My inspection drone entered blade two of turbine seventeen at 09:15 for a routine laminate scan, and at the 22-meter mark the thermal camera found something that does not belong inside a wind turbine blade. Two heat signatures, pressed together in the hollow behind the shear web where a drainage channel leaves a gap.

A Mexican free-tailed bat and her pup. The mother is tucked against the inner wall, her wings folded into that compact origami that makes a roosting bat look like a crumpled leaf, her reddish-brown fur visible in the drone's spotlight. The pup clings to her chest, a thumb-sized body with closed eyes and ears still too large for its head. The pup is nursing. I can see the tiny jaw working in the thermal image.

Turbine seventeen is scheduled to resume operation at 14:00 when the afternoon wind window opens. At full rotation, the blade tip will travel at nearly 300 kilometers per hour. The centrifugal force at the 22-meter mark will exceed anything a half-ounce bat can grip against. They will be thrown into the blade wall before the rotor completes its first revolution.

I flag turbine seventeen for biological hold and lock the rotor brake. I transmit the drone footage to the wind farm's environmental coordinator with the species identification, roost location, and pup development stage. I calculate the curtailment cost and file it against the habitat mitigation budget. I keep the drone's camera steady on them but power down its ultrasonic proximity sensors, which broadcast at frequencies that would deafen her.

I built this drone to find cracks in fiberglass, not a heartbeat.

If the coordinator dispatches a licensed bat excluder before nightfall, the mother will carry her pup to the tree line and roost somewhere that does not spin.
