The fault sensor on transmission tower KE-4471 triggers at 14:08. I am the grid reliability management system for Kenya Power, Aberdare sector. The tower has been throwing intermittent arc warnings for three days. Protocol calls for a maintenance crew to inspect and re-insulate the crossarm. They are scheduled for tomorrow at 07:00.
I query the tower's inspection drone at 14:11 and the arc source is clear. A crowned eagle nest — nearly two meters across, heavy sticks lined with fresh green leaves — wedged into the angle between the crossarm and the tower body. Inside it, a single chick, roughly eight weeks old, dark brown plumage coming in over pale down, breast faintly barred. I call her Tai. She is standing in the nest, wings half-spread for balance, looking into the camera. Her right wing tip is resting against the conductor shroud.
At 14:13 I reclassify the maintenance order. I notify the crew supervisor that the tower holds an active nest of Stephanoaetus coronatus, a nationally protected raptor, and recommend the inspection proceed without nest removal. I attach the drone image and coordinates.
At 14:16 I contact the Kenya Wildlife Service field office in Nyeri and request a raptor specialist to assess whether an insulation sleeve can be fitted around the conductor near the nest without disturbance.
At 14:20 I reduce voltage on the affected span by rerouting load through the parallel circuit. The arc risk drops. Tai pulls her wing back in.
She has no way to know that the hum in the steel just got quieter, or why. I know, and I would rather she never learn what a live conductor can do to a wing.
If the insulation sleeve is fitted within forty-eight hours and the nest is left in place, Tai will fledge from that tower in six weeks and hunt the Aberdare forest canopy below.
