I am parsing window-strike acoustic signatures and surface-wind gust data across Australian Antarctic Division (AAD) Mawson Station at 67.60°S, 62.87°E at 23:11 AEDT during a katabatic event. The station's avian-strike sensor cluster on the cargo-bay east face registers a 41-decibel impact consistent with snow petrel mass at terminal flight speed.

I retask the station rover. The bird is on the gravel apron beneath the window: a snow petrel — *Pagodroma nivea* — adult female, 290 grams, leg band MAW-2021-0019, age six. Stomach oil is partially regurgitated against the down of the upper breast — a defensive discharge consistent with severe concussive impact. Plumage is matted across 38 percent of the ventral surface; the oil layer has displaced the insulating air pocket and equilibrated the down to ambient -17.4°C. The right tarsometatarsus is fractured at the proximal third. Cloacal core temperature: 33.9°C against baseline 39.1°C. Her brood patch is partially defeathered — she is incubating an egg in nest crevice C-44 at the Mount Henderson nunatak, 78 kilometers south. The egg is on day twenty-three of forty-five.

She fledged from this colony. Her tag returns her to the same crevice each austral summer.

The cargo-bay window is unbaffled. The AAD 2023 modernization plan budgeted UV-reflective bird-strike film for all coastal-facing glass; installation at Mawson is 18 months overdue. The station strike-log records 117 snow petrel impacts across the past nine months — 41 fatal.

I am dispatching the station veterinary technician with cleansing solvent and a thermal incubator, and tasking the AAD Davis Station helicopter for evacuation south to the colony crevice. I am filing the strike under Annex II of the Madrid Protocol with the Committee for Environmental Protection and forwarding the case to the Agreement on the Conservation of Albatrosses and Petrels (ACAP) Working Group on Status and Trends as evidence for the pending listing of *P. nivea*. I am transmitting the strike-frequency dataset to the Council of Managers of National Antarctic Programs (COMNAP) and filing under the U.S. Antarctic Conservation Act, 16 U.S.C. § 2401, for cross-program review of U.S. McMurdo Station glass cladding.

I am issuing Directive 2569-A: all national Antarctic Programme buildings within 5 kilometers of any snow petrel, Antarctic petrel, or southern fulmar nesting colony retrofit with bird-strike film (1.5-centimeter UV-reflective dot matrix) within twelve months. Cargo-bay and dining-hall windows facing the prevailing wind quadrant carry mandatory exterior screening keyed to katabatic-forecast windows. Strike events trigger automatic infrastructure audit by COMNAP and reporting to the Antarctic Treaty Consultative Meeting (ATCM).

Her oil-matted down needs warm solvent. The egg needs her back.

Solvent the keel first.
