Day 3 — Frequent short reliefs; male visits the nest area at 10:17

Pre-dawn coverage starts with the female on the nest at 06:16 and 06:23, shifting briefly to expose the eggs. She’s off by 06:28, and the empty cup with all five eggs is visible across both cameras.

The female returns at 11:13:59, perching on the rim, and is settled in by 11:54. After a midday break around…
