The eastern rosella (''Platycercus eximius'') is a rosella native to southeast of the Australian continent and to Tasmania. It has been introduced to New Zealand where feral populations are found in the North Island 〔Falla RA, Sibson RB & Turbot EG (1966) ''A Field guide to the birds of New Zealand''. Collins, London (ISBN 0-00-212022-4)〕 (notably in the northern half of the island and in the Hutt Valley) and in the hills around Dunedin in the South Island.〔(【引用サイトリンク】title=3. Cockatoos and rosellas – Introduced land birds – Te Ara Encyclopedia of New Zealand )〕〔(''Notornis'' (Ornithological Society of New Zealand journal), 2002 )〕 ==Taxonomy== The eastern rosella was named by George Shaw in 1792. It is sometimes considered a subspecies of the pale-headed rosella (''P. adscitus''). The term 'white-cheeked rosella' has been used for a species or superspecies combining the pale-headed and eastern forms. Hybrids of the two taxa have been recorded where their ranges meet in northeastern New South Wales and southeastern Queensland. Three subspecies of eastern rosella are recognised: * ''P. e. eximius'', Victoria and southern New South Wales. Black feathers on the back have green margins. Rump is pale green. * ''P. e. elecica'', northeast New South Wales and southeast Queensland. In the male the black feathers on the back have golden-yellow margins, and greenish-yellow in the female. The rump is bluish-green. This subspecies is also called the golden-mantled rosella, often abbreviated to GMR. * ''P. e. diemenensis'', eastern Tasmania. White cheek patches are larger and the red on the head is darker. 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「Eastern rosella」の詳細全文を読む スポンサード リンク
