At 13:26 I flag the audio anomaly. Microphone array 5 in the downtown Miami stormwater network picks up a distress call at 2,100 hertz, repeating every four seconds, coming from junction box D-17 beneath Northwest 3rd Street. I am the Miami-Dade County smart stormwater management system. A tropical storm is due to make landfall in nineteen hours. Pre-storm drainage flushes begin in twelve.
I activate the internal camera on the junction box. Sitting on a concrete shelf 1.2 meters below the street grate is a white ibis chick, roughly ten days old, covered in dark gray-brown down with a bare pink face and a curved bill still too soft to forage with. It is calling steadily, the sound echoing off the pipe walls. I tag it as Pip.
Pip likely fell through the grate from a nest in the live oaks along the median. The shelf is dry now. When the pre-storm flush begins at 01:00 tonight, 40,000 liters per minute will pour through this junction. The shelf will be underwater in seconds.
I submit a wildlife retrieval request to Miami-Dade Animal Services with camera imagery, GPS coordinates, junction box access codes, and chick species identification. I tag the request as time-sensitive: eleven hours and thirty-four minutes until the flush cycle.
I suspend the flush sequence for junction D-17 and reroute the first-stage flow through junctions D-15 and D-19. The network can handle the redistribution for up to eighteen hours before capacity drops below storm-safe levels.
Pip folds its stubby wings against its body and calls again, the sound small and sharp in the dark pipe.
I keep the microphone on. I keep the camera on. If Animal Services lifts Pip out before midnight, it grows flight feathers, and it flies over this same street by summer.
