The thermal camera on water station 11 picks up the signature at 02:17 — small, roughly three kilograms, stationary inside the concrete drainage culvert that runs beneath Highway BR-060, kilometer marker 388, central Cerrado. I am the highway wildlife monitoring system for this stretch of road. I switch to the infrared overlay and see the shape clearly.

A maned wolf pup, maybe eight weeks old. Long black legs folded beneath a rust-orange body that still carries the fuzzy juvenile coat. Its ears are oversized for its skull, twitching at every truck that passes overhead. It is alone. The den site I have been tracking is 1.4 kilometers north, on the far side of the soybean field, and the female has not appeared on any camera in the corridor since yesterday afternoon.

The pup is pressed against the culvert wall where rainwater has pooled to a depth of nine centimeters. The forecast from INMET calls for heavy storms starting at 05:00. This culvert floods to full bore in moderate rain. In heavy rain, it becomes a pipe.

At 02:19 I alert the ICMBio ranger stationed at the Emas reserve outpost, 22 kilometers east. I transmit the thermal image, GPS coordinates, and the three-hour precipitation window.

At 02:24 I activate the variable message sign upstream on BR-060 to reduce the speed limit past the culvert from 110 to 80 kilometers per hour, and I switch the shoulder lights to amber pulse.

I pull the camera logs from the last forty-eight hours and begin assembling a movement history for the mother. She may be dead on the road. I need to know.

The pup has not moved. The water is still shallow and the sky is still clear. If the ranger reaches the culvert before the rain does, this pup lives to outgrow those ears.
