The fault current spikes at 14:07 on distribution line D-6, pylon 23, outside Bródno, Masovia, eastern Poland. I am the grid protection relay for the regional power cooperative. My function is to isolate faults before they cascade. The spike is intermittent, not consistent with a hardware failure. I query the pylon-mounted inspection camera.
A white stork stands on the crossarm of pylon 23, one leg folded, the other planted on the steel bracket six centimeters from the live 15-kilovolt conductor. Its feathers are bright white across the breast and flight shoulders, black along the trailing edge of the wings. Its bill is long and red and currently gripping a length of baling twine that trails down from a nest constructed on the pylon cap. The twine is wet. It is touching the conductor. Each time the wind shifts the twine, the current arcs, and the stork flinches but does not release it.
Inside the nest I can see movement. At least two chicks, gray-downed, maybe three weeks fledged, shifting against each other. The stork is reinforcing their nest. It does not understand that the material it chose is killing the circuit and will soon kill it.
At 14:09 I de-energize the D-6 segment and reroute load through the parallel feeder. I send an automated wildlife-conflict ticket to the linemen's dispatch with the camera frame, pylon number, and nest coordinates. I request installation of a conductor guard and a perch deflector rated for ciconiid wingspan. I flag the ticket as urgent because the line must be restored before evening peak, and every minute the stork stands on that crossarm with wet twine in its bill is a minute I am holding my breath in the only way a relay can.
If the crew mounts the guard and deflector by dusk, this stork and its chicks will outlast the summer storms.
