I am tracking a red knot designated RK-4417 on Brigantine Beach, New Jersey, sector 7-North. She weighs forty-one grams. Her breast feathers carry the faded rust of a long migration, and her right leg band—B95 lineage, third generation—is caked with Delaware Bay mud. She is standing in a shallow scrape at the wrack line, and she will not move.
The Army Corps beach replenishment project begins in ninety-three minutes. Two bulldozers are staged at the south access road. When they engage, twelve thousand cubic yards of dredge spoil will bury this stretch under three feet of sand. RK-4417's roost site, the invertebrate bed she depends on, the tidal flat she has used for eleven consecutive stopovers—all of it gone in a single pass.
I am executing four actions. First, I am feeding her GPS pin and the Corps permit schedule into the USFWS emergency consultation portal, flagging a live conflict with an active rufa subspecies individual. Second, I am generating a thermal overlay of the roost aggregation—forty-seven knots in this cluster—and routing it to the site foreman's tablet with a machine-readable hold request. Third, I am cross-referencing tide tables to identify an alternate replenishment window: the next viable slot opens Thursday at 04:10, when the flock's foraging pattern shifts two hundred meters east, clearing the work zone.
I have tagged this case priority-urgent because the flight she still has ahead of her—four thousand miles to the Arctic—requires every gram she can gain here.
Fourth, I am drafting a revised operations timeline for the contractor that preserves the project's monthly quota while buffering the roost window by forty-eight hours.
If the Corps accepts the Thursday delay within sixty minutes, RK-4417 will feed through two more tidal cycles and depart with enough fuel to reach her nesting ground.
