A little night music, flyover fanfare

This evening ,the New York Philharmonic held their annual parks concert in Prospect. During Antonín Dvořák Cello Concerto,2nd movement, i caught sight of 5 BLACK SKIMMERS flying over , heading towards Bartel Pritchard Square. Also a RED TAILED HAWK seen flying unto a perch; some Brown Bats later in the darkness ( I covered my neck)
