Psittirostrini is one of three tribes belonging to the Hawaiian honeycreepers. It is made up of the thick-billed birds, colloquially known as the Hawaiian finches, that once inhabited all of the Hawaiian Islands. These birds are granivorous and have songs like those of cardueline finches. Extant species include the Laysan finch, the Nihoa finch, the Maui parrotbill, and the palila, which may possibly be the last remaining species left alive in this group. Extinct species include the four koa finches, the ʻōʻū, and the Lānai hookbill. ==Genera and species== * * Genus ''Chloridops'' Wilson, 1888 - thick-billed, ''Myoporum sandwicense'' and other hard seed specialists * * * ''Chloridops kona'' Wilson, 1888 - Kona grosbeak (extinct, 1894) * * * ''Chloridops regiskongi'' - King Kong grosbeak (prehistoric) * * * ''Chloridops wahi'' - Wahi grosbeak (prehistoric) * * Genus ''Dysmorodrepanis'' Perkins, 1919 - pincer-like bill, possibly snail specialist * * * ''Dysmorodrepanis munroi'' Perkins, 1919 - Lānai hookbill (extinct, 1918) * * Genus ''Loxioides'' Oustalet, 1877 - finch-like, Fabales seed specialists * * * ''Loxioides bailleui'' Oustalet, 1877 - palila * * * ''Loxioides kikuichi'' Olson & James, 2006 - Kauai palila (prehistoric, possibly survived to the early 18th century) * * Genus ''Orthiospiza'' - large weak bill, possibly soft seed or fruit specialist * * * ''Orthiospiza howarthi'' James & Olson, 1991 - highland finch (prehistoric) * * Genus ''Pseudonestor'' - parrot-like bill, probes decomposing wood for insect larvae * * * ''Pseudonestor xanthophrys'' Rothschild, 1893 - Maui parrotbill (thought to be extinct, rediscovered in 1945) * * Genus ''Psittirostra'' - slightly hooked bill, ''Freycinetia arborea'' fruit specialist * * * ''Psittirostra psittacea'' Gmelin, 1789 - ōū (probably extinct, 1998?) * * Genus ''Rhodacanthis'' - large-billed legume specialists * * * ''Rhodacanthis flaviceps'' Rothschild, 1892 - lesser koa-finch (extinct, 1891) * * * ''Rhodacanthis forfex'' James & Olson, 2005 - scissor-billed koa-finch (prehistoric) * * * ''Rhodacanthis litotes'' James & Olson, 2005 - primitive koa-finch (prehistoric) * * * ''Rhodacanthis palmeri'' Rothschild, 1892 - greater koa-finch (extinct, 1896) * * Genus ''Telespiza'' Wilson, 1890 - finch-like, granivores, opportunistic scavengers * * * ''Telespiza cantans'' Wilson, 1890 - Laysan finch * * * ''Telespiza persecutrix'' James & Olson, 1991 - Kauai finch (prehistoric) * * * ''Telespiza ultima'' Bryan, 1917 - Nihoa finch * * * ''Telespiza ypsilon'' James & Olson, 1991 - Maui Nui finch (prehistoric) * * Genus ''Xestospiza'' James & Oslon, 1991 - cone-shaped bills, possibly insectivores * * * ''Xestospiza conica'' James & Olson, 1991 - cone-billed finch (prehistoric) * * * ''Xestospiza fastigialis'' James & Olson, 1991 - ridge-billed finch (prehistoric) 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「Psittirostrini」の詳細全文を読む スポンサード リンク
