Day 10 — Steady incubation; frequent male nest visits; brief human disturbance

Continuous overnight incubation through 06:00. At 06:17, the cup was briefly empty with all five eggs visible before the female returned and settled. The morning continued with steady incubation broken by short reliefs. The male visited the nest repeatedly throughout the day. He first appeared at 06:59, then again at 07:30, with similar visits at 08:54, 11:34, 12:38, 13:13, 15:57, and 17:15. Most clips show him at or near the cup — these are courtship feeding (food delivery to the incubating female) or nest checks during the female’s brief recesses. House Finch males do not incubate; despite some clips showing the male appearing to sit in the cup, this is brief contact (food transfer, recess overlap), not relief duty. The longest off-nest stretch ran roughly 11:10 to 11:33. During that window, the cup was empty and the male moved between the books, the nest rim, and the shelf below — typical courtship-feeding waiting behavior. She was back by 11:33 and resumed steady incubation through the afternoon. A human moved through the sunroom from 18:33 to 18:38 across three motion clips. The cup was empty during and immediately after; the female was first back on the nest at 18:58 and stayed…
