The bearded mountaineer (''Oreonympha nobilis'') is a species of hummingbird in the Trochilidae family. It is found only in Peru. Its natural habitat is subtropical or tropical high-altitude shrubland. The ornithologist John Gould described the species in 1869, from a specimen collected by H. Whitely at Tinta District, and placed it in its own genus ''Oreonympha''. He recognised a kinship with ''Oxypogon'' and ''Ramphomicron''. The genus name is derived from the Ancient Greek words ''oreo-'' "mountain" and "nympha" "nymph", while the specific epithet is the Latin adjective ''nobilis'', "noble". A study of mitochondrial DNA of hummingbirds shows it to be most closely related to the bearded helmetcrest (''Oxypogon guerinii'') and the rufous-capped thornbill (''Chalcostigma ruficeps''). The other member of the genus ''Chalcostigma'' lay outside the group, suggesting the genus might need revising in the future. Two subspecies are recognised - the more widespread nominate subspecies ''nobilis'' has a blue eyebrow, while the more restricted ''albolimbata'' has white. Measuring in length, it is a large hummingbird with a long tail and a long bill. The underparts of both sexes are white, while the tail is white underneath with black feather tips. The male has a green and purple throat.〔 The upper parts are a bronze-sheened brown and the legs and bill are black.〔 The species is endemic to Peru, where it is found in high altitude valleys in the south-central Andes, from . It lives in scrubland, and often visits tobacco (''Nicotiana'') plants along roadsides.〔 ==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「Bearded mountaineer」の詳細全文を読む スポンサード リンク
