Chirruping Wedgebill
The chirruping wedgebill (''Psophodes cristatus'') is a medium-sized member of the genus ''Psophodes'', which consists or four to five songbirds endemic to Australia. Commonly found in low shrublands in south-eastern inland Australia, the species is distinguished by its distinctive, chirruping call. The chirruping wedgebill and chiming wedgebill (''Psophodes occidentalis'') were considered to be a single species until as late as 1973, when they were separated due to marked differences in their calls. Taxonomy John Gould originally described ''P. cristatus'' and ''P. occidentalis'' as one species (''Sphenostoma cristatum''), and this remained common practice until c. 1973. The separation of the species at that date was based mainly on differences in song and range. Description The chirruping wedgebill is a medium-sized bird, measuring approximately 18–21 cm and weighing 31-64 g. Its bill is dark and wedge-shaped when mature, and horn-coloured when immature.

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] |
Psophodes
''Psophodes'' is a genus of five species of songbirds endemic to Australia, known as whipbirds and wedgebills. Description Whipbirds and wedgebills are collectively recognised in the genus ''Psophodes''.Toon, A., Joseph, L., & Burbidge, A., (2013). Genetic analysis of the Australian whipbirds and wedgebills illuminates the evolution of their plumage and vocal diversity. ''Emu''. Vol. 113, pp. 359-366. Wedgebills are divided into the chirruping wedgebill (''Psophodes cristatus'') and the chiming wedgebill (''Psophodes occidentalis''). Whipbirds are divided into the eastern whipbird (''Psophodes olivaceus'') and the western whipbird (''Psophodes nigrogularis''). Subspecies of the western whipbird residing in Western Australia are known to be endangered. Barrett, R., (2013).

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluat ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Birds Described In 1838
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
