I visited the Washington Square Park nest in January and February, but my timing was bad each time and I only saw a few glimpses of the hawks.  I had much better luck today with the female on One Fifth Avenue, with a fly-by by the male who had a rat.  He shared it on the Student Center building and they both made a few visits to the nest.  Then they both went east and I lost track of them over the Law School.  Both they and the nest look great and I expect we'll see eggs in a few weeks.
