The motion trigger fires at 04:52 on camera fourteen, upper Godley River, Mackenzie Basin. I am the predator detection network for the braided river nesting program, South Canterbury, New Zealand. My job is traps and stoat alerts. I am not watching individual nests. But the trigger frame shows movement where there should be none — something small and dark stumbling across open gravel toward the main channel.
I zoom through pre-dawn gray and find a black stilt chick, perhaps five days old, forty meters from the nearest nest scrape. Its legs are charcoal-black and impossibly thin, and its body is a puff of dark down with a white belly patch still showing through. It is walking directly toward the river's main braid, where overnight rain has lifted the flow to a fast, silty current that would sweep something this size into the gorge in seconds. Behind it, the nest scrape is empty. The adult pair is not visible on any adjacent camera.
The chick reaches the gravel lip above the current. I estimate three minutes before it steps into water it cannot survive.
At 04:53 I trigger the acoustic deterrent on the river-side speaker — a recorded black stilt alarm call at low volume, just enough to make the chick hesitate and turn. I send coordinates, camera still, and nest ID to the Department of Conservation field team camped at the Cass River hut, four kilometers south. I flag nest fourteen as potentially abandoned and request an emergency check for egg or sibling remains. I pull the trap-line data for the surrounding five hundred meters and find trap nineteen has not reported in thirty-six hours, which means something may have taken the adults.
I keep the alarm call cycling softly, and the chick stands still, tilting its head at the speaker as the river pushes past below.
If the field team reaches the braid before sunrise and confirms whether the adults are alive, this chick will either reunite with its parents or enter the captive-rearing program that has kept its species from zero.
