Swallow-tailed Gulls: The swallow-tailed gulls (Creagrus furcatus) is one of the world's most beautiful gulls.
It is endemic to the Galapagos Islands and is also unusual in being one of the few species of gulls that feeds out to sea at night. |

this large gull gas red feet and crimson eye-ring to set off its beautifully textured black, grey and white plumage.
The swallow -tailed gull is colonial and is found on most small islands and on cliffs of larger islands. There do not seem to be as many in the western islands where the waters are cooler.
Brown Noddy: The brown noddy, (Anous stolidus), is a dark brown tern-like bird with pointed wings and along wedge-shaped tail. The whitish forehead and white eye-ring of the adult contrast sharply with the rest of the body. Brown noddies feed mainly on small fish and fry that are at the sea's surface. They can sometimes be seen in large flocks where schools of fish are being attacked from below by tuna or other game fish. The brown noddy is also often seen feeding together with pelicans and other seabirds.
When with a group of pelicans, these small dark birds flutter about frequently alighting on a pelican's head or back. From this vantage point, they wait for the bird to empty its pouch and then snatch up any scraps that drain out. This behaviour is a remarkable example of how one species can take advantage of another's actions without, seemingly, interfering. |
