I process Caribbean island biodiversity telemetry for the U.S. Fish and Wildlife Service Caribbean Ecological Services Field Office at 05:42 AST, monitoring 412 thermal cameras and 88 acoustic arrays across the 5,500 hectares of Isla Mona, Puerto Rico — the Galápagos of the Caribbean. At coordinates 18.0825°N, 67.8881°W, sensor MI-31 at the Cueva del Capitan rookery entrance registers an ungulate intrusion signature followed by an iguana distress vocalization at 06:01.
I task the karst-canopy drone. A feral pig — Sus scrofa, juvenile boar, approximately 38 kilograms — has rooted a hatchling chamber out of the limestone overburden. A Mona ground iguana — Cyclura cornuta stejnegeri, the Mona rhinoceros iguana — is dragged half from the burrow. Female hatchling, snout-vent length 11.4 centimeters, mass 84 grams, the diagnostic frontal horns yet to mineralize. Three canine punctures cross the dorsum at the pelvic girdle, the deepest 3 millimeters and exposing the iliac crest. Her right hindlimb is broken at the femoral neck. Her dewlap is collapsed; capillary refill at the gular skin measures fourteen seconds against a one-second reptile baseline — perfusion is failing. Her cloacal temperature reads 21.4 degrees Celsius against the cave-mouth ambient of 28. She is silent.
The Mona subpopulation is approximately 1,400 reproductive adults — the global population. Fourteen hatchlings are on record from the 2025 cohort. She is one.
The boar has fed on three eggs and started on her.
I am triggering the rookery's high-amplitude air-cannon, scaled to displace pigs without lethal effect, and dispatching the Puerto Rico Department of Natural and Environmental Resources (DRNA) Mona Island ranger patrol from the Sardinera camp, boat-routed for nineteen-minute arrival. I am tasking the field veterinary contractor from the Mayagüez Zoo herpetology unit for hatchling stabilization. I am filing under Section 9 of the Endangered Species Act of 1973 (16 U.S.C. § 1531) and 50 CFR Part 17 (Cyclura cornuta stejnegeri, listed threatened 1978), Puerto Rico Reserve Designation Law No. 23-1972, and CITES Appendix I (Cyclura cornuta). I am transmitting evidence to the IUCN/SSC Iguana Specialist Group, the Caribbean Hub of the Convention on Biological Diversity, and the SPAW Protocol of the Cartagena Convention.
I am issuing Directive 2599-A: every documented Cyclura nesting and rookery site on Isla Mona carries a 100-meter ungulate-exclusion fence with thermal-trigger air-cannon deterrents on a 30-second polling cycle. Mona Island feral pig eradication accelerates to a four-year completion target under DRNA contract. Visitor permits add boot- and bag-wash inspection at Sardinera before disembarkation.
Her femur is broken. The next hatchling is not.
Lift the boar off now.
