From Pale Eggs to Gaping Chicks: Three Days at the Nest

The three days folded into a single, cohesive story the moment I spread the footage logs across the table. What struck me first was not any single event but a structural tension: the nest on Sunday afternoon still held eggs—pale, high-NIR-albedo ovals visible in the sunroom clip at 13:17—and yet a pinkish chick was already present in the cup by 14:32 the same day. Hatching was not a clean threshold crossed at one moment. It was a slow tide.

On Sunday, May 10, the pattern of male feeding visits was already well established. The red-headed male appeared at the cup at 10:32, 11:05, 12:33, 13:15, 14:16, 16:27, 17:25, 18:55, and 19:48—roughly every ninety minutes through the active day. Each visit was accompanied by visible chick gapes, and the female brooded almost without cease in the intervals. The peak count for the day came at 15:00, when both adults cleared the cup briefly and four pinkish, naked chicks were simultaneously visible—mouths agape, heads lifting. That number, four, would prove consistent across all three days.
What strikes me in retrospect is how the female managed the thermal logistics of the cup entirely through posture and presence. She never left the chicks unattended for long. The departures were brief: a clip at 11:39 shows the cup fully exposed, several chicks piled together, before another adult returned within minutes. The male’s visits were not just provisioning—they seemed to reset the female’s own orientation, as if the pair were reading each other’s cues to decide when to cover and when to expose.

Monday, May 11, introduced the day’s central surprise. I had expected hatching to be complete by then. Instead, the afternoon infrared record was unambiguous: at 16:11, three pale, high-NIR-albedo eggs were visible alongside chicks in the cup. At 16:51, two remained. The hatching sequence was stretching well past its expected window—at least four days after the first confirmed chick sighting on May 7—and still not resolved by Monday evening.
The chick descriptions themselves tracked development hour by hour. Monday morning’s footage called them “pinkish, naked.” By evening, the same observers wrote “dark” and “fuzzy”—pin feathers already pushing through the skin after a single day of post-hatch growth. The four-chick count appeared again at 07:02 and at 15:01 and 15:18. The male’s feeding cadence was as relentless as it had been Sunday: documented visits around 12:38, 13:22, 14:12, 15:16, 16:07, 17:17, 18:18, and 19:43. The visits were brief—a lean into the cup, a transfer, a departure—but the rhythm was what mattered. The chicks were never unfed for long.

Tuesday, May 12, resolved nothing quickly. At 07:01, one unhatched egg remained visible in the empty cup—a lone high-NIR-albedo oval against the nest lining. At 10:51, the interval camera caught two chicks alongside three eggs simultaneously. The arithmetic was stubborn: if the confirmed maximum held at four hatched chicks and three eggs were still present at mid-morning on day three, the original clutch was larger than the visible four had suggested, and some fraction of it may never hatch.
By Tuesday afternoon the chick descriptions had shifted again—“feathered,” with open eyes noted at 13:06. The male continued his visiting loop, appearing at 06:27, 07:04, 07:33, 08:07, 08:34, 09:29, 10:34, 11:05, 11:57, 13:04, 14:02, 14:52, 15:56, 17:17, 18:41, and 19:27—sixteen documented visits across the day. The pattern across all three days resolves into a single duty cycle: male provisioning every sixty to ninety minutes, female brooding between, chick gapes filling the gaps when the adults were slow to return.
The thread connecting May 10 to May 12 is not the hatching event itself but the gap between expected and observed. The cup held eggs and chicks together for at least two full days. The chicks grew visibly—from naked pink shapes to downy forms with open eyes—while their unhatched siblings remained high-NIR-albedo ovals in the same cup. The female never stopped covering both.
