Banded Whiteface
The banded whiteface (''Aphelocephala nigricincta'') is a species of bird in the family Acanthizidae. It is endemic to dryer regions of Australia. The ornithologist Alfred John North described the banded whiteface as ''Xerophila nigricincta'' in 1895, from specimens collected at Missionary Plains, Northern Territory. Harry Church Oberholser pointed out that this genus name was invalid as it had been given to a genus of mollusc, hence it gained its current name ''Aphelocephala nigricincta'' in 1899. Description The adult banded whiteface is around 10 cm (4 in) long. The upper parts of the body and head are greyish brown. The face has a white mask bordered by a darker band which runs vertically across the region of the eyes. The upper breast is pale blue-grey and the underparts white, separated by a prominent black band across the breast. There are red-brown patches on the flanks. The bill and legs are black and the eyes are white. The plumage of male and female are ali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strzelecki Track
Strzelecki Track is a mostly unsealed outback track in South Australia, linking Innamincka to Lyndhurst. History The track was pioneered by stockman, drover and cattle thief. Harry Readford, iin 1870, who stole drove 1,000 head of cattle and drove them down the track, selling them at Blanchewater Station and then fleeing to Adelaide. Pastoralists then used it as a stock route in the late 19th and early 20th centuries. After gas was discovered by Santos in the 1960s, it started carrying more traffic, as a route to Moomba, and some sections were sealed. Description The track links Innamincka to Lyndhurst through the Strzelecki Desert. It is mostly unsealed, but with a few short sealed sections to facilitate overtaking. It is passable to conventional vehicles during the dry season, although caution is required. The track is prone to flooding after heavy rains, and at other times the surface can be corrugated, with loose stones and dust. The Strzelecki Trac ...

Alfred John North
Alfred John North (11 June 1855 – 6 May 1917) was an Australian ornithologist. North was born in Melbourne and was educated at Melbourne Grammar School. He was appointed to the Australian Museum, Sydney in 1886 and was given a permanent position there five years later. He wrote a ''List of the Insectivorous Birds of New South Wales'' (1897) and a ''Descriptive Catalogue of the Nests and Eggs of Birds Found Breeding in Australia and Tasmania'' (1889) with George Barnard as co-author. He described a number of birds for the first time, many in the ''Victorian Naturalist'', the magazine of the Field Naturalists Club of Victoria of which he was a founding member. ReferencesNorth, Alfred John (1855 - 1917)at Bright Sparcs, University of Melbourne The University of Melbourne is a public research university located in Melbourne, Australia.

Bird
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. B ...

Acanthizidae
The Acanthizidae—known as Australian warblers—are a family of passerine birds which includes gerygones, the thornbills '' Acanthiza'', and the scrubwrens of '' Sericornis''. The Acanthizidae family consists of small to medium passerine birds, with a total length varying between . They have short rounded wings, slender bills, long legs, and a short tail. Most species have olive, grey, or brown plumage, although some have patches of a brighter yellow. The weebill is the smallest species of acanthizid, and the smallest Australian passerine; the largest is the pilotbird. Taxonomy and systematics Following the Sibley-Ahlquist taxonomy (1990) they were previously regarded as subfamily Acanthizinae within the family Pardalotidae. More recent molecular genetic studies do not support this arrangement. The Dasyornithidae (which include the bristlebirds) are variously seen either as subfamily Dasyornithinae within the family Acanthizidae or Pardalotidae or as own family (Schodde & Mas ...

Endemism
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 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 aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a 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 species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clutch (eggs)
__NOTOC__ A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in ''double-clutching''. The technique is used to double the production of a species' eggs, in the California condor case, specifically to increase population size. The act of putting one's hand in a nest to remove eggs is known as "dipping the clutch". Size Clutch size differs greatly between species, sometimes even within the same genus. It may also differ within the same species due to many factors including habitat, health, nutrition, predation pressures, and time of year. Clutch size variation can also reflect variation in optimal reproduction effort. In birds, clutch size can vary within a species due to various features (age and health of laying female, ability of male to supply food, and abundan ...

Torpor
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability. The term "torpor" can refer to the time a hibernator spends at low body temperature, lasting days to weeks, or it can refer to a period of low body temperature and metabolism lasting less than 24 hours, as in "daily torpor". Animals that undergo daily torpor include birds (even tiny hummingbirds, notably Cypselomorphae) and some mammals, including many marsupial species, rodent species (such as mice), and bats. During the active part of their day, such animals maintain normal body temperature and activity levels, but their metabolic rate and body temperature drop during a portion of the day (usually night) to conserve energy. Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is kno ...

Aphelocephala
''Aphelocephala'' is a genus of bird in the thornbill family Acanthizidae. The three species are collectively known as whitefaces. They are endemic to Australia, generally occurring in the arid centre of the continent. They are a striking looking bird, particularly compared to their duller looking relatives, having dark upperparts and white breasts and faces (as suggested by the name). Two species, the chestnut-breasted and banded whitefaces, break up the white undersides with a darker band (or double band). The three species have stubby bills and unlike the rest of the Acanthizidae they consume large numbers of seeds in their diet. The genus had been originally described as ''Xerophila'' by John Gould, however Harry Church Oberholser pointed out that this genus name had been given to a genus of mollusc. Hence he proposed the name ''Aphelocephala'' from the Ancient Greek ''aphelos'' "simple" and ''kephale'' (Latin:''caput'') "head". It contains the following species: * Southern ...

Endemic Birds Of Australia
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in birds. Patterns of endemism Family-level endemism is prominent in Australia. The Australasian biogeographic region has the highest number of endemic families of any zoogeographic region except the Neotropics, and many of these families are endemic to Australia itself — the country therefore stakes a strong claim to be the world's greatest hotspot of bird endemism. Australian endemic and near-endemic families The Australian endemic families are: * Emu (Dromaiidae), a well-known monotypic family; the emu is found in rural areas throughout the continent * Plains-wanderer (Pedionomidae), a monotypic family; plains-wanderer is restricted to arid inland areas in the southeast of Australia * Lyrebirds (Menuridae), two forest-dwelling species of southeast Australia * Scrub-birds (Atrichornithidae), two fore ...
