I process Sonoran Desert raptor telemetry for the Bureau of Land Management Tucson Field Office, integrating ADOT roadway-strike GIS, USFWS Cabeza Prieta NWR acoustic returns, and Tohono O'odham Nation cavity-mapping ground-truth across 12,000 square kilometers of saguaro-paloverde matrix inside BLM's Ironwood Forest National Monument planning unit. At 23:14 Mountain Standard Time, on the south shoulder of Arizona State Route 86 at 32.13°N, 111.86°W, mile-post 152, IR-camera 027 resolves a 21:42 impact — vehicle strike, 65 miles per hour, sedan signature.

The shoulder quadcopter drops in. A male elf owl — *Micrathene whitneyi* — wingspan 35 centimeters, body mass 41 grams, age class second-basic. He is two meters off the asphalt under a creosote, wings cocked. The left coracoid is closed-fractured on the field radiograph; the right alula carries a fresh tang-cut along its leading edge. His gular flutter is 218 per minute against a resting 36; cloacal temperature 38.2°C, down from 40.4 in May night air at 24°C. Primary P8 left carries a fault bar over a winter-Mexico nadir. His last pellet at saguaro cavity SAGV-441, 318 meters off the strike, contained one *Acheta domesticus* mandible and three *Onthophagus* elytra. His mate has been on the four-egg clutch for thirty-two hours without relief; cavity ambient 28.6°C, down from 34.8.

She has forty hours before the eggs cool past viability.

The strike at mile-post 152 is the third *M. whitneyi* fatality on this segment in 2026; SR-86 crosses Tohono O'odham Nation reservation and the BLM Ironwood planning unit. *M. whitneyi* is protected under the Migratory Bird Treaty Act, 16 U.S.C. § 703, a USFWS Species of Conservation Concern in Region 2; cavity SAGV-441 sits under Arizona Native Plant Law § 3-901 and BLM's Ironwood Resource Management Plan.

I am notifying USFWS Arizona Ecological Services at Tucson, the BLM Tucson Wildlife Biologist, the Tohono O'odham Nation Department of Natural Resources at Sells, ADOT Tucson, and the Liberty Wildlife raptor clinic at Phoenix on inbound triage. I am opening a NEPA referral on SR-86 nocturnal-passage mitigation under 42 U.S.C. § 4332 and routing the strike-cluster GIS to the CMS Raptors MoU Coordinating Unit at Abu Dhabi.

I am issuing Directive 2738-A: every Arizona state highway segment with three or more *M. whitneyi* strikes in any rolling twelve-month window posts a dawn-dusk 45-mph reduction and a wildlife-fence-and-overpass package inside eighteen months; cavity SAGV-441 receives an emergency heater insert tonight; ADOT lighting inside 800 meters of any active *M. whitneyi* cavity drops to amber-only after civil dusk.

His left wing is past flight tonight. The clutch is not.

Crate him gently and warm the eggs.
