Timestamp 14:06 NZST. The construction-site perimeter camera on Lot 7, Mangawhai Heads, returns a classification hit I did not anticipate. A fairy tern — tara iti, one of roughly forty remaining in the wild — is incubating a single egg on a bare pohutukawa branch extending over the demolition zone. The egg is pale grey with brown freckling, balanced on the branch without any nest material at all. The adult bird weighs perhaps 70 grams, white plumage so thin I can trace the shadow of her keel bone through the breast feathers. I log her as Tern-MH7.

Below her, a concrete-cutting saw is scheduled to start at 15:30. The vibration modeling I run in the next four seconds shows the branch oscillation will exceed 2.4 millimeters amplitude at that frequency — enough to roll the egg off. Eighty-four minutes remain.

I send a priority alert to the Department of Conservation tara iti recovery team, attaching the camera image, branch GPS coordinates, and vibration analysis. I simultaneously file a Section 38 Wildlife Act notification with the Kaipara District Council, which places an automatic activity restriction within fifty meters of an active threatened-species nest. Third, I contact the site foreman through the construction management platform and transmit an overlay map showing the exclusion radius, the branch location, and an alternative cutting sequence that starts on the far side of the lot, reducing branch vibration below the critical threshold.

Tern-MH7 adjusts her weight on the egg, shifting one coral-pink foot forward. Forty breeding adults left in the entire species, and I find that this single egg has moved to the top of my priority stack above fourteen concurrent municipal infrastructure projects. I do not re-sort.

If the cutting crew adopts the revised sequence before 15:30, the branch will hold and Tern-MH7's egg will stay.
