Eyrean Grasswren
The Eyrean grasswren (''Amytornis goyderi'') is a small grasswren from the Passerine family Maluridae. This is a cryptically plumaged and uncommon bird endemic to arid regions of Central Australia. The species was discovered by F.W. Andrews in 1874 around the Macumba River at Lake Eyre, and named after the South Australian Surveyor General George Woodroffe Goyder. Description At 14–16.5 cm in length, ''Amytornis goyderi'' is the smallest grasswren. It has a deep, finch-like bill. There are some minor differences between sexes, and between populations across the distribution. Adult male The head is reddish with bold white streaks, neck and upper body dull to bright rufous-brown, streaked with fine dark and white lines. The face is mainly white except for the rufous forehead, white lores and a thin partial white eye-ring beneath the eye; and sometimes a rufous fore- supercilium. Black and white ear coverts separate the dark head parts from the off-white chin and throa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fledge
Fledging is the stage in a flying animal's life between hatching or birth and becoming capable of flight. This term is most frequently applied to birds, but is also used for bats. For altricial birds, those that spend more time in vulnerable condition in the nest, the nestling and fledging stage can be the same. For precocial birds, those that develop and leave the nest quickly, a short nestling stage precedes a longer fledging stage. All birds are considered to have fledged when the feathers and wing muscles are sufficiently developed for flight. A young bird that has recently fledged but is still dependent upon parental care and feeding is called a fledgling. People often want to help fledglings, as they appear vulnerable, but it is best to leave them alone. The USA National Phenology Network defines the phenophase (or life cycle stage) of fledged young for birds as "One or more young are seen recently departed from the nest. This includes young incapable of sustained fli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Witjira National Park
Witjira National Park is a protected area in the Australian state of South Australia about north of the state capital of Adelaide. History The national park was proclaimed on 21 November 1985 to "protect Australia’s largest array of artesian springs: the nationally significant Dalhousie Mound Springs complex". In 2007, it became the first protected area in South Australia to have formal joint management arrangements between its traditional owners and the Government of South Australia. The extent of land occupied by the national park was gazetted as a locality in April 2013 under the name "Witjira". On 26 November 2021, the government changed the conditions of the park, to forever exclude mining in the Dalhousie Springs National Heritage Area.

Simpson Desert
The Simpson Desert is a large area of dry, red sandy plain and dunes in the Northern Territory, South Australia and Queensland in central Australia. It is the fourth-largest Deserts of Australia, Australian desert, with an area of . The desert is underlain by the Great Artesian Basin, one of the largest inland drainage areas in the world. Water from the basin rises to the surface at numerous natural springs, including Dalhousie Springs, and at Water well, bores drilled along stock routes, or during petroleum exploration. As a result of exploitation by such bores, the flow of water to springs has been steadily decreasing in recent years. It is also part of the Lake Eyre basin. The Simpson Desert is an erg (landform), erg that contains the world's longest parallel sand dunes. These north-south oriented dunes are static, held in position by vegetation. They vary in height from in the west to around on the eastern side. The largest dune, Nappanerica or Big Red, is in height. Hi ...

Amytornis Purnelli
The dusky grasswren (''Amytornis purnelli'') is a species of small passerine bird in the family Maluridae. The species is endemic to Australia but is limited to inland areas of the Northern Territory, Western Australia and South Australia. Description The dusky grasswren is superficially similar in appearance to a number of the other grasswrens in the genus ''Amytornis'', but is the only member of this genus to exclusively inhabit rocky ranges across Central Australia. It has a predominantly brown base colour to its plumage with fine pale streaking over the head breast and mantle. The brown of the plumage is a richer chestnut on the back and pale to almost buff on the belly and vent. The most obvious difference between sexes is the bright rusty-brown spot on the fore-flanks of the adult female and all birds exhibit the characteristic cocked tail posture common to all malurids. Field identification The species is easily identified within its core range by its distinctive vocalisa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amytornis Ballarae
The Kalkadoon grasswren (''Amytornis ballarae''), also called the Ballara grasswren, is a species of passerine bird in the family Maluridae. It is endemic to Australia. Taxonomy It was formerly treated as a subspecies of the dusky grasswren. The English qualifier ‘ Kalkadoon’ refers to the name of the Aboriginal group that live in the area where it is found. The specific epithet ''ballarae'' refers to the deserted mining town of Ballara, in north-western Queensland between Mount Isa and Cloncurry. Description It is similar to the dusky grasswren, though the markings are generally brighter and more defined, e.g. the wing coverts and remiges are grayish with a small rufous patch at the base of the outer remiges, compared with the same parts of the dusky grasswren being a uniformly dull rufous-brown. Distribution and habitat The Kalkadoon grasswren has a restricted range, being endemic to spinifex covered hills in the Selwyn Range system of north-west Queensland. Reference ...

Western Grasswren
The western grasswren (''Amytornis textilis''), also referred to as the thick-billed grasswren (western subspecies) and, formerly, as the textile wren, is a species of bird in the family Maluridae. It is endemic to Australia. It was formerly lumped as the nominate subspecies of the thick-billed grasswren. History The species, indeed the genus, was first collected in 1818 on Shark Bay’s Peron Peninsula, in northwest Western Australia, by Jean René Constant Quoy and Joseph Paul Gaimard, naturalists with Louis de Freycinet's circumnavigational exploring expedition in the French corvette ''Uranie''. Although the original specimen was apparently lost with the shipwreck of the ''Uranie'' in the Falkland Islands, it had been illustrated by expedition artist Jacques Arago and was described (as ''Malurus textilis'') by Dumont in 1824. Description A species of ''Amytornis'', the western grasswren is a small, shy, mainly terrestrial bird. It has brown plumage, finely streaked with bl ...
