These guys are called black skimmers. We saw them on the beach in the Keys. They fly in groups, land in groups, and all seem to face the same direction while on the sand. They look like the are wearing little tuxes with a splash of color on their beaks and legs. Their eyes are set in the black area on their heads and are hard to see there. We had such fun watching them and hubby kept chasing the group from one place on the beach to another to get a shot of them. He made me laugh even more than they did.
