: ''This article is about hummingbirds from the genus ''Topaza''. For the ruby topaz, see ruby-topaz hummingbird''. The topazes are two species of hummingbirds in the genus ''Topaza''. They are found in humid forests in the Amazon Basin. Males are by far the largest hummingbirds in their range – the giant hummingbird of the Andes is the only larger species in the family. Males have a total length of about , although this includes their elongated rectrices. They are very colourful, being mainly strongly iridescent golden and crimson with a black hood and a green throat. Females lack the elongated rectrices and have a mainly green plumage. ==Species== The lineage commonly referred to as Topazes entails two distinct genera, Topaza and Florisuga which split approximately 18 million years ago. The genus Topaza contains two separate species, the Crimson topaz and the Fiery topaz. It has been suggested that the fiery topaz should be considered a subspecies of the crimson topaz, but today all major authorities consider them as separate species. * Crimson topaz (''Topaza pella'') — (Linnaeus, 1758) * Fiery topaz (''Topaza pyra'') — Gould, 1846 The genus Florisuga encompasses the two species, the White-necked jacobin and the Black jacobin. * White-necked jacobin (''Florisuga mellivora'') * Black jacobin (''Florisuga fusca'') 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「Topaz (hummingbird)」の詳細全文を読む スポンサード リンク
