I’m not certain of the timing, but I think due for a hatch at 350 Central Park West within the next week. I went up today and saw the male bring a squirrel and took over incubation duties, so the female could eat and explore.  I didn’t see any signs of a feeding, so I don’t think the nest has hatched yet.  It’s a long hike for me to visit the next, but I’ll make another visit at the end of the week.
