No, I do not know what kind they are. I am not farmiliar with them myself, it was the first weekend I actually saw them up close. They were mean!! LOL I know they were just protecting their nest and we were trying to get out of the swamp area to the bay to go fishing. They sure guarded the opening to the bay LOL. They sure are beautiful though. There are geese here too, but none were in the water when we went out.
