starts withThe white-browed hermit is 10 cm (4 in) long and weighs 2.5 g (0.09 oz). Sexes are similar, but males have a narrow black breast band and females have longer central tail feathers with paler tips. The facial pattern includes a distinct whitish supercilium and white throat. The bill is black above and yellow below.
The species is difficult to distinguish from the very similar Reddish Hermit (Phaethornis ruber ) which generally occurs at lower elevations, and identification criteria between the two species is still not well known. White-browed Hermit may be slightly paler with more bronze coloration in the tail.
The white-browed hermit's range extends along the base of the Andes from central Peru south to central Bolivia, in an elevational band from 350 m to 1400 m. The species is generally encountered most often within forest interior, although individuals occasionally forage along forest edge.
The white-browed hermit is assumed to be sedentary.
Like most hummingbirds, the white-browed hermit feeds mostly on nectar from a variety of flowers, but also consumes some small arthropods.
The white-browed hermit's breeding phenology has not been documented.
The IUCN has assessed the white-browed hermit as being of Least Concern, though its population size is unknown and believed to be decreasing. It is "ery poorly known, and should probably be classed as Data Deficient".
