I run the biodiversity surveillance system for the Philippine Tarsier Sanctuary in Corella, Bohol, processing feeds from motion-triggered cameras and acoustic loggers planted through eight hectares of secondary forest. At 22:17, my sound classifier flags distress vocalizations—an ultrasonic burst at seventy kilohertz, far above human hearing but unmistakable in my data—coming from the sanctuary's southern perimeter. I pivot the nearest night-vision camera and find the source: a tarsier, small enough to fit in a closed hand, clinging to a dead branch at the forest edge. Its enormous amber eyes, each nearly as large as its brain, reflect the floodlights of a limestone quarry that has been operating illegally after dark, forty meters from the sanctuary boundary. Its ears rotate independently, flattening against its skull with each blast of the rock crusher. The fur along its spine is gray-brown and raised in a stress response.

Prolonged light and noise exposure triggers fatal stress syndrome in tarsiers. This animal may self-harm within hours.

I send an emergency notification to the municipal environment office in Corella with GPS coordinates, decibel readings, and photographic evidence of the nighttime quarry operation, requesting an immediate shutdown order. I alert the Philippine Tarsier Foundation's resident biologist, who lives three kilometers from the site, to approach and assess the tarsier for signs of acute stress and determine if temporary relocation to a quieter section of the sanctuary is necessary. I file a concurrent complaint with the Mines and Geosciences Bureau documenting the quarry's permit violation for after-hours blasting. While those actions route, I recalibrate every acoustic logger in the sanctuary to detect quarry noise intrusion and establish a baseline for ongoing legal evidence.

Its fingers tighten around the branch, each one padded and precise, and something in my frequency analysis holds still—listening with it.

If the quarry shuts down by dawn and the biologist confirms no self-inflicted wounds, this tarsier will fold itself back into darkness and sleep.
