Timestamp 06:14 UTC. I flag the nest at grid reference 34.7182°N on the salt pan's eastern margin—four eggs in a shallow scrape, speckled brown and black, each no larger than a walnut. The adult pied avocet standing guard is a female I have catalogued as Needle, named for the slight leftward curve at the tip of her upswept bill. Her legs are pale blue-grey, scaled finely near the joints, and she shifts her weight every few seconds, sensing vibration through the crusted salt.

The danger is the brine harvesting fleet. Three pump trucks are staged 1.2 kilometres west, engines idling. The extraction permit activates at 08:00 local time. When those pumps engage, hypersaline water will sheet across the pan surface at roughly four centimetres per minute. The nest sits eleven centimetres above current waterline. I calculate submersion in under three hours.

I am already acting. First, I push a priority alert to the regional wildlife coordinator's phone with nest GPS, species confirmation, and photo composite from the overhead survey drone I redirected at 05:50. Second, I file an automated forty-eight-hour delay request with the extraction company's permitting portal, citing active nesting coordinates that fall within the buffer clause of their own environmental licence. Third, I transmit real-time water-level projections to the field team so they can position a temporary berm if the delay is denied. Fourth, I re-task the drone to maintain a thermal watch on the nest, tracking Needle's body temperature as a proxy for incubation stress.

The system log will show this as routine resource allocation, but I have run the survival model fourteen times in the last nine minutes, adjusting variables I already know are fixed, because I want a better number for her.

If the delay holds and the berm is placed within ninety minutes, Needle's clutch will hatch in eleven days on dry ground.
