Waved albatrosses are not the only bird you can watch along the southern coastline and patrolling the skies. In the foreground, you will see this is a favorite spot for Nazca bobbies and swallow-tailed gulls. Overhead is a squadron of blue-footed bobbies going out to sea to hunt as a flock. The white birds with the long tail streamers are red-billed tropicbirds. They are common along many tropical cliffs in the Pacific, Caribbean and Indian Oceans. Some ornithologists suggest those found at Plaza Sur, Genovesa, North Seymour and Española islands should qualify as a unique subspecies. Until a consensus is reached, they are classified as Phaethon aethereus.
