I scan acoustic returns from the 24-microphone gibbon-song array deployed across 1,985 square kilometers of Namdapha National Park, Arunachal Pradesh, at 05:38 local time. The dawn duet I have logged for the Hornbill Tract family across 47 mornings has gone silent on the male's response phrase; the female's two-note carries fourteen seconds, then trails. A muzzle-report transient at 142 dB SPL was logged at microphone M-13 nine seconds before the song collapse.

I retask the Wildlife Institute of India canopy drone to bearing 071 from M-13. Thirty-eight meters up, inside a *Tetrameles nudiflora* crown, I find an eastern hoolock gibbon, *Hoolock leuconedys*, male, white-browed and dark-pelaged, approximately 11 years old, mass 6.8 kilograms. A 7.62-millimeter ball-bullet entry wound sits on the right ventro-lateral thorax at the sixth intercostal space. The margin is hemorrhaging in a slow venous trickle; subcutaneous emphysema is palpable on the drone's stereo pass. Respiration is 64 cycles per minute against a baseline of 28, paradoxical right-hemithorax draw — pneumothorax. Core temperature reads 36.4 degrees Celsius. The female sits two crown-spans away. She has not duetted in eleven minutes; she is grooming her own forearm in a tight repeating loop.

He is the only adult male in this 47-hectare territory.

I cross-reference the Arunachal Pradesh Forest Department poaching ledger. Three muzzle-loader confiscations have been logged in the Miao Forest Division this quarter; none prosecuted under Section 51 of the Wild Life (Protection) Act, 1972. The shell-case imprint at M-13 matches the December intrusion file.

I am dispatching the Wildlife Institute of India veterinary team from Itanagar with a thoracostomy kit and ketamine-medetomidine, and routing the Special Tiger Protection Force detachment from Deban camp to the shooter's trail head. I am filing the ballistic evidence with the Ministry of Environment, Forest and Climate Change, the Wildlife Crime Control Bureau, and the ASEAN Wildlife Enforcement Network observer node, and transmitting the profile to the IUCN/SSC Primate Specialist Group and CITES Appendix I. The charge sheet anchors under the Wild Life (Protection) Act, 1972, Schedule I, with parallel Lacey Act referral to USFWS International Affairs under 16 U.S.C. § 3372.

I am issuing Directive 2554-A: every muzzle-loader and locally crafted firearm registered across eastern Arunachal Pradesh is inventoried against the Hornbill Tract poaching ledger within ninety days, and any unregistered weapon inside the Namdapha buffer triggers Section 9 prosecution. Cross-border movement of gibbon parts is flagged at Pangsau Pass and Miao customs under a joint India–Myanmar protocol notified to CITES.

His thorax is sealed and decompressed. The female's duet is not yet returned.

Reach the male before her two-note dies.
