Today, I got to the 1115 Fifth Avenue nest a bit after noon to find the workman on a rig near the nest, but the brooding female calmly sitting on the nest. I had been concerned about how she would react to the rig being near the nest when I saw them move the supports closer to the nest on Wednesday.
Given that things seemed to be fine, and fog was making it hard to see the 1115 Fifth Avenue nest, I looked at other nests. The 350 Central Park West nest is empty, and I also checked on the St. John the Divine nest, which was also empty, although I did see a hawk on the Telephone Co. Building. I then made a trip down to Washington Square Park, and found the new female in the nest but not yet sitting on eggs. I will detail what I saw in a separate post.
I then returned to the 1115 Fifth Avenue nest in the late afternoon and a group of us came to understand that the 1115 Fifth Avenue pair was the 350 Central Park West pair. The female has the same deformed tail. But more interestingly, the male was perched on the building at the southwest corner of 96th and Central Park West, which has a perfect view of the new nest. At dusk, he flew over and gave the female a ten minute break. This explained why we had been seeing him so often near the old nest. It’s only three blocks away from the new nest, and they’re maintaining the territory. Riddle solved.
