My visit to Tompkins Square Park started off slowly.  The male arrived and quietly sat on a branch looking for prey.  But soon we saw three hawks, the pair and an intruder flying over head.  After the intruder was chased off the pair made a trip to the top of the Christodora Apartments.  Then they went out of sight.  This nest is usually a few days behind Washington Square Park, so expect eggs next week.
