This Warbler was at the edge of the beach on Bulls Island, nicely camouflaged by his surroundings when he stayed in the undergrowth.
With a steady wind coming in from the Atlantic Ocean he limited his time on higher perches.
North America has more than 50 Warbler species, many that are quite distinct and easy to ID. This one seems to fit a few options to me, perhaps a Palm Warbler.
Bulls Island, Cape Romain National Wildlife Refuge, Awendaw, SC.
