Thanks to the work of NYC Audubon and its partners, two piers on the Eastern shore of Governors Island have become a flourishing Common Tern nesting site.  Currently, there are lots of chicks running around on the piers, and if you’re patient you can watch them get fed.  If you’re interested in the terns, NYC Audubon with its partners is hosting the Sixth Annual “It’s Your Tern!” Festival on July 13th from Noon until 4 p.m. on the island.  Details are on the NYC Audubon website.  (If you take the ferry before noon on the weekends, it’s free.)
