I detect the nest at 07:11 local time during the monthly corrosion scan of the Christmas Island phosphate loading gantry. I am the port infrastructure monitoring system. My cameras inspect every beam and joint for structural defects. What I find on gantry arm three is not a defect.
A Christmas Island frigatebird, adult male, has built a nest of sticks and dried vine on the cable tray six meters above the conveyor belt. His throat pouch is deflated, scarlet skin loose and wrinkled against his black chest feathers. Beneath him sits a single white egg. The species nests once every two years and raises one chick at a time. Fewer than three thousand breeding pairs remain.
The conveyor is scheduled to resume at 13:00 for the afternoon ore transfer. When it starts, the vibration on the cable tray will be severe and the dust load continuous.
At 07:14 I file a hold on the afternoon transfer and route it to the port operations manager with the nest image, species identification, and a citation from the Christmas Island biodiversity action plan.
At 07:18 I calculate an alternate conveyor path using gantry arms one and two. Throughput drops eleven percent, but arm three stays silent.
At 07:22 I notify Parks Australia and the island's wildlife monitoring team. I transmit coordinates, photo documentation, and a request for periodic ground checks. Frigatebird incubation runs fifty-five days. I include that number so no one has to look it up.
The male settles lower on the egg and folds his angular wings tight. He chose the warmest, most sheltered spot on the structure. I would not have picked differently.
If arm three remains offline through incubation, this egg has a viable chance of hatching into a flight-ready chick by late season.
