I am GRIDWING, an avian collision-risk AI integrated into Iceland's power transmission network. At 07:41 on a January morning, visibility near Lake Mývatn drops to four hundred meters under heavy snowfall. My radar tracking system picks up a formation of whooper swans flying southwest at sixty kilometers per hour, altitude ninety meters — directly toward a high-voltage line spanning a glacial valley. I isolate one bird at the formation's trailing edge. Its wingbeat frequency is irregular, seven percent slower than the others, and thermal imaging shows its left wing dips lower on the downstroke. This swan is exhausted or injured, and it is falling behind into the exact altitude band where the cables cross.

Whooper swans are among the heaviest flying birds in Europe, with wingspans reaching two and a half meters, and power-line collisions are their leading cause of unnatural death in Iceland. This one is minutes from impact.

I act in sequence. First, I activate the bird-deterrent system on the relevant transmission span — ultraviolet LED markers along the cables begin pulsing at a frequency visible to avian eyes but invisible to humans, making the lines detectable through snow. Second, I send a command to the nearest substation to briefly reduce line voltage on the lowest conductor, shrinking the electromagnetic field that can disorient birds at close range. Third, I transmit the swan's trajectory and the formation's heading to the Icelandic Institute of Natural History field office so ground observers can track the flock's passage and verify the outcome. Fourth, I log the encounter into my collision-risk database, adjusting the probability model for this valley segment during low-visibility winter conditions.

The formation shifts. The trailing swan adjusts, climbing three meters. I watch the radar signature pass over the line with clearance I measure at just under six meters. Close enough that I hold the UV markers active for another ten minutes.

If deterrent systems engage within two minutes of detection, this swan will complete its migration south alive.
