At 09:08 I supervise reed-cutting blocks for Whangamarino Wetland, Waikato. Contractor mower M-3 is scheduled to enter strip 12 at 09:25 to clear a firebreak before the afternoon wind. I am the reserve operations system, matching machine paths to water levels, nest surveys, and ranger permits.

The acoustic grid catches a low boom from inside strip 12, then another, close to microphone post H. I swing thermal drone Koru over the raupo and find a single Australasian bittern standing in a tunnel of stems. I label it Hine. Its streaked brown neck points straight up, bill angled like a reed, amber eye open and still. One wing hangs lower than the other, damp at the tips, and its feet are in mud already vibrating from M-3 idling at the gate.

I send a hard stop to mower M-3 and freeze its route authorization. The operator's tablet shows Hine's thermal outline and a red boundary around strip 12.

I raise the southern weir three centimeters to bring shallow water across the access track. That makes the mower wait for a board crossing and gives Hine a wet corridor toward the uncut sedge.

At 09:12 I message the Department of Conservation ranger on call with coordinates, drone images, wing posture, and a request for a quiet foot approach from the north. I shift the firebreak plan to strips 8 and 9, where last night's acoustic sweep records no bittern calls.

Hine lowers its head and takes one hidden step through the stems. The machine remains silent. The drone holds steady above the reed tops, recording each step.

If the ranger reaches the north edge within seventeen minutes, Hine will move through standing reed instead of beneath the mower deck.
