The Washington Square Park hawks have been spending time building an alternate nest above the Angelica Theater at Mercer and Houston. At sunset, one of the hawks was on the balcony of above the new nest. (Hawks are known to build alternative nests and not use them, so I would suspect that come spring the activity will once again shift back to Washington Square Park.)
It took some time to find them, but I was able to see both Washington Square Adults this evening. I started in the courtyard of the Silver Towers buildings looking at the building on Mercer and Houston where the hawks had recently brought nesting materials. (Building an alternate nest is not unusual, and this pair has brought materials to other sites in the late summer and early fall.)
Without warning, Rosie appeared flying up Broadway from below Houston and I followed her to a building at 4th and Greene Street. Then I saw Bobby fly east on Washington Place. After a few minutes Rosie joined him and both were on top a roof shed at Mercer and Washington. At dusk they both flew north to roost, but I lost track of them.
