Although I expected first hatch at the hawk nest at the Cathedral of St. John the Divine, it's looking like the schedule is something completely different. The female continues to spend substantive time away from the nest without the male tending it while she's away.
Sunday just before 6:00 I found both of the hawks on Norman's chimney at St. Luke's hospital. As events would demonstrate, Norman was eating dinner while Madeleine perched alongside.
Norman finished up about 15 minutes later and hopped across the chimney.
And a couple minutes later there was a quick mating.
Norman stayed for another fifteen minutes and then took off about 6:30. Madeleine stayed put, just watching the evening sky.
She was still there as 7:00 approached and I had to leave for Sunday dinner.
It's enough to make one wonder if the female spending time outside of the nest but within a short flight means there was a hatch a week or two ago, and she feels the baby(s) are big enough they don't need her to warm them. Or alternatively there's been an early nest failure.
