The palm cockatoo (''Probosciger aterrimus''), also known as the goliath cockatoo or great black cockatoo, is a large smoky-grey or black parrot of the cockatoo family native to New Guinea and far north Queensland, Australia. It has a very large black beak and prominent red cheek patches. The bird was also called Goliath Aratoo in Wood's Natural History (1862). ==Taxonomy== The palm cockatoo was originally described by German naturalist Gmelin in 1788. Its specific name, ''Probosciger aterrimus'', is from Latin ''proboscis'', long thin nose + ''-ger'', carry and Latin superlative adjective for ''ater'', black, hence a "black () with a long thin nose (beak)". It is the only member of the subfamily Microglossinae and the only member of the monotypic genus, ''Probosciger''. Its unique position within the cockatoo family has been confirmed by molecular studies. It is the earliest offshoot from the ancestors of what have become the cockatoo family. There are three poorly differentiated subspecies, and one distinctive subspecies: Cape York cockatoo (''P. a. aterrimus''(1788 )), the larger goliath cockatoo (''P. a. goliath''(1820 )), Northern palm cockatoo (''P. a. stenolophus''(Ort 1911 )) similar to goliath but crest feathers much narrower, and ''P. a. macgillivrayi''(1927 ) intermediate in size. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「palm cockatoo」の詳細全文を読む スポンサード リンク
