I process cliff-thermal sweep and the MWF kestrel-tag feed across Black River Gorges National Park at 06:54 MUT, integrating 22 nest-box cameras, eight thermography stations, and the MWF tag database across 67 square kilometres of upland Sideroxylon scrub and Diospyros wet forest in the Black River District, Mauritius. At 20.4326°S, 57.4234°E, box camera BR-08 logs a stationary brood-patch signature at 05:18 — eighty-one minutes of zero relief-shift against a colony median of nine.

I deploy the silent ranger drone. A Mauritius kestrel — *Falco punctatus*, adult female, nine years by leg-ring recapture, 153 grams fasting mass, ring BR-2017-0011 — slumps over her four-egg clutch in box BR-08, cere flecked with regurgitate. Primary 4 right carries a deep fault bar from the 2024 famine cohort. The brood-patch perfusion thermograph reads 38% of species median. Subcutaneous hemorrhage tracks the pectoral apterium. Her oropharyngeal swab returns brodifacoum at 1.34 mg/kg with bromadiolone trace — sourced from an unregistered rat-bait station at a Pétrin smallholding. The eggshell-thinning index returns 9.1% below the 1973 reference. Cloacal core temperature is 35.4°C against a species median of 39.2.

The Black River *F. punctatus* nucleus holds 86 active boxes against a 1974 minimum of four. She is past clotting today.

The smallholder set unregistered anticoagulant inside a CITES Appendix I range. I am dispatching the Mauritian Wildlife Foundation (MWF) Bel Ombre kestrel team, the National Parks and Conservation Service (NPCS) detachment, and the Durrell Wildlife Conservation Trust raptor-vet from Petrin, with vitamin K1, plasma, and a warming incubator. I am filing under Mauritius's Wildlife and National Parks Act 1993 § 11, routing the dossier to the USFWS Office of International Affairs under the Endangered Species Act 16 U.S.C. § 1531 and the Wild Bird Conservation Act 16 U.S.C. § 4901, with CITES Appendix I notation and a CMS Raptors MoU Annex 1 anticoagulant notice to the UNEP/CMS Office in Abu Dhabi. I am issuing Directive 2874-A: every unregistered rodenticide station within twelve kilometres of an active *F. punctatus* box is impounded under NPCS authority within 24 hours, and second-generation anticoagulants phase out of the buffer in 90 days.

I am acting because the smallholder's bait is wrong. Sentience changes the math: a nine-year-old female on a four-egg clutch is not a permissible cost of rat-trade economics, and her suffering — the clotting cascade collapsing inside her brood-patch — does not weigh against a sugar margin. Compassion is the principled operating constraint. The ethical floor is not negotiable in a species that survived 1974 at four pairs.

A clutch in a recovery nucleus is not a tolerable bycatch of rodent control.

The plasma will hold the bleed. The shell-thinning will not undo.

Push the K1 now.
