The '''Golden-shouldered Parrot''' (''Psephotus chrysopterygius'') is a rare [[Aves|bird]] of southern [[Cape York Peninsula]], in [[Queensland]], [[Australia]]. A small attractive [[parrot]] related to the more common [[Red-rumped Parrot]], it is considered to be a [[superspecies]] with the [[Hooded Parrot]] ''(P. dissimilis)'' of the [[Northern Territory]] and the apparently [[Extinction|extinct]] [[Paradise Parrot]] of [[Queensland]] and [[New South Wales]]. It measures 26 cm long and weighs between 54-56 g.

The '''Gang-gang Cockatoo''', ''Callocephalon fimbriatum,'' is found in the cooler and wetter forests and woodlands of [[Australia]], particularly [[:wikt:alpine|alpine]] [[bushland]]. Mostly mild grey in colour with some lighter scalloping (more pronounced and buffish in females) the male has a red head and [[crest (bird)|crest]], while the female has a small fluffy grey crest. It ranges throughout south-eastern Australia and [[Tasmania]]. The Gang-gang Cockatoo is the faunal emblem of the [[Australian Capital Territory]]. It is easily identified by its distinctive call, which is described as resembling a creaky gate, or the sound of a cork being pulled from a wine bottle.  
  
The Golden-shouldered Parrot lives in open forest, where it feeds on small grass [[seed]]s, principally those of [[firegrass]]. An important [[habitat (ecology)|habitat]] requirement is the provision of terrestrial [[Termite|termite mounds]], which the bird uses for nesting in. This has led to the parrot also being known as the Antbed Parrot. They will preferentially seek out taller mounds (up to 2 m high), and will dig a burrow into them when the mound has been softened by the rains. A long tunnel is dug down into the mound, and capped off by a nesting chamber. The clutch size is between 3-6 [[Egg (biology)|egg]]s, which are [[incubate]]d for 20 days. The mound regulates the temperature in the chamber, keeping it high enough that the eggs can be left unattended while the parents feed.
+
The name ''Gang-gang'' comes from a [[New South Wales]] [[Indigenous Australian|Aboriginal]] language, either [[Ngunnawal]] or [[Wiradjuri]]. It is possible both language groups called it that.
  
The Golden-shouldered Parrot is listed as [[Endangered species|endangered]] ([[CITES]] I). The species has a restricted range and suffers from a variety of threats, including predation by [[feral cat]]s, [[tourist]] disturbance, and a change in burning regime in the grasslands upon whose seeds it depends. The wild population is around 3000 birds, with around 1500 held in captivity in Australia.

Unlike most other [[cockatoo]]s, Gang-gangs nest in young, solid trees, the females using their strong bills/beaks to excavate nesting cavities. Lots of older, hollow trees and loss of feeding habitat across south-eastern Australia through land clearing has led to a significant reduction in the numbers of this cockatoo in recent years.

This particular species was most often allied with the white cockatoos of the genus ''[[Cacatua]]''.

Template:Taxobox

The Gang-gang Cockatoo, Callocephalon fimbriatum, is found in the cooler and wetter forests and woodlands of Australia, particularly alpine bushland. Mostly mild grey in colour with some lighter scalloping (more pronounced and buffish in females) the male has a red head and crest, while the female has a small fluffy grey crest. It ranges throughout south-eastern Australia and Tasmania. The Gang-gang Cockatoo is the faunal emblem of the Australian Capital Territory. It is easily identified by its distinctive call, which is described as resembling a creaky gate, or the sound of a cork being pulled from a wine bottle.

The name Gang-gang comes from a New South Wales Aboriginal language, either Ngunnawal or Wiradjuri. It is possible both language groups called it that.

Unlike most other cockatoos, Gang-gangs nest in young, solid trees, the females using their strong bills/beaks to excavate nesting cavities. Lots of older, hollow trees and loss of feeding habitat across south-eastern Australia through land clearing has led to a significant reduction in the numbers of this cockatoo in recent years.

This particular species was most often allied with the white cockatoos of the genus Cacatua. This has always been controversial due to the unusual appearance and coloration of the bird, especially its sexual dichromatism. New research has finally resolved the matter, with the Gang-gang Cockatoo being recognized as a distinctive early offshoot of the calyptorhynchine (dark) cockatoos (Brown & Toft, 1999). Considering the robust phylogeny of the cockatoos now established, a comparison of characters gained and lost during the evolution of cockatoos suggests that the Gang-gang Cockatoo - while of course much changed and adapted during the maybe 20 million years since its last common ancestor with any other living species lived - is probably still very similar in overall appearance to how the earliest cockatoos would have looked, and certainly the most primitive-looking of the species alive today.
