At Swan Cay (Isla de los Pajaros)I really don't think that you're supposed to go on the island. There were way too many birds nesting and we did seem to be disturbing them. This one was visible from the boat and my "guide" insisted that I should get closer. It didn't flush, but I still really felt like I was harassing it. The birds were flying all around the island and looked much more majestic in flight with their long tail feathers trailing behind.
