The '''Gang-gang Cockatoo''', ''Callocephalon fimbriatum,'' is found in the cooler and wetter forests and woodlands of [[Australia]], particularly [[alpine]] [[bushland]]. Mostly mid 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 '''Long-billed Corella''', ''Cacatua tenuirostris'', is a [[cockatoo]] native to [[Australia]]. Species are mostly white, with a pink face and forehead. They also have faintly pink feathers on the breast and belly, and yellow on the underside of the wings and tail. The birds have a long white beak, which is used to dig for roots and [[seed]]s.

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.

Long-billed Corellas measure about 40cm in length and have a wingspan of about 80-90cm.

Like all [[cockatoo]]s, Gang-gangs nest in hollow trees. Loss of older, hollow-bearing 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.

The species has a small distribution, and usually inhabits woodlands, river banks and farming land, though it is not uncommon in urban areas.

This 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.

The Long-billed Corella, Cacatua tenuirostris, is a cockatoo native to Australia. Species are mostly white, with a pink face and forehead. They also have faintly pink feathers on the breast and belly, and yellow on the underside of the wings and tail. The birds have a long white beak, which is used to dig for roots and seeds.

Long-billed Corellas measure about 40cm in length and have a wingspan of about 80-90cm.

The species has a small distribution, and usually inhabits woodlands, river banks and farming land, though it is not uncommon in urban areas.

Corellas as Pets

Long-billed Corellas are also popular as pets in many parts of Australia. Although they were once uncommon as pets, their population has stabilised in the last decade.
