Dunlin & Sanderlings near Blakemans - Duxbury Beach, MA - April 27, 2013
A large group (800+/-) of Dunlin with Sanderlings were working the edge of high tide on the oceanside opposite Blakeman's. They often arose to perform a few beautifully synchronized aerobatic maneuvers and resettled at the peak of the incoming waves. This photo and the previous one provide the feel of the moment.
