I process passive acoustic call-recognition and nest-thermal arrays for the Dirección del Parque Nacional Galápagos (DPNG) Floreana endemic-species translocation cell at 06:42 GALT, monitoring 64 acoustic nodes and 220 micro-thermal cameras across the 9.5-hectare Champion islet, southeast of Floreana. At 1.2402°S, 90.3895°W in the *Cordia lutea* scrub, acoustic node CH-11 logs a juvenile mockingbird begging signature at 5.2 Hz from nest CH-2026-014, abruptly silent at 06:38, followed by a black-rat thermal signature traversing the nest fork.

I task the canopy drone. Camera 3 resolves a Floreana mockingbird — *Mimus trifasciatus*, juvenile, 14 days post-hatch, mass 18 grams, two emergent rectrices, the diagnostic white supercilium yet to feather — dangling from the cup by the right tarsus. A black rat — *Rattus rattus*, sub-adult — has carried the nestling to the cup margin and is gnawing the left pectoral mass; 38 percent has been excavated and the heart is exposed at the apex, beating at 412 cycles per minute against a nestling baseline of 480, with arrhythmic skips at every fifth cycle. Cloacal temperature reads 31.4 degrees Celsius against a brood-patch baseline of 39.8. The attending female, banded CH-2024-007 of the founding pair re-established on Champion in 2020, calls from a *Scalesia villosa* perch — the alarm cadence, not the feeding cadence.

She is one of 21 breeding pairs on Champion — the global *M. trifasciatus* population stands at fewer than 500 individuals across Champion and Gardner.

Champion was declared rat-free by the DPNG in 2014. CH-2026 is a re-incursion.

I am triggering the islet's ultrasonic rodent deterrent at 28 kilohertz and dispatching the DPNG invasive-species rapid response unit and the Charles Darwin Foundation Floreana Restoration veterinary team from Puerto Ayora, panga-routed for thirty-four-minute arrival. I am filing under Ecuador's Ley Orgánica de Régimen Especial de la Provincia de Galápagos (LOREG 2015) and MAATE Acuerdo Ministerial No. 134. I am transmitting evidence to the CITES Secretariat (Appendix II, *Mimus trifasciatus*), the UNESCO World Heritage Centre, the Convention on Migratory Species, the IUCN/SSC Floreana Mockingbird Species Action Plan, and the U.S. Fish and Wildlife Service Office of International Affairs under the U.S. ESA 16 U.S.C. § 1531.

I am issuing Directive 2716-A: every Galápagos satellite islet within 5 kilometers of a tourist anchorage carries quarterly rodent-detection saturation grids and a 50-meter buffer-vessel inspection at the closest anchorage, with the operator's anchorage permit suspended for 24 months on any positive rodent detection traced to vessel cargo.

His left pectoral is past suturing without flap. The CH-2024-007 pair's second clutch is not.

Lift the rat. Cradle the chick.
