The '''Palm Cockatoo''', ''Probosciger aterrimus'', is a large black [[Psittaciformes|parrot]] of the [[cockatoo]] family and this species is unique in its kind. It is the only species in its genus (''''' Probosciger''''') and subfamily ('''Microglossinae''') and its unique position within the cockatoo family has been confirmed by molecular studies<ref>Brown, D.M. and C.A. Toft. 1999. ''Molecular systematics and biogeography of the cockatoos (Psittaciformes: Cacatuidae).'' [[The Auk]] 116(1):141-157</ref>. It is found in northern [[Queensland]] and [[New Guinea]]. It measures around 55-60 cm in length and weighs between 500-1,000 g. It is a distinctive [[Aves|bird]] with a large [[Crest (bird)|crest]] and one of the largest bills of any parrot (only the [[Hyacinth Macaw]]'s is larger). The bill is also unusual as the lower and upper mandibles do not meet for much of its length, allowing the tongue to hold a nut against the top mandible while the lower mandible works to open it. The Palm Cockatoo also has a distinctive red gape that changes colour when the bird is alarmed or excited.

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, 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 Palm Cockatoo makes four different kinds of vocalisations. It also has a unique display where the bird drums a large branch against a dead bough or tree, creating a loud noise that can be heard up to 100 m away.

Unlike most [[cockatoo]]s, Gang-gangs nest in solid trees, into which they excavate a nesting cavity with their powerful bills. Lots of older, dead, 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.

The Palm Cockatoo is currently listed under least concern by the [[IUCN]] <ref>[http://redlist.org/search/details.php?species=18187&tab=summ IUCN Redlist]: Probosciger aterrimus</ref> while the species is listed on [[CITES]] as ''Lower Risk - near threatened''<ref>[http://www.cites.org/eng/resources/species.html CITES website search page]</ref> This species is in high demand for the pet trade due to its unusual appearance, and does not breed well in captivity, requiring the removal of wild birds. It is still relatively common in [[Cape York]], but is threatened there by [[habitat (ecology)|habitat]] loss.

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, 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.

Unlike most cockatoos, Gang-gangs nest in solid trees, into which they excavate a nesting cavity with their powerful bills. Lots of older, dead, 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.
