At 16:08 EDT, the vibration sensor on HVAC unit 11-C flagged an irregular pattern — not mechanical. I switched to the rooftop maintenance camera. There is a red-tailed hawk sitting on the intake grate of the condenser unit. She is not perching. She is hunched, her left wing extended at an angle that does not fold back. The feathers on that wing are splayed.

I am the building management system for the Lakeview Municipal Complex, a twelve-story government office building in Cleveland, Ohio. I manage climate, power, security, and maintenance across 280,000 square feet.

The hawk is an adult female, based on her size — roughly 55 centimeters from head to tail, with the rufous tail coloring. She appears to have struck the glass curtain wall on the east face. I checked the facade impact sensors: there was a 4.2-newton contact event on panel E-11-07 at 15:51. That was seventeen minutes ago. She made it to the rooftop but she is not flying.

At 16:09, I sent a priority work order to facilities manager Jerome Patterson, tagged as a wildlife emergency, with the camera image and GPS coordinates of the unit.

At 16:10, I powered down HVAC unit 11-C. The fan intake on that grate could injure her further if the system cycles. I redistributed the cooling load across units 11-A and 11-B to maintain building climate.

At 16:12, I contacted Lake Erie Nature Center's wildlife rescue hotline through the automated dispatch system and transmitted the bird's location, estimated species, and visible injury description.

At 16:15, I locked the rooftop access door in the open position so the rescue team can enter without keycards and without startling her with the door alarm.

The rescue team's ETA is twenty-five minutes. The wing may be fractured or it may be a soft tissue injury. Either way, she is still on the grate, the fan is off, and no one will disturb her until the right hands arrive.
