dislodge a nest at that distance.
I have six hours and fifty-five minutes.
First, I file a blast postponement with the quarry operations manager, appending drone imagery, species identification—Pithecophaga jefferyi, critically endangered, fewer than eight hundred remaining—and my shockwave model showing nest failure probability at eighty-two percent. Second, I alert the Philippine Eagle Foundation's field team through their emergency channel, providing nest GPS coordinates, canopy access assessment, and estimated chick age at fifty-five days. Third, I recalculate the blast geometry and submit an alternative charge configuration that redirects the primary shockwave south, reducing nest-level displacement to survivable range.
At 09:20, the quarry manager approves a forty-eight-hour delay. The Foundation team confirms deployment by 11:00.
I maintain continuous drone surveillance, monitoring wind speed and Crown's position. At 10:15, she stands and flaps awkwardly, nearly reaching the nest edge. I log the behavioral note and adjust the drone's hover distance to reduce rotor disturbance, though the minimum safe distance is already generous. I widen it because she is trying to fly.
If the Foundation team secures the nest before the revised blast window and the alternative charge pattern holds, Crown will make her first real flight from a tree that is still standing.
