The small ground finch (''Geospiza fuliginosa'') is a species of bird in the tanager family Thraupidae. Endemic to the Galápagos Islands, it is common and widespread in shrubland, woodland, and other habitats on most islands in the archipelago. It commonly feeds on small seeds and parasites from the skins of Galápagos tortoises, and Galápagos land and marine iguanas. ==Taxonomy and systematics== The small ground finch is one of Darwin's finches, a group of closely related birds which evolved on the Galápagos Islands. The group is related to the ''Tiaris'' grassquits, which are found in South America and the Caribbean.〔 When Charles Darwin first collected the species in 1835, he thought it was a finch. John Gould, who officially described Darwin's specimens, agreed, placing it in the genus ''Fringilla'' with the Old World finches. By 1841, Gould had changed his mind, moving this and five other species into the new genus ''Geospiza'' — still a genus of finches, but distinct from those of the Old World.〔 DNA research has now shown that all Darwin's "finches" are actually tanagers.〔 The name ''Geospiza'' is a combination of the Greek words ''geo''-, meaning "ground-", and ''spiza'', meaning finch.〔 The specific name ''fuliginosa'' is late Latin for "sooty".〔 It is known to hybridize (rarely) with the medium ground finch.〔 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「Small ground finch」の詳細全文を読む スポンサード リンク
