This Wed. I went out to Duxbury Beach, drove down near Saquish, and caught these shots.  Needless to say, the Peregrine was really exciting.  I believe the small plover is a Piping Plover, but I am waiting to hear back from Mass Audubon in Marshfield for s definite id.

The others are Ruddy Turnstones, Black Bellied Plover, Least Tern, and Semipalmated Plover.
