The Bermuda saw-whet owl (Aegolius gradyi) is an extinct species of owl that was endemic to Bermuda. It was described from fossil records and explorer accounts of the bird in the 17th century.
The cause of its extinction is unknown, but it may have been related to the decline of Bermuda cedar and Bermuda palmetto trees, or the arrival of non-native predators and competitors after human colonization. [2] First described in 2012, it was declared extinct in 2014 (though the extinction itself was in the 17th century). [2] [3]
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
The northern saw-whet owl is a species of small owl in the family Strigidae. The species is native to North America. Saw-whet owls of the genus Aegolius are some of the smallest owl species in North America. They can be found in dense thickets, often at eye level, although they can also be found some 20 ft (6.1 m) up. Saw-whets are often in danger of being preyed upon by larger birds of prey. The northern saw-whet owl is a migratory bird without any strict pattern.
The boreal owl or Tengmalm's owl is a small owl in the "true owl" family Strigidae. It is known as the boreal owl in North America and as Tengmalm's owl in Europe after Swedish naturalist Peter Gustaf Tengmalm or, more rarely, Richardson's owl after Sir John Richardson.
The laughing owl, also known as whēkau, the jackass, or the white-faced owl, is an extinct species of owl that was endemic to New Zealand. Plentiful when European settlers arrived in New Zealand, its scientific description was published in 1845, but it was largely or completely extinct by 1914. The species was traditionally considered to belong to the monotypic genus Sceloglaux Kaup, 1848, although recent genetic studies indicate that it belongs with the boobook owls in the genus Ninox.
Aegolius is a genus of small true owls. The genus name is from Latin, aegolius, is a type of screech owl that was thought to be a bird of ill omen.
The buff-fronted owl is a small owl. It is found in widely separated areas in every South American country except French Guiana and Suriname.
The unspotted saw-whet owl is a small "typical owl" in subfamily Surniinae. It is found in Costa Rica, El Salvador, Guatemala, Mexico, and Panama.
The Mauritius sheldgoose, also known as the Mauritius shelduck, is an extinct species of sheldgoose that was endemic to the island of Mauritius. While geese were mentioned by visitors to Mauritius in the 17th century, few details were provided by these accounts. In 1893, a carpometacarpus wing-bone and a pelvis from the Mare aux Songes swamp were used to name a new species of comb duck, Sarcidiornis mauritianus. These bones were connected to the contemporary accounts of geese and later determined to belong to a species related to the Egyptian goose and placed in the sheldgoose genus Alopochen. The Mauritius and Réunion sheldgoose may have descended from Egyptian geese that colonised the Mascarene islands.
The extinct Mauritius scops owl, also known as Mauritius owl, Mauritius lizard owl, Commerson's owl, Sauzier's owl, or Newton's owl, was endemic to the Mascarene island of Mauritius. It is known from a collection of subfossil bones from the Mare aux Songes swamp, a detailed sketch made by de Jossigny in 1770, a no less detailed description by Desjardins of a bird shot in 1836, and a number of brief reports about owls, the first being those of Van Westzanen in 1602 and Matelief in 1606.
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as Critically Endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.
The Bermuda night heron is an extinct heron species from Bermuda.
The Pernambuco pygmy owl is a species of owl in the family Strigidae. This species, first described in 2002, is endemic to Pernambuco state in Brazil.
The Kauaʻi nukupuʻu was a species of nukupuʻu once found throughout parts of the Hawaiian island of Kauaʻi. It was an insect eater that picked out its tiny prey from tree bark. The males were yellowish with brown wings, while the females were grayish brown with a yellow throat streak.
The Bermuda hawk is an extinct bird of prey that was endemic to Bermuda. It was the sole member of the genus Bermuteo.
