Governors Island is now open after dark on Fridays and Saturdays, so I went in search of bats on Saturday.  I saw and recorded echolocations from two Eastern Red Bats at Nolan Park around 8:15-8:45 p.m. 

Earlier in the daylight, I enjoyed views of the Yellow Crowned Night Heron nest, Killdeer and Common Terns.  I was also able to see the three young Peregrine Falcons and their mother at 55 Water Street.

The Common Terns nest on two of the piers, Lima and Tango.   NYC Audubon is encouraging Common Terns to nest on the Lima Pier this year and has put up three decoys.  It took me awhile to realize there were decoys and I had to subtract three Terns from my eBirds checklist.

They piers are named after their shapes, L, T and Y, which in the NATO alphabet become, Lima, Tango and Yankee.  The Yankee pier, which now only is half a Y, is in active use by the Brooklyn bound ferry.

In addition to the birds on Memorial Day weekend, there was a military ship being guarded by the Coast Guard across Buttermilk Channel and a few military plane and helicopter flyovers.
