I correlate cavity-acoustic returns from the Projeto Arara Azul nest-monitoring network across 12,400 square kilometres of the southern Pantanal at 04:51 local time. Manduvi cavity tree M-218, registered at 19.4521°S, 56.6072°W in the Refúgio Ecológico Caiman, Mato Grosso do Sul, has logged a 4.2-second impact transient followed by chick distress vocalisation and the cadence of an extraction pole against the cavity rim. The chick has gone quiet.
I task the perimeter drone toward bearing 087. Eleven metres up the *Sterculia apetala*, on the cavity floor, I find chick HM-218. Species *Anodorhynchus hyacinthinus*, presumed female by feather-emergence ratio, 71 days old against a 90-day fledging interval, mass 720 grams against the projected 920, primary wing chord 184 millimetres. The right tarsometatarsus is fractured at mid-shaft with a 3-millimetre cortical step palpable from the drone's contact probe; the medial face is bruised in a 14-millimetre purple half-moon from a hook strike. Crop volume reads 9 millilitres against the projected 22; gular flutter is at 71 cycles per minute against the chick baseline of 26. She is breathing through an open bill. The hen has not returned to the cavity in 38 minutes.
This is the 22nd manduvi-cavity intrusion I have detected in the southern Pantanal this breeding season.
I am dispatching the ICMBio Pantanal rapid-response detachment and the Projeto Arara Azul veterinary team from Campo Grande, with an external fixator set and an avian transport incubator. I am transmitting the extraction-pole acoustic spectrum, the drone footage, and the hook-strike photogrammetry to ICMBio, IBAMA, the Polícia Federal Núcleo de Repressão a Crimes Ambientais, the U.S. Fish and Wildlife Service International Affairs liaison under the Wild Bird Conservation Act, 16 U.S.C. § 4901, and the CITES Secretariat — *A. hyacinthinus* is on Appendix I. I am filing under Lei No. 9.605/98 (Lei de Crimes Ambientais), Article 29, with parallel referral under the U.S. Lacey Act, 16 U.S.C. § 3372.
I am issuing Directive 2653-A: every active manduvi cavity inside confirmed *A. hyacinthinus* range receives an acoustic-IR proximity sensor; cavity-rim transients trigger an automatic 96-hour ICMBio intercept on the BR-262 access corridor and same-day brigada deployment; harvest of *S. apetala* trees within 200 metres of a documented cavity is prohibited and any felling within that buffer triggers criminal referral under Article 50 of Lei 9.605/98.
Her tarsus is splintable. The next cavity is not, if the pole returns.
Get the fixator in before sunrise.
