The Saint Helena shearwater (Ardenna pacificoides) is an extinct species of seabird in the petrel family. It is known only from subfossil remains found on the island of Saint Helena in the South Atlantic Ocean. It probably became extinct at the end of the last glacial period, or the early Holocene, as the climate became warmer. [2]
The specific name of the taxon comes from pacificus plus Greek oides (like or resembling), from its relationship to the living species Puffinus pacificus (now known as Ardenna pacifica ). [3] It was later recognized as a species of Ardenna since 2018. [4]
Puffins are any of three species of small alcids (auks) in the bird genus Fratercula. These are pelagic seabirds that feed primarily by diving in the water. They breed in large colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the tufted puffin and horned puffin, are found in the North Pacific Ocean, while the Atlantic puffin is found in the North Atlantic Ocean.
Shearwaters are medium-sized long-winged seabirds in the petrel family Procellariidae. They have a global marine distribution, but are most common in temperate and cold waters, and are pelagic outside the breeding season.
The family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prions, and the shearwaters. This family is part of the bird order Procellariiformes, which also includes the albatrosses and the storm petrels.
The great shearwater is a large shearwater in the seabird family Procellariidae. It breeds colonially on rocky islands in the south Atlantic. Outside the breeding season it ranges widely in the Atlantic.
The sooty shearwater, or tītī, or muttonbird, is a medium-large shearwater in the seabird family Procellariidae. In New Zealand, it is also known by its Māori name tītī, and as muttonbird, like its relatives the wedge-tailed shearwater and the Australian short-tailed shearwater.
Puffinus is a genus of seabirds in the order Procellariiformes that contains about 20 small to medium-sized shearwaters. Two other shearwater genera are named: Calonectris, which comprises three or four large shearwaters, and Ardenna with another seven species.
The flesh-footed shearwater is a medium-sized shearwater. Its plumage is black. It has pale pinkish feet, and a pale bill with a distinct black tip. Together with the equally light-billed pink-footed shearwater, it forms the Hemipuffinus group, a superspecies which may or may not have an Atlantic relative in the great shearwater. These large shearwaters are among those that have been separated into the genus Ardenna. Recent genetic analysis indicates evidence of strong divergence between Pacific colonies relative to those in South and Western Australia, thought to be explained by philopatry and differences in foraging strategies during the breeding season.
Buller's shearwater is a Pacific species of seabird in the family Procellariidae; it is also known as the grey-backed shearwater or New Zealand shearwater. A member of the black-billed wedge-tailed Thyellodroma group, among the larger shearwaters of the genus Ardenna, it forms a superspecies with the wedge-tailed shearwater.
The pink-footed shearwater is a species of seabird. The bird is 48 cm (19 in) in length, with a 109 cm (43 in) wingspan. It is polymorphic, having both darker- and lighter-phase populations. Together with the equally light-billed flesh-footed shearwater, it forms the Hemipuffinus group, a superspecies that may or may not have an Atlantic relative in the great shearwater. These are large shearwaters which are among those that could be separated in the genus Ardenna.
The Saint Helena hoopoe, also known as the Saint Helena giant hoopoe or giant hoopoe, is an extinct species of hoopoe known exclusively from an incomplete subfossil skeleton. Once endemic to the island of Saint Helena, it was last seen around 1550, likely driven to extinction by various aspects of human activity.
The Saint Helena crake is an extinct bird species from the island of Saint Helena in the South Atlantic Ocean, one of two flightless rails which survived there until the early 16th century.
The Saint Helena rail was a large flightless rail from Saint Helena. It became extinct in the early 16th century.
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 Saint Helena dove is an extinct species of flightless bird in the family Columbidae. It is monotypic within the genus Dysmoropelia. It was endemic to the island of Saint Helena in the South Atlantic Ocean. It is known from remains of Late Pleistocene age found at the Sugarloaf Hill locality, which consists of aeolian calcareous sands. The holotype consists of a right coracoid, with paratypes consisting of "distal end of right tarsometatarsus, (S/1963.25.29) distal half of right humerus, (S/1963.25.26) worn left tibiotarsus lacking distal end, distal portion of shaft of left tarsometatarsus, (S/1963.25.30) worn proximal end of right humerus. left ulna, proximal fragments of left ulnae, (175959) proximal end of right femur, (175962) distal end of right humerus"
Storrs Lovejoy Olson was an American biologist and ornithologist who spent his career at the Smithsonian Institution, retiring in 2008. One of the world's foremost avian paleontologists, he was best known for his studies of fossil and subfossil birds on islands such as Ascension, St. Helena and Hawaii. His early higher education took place at Florida State University in 1966, where he obtained a B.A. in biology, and the University of Florida, where he received an M.S. in biology. Olson's doctoral studies took place at Johns Hopkins University, in what was then the School of Hygiene and Public Health. He was married to fellow paleornithologist Helen F. James.
Nelson Philip Ashmole, commonly known as Philip Ashmole, is an English zoologist and conservationist. His main research field focused on the avifauna of islands, including Saint Helena, Ascension Island, Tenerife, the Azores, and Kiritimati. Other interests include insects and spiders, of which Ashmole discovered and described some new taxa.
