I went to see the three eyasses on the nest at Washington Square Park and got a surprise. Two adult hawks were in the park. One I hadn't seen before on the Education Building (rusted beam next to the hawk) and the Adult Female on One Fifth Avenue. They both flew around and the Adult female didn't seem happy with the intruder.
The three eyasses could start fledging later this week. The photographs always show two, but there was often one hiding in either corner of the nest.
