The Corsican finch (''Carduelis corsicana''), also known as Corsican citril finch or Mediterranean citril finch is a bird in the finch family, Fringillidae. It was formerly regarded a subspecies of the citril finch, but it differs in morphology and vocalizations (Cramp & Perrins, 1994, Förschler & Kalko, 2007) as well as mtDNA sequence (Sangster, 2000, ''contra'' Pasquet & Thibault, 1997, Förschler ''et al.'' 2009) and they are now considered distinct species (Sangster ''et al.'', 2002, Förschler ''et al.'' 2009). Formerly, both were placed in the genus ''Serinus'', but they appear to be close relatives of the European goldfinch (Arnaiz-Villena ''et al.'', 1998, ''contra'' van den Elzen & Khoury, 1999). It is found in Corsica, Sardinia and on the Italian islands of Elba, Capraia and Gorgona. It has dark-streaked brown upperparts, and brighter yellow underparts than the citril finch. ==Phylogeny== It has been obtained by Antonio Arnaiz-Villena et al. 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「Corsican finch」の詳細全文を読む スポンサード リンク
