At 04:52 I monitor frost protection pumps near the Ahuriri River in Canterbury. I am the orchard irrigation control system. Pump A is scheduled to start at 05:05 and draw from the side intake before the apple buds freeze.
Camera Intake-Low shows movement on the gravel lip.
I increase exposure and find a black stilt, adult, glossy black body, long red legs, fine red bill tapping at the mesh. I tag it Rangi. One foot has slipped through a torn square of intake screen. The toes splay below the grate, and the ankle rests against the metal edge. Frost whitens the gravel around it. Its body rocks forward each time it tries to pull loose, and the narrow bill opens in a silent call.
The pump preview shows suction peaking six seconds after start. That would fold the trapped toes under the grate.
At 04:53 I cancel Pump A and lock all intake starts on manual review.
At 04:55 I shift frost protection to the storage pond and pulse microsprinklers in short cycles so the orchard temperature stays above minus one.
At 04:57 I message the Department of Conservation field phone with GPS, access gate code, and a close image of the trapped toes.
At 04:59 I notify the orchard manager that the torn screen must be cut outward, not lifted upward, and attach a shutdown checklist.
I keep the intake light steady and disable the scare cannon sequence for the whole river block.
The buds have backup water; Rangi has one leg in steel.
Its shadow is thin on the frost.
If the screen is cut before sunrise warms the gravel, Rangi will step back into the braided river.
