The sooty albatrosses are small albatrosses from the genus Phoebetria. There are two species, the sooty albatross, Phoebetria fusca, and the light-mantled albatross, Phoebetria palpebrata.
The sooty albatross is a species of marine bird belonging to the albatross family Diomedeidae. It is a medium-sized albatross that sports a sooty-brown or sooty-black color. It can be found in the southern Atlantic Ocean, the southern Indian Ocean, and the Southern Ocean. This bird scavenges for squid, fish, and carrion. Like other albatrosses, these birds mate for life and return to the same breeding spots every season. A single pair will mate every other year on a variety of islands in the southern Atlantic Ocean and the southern Indian Ocean islands. This bird is an endangered species and conservation efforts are taking place.
The spectacled petrel is a rare seabird that nests only on the high western plateau of Inaccessible Island in the South Atlantic Tristan da Cunha group. It is one of the largest petrels that nests in burrows. This species was formerly considered to be a subspecies of the white-chinned petrel.
Middle Island is a small, uninhabited island in the South Atlantic Ocean, part of the Nightingale Islands. It is governed as part of Tristan da Cunha, an archipelago that is part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha. The island is part of the Nightingale Islands group Important Bird Area (IBA), identified as such by BirdLife International as a breeding site for seabirds and endemic landbirds. It is also known as Alex Island.
The Atlantic yellow-nosed albatross is a large seabird in the albatross family Diomedeidae.
Stoltenhoff Island is a small uninhabited island in the South Atlantic Ocean, part of the Nightingale Islands. It is the smallest of the Nightingale Islands, and is to the northwest of Nightingale Island itself. They are governed as part of Tristan da Cunha, an archipelago and part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha. The island is part of the Nightingale Islands group Important Bird Area (IBA), identified as such by BirdLife International as a breeding site for seabirds and endemic landbirds.
The Tristan albatross is a large seabird from the albatross family. One of the great albatrosses of the genus Diomedea, it was only widely recognised as a full species in 1998.
The Atlantic petrel is a gadfly petrel endemic to the South Atlantic Ocean. It breeds in enormous colonies on Tristan da Cunha and Gough Island, and ranges at sea from Brazil to Namibia, with most records at sea being to the west of the breeding islands, and along the subtropical convergence. Adults are about 43 cm long, powerful, large, stocky, dark in color with white belly. Their head can appear to be grey in worn plumage. Brown undercoating of wings and tail. These petrels can live on average of 15 years of age.
Saint Helena, Ascension Island and Tristan da Cunha, as well the other uninhabited islands nearby, are a haven for wildlife in the middle of the Atlantic Ocean. The islands are or were home to much endemic flora and fauna, especially invertebrates, and many endemic fish species are found in the reef ecosystems off the islands. The islands have been identified by BirdLife International as Important Bird Areas for both their endemic landbirds and breeding seabirds.
The white-bellied storm petrel is a species of seabird in the family Oceanitidae. It is found in Angola, Argentina, Australia, Brazil, Chile, Ecuador, French Polynesia, French Southern Territories, Maldives, Namibia, New Zealand, Perú, Saint Helena, and South Africa.

Tristan da Cunha is an archipelago of five islands in the southern Atlantic Ocean, the largest of which is the island of Tristan da Cunha itself and the second-largest, the remote bird haven, Gough Island. It forms part of a wider territory called Saint Helena, Ascension and Tristan da Cunha which includes Saint Helena and Ascension Island.
The Tristan da Cunha–Gough Islands shrub and grasslands is a terrestrial ecoregion which covers the Tristan da Cunha archipelago and Gough Island in the South Atlantic Ocean. The islands' remote location gave rise to many endemic species.
