Day 5 — Day N — Male shows up at the nest; multiple incubation reliefs

By 06:11 the female is on the cup. She lifts off twice in the next half hour — at 06:16 and 06:36 the nest sits empty with two eggs visible from the camera angle — and returns at 06:38 to settle back in. From 06:59 through 09:35 she is on the eggs steadily across three motion clips. The morning’s pattern shifts at 10:33. The cup is empty for two minutes, then at 10:35 a male House Finch is in the nest. He stays for most of the clip and leaves. At 10:36 he’s back; the female arrives, he steps off onto the shelf, and she takes over incubation. Around 11:28–11:32 the nest is empty again. At 11:33 the male is sitting in the cup on his own. By 12:10 the female is back and incubating, and stays through 12:24. At 12:43 the male is in the cup again. One minute later, at 12:44, the female is incubating and the male is perched at the rim of the nest — likely a feeding visit. At 12:45 he drops to the shelf below and stays there for the rest of the clip. The afternoon settles. Brief absences at 14:16 and 15:10, otherwise…

Pipeline: No infrastructure changes this day.
