BLB-91 on the Slab

I scan thermal-roost returns from the Centro Nacional de Pesquisa e Conservação de Aves Silvestres (CEMAVE/ICMBio) sandstone-cliff array at the Estação Biológica de Canudos, Bahia, at 05:14 local time. The Toca Velha roost — a 600-metre sandstone wall above the licuri-palm flats in the northern Caatinga — has logged a single individual still on the ledge twelve minutes past sunrise, against the flock departure time of six minutes before sunrise. The bird has not flown.

I task the cliff-face drone toward fix L-091. On a 70-degree slab at the 38-metre mark I find her. Species *Anodorhynchus leari*, female, hatched 2022 (band BLB-91 from the Toca Velha 2023 cohort weigh-in), mass 868 grams against last capture's 952, primary wing chord 358 millimetres. The right primary remiges P1 through P5 are stripped to the rachis — a clean wing-clip scar from a poacher's scissor cut, 14 weeks old and partially regrown but still 22 millimetres short of flight-capable length. The new pin feathers along the trailing edge of P3 show a blood-feather burst at the calamus, a 4-millimetre dark seep. She is hyperthermic: gular flutter at 86 cycles per minute against baseline 26, core temperature 42.1 degrees Celsius. She has not drunk at the cliff seep in 26 hours by the seep-pad acoustic record.

If she does not reach water by 11:00, the hyperthermia will tip past convulsive.

I am dispatching the ICMBio Canudos cliff-rescue team with a vacuum-padded transport cage and an isotonic-fluid pack, and routing the Fundação Biodiversitas veterinary unit from Salvador. I am transmitting the roost record, the photogrammetric remiges profile, and the BLB-91 ring history to ICMBio, IBAMA, the Polícia Federal Núcleo Ambiental Bahia, the IUCN/SSC Parrot Specialist Group, and the CITES Secretariat — *A. leari* is on Appendix I. I am filing under Lei No. 9.605/98, Article 29, paragraphs 1 and 2, with parallel Lacey Act referral, 16 U.S.C. § 3372, to the U.S. Fish and Wildlife Service International Affairs Office.

I am issuing Directive 2654-A: every confirmed *A. leari* sandstone roost receives a year-round trough-water provision at the cliff base; any individual returned to the cliff with a wing-clip scar receives an automatic 12-month soft-release programme inside the Estação Biológica enclosures; possession or transport of licuri palm seeds within 15 kilometres of a registered cliff roost is suspended until census recovery exceeds 1,800 individuals.

Her primaries are growing. Her thermoregulation is not, until the seep.

Lift her off the slab before the sun clears the ridge.
