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 Carolina parakeet, or Carolina conure, is an extinct species of small green neotropical parrot with a bright yellow head, reddish orange face and pale beak that was native to the Eastern, Midwest and Plains states of the United States. It was the only indigenous parrot within its range, as well as one of only three parrot species native to the United States. It was called puzzi la née or pot pot chee by the Seminole and kelinky in Chickasaw. Though formerly prevalent within its range, the bird had become rare by the middle of the 19th century. The last confirmed sighting in the wild was of the ludovicianus subspecies in 1910. The last known specimen, a male named Incas, perished in captivity at the Cincinnati Zoo in 1918, and the species was declared extinct in 1939.
The true owls or typical owls are one of the two generally accepted families of owls, the other being the barn owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genera. The typical owls have a cosmopolitan distribution and are found on every continent except Antarctica.
Barn-owls are one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the Strigidae in structural details relating in particular to the sternum and feet.
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 Tengmalm's owl or Boreal 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.
In paleontology, a Lazarus taxon is a taxon that disappears for one or more periods from the fossil record, only to appear again later. Likewise in conservation biology and ecology, it can refer to species or populations that were thought to be extinct, and are rediscovered. The term Lazarus taxon was coined by Karl W. Flessa & David Jablonski in 1983 and was then expanded by Jablonski in 1986. Paul Wignall and Michael Benton defined Lazarus taxa as, "At times of biotic crisis many taxa go extinct, but others only temporarily disappeared from the fossil record, often for intervals measured in millions of years, before reappearing unchanged". Earlier work also supports the concept though without using the name Lazarus taxon, like work by Christopher R. C. Paul.
The laughing owl, also known as whēkau 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 SceloglauxKaup, 1848, although recent genetic studies indicate that it belongs with the boobook owls in the genus Ninox.
The Bermuda petrel is a gadfly petrel. Commonly known in Bermuda as the cahow, a name derived from its eerie cries, this nocturnal ground-nesting seabird is the national bird of Bermuda and can be found pictured on Bermudian currency. It is the second rarest seabird on the planet and a symbol of hope for nature conservation. They are known for their medium-sized body and long wings. The Bermuda petrel has a greyish-black crown and collar, dark grey upper-wings and tail, white upper-tail coverts and white under-wings edged with black, and the underparts are completely white.
The flora and fauna of Bermuda form part of a unique ecosystem due to Bermuda's isolation from the mainland of North America. The wide range of endemic species and the islands form a distinct ecoregion, the Bermuda subtropical conifer forests.
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 New Zealand owlet-nightjar is an extinct, comparatively large species of owlet-nightjar formerly endemic to the islands of New Zealand. Fossil remains indicate the species was once widespread across both the North Island and the South Island.
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 Bermuda hawk is an extinct bird of prey that was endemic to Bermuda. It was the sole member of the genus Bermuteo.
