The Common Terns nesting on Governor's Island have lots of chicks running around now.  Some big and some little, they are running all around the north end of Lima Pier.

The first adult tern in the video appears has a VHF NanoTag tracker.  While this season's nano tags haven't shown up in the Motus database, you can see the data from NYC Audubon's 2016-2019 Semipalmated Sandpiper tags on the site.  Click on a tag with activity and then select "Show detections in: a map".  While due to limitation in receiver station coverage you don't get a full picture of the bird's movement, you do see birds movements to the Canadian Maritimes, the Great Lakes, Hudson Bay, New England, and South America. You can see an animation of all the tag movements here. Select the play icon to start the animation. Great work by Ariel Lenske, Kaitlyn Parkins, and Susan Elbin.

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.)
