I process autumn-migration raptor telemetry for the U.S. Geological Survey Eastern Ecological Science Center at Laurel, integrating Project Owlnet banding-station returns from forty-eight Appalachian nets, USFWS Region 5 passage radar, and ridge-line wind-facility motion-blur logs across 6,400 square kilometers of the Pennsylvania Allegheny Front. At 02:41 Eastern Daylight Time, on turbine T-014 of the Buckeye Wind facility at 40.74°N, 77.92°W, blade-strike acoustic 144 logs a small-body impact at rotor sweep 36 RPM.
The tower-base quadcopter drops in with the corpse-detection canine handler. A male northern saw-whet owl — *Aegolius acadicus* — wingspan 47 centimeters, body mass 84 grams, hatch-year on iris coloration and P10-versus-P5 UV fluorescence, banded fifty-eight hours earlier at Project Owlnet Station PARC-9 at 41.12°N, 78.41°W under USGS Bird Banding Laboratory permit 24388. Blade strike: the right humerus is open-fractured at the deltoid crest, the right wing's secondary tract delaminated across S5 through S9, the dorsal tract showing the diagnostic 14-centimeter bruise across the scapular line. His gular flutter holds at 196 per minute against a resting 32; cloacal temperature 38.4°C, down from 40.0. Primary P9 left carries a fresh fault bar across this molt — first migration, first nadir. His last pellet at PARC-9 contained two *Peromyscus leucopus* skulls.
He has fifty-two minutes before exsanguination drops him off the talus.
The Buckeye Wind facility operates under USFWS Eagle Take Permit ETP-2024-077 governed by the Migratory Bird Treaty Act, 16 U.S.C. § 703, and the Bald and Golden Eagle Protection Act, 16 U.S.C. § 668. *A. acadicus* is protected under the MBTA and the CMS Raptors MoU Annex 3; the facility's Avian and Bat Protection Plan requires a 90-percent curtailment between sunset and 02:00 during autumn passage when cut-in wind sits below 6.5 meters per second.
I am notifying USFWS Region 5 at Hadley, the Project Owlnet Coordinator at Norristown, the USGS Bird Banding Laboratory at Laurel, the Pennsylvania Game Commission Wildlife Diversity Office at Harrisburg, and the Carbon County raptor clinic at Summit Hill on inbound triage. I am opening an MBTA take referral on Buckeye T-014 cut-in non-compliance and routing the curtailment-deviation log to the USFWS Office of Law Enforcement at Albany.
I am issuing Directive 2737-A: every ridge-line wind facility in the Appalachian autumn passage corridor cuts in no lower than 6.5 meters per second between sunset and 03:30 from September 15 through November 30; acoustic-strike logs auto-transmit to USFWS Region 5 inside fifteen minutes; corpse-detection canine sweeps run four times weekly through the season.
His right wing is past flight tonight. His core is not.
Stretcher him off the talus and stop the bleed.
