Yinberrie Hills Important Bird Area
The Yinberrie Hills Important Bird Area comprise some 1050 km2 of rocky, tropical savanna covered, wooded hills in the lower Top End of the Northern Territory of Australia. They lie 45 km north of the town of Katherine, and about the same distance south of Pine Creek. The site is important for Gouldian finches. Description The site is bounded by Nitmiluk National Park and the Arnhem Land Plateau in the east. It consists of rolling hills with thin, sandy loam soils overlaid by angular cobbles. The hills are covered by smooth-barked eucalypts with an understorey of native grasses. They are drained by a network of ephemeral streams which retain water through the dry season in small, scattered pools. Mean annual rainfall in the area is about 1000 mm, falling mainly from December to March. Key features of the habitat for the finches are that the lack of grazing, and few extensive hot fires, allow native grasses to seed; the persistent waterholes provide drinki ...

Wet Season
The wet season (sometimes called the Rainy season) is the time of year when most of a region's average annual rainfall occurs. It is the time of year where the majority of a country's or region's annual precipitation occurs. Generally, the season lasts at least a month. The term ''green season'' is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is or more. In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.Elisabeth M.

Banded Honeyeater
The banded honeyeater (''Cissomela pectoralis'') is a species of honeyeater in the family Meliphagidae with a characteristic narrow black band across its white underparts. It is endemic to tropical northern Australia. Taxonomy and systematics The scientific name for the banded honeyeater is ''Cissomela pectoralis (''Gould, 1841). The holotype was Holotype ANSP 18224 male, Australia: north coast, held in the Academy of Natural Sciences of Drexel University, Philadelphia. The banded honeyeater was previously placed in the genus '' Certhionyx'', but was moved to the monotypic genus '' Cissomela'' after a molecular phylogenetic analysis, published in 2011, showed that the original genus was polyphyletic. The genus name ''Cissomela'' (Bonaparte, 1854) means "honey magpie" from the Greek ''kissa'' for 'magpie', thus referring to the black and white colouring, and ''mela'' meaning 'honey' for its feeding habits. The specific epithet ''pectoralis'' comes from the Latin ''pectoris'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hooded Parrot
The hooded parrot (''Psephotellus dissimilis'') is a species of parrot native to the Northern Territory in Australia. It is found in savannah and open woodland and is one of two extant species in its genus that breed in termite mounds. It has declined from much of its original range. Taxonomy One of three species known as antbed parrots, the hooded parrot is closely related to (and sometimes considered a subspecies of) the golden-shouldered parrot (''Psephotellus chrysopterygius''). A genetic study revealed its ancestors most likely diverged from ancestors of the latter species in the late Miocene or early Pliocene at the conclusion of the 'Hill Gap'. Norwegian naturalist Robert Collett described the hooded parrot in 1898. Its species name is the Latin word ''dissimilis'' "different" and either refers to its sexual dimorphism or its different appearance from its closest relative. Black-hooded parrot is an alternative name. Description The hooded parrot is a medium-sized parro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Rosella
The northern rosella (''Platycercus venustus''), formerly known as Brown's rosella or the smutty rosella, is a species of parrot native to northern Australia, ranging from the Gulf of Carpentaria and Arnhem Land to the Kimberley. It was described by Heinrich Kuhl in 1820, and two subspecies are recognised. The species is unusually coloured for a rosella, with a dark head and neck with pale cheeks—predominantly white in the subspecies from the Northern Territory and blue in the Western Australian subspecies ''hillii''. The northern rosella's mantle and scapulars are black with fine yellow scallops, while its back, rump and underparts are pale yellow with fine black scallops. The long tail is blue-green, and the wings are black and blue-violet. The sexes have similar plumage, while females and younger birds are generally duller with occasional spots of red. Found in woodland and open savanna country, the northern rosella is predominantly herbivorous, consuming seeds, particular ...

Varied Lorikeet
The varied lorikeet (''Psitteuteles versicolor''), is a species of parrot in the family Psittacidae that is endemic to the northern coastal regions of Australia. It is the only species in the genus ''Psitteuteles''. Taxonomy The first depiction of the species was included in a seminal folio by Edward Lear, the subject of his illustration has since been lost and it became recognised as the holotype. The image was published as the thirty sixth lithographic plate in September 1831, without a location or description, in his work ''Illustrations of the Family of Psittacidae, or Parrots'' (1830–32) depicting live specimens in English zoological exhibitions and private collections. The name supplied in the caption was ''Trichoglossus versicolor'', with the subheading "Variegated Parrakeet". The source of the specimen, according to Richard Schodde (1997), was incorrectly determined as "Cape York", a location proposed by Gregory Mathews in 1912 and subsequently repeated. Schodde repor ...

Bush Stone-curlew
The bush stone-curlew or bush thick-knee, also known as the Iben bird (''Burhinus grallarius'', obsolete name ''Burhinus magnirostris'') is a large, ground-dwelling bird endemic to Australia. Its favoured habitat is open plains and woodlands, where it stalks slowly at night in search of invertebrates such as insects. Its grey-brown coloration is distinguished by dark streaks, its eyes are large and legs are long. It is capable of flight, but relies on the camouflage of its plumage to evade detection during the day; the bush curlew adopts a rigid posture when it becomes aware of an observer. Both sexes care for two eggs laid on the bare ground, usually sited near bush in a shaded position or next to a fallen branch. Taxonomy The bush stone-curlew was first described by English ornithologist John Latham in 1801 under the binomial name ''Charadius grallarius''. Latham published three names simultaneously; however, the seniority of ''C. grallarius'' follows the publication of the nam ...

Chestnut-backed Buttonquail
The chestnut-backed buttonquail (''Turnix castanotus'') is a species of bird in the family Turnicidae. It is endemic to Australia. Taxonomy John Gould described the species in 1840, from a specimen collected by Benjamin Bynoe, ship's surgeon of , from northwestern Australia, as ''Hemipodius castanotus''. English zoologist George Gray placed it in the genus ''Turnix'' in 1870. William Robert Ogilvie-Grant corrected the name to ''Turnix castanonota'' in 1889. Three subspecies were described by Gregory Mathews, but all are now considered as invalid and merely individual variants. Etymology "Chestnut-backed buttonquail" has been designated the official name by the International Ornithologists' Union (IOC). The species name is derived from the Ancient Greek words ''kastanon'' "chestnut" and ''noton'' "back". Gould called it "chestnut-backed hemipode" in 1848, noting the colonists called it "thick-billed quail". The buttonquail species were generally known as "quail" (hence "chestnut ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
