Guam Flycatcher
The Guam flycatcher (''Myiagra freycineti''), or Guam broadbill, is an extinct species of bird in the family Monarchidae formerly endemic to Guam. Taxonomy and systematics Some authorities consider the Guam flycatcher to have been a subspecies of the Oceanic flycatcher. It has also been considered conspecific with the Pohnpei flycatcher and Palau flycatcher. Alternate names for the Guam flycatcher include Guam Myiagra, Guam Myiagra flycatcher, Marianne Islands flycatcher, Micronesian broadbill, and Micronesian Myiagra. Description The Guam flycatcher was a small bird measuring 5 inches (13 cm) long with different coloration for the males and females. Males were glossy blue-black above while females were brownish-gray. Both had white below and buff coloration on the breast. It had a wide bill with long “whiskers” which helped it locate its food. Status The bird was secretive and occurred mainly in limestone and ravine forests. Although common on Guam as recently as the e ...

Naturalis Biodiversity Center - RMNH
Naturalis Biodiversity Center ( nl, Nederlands Centrum voor Biodiversiteit Naturalis) is a national museum of natural history and a research center on biodiversity in Leiden, Netherlands. It was named the European Museum of the Year 2021. Although its current name and organization are relatively recent, the history of Naturalis can be traced back to the early 1800s. Its collection includes approximately 42 million specimens, making it one of the largest natural history collections in the world. History The beginnings of Naturalis go back to the creation of the Rijksmuseum van Natuurlijke Historie (abbreviated RMNH, National Museum of Natural History) by Dutch King William I on August 9, 1820. In 1878, the geological and mineralogical collections of the museum were split off into a separate museum, remaining distinct until the merger of the Rijksmuseum van Natuurlijke Historie with the Rijksmuseum van Geologie en Mineralogie (abbreviated RGM) in 1984, to form the Nationaal N ...

Birds Described In 1881
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extinct Birds Of Oceania
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] |

Myiagra
''Myiagra'' is a genus of passerine birds in the family Monarchidae, the monarch flycatchers, native to Australasia, sometimes referred to as the broad-billed flycatchers or simply broadbills. Taxonomy The genus ''Myiagra'' was introduced in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield. The name combines the Ancient Greek ''muia'' meaning "a fly" and ''agreō'' meaning "to seize". Myiagros was also the name of a Greek god. The type species was designated by George Robert Gray in 1840 as the leaden flycatcher. Species The genus contains 22 species include one that is now extinct: * Oceanic flycatcher (''Myiagra oceanica'') * Palau flycatcher (''Myiagra erythrops'') * † Guam flycatcher (''Myiagra freycineti'') (extinct) * Pohnpei flycatcher (''Myiagra pluto'') * Moluccan flycatcher (''Myiagra galeata'') * Biak black flycatcher (''Myiagra atra'') * Leaden flycatcher (''Myiagra rubecula'') * Steel-blue flycatcher (''Myiagra ferrocyanea'') * Makira flyc ...

Brown Tree Snake
The brown tree snake (''Boiga irregularis''), also known as the brown catsnake, is an arboreal rear-fanged colubrid snake native to eastern and northern coastal Australia, eastern Indonesia (Sulawesi to Papua), Papua New Guinea, and many islands in northwestern Melanesia. This snake is infamous for being an invasive species responsible for extirpating the majority of the native bird population in Guam. It is also one of the very few colubrids found in Australia, where elapids are more common. Diet The brown tree snake preys upon birds, lizards, bats, and rats and other small rodents in its native range. It preys on birds and shrews in Guam.Pianka, Eric R.; King, Dennis; King, Ruth Allen.

Conspecies
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
