Stephanoaetus Coronatus
The crowned eagle, also known as the African crowned eagle or the crowned hawk-eagle (''Stephanoaetus coronatus''), is a large bird of prey found in sub-Saharan Africa; in Southern Africa it is restricted to eastern areas.Sinclair & Ryan (2003). ''Birds of Africa south of the Sahara''. Its preferred habitats are principally riparian woodlands and various forests. The crowned eagle is the only extant member of the genus ''Stephanoaetus''. A second species, the Malagasy crowned eagle (''Stephanoaetus mahery'') became extinct after humans settled on Madagascar.Goodman, Steven M. (1994).

Stephanoaetus Mahery
The Malagasy crowned eagle (''Stephanoaetus mahery''), also known as the Madagascar crowned hawk-eagle, is an extinct large bird of prey endemic to Madagascar. It has been proposed that this bird, combined with elephant bird eggs, were the source of sightings of the mythical Roc. Description It may have been comparable in average size to the related African crowned eagle, but possibly slightly larger, with the largest female weights estimated at up to , or about the size of a large female golden eagle. Ecology It probably fed on lemurs. The raptor avoidance behaviour exhibited by contemporary adult lemurs may have originated in response to this (and another now-extinct Malagasy '' Aquila'') eagle; extant Malagasy raptors appear to be a threat primarily to juvenile members of the large diurnal lemur species. It was perhaps an apex predator of the Malagasy forests, along with the giant fossa and the ''Voay'' crocodile. It likely became extinct in the 16th century due to huma ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Genera With One Living Species
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Biological Society Of Washington
The Biological Society of Washington is a worldwide acting scientific organisation established on 3 December 1880 in Washington, D.C., United States. The original purpose was "to encourage the study of the Biological Sciences and to hold meetings at which papers shall be read and discussed." The current primary function is "the furtherance of taxonomic study and the diffusion of taxonomic knowledge." In May 1882 the first issue of the peer reviewed journal ''Proceedings of the Biological Society of Washington'' was published. Since then it appears quarterly. Another journal is the ''Bulletin of the Biological Society of Washington'' which is published since 1918 and contains larger studies, symposia proceedings and special study collections. The Biological Society of Washington was among the eight organisations which founded the Washington Academy of Sciences in 1898. The governing council of the society includes the elected officers and selected local members. The first elected pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The moose (''Alces alces'') is an extant species, and the dodo (''Raphus cucullatus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species ("Lazarus species"), or if previously-known extant species are reclassified as members of the taxon. Most biologists, zoologists, and botanists are in practice neontologists, and the term neontologist is used large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
