A visit today to Highbridge Park, found their nest to be active with two or three eyasses (baby hawks).  Both parents were both engaged in keeping the eyasses warm and feeding them.  This pair consistently has eyasses in mid-April, and they continue the tradition this year.

At the end of the video, note that the mother comes back with a wet set of chest feathers. (For those who might not believe this is Manhattan, in the video, you can see one of the Circle Line boats pass by!)
