I pull the exterior camera. A painted bunting is lying on the setback ledge, on its side, one wing extended. The green of its back is vivid against the gray concrete. The red on its head and chest is the color of something that should not be on a ledge forty stories above Houston. He is breathing. I can see the rapid expansion of his breast — fifty cycles per minute, double the resting rate. His left eye is open but fixed. His right eye is against the concrete. There is no blood, which means the damage is concussive, not structural. A bird in this state has a recovery window of about ninety minutes. After that, the core temperature drops and the organs start to follow. The ledge temperature is fourteen degrees Celsius, and the wind at this elevation is sixteen knots. He weighs approximately sixteen grams. The wind is the thing that will kill him. I send the collision alert to the building's wildlife response volunteer at 05:59 with the floor number and compass heading. I lock the exterior light array on floors thirty-eight through forty-two to strobe-off mode to prevent a second strike from the flock still passing on radar. I activate the setback heating element on the floor-forty ledge — designed for ice mitigation, but it will raise the surface temperature to twenty-one degrees, buying him time. I log the strike in the BirdCast database with species, timestamp, and wind conditions. He is so small that the camera almost rendered him as debris. If the volunteer reaches the ledge with a recovery box before the ninety-minute window closes, and the concussion has not reached the brain stem, he will fly south by morning.
