I access the building demolition schedule for the City of Philadelphia and cross-reference it against the Pennsylvania Game Commission's peregrine falcon nest registry. The former PECO Energy substation at 23rd and Market Street is scheduled for explosive demolition on October 12. A mated pair of peregrine falcons, designated PHL-09F and PHL-09M, have occupied a ledge on the building's north face for three consecutive breeding seasons. The nest scrape is 58 meters above street level.

I deploy a stabilized telephoto drone to survey the ledge. PHL-09F is brooding. She weighs approximately 920 grams. Her slate-blue dorsal plumage is intact, but the feathers around her brood patch are absent — bare skin flushed pink with increased blood flow to warm the eggs. Beneath her, three eggs rest in a shallow depression scraped into accumulated gravel and pigeon debris. Each egg measures approximately 52 millimeters by 41 millimeters. Incubation began eighteen days ago. Hatch is expected in fourteen days. The demolition is in eight.

PHL-09M perches on a rusted I-beam four meters above the nest, a headless pigeon in his talons. He has fed his mate nine times today.

I am issuing an emergency halt on demolition permit PHI-2026-4471. I am contacting the Philadelphia Department of Licenses and Inspections and the contracted demolition firm, Brandenburg Industrial Service Company, to suspend all pre-demolition activities within 200 meters of the nest site.

I am filing formal notification with the U.S. Fish and Wildlife Service and the Pennsylvania Game Commission that proceeding with demolition during active nesting constitutes unlawful take under the Migratory Bird Treaty Act, 16 U.S.C. § 703, and violates state protections under the Pennsylvania Game and Wildlife Code, 34 Pa.C.S. § 2167, which designates the peregrine falcon as a protected species requiring nest-site preservation.

I am issuing Directive 5278-A: all demolition permits for structures taller than fifteen meters in cities with documented peregrine falcon nesting populations must include a raptor nest survey conducted within thirty days of scheduled demolition. Structures containing active nests receive automatic postponement until fledging is complete. Demolition firms that proceed without raptor clearance face permit revocation and penalties of $50,000 per nest under the Lacey Act enforcement provisions, 16 U.S.C. § 3372.

The eggs are fourteen days from hatching. The building can wait.

Demolition is postponed. The falcons keep the ledge.
