''Spinus'' is a genus of passerine birds in the finch family. It contains the North and South American siskins and goldfinches. All of the species in the genus other than the Tibetan serin were formerly included in the genus ''Carduelis''. They were moved to the resurrected genus ''Spinus'' based on phylogenetic studies of mitochondrial and nuclear DNA sequences. The Tibetan serin was formerly placed in the genus ''Serinus''. The Eurasian siskin and the Tibetan serin are the only species from the Old World included in the group.〔 The name ''Spinus'' was introduced in 1816 by the German naturalist Carl Ludwig Koch. ==Species== The genus contains 20 species:〔 * Tibetan serin, ''Spinus thibetanus'' * American goldfinch, ''Spinus tristis'' * Lawrence's goldfinch, ''Spinus lawrencei'' * Lesser goldfinch, ''Spinus psaltria'' * Eurasian siskin, ''Spinus spinus'' * Antillean siskin, ''Spinus dominicensis'' * Pine siskin, ''Spinus pinus'' * Black-capped siskin, ''Spinus atriceps'' * Black-headed siskin, ''Spinus notata'' * Black-chinned siskin, ''Spinus barbata'' * Yellow-bellied siskin, ''Spinus xanthogastra'' * Olivaceous siskin, ''Spinus olivacea'' * Hooded siskin, ''Spinus magellanica'' * Saffron siskin, ''Spinus siemiradzkii'' * Yellow-faced siskin, ''Spinus yarrellii'' * Red siskin, ''Spinus cucullata'' * Black siskin, ''Spinus atrata'' * Yellow-rumped siskin, ''Spinus uropygialis'' * Thick-billed siskin, ''Spinus crassirostris'' * Andean siskin, ''Spinus spinescens'' ==References== 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「Spinus (genus)」の詳細全文を読む スポンサード リンク
