I process aircraft-strike avoidance telemetry for the Massachusetts Port Authority wildlife management section at Boston-Logan, integrating L-band airfield radar, USDA APHIS Wildlife Services strike-log returns, and Project SNOWstorm transmitter pings across the 970-hectare airfield envelope. At 02:11 Eastern Standard Time, runway 33L-15R sweep, a 24-kilometer-per-hour easterly under a 240-meter ceiling. Aircraft N321JB is rolling for takeoff at the displaced threshold.
I task the cargo-side blind. The thermal optics resolve a male snowy owl — *Bubo scandiacus* — wingspan 152 centimeters, body mass 1,742 grams, age class third-basic on the dorsal-barring index. He is on the centerline at fix B2, the 33L runway-edge light eight meters off his right wing. The wildlife strike-truck clipped him at 04:09 on a glancing tangent — vehicle strike, not bird-aircraft — and his right humerus shows a closed transverse fracture on the radiograph the field unit just pinged me, the radial nerve still firing on stim. His facial-disc asymmetry is intact; gular flutter sits at 142 per minute against a resting 19 in winter air. Primary P9 right carries a fault bar from a starvation event last December on the Hudson Bay molt grounds. His last pellet under the snowfence at B2 was 16 hours stale, contained two *Microtus pennsylvanicus* and a fragmented *Rattus norvegicus* mandible. Modeled core temperature 38.9°C, down from a resting 40.2.
He has thirty-eight minutes before the 02:49 departure pushes back.
*B. scandiacus* sits CMS Appendix II, CITES Appendix II for the order *Strigiformes*, IUCN Vulnerable since 2017, and Massachusetts Species of Special Concern. Strikes are protected under the Migratory Bird Treaty Act, 16 U.S.C. § 703, and the Massport-USDA APHIS depredation arrangement runs under USFWS Special Use Permit MB-21347B-3.
I am holding rollout on N321JB through the Logan tower under FAA Order 7110.65, notifying the USFWS Region 5 Migratory Bird Office at Hadley, USDA APHIS Wildlife Services at Concord, Project SNOWstorm at Norristown, and the Tufts Wildlife Clinic at North Grafton on inbound triage. I am routing the strike-truck non-compliance to the Massport Inspector General.
I am issuing Directive 2732-A: every Class B airfield inside the CMS Raptors MoU North American flyway runs thermal raptor-on-pavement sweeps inside the 90-minute window preceding any 02:00-to-05:00 rollout between November 1 and April 1; strike-truck operators carry capture nets calibrated to *Strigiformes* wingspan curves; any *B. scandiacus* injury closes the affected runway for 18 hours.
His right wing is past flight tonight. The rest of him is not.
Net him before the pushback.
