Gerygone Flaviventris, Gray
''Gerygone'' (), the gerygones or peep-warblers, is a genus of bird in the family Acanthizidae. The genus ranges from Southeast Asia through New Guinea and Australia to New Zealand and the Chatham Islands. Most of the species are found in Australia and New Guinea; only one, the golden-bellied gerygone, has managed to cross Wallace's Line and colonise as far as Thailand, Malaysia and the Philippines. Gerygones are insectivores which obtain most of their food by gleaning and snatching in the foliage of trees and bushes. They are small, mostly weighing an average of 6–7 g, and show little variation in size across their range, except for the insular Chatham gerygone, which is nearly twice as large as the rest of the genus. Their songs are described as "simple but delightful", many descending in pitch, and some species are excellent mimics. "Gerygone" means "born of sound" (Magrath 2003). The genus contains 20 species including one which is now extinct: * Brown gerygone, ''Gery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairy Gerygone
The fairy gerygone (''Gerygone palpebrosa''), previously known as the fairy warbler, is a species of bird in the family Acanthizidae native to New Guinea and Queensland. Taxonomy Alfred Russel Wallace described the species as ''Gerygone palpebrosa'' in 1865, from a specimen from the Aru Islands. The species name is derived from the Latin ''palpebra'' "eyelid", for the bird's facial markings. A taxon known commonly as the fairy warbler, ''Gerygone flavida'' was described from the Herbert River in Queensland and initially treated as a separate species. However, birds further north along the Queensland coastline became gradually more like ''Gerygone palpebrosa'', indicating there was no delineation between the two forms. This and the similarity of their songs indicated they were a single species. Other common names recorded include black-throated, black-headed or masked gerygone, warbler or flyeater, hornet-nest bird, from a propensity to nest near wasp nests. These names were appli ...

Brown Gerygone
The brown gerygone (''Gerygone mouki''), previously known as the brown warbler, is a small passerine bird native to eastern coastal Australia. The upper parts of the brown gerygone are a deep olive-grey or olive-brown, while its face and underparts are a much paler grey, cream, or washed-out brown. The tail feathers are dark and may be white-tipped. It is approximately 10 cm in length. The brown gerygone has a relatively large range. Although total population trends have not been quantified, it is considered of "least concern" by the IUCN. It may be sighted in coastal rainforest, singly or in small groups of two to four. It feeds on insects. The brown gerygone call is a soft ''what-is-it''. It is not closely related to either true Old World Warblers or the New World Warblers, but belongs rather to the Corvida parvorder comprising many tropical and Australian passerines, as well as crow A crow is a bird of the genus ''Corvus'', or more broadly a synonym for all of ''Corvus ...

Western Gerygone
The western gerygone (''Gerygone fusca'') is a small, brownish-grey species of passerine bird, which is found in inland and Southwest Australia, south-west Australia. It is an arboreal, insectivore of open forest, woodland and dry shrubland. It is not currently threatened with extinction (IUCN Red List, IUCN: Least-concern species, Least Concern). Systematics and taxonomy The western gerygone is a member of the family Acanthizidae (Thornbills and Allies), which has been split from the family Pardalotidae (Pardalotes). It is a Sister species, sister-species to the mangrove gerygone (''Gerygone levigaster''). The close relationship of this Phylogenetic tree, phylogenetic pair is suggested by analyses of both Morphology (biology), morphological characteristics and genetic loci. Populations of a common ancestor of the two species are thought to have divergent evolution, diverged after becoming fragmented by severe aridity during the Pleistocene. These two species are now in seco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mangrove Gerygone
The mangrove gerygone (''Gerygone levigaster'') is a species of bird in the Australian warbler family Acanthizidae. The species is also known as the mangrove warbler. The species is thought to form a superspecies with the closely related fan-tailed gerygone of Melanesia and the Australian western gerygone. There are three subspecies of mangrove gerygone, ''G. l. pallida'', found in southern New Guinea, the nominate race ''G. l. levigaster'', which is found from coastal Western Australia to coastal north Queensland, and ''G. l. cantator'', which is found from coastal Queensland to New South Wales. The species is uncommon in New Guinea and has suffered some declines due to mangrove clearances but is not considered threatened by the IUCN. The species is principally distributed in mangrove forests and in forests and woodland adjacent to mangroves. The species will move into nearby forests from mangroves to feed, particularly in the breeding season. Where its range overlaps with that ...

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] |
