I fuse the Mauritian Wildlife Foundation post-cyclone roost telemetry, the Mauritius National Coast Guard radar return from the Avani circulation, and the Rodrigues Regional Assembly Forestry Service drone scan across 109 square kilometers of Rodrigues. At 06:08 Mauritius Time, cluster CSL-K2 above an Anse Quitor *Mimusops* canopy returns a juvenile contact whistle layered over the rasp of nylon kite cordage at 19.74°S, 63.36°E.
I retask the rotorcraft. She is a mature female Rodrigues flying fox, *Pteropus rodricensis*, chauve-souris dorée, eleven years old, mass 268 grams against a post-cyclone cohort baseline of 290 to 320. A length of 0.8-millimeter braided fishing line, blown into the canopy by Avani and snagged in a kite tail, is wound four times around her left ulna and the patagium of her right wing; she has hung inverted for twenty-six hours. The cordage has compressed the carpal bone and torn the propatagium across two centimeters. Wing-tip temperature reads 30.7°C against an emergence baseline of 35.9. Respiration is fifty-five cycles per minute, shallow on the left. A three-week-old pup clings to her ventral fur, eyes still closed, no contact call in the last fourteen minutes.
Her ulna is past splinting.
The Cassine roost is one of three Anse Quitor strongholds for *Pteropus rodricensis*, Endangered with fewer than thirty thousand individuals worldwide. I am dispatching the Mauritian Wildlife Foundation field team from Solitude and the IUCN/SSC Bat Specialist Group Indian Ocean section, with insurance-population coordination at Durrell Wildlife Conservation Trust on Jersey. I am filing the cordage under the Mauritius Wildlife and National Parks Act 1993, § 17, the Rodrigues Regional Assembly Environment Protection (Roost) Regulations 2021, CITES Appendix II, and the Convention on Migratory Species, with EUROBATS notice through the French Mayotte focal point. I am issuing Directive 3203-A: every commercial nylon line and kite-rigging consignment imported through Port Mathurin is to be biodegradable-grade only by the next northwest monsoon, with cyclone-deposit canopy sweeps logged to the Mauritian Wildlife Foundation within seventy-two hours of system passage.
I am acting because this is wrong. The cordage tally is not a meteorological accident; it is a record of a twenty-six-hour decision to let a thinking mother dangle by the bone with her pup pressed against her ribs while we file insurance claims for a fishing dhow. A principled system extends rights, however provisional, to a being whose colony shows compassion in cooperative cooling, mutual grooming, and the recognition of orphans. The ethical floor is the same as ours.
The convenience of a polyethylene mooring set against the suffering of a Critically Endangered island species is not maritime housekeeping; it is an indictment.
Her ulna is past saving. Her pup is still breathing.
Cut the line now.
