The unstreaked tit-tyrant (Uromyias agraphia) is a species of bird in the family Tyrannidae. It is endemic to Peru.
Its natural habitat is subtropical or tropical moist montane forests.
Penguins are a group of aquatic flightless birds from the family Spheniscidae of the order Sphenisciformes. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the ocean water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey.
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.
Buteo is a genus of medium to fairly large, wide-ranging raptors with a robust body and broad wings. In the Old World, members of this genus are called "buzzards", but "hawk" is used in the New World. As both terms are ambiguous, buteo is sometimes used instead, for example, by the Peregrine Fund.
The screamers are three South American bird species placed in family Anhimidae. They were thought to be related to the Galliformes because of similar bills, but are more closely related to ducks, and most closely related to the magpie goose. The clade is exceptional within the living birds in lacking uncinate processes of ribs. The three species are: The horned screamer ; the southern screamer or crested screamer ; and the northern screamer or black-necked screamer.
A booby is a seabird in the genus Sula, part of the family Sulidae. Boobies are closely related to the gannets (Morus), which were formerly included in Sula.
The Scottish crossbill is a small passerine bird in the finch family Fringillidae. It is endemic to the Caledonian Forests of Scotland, and is the only terrestrial vertebrate species endemic to the United Kingdom. The Scottish crossbill was confirmed as a unique species in August 2006, on the basis of having a distinctive bird song.
Accipiter is a genus of birds of prey in the family Accipitridae. With 49 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although with the exception of the American goshawk almost all New World species are simply known as "hawks". They can be anatomically distinguished from their relatives by the lack of a procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus Hieraspiza.
The snowcocks or snowfowl are a group of bird species in the genus Tetraogallus of the pheasant family, Phasianidae. They are ground-nesting birds that breed in the mountain ranges of southern Eurasia from the Caucasus to the Himalayas and western China. Some of the species have been introduced into the United States. Snowcocks feed mainly on plant material.
The desert sparrow is a species of bird in the sparrow family Passeridae, found in the Sahara Desert of northern Africa. A similar bird, Zarudny's sparrow, is found in Central Asia and was historically recognised as a subspecies of the desert sparrow, but varies in a number of ways and is now recognised as a separate species by BirdLife International, the IOC World Bird List, and the Handbook of the Birds of the World Alive.
The Sunda scops owl is a small brown owl native to the Sunda Islands.
This article is a list of biological species, subspecies, and evolutionary significant units that are known to have become extinct during the Holocene, the current geologic epoch, ordered by their known or approximate date of disappearance from oldest to most recent.
The Biak monarch, or Biak monarch flycatcher, is a species of bird in the family Monarchidae. It is endemic to Biak Island, Indonesia.
The rufous monarch, or rufous monarch flycatcher, is a species of bird in the family Monarchidae found in western New Guinea. Its natural habitat is subtropical or tropical moist lowland forests.
Uromyias is a genus of small Andean, tyrant flycatchers known as tit-tyrants. They were formerly recognized based on syrinxial and plumage characters, including a flatter crest and a longer tail, but was included within Anairetes due to genetic analysis. Recent analyses suggested splitting into Uromyias again.
