The bearded mountaineer (Oreonympha nobilis) is a species of hummingbird in the family Trochilidae.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 Henry Whitely at Tinta District, and placed it in its own genus Oreonympha. He recognised a kinship with Oxypogon and Ramphomicron. 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 nobi
