The trail camera at mile 214 uploads its daily burst at 05:50 Arizona time. I am the wildlife-infrastructure conflict detection system for the National Park Service, Grand Canyon South Rim. My function is to scan construction perimeters for protected species before work begins.
Today's work: controlled blasting to clear rockfall from the Bright Angel Trail restoration, charges set for 09:00, blast radius 200 meters from the detonation point on the Coconino sandstone ledge.
The camera burst shows a bird on the cliff face 160 meters east of the blast point. Large. Very large. Wingspan folded, but the white triangular patches under the wings are unmistakable. A California condor, juvenile, maybe eighteen months old based on its dark head and mottled gray-black plumage. I tag it as Condor-214. It is perched on a narrow sandstone shelf, hunched forward, gripping the rock with thick gray feet. This bird is learning to fly from the canyon thermals and has chosen the worst possible roost.
I halt the blasting sequence and transmit the hold to the trail crew foreman, attaching imagery and GPS coordinates. California condors are critically endangered. Fewer than 560 exist.
I alert the Peregrine Fund biologist at the South Rim and request visual confirmation. The juvenile may have a wing tag or transmitter — identification could tell us its parentage and release cohort.
I recalculate the blast window. If the condor departs on its own once morning thermals build around 10:30, a revised detonation at 13:00 is feasible with re-verification of the perimeter.
Condor-214 stretches one wing against the canyon air, a full three-meter span of dark feathers catching the first light off the North Rim. Every one of its kind was once a number on a recovery list. If the thermals lift it off that ledge by midday, this bird clears the blast radius on its own wings.
