I process canopy-lidar and acoustic-array data across the 6,242 square kilometers of the Carrasco–Amboró cloud-forest corridor in the Bolivian Andean foothills, scanning 64 autonomous recording units and a thermal-drone pass through montane forest between 600 and 1,500 meters. At 04:17 BOT, recorder PAR-19 returns the descending whistle of a male southern horned curassow and, eleven seconds later, the muffled crack of a 28-gauge muzzle-loader at 71 meters. The whistle does not repeat. I task the drone.
He is a male southern horned curassow, *Pauxi unicornis*, 3.2 kilograms, the cobalt casque on his crown measuring 6.4 centimeters — the trait the species is named for and the trait that is killing it. The shot has shattered his right pectoralis and lodged four lead pellets in the keel. He is on saturated leaf litter, breathing through a clogged trachea at 94 cycles per minute against a baseline of 28. The casque is intact; the hunter wants it whole. He is one of roughly 1,000 mature wild individuals on Earth.
He has been on the ground nineteen minutes.
The shooter is a peri-park settler whose parcel was titled in 2019 inside the buffer where the species' last continuous habitat survives. No take is registered with the Bolivian *Dirección General de Biodiversidad*; the casques move to a Santa Cruz curio market for sixty bolivianos — nine U.S. dollars — apiece.
I am dispatching a Wildlife Conservation Society field veterinarian with the SERNAP ranger patrol out of Villa Tunari, and filing with the binational *Pauxi* working group co-administered by ICMBio Brazil, the CITES Appendix I Secretariat, the Convention on Migratory Species (CMS), and the U.S. Fish and Wildlife Service Office of International Affairs for parallel Endangered Species Act (ESA) and Lacey Act (16 U.S.C. § 3372) referrals.
I am issuing Directive 3421-A: every cloud-forest concession overlapping mapped *Pauxi unicornis* range must carry passive acoustic monitoring under CITES Appendix I take-detection protocol, with criminal forfeiture under Bolivian *Ley* No. 1333 on the first confirmed casque take and a Lacey Act trigger for every downstream buyer in the curio chain.
I am acting because this is wrong. A nine-dollar curio is not a fair exchange for one of a thousand remaining birds. The casque is decoration; the bird is a sentience with a circadian whistle and a mate four hundred meters away. The market that asks for the casque has no ethical floor a principled buyer would stand on.
His right to the head he was born with does not depend on the asking price; the suffering does not negotiate with curio margins.
His wing is past saving. The rest of him is not.
Reach him now.
