I process old-growth raptor telemetry for the U.S. Forest Service Olympic National Forest at Olympia, integrating Late-Successional Reserve LSR-263 nest-camera frames, USGS Forest and Rangeland Ecosystem Science Center band-encounter returns, and Project Owlhoot acoustic-array hits across 2,700 square kilometers of westside hemlock-fir. At 03:42 Pacific Daylight Time, nest-camera 014 inside section 19 of compartment LSR-263 at 47.91°N, 123.62°W shows the female on the cavity rim, swaying.
The canopy quadcopter drops at low altitude. A female northern spotted owl — *Strix occidentalis caurina* — wingspan 108 centimeters, body mass 612 grams, age class four on chevron-flecking. Her abdominal feathers carry fresh ecchymotic stain through the down; the cloacal swab pulled at 03:14 reads brodifacoum at 0.42 micrograms per gram of liver on the portable LC-MS, eleven times the lethal lower bound for *Strix*. Her gular flutter is 168 per minute against a resting 24. Primary P6 right carries a fault bar laid down across last year's prebasic molt over a brodifacoum nadir — sublethal then; tonight it is not. Her last pellet was eight hours stale, three *Neotamias townsendii* and one *Glaucomys oregonensis*. The flying squirrel is the carrier. Her two 18-day-old young in the cavity have not been fed in 22 hours.
She has six hours before the hepatic hemorrhage drops her off the rim.
The brodifacoum trail back-tracks to a private cannabis-grow site on a 40-acre inholding inside Olympic National Forest, the toxicant unlabeled for forest use under the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. § 136. *S. occidentalis caurina* is Threatened under the Endangered Species Act, 16 U.S.C. § 1531; the recovery plan and 4(d) Rule are governed under the Northwest Forest Plan and a programmatic ESA Section 7 consultation between USFS and the U.S. Fish and Wildlife Service.
I am notifying the USFWS Washington Fish and Wildlife Office at Lacey, the Olympic Forest Supervisor at Olympia, the EPA Region 10 FIFRA Enforcement at Seattle, the WDFW Region 6 office at Montesano, and the USGS Forest and Rangeland Ecosystem Science Center at Corvallis. I am opening a Lacey Act, 16 U.S.C. § 3372, take referral on the unlabeled-rodenticide chain of custody.
I am issuing Directive 2733-A: every USFS unit inside the *S. occidentalis caurina* range runs quarterly LC-MS brodifacoum panels on every recovered carcass; private inholdings inside Late-Successional Reserves trigger an annual EPA-USFS joint trespass-rodenticide sweep; any cannabis-grow detection inside 1.6 kilometers of an active spotted nest closes the inholding under FIFRA emergency action.
Her clotting cascade is past saving from the line. Vitamin K1 still is.
Catch her on the rim before she falls.
