Black Grasswren
The black grasswren (''Amytornis housei''), known as dalal to the Wunambal people, is a species of bird in the family Maluridae. It is endemic to Western Australia. Naturalist Frederick Maurice House discovered the black grasswren in 1901, as a part of a surveying party led by Frederick Slade Drake-Brockman through the Kimberley in northwestern Australia. He collected a single specimen. Alexander William Milligan, consulting ornithologist at the Western Australian Museum, named it after House when he described the species. The bird was not seen again until 1968, when Dan Freeman of the Natural History Museum led a party to the same area to find it. Its natural habitat is Mediterranean-type shrubby vegetation and open woodland, punctuated by large sandstone boulders and slabs. It inhabits the Mitchell River National Park in the Kimberley region of north-west WA. It has been classified as least concern. Bushfires have become more frequent, as has rainfall, which has altered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander William Milligan
Alexander William Milligan (1858 – 30 March 1921) was an Australian accountant, legal clerk, zoological collector and ornithologist. Milligan was born at Sulky Gully, near Ballarat in Victoria. He was educated at Guildford, Victoria. In 1897 he moved to Western Australia where he worked as a temporary accountant with the Department of Lands and Surveys. He was a founding member in 1901 of the Royal Australasian Ornithologists Union, with which he served as a member of the Checklist Committee. He was also the Honorary Consulting Ornithologist to the Western Australian Museum. In 1908 he moved back to Victoria where he died in St Kilda. Several birds were named after him by Gregory Mathews Gregory Macalister Mathews Order of the British Empire, CBE FRSE FZS FLS (10 September 1876 – 27 March 1949) was an Australian-born amateur ornithologist who spent most of his later life in England.

Boulder
In geology, a boulder (or rarely bowlder) is a rock fragment with size greater than in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks or stones. The word ''boulder'' derives from ''boulder stone'', from the Middle English ''bulderston'' or Swedish ''bullersten''.

Birds Described In 1902
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Western Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus, Cytisus aeolicus'' is an endemite of the Italian flora. ''Enidae, Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a Invasive species, non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a specie ...

Amytornis
Grasswrens (''Amytornis)'' are a genus of birds in the Australasian wren family, Maluridae. Taxonomy and systematics ''Amytornis'' is the only genus classified within the subfamily Amytornithinae, and form a separate clade than the related fairy-wrens and emu-wrens within the family Maluridae. The genus contains thirteen species, many of which are poorly known due to their secretive nature and remote and inaccessible habitat. Extant species The genus contains the following species: Description Grasswrens are the largest members of the Australasian wren family, ranging from for the Eyrean grasswren to the white-throated grasswren. They generally have long tails and legs and short wings and are adapted for life foraging on the ground. The bill is typically shorter and narrower than the fairy-wrens and emu-wrens, which reflects the larger part that seeds play in their diet. The plumage of the grasswrens is cryptic, usually red, buff and brown patterned with white and black. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triodia Pungens
''Triodia pungens'', commonly known as soft spinifex, is a species of grass native to northwestern Australia. The plant is currently being researched due to its resinous properties as a Termite timber coating. Other research and applications are as a latex enhancer and bitumen adhesive. In its natural habitat, the Spinifex is used by local Indigenous people as a weapon and housing adhesive. Originally described by botanist Robert Brown in his 1810 work ''Prodromus Florae Novae Hollandiae ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' (Prodromus of the Flora of New Holland and Van Diemen's Land) is a flora of Australia written by botanist Robert Brown and published in 1810.

Australian Wildlife Conservancy
The Australian Wildlife Conservancy (AWC) is an Australian independent, nonprofit organisation, working to conserve threatened wildlife and ecosystems in Australia. This is principally achieved through the acquisition of extensive areas of land on which to establish conservation reserves ("sanctuaries") or by entering into partnerships with government, Indigenous groups, and private landholders to manage landscapes for effective conservation. AWC is the largest private owner and manager of land for conservation in Australia, currently managing 31 sanctuaries and partnership sites for wildlife conservation that cover over 6.5 million hectares of land across Australia. Australian Wildlife Conservancy operate under a unique model for conservation, using science (predominantly biodiversity survey work and targeted research) to inform on-ground land management, such as control of fire, feral animals and weeds. There is a strong focus on wildlife conservation: consequently, about 80% o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bushfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurrence of wildfires throughout the history of terrestrial life invites conjecture that fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitchell River National Park (Western Australia)
Mitchell River National Park is a national park in the Kimberley region of Western Australia, northeast of Perth. The park adjoins the northern boundary of the Prince Regent National Park. The nearest towns are Derby, to the southwest, as well as Wyndham, to the southeast. Created in 2000, the park covers an area of over on the Mitchell Plateau (Ngauwudu). The two main features of the park are Mitchell Falls (a waterfall on the Mitchell River) and Surveyors Pool (or Aunauyu). It lies in the traditional lands of the Wunambal, an Aboriginal Australian people. The park is known for distinctive plants such as a species of fan palm; it is home to several significant and threatened species, including the tiny rock wallaby known as the monjon and the black grasswren. A new Kimberley National Park, which would encompass Mitchell River National Park, Prince Regent National Park and Lawley River National Park, was in the early stages of planning around 2015 by Colin Barnett's go ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
