The young hawk I had seen yesterday was in the same general area today. I first saw it around the playgrounds north of Tavern on the Green, and then on a C.P.W. building around 68th Street. Then it took off towards the Heckscher Ball Fields. When I caught up with the hawk, it had just finished up eating and was cleaning its beak.
Then I spotted Charlotte, the female hawk from Central Park South, on one of the Ball Fields. She took off towards the young hawk's tree with some prey.
The young hawk left, but ended up moving to a number of trees around the Ball Fields as Charlotte ate. I could not figure out all of the dynamics, but something was surely going on between the two of them.
