Day 15 — Regular male feeding visits; 4 chicks confirmed; apparent unhatched egg

Female on nest continuously through the overnight period. First departure of the day at 05:58 briefly reveals 2 chicks in the cup; she is back within a minute. A second short absence around 06:16–06:19: the 06:18 departure clip logs 5 pale oval shapes as eggs, which is difficult to reconcile with the chicks confirmed 20 minutes earlier — most likely explanation is that unhatched eggs and already-hatched chicks are both present in the cup simultaneously. Cameras shift from IR to color around sunrise; the 06:25 clip is the first color footage, showing 3 chicks alongside an adult. The male makes at least 15 feeding visits between 06:27 and 19:51, with intervals varying from roughly 40 to 90 minutes. Several visits have both adults present at the nest simultaneously. Chick gaping is recorded in clips throughout the day. The highest confirmed chick count in a single clip is 4, from the sunroom camera at 10:21:44 during a male feeding visit. Between male visits the female broods with periodic short absences; empty-nest chick clips are scattered through the afternoon and evening, but gaps appear brief. She is settled back in the cup by 19:47; the record ends at 19:57 with the cup…
