Day 4 — Frequent short reliefs; camera work mid-afternoon clears the nest

The female is on the eggs at 06:00 and 06:03, gone by 06:39. The cup sits empty through the early morning until 08:23, when she arrives, settles briefly, and departs.

The morning runs as a series of short on-and-off shifts: back at 09:41, off by 09:47, on again at 10:32, off at 11:31, returning at 11:32, off until 12:44 when she returns to incubate. A male appears on the bookshelf near the nest at 10:33.

Afternoon brings more empty intervals. At 13:58 the cup is empty; a male visits the bookshelf at 14:00 and again at 14:01.

At 15:24, a person is at the camera, working on it. Human presence runs through 15:29 — several clips show him handling the device with the cup empty and eggs visible. The camera is repointed during this; from 15:30 to about 16:23, the field of view is mostly outside the window or otherwise unusable. The close camera resumes useful framing around 16:46, nest empty.

The cup stays empty through 17:30, 18:20, 18:25, 18:27, 18:28, 18:31, and 18:32 — eggs alone in every clip. The female is back on the nest by 19:25 (sunroom snapshot) and incubating again at 20:01 (sunroom motion). The old bookshelf cam captures its last usable frames at 20:27.

All five eggs remain visible across the day. The midafternoon human disturbance and the roughly 4.5-hour absence that followed are the day’s main anomalies.

Pipeline: No infrastructure changes this day.
