White-bearded hermit

The white-bearded hermit (Phaethornis hispidus) is a species of hummingbird in the family Trochilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela.

Taxonomy and systematics
The white-bearded hermit is monotypic.

Description
The white-bearded hermit is about 13 to 14 cm long and weighs 4 to 6 g. This medium-sized hermit has bronzy green upperparts with gray margins on the uppertail coverts. The underparts are gray. The face has a black "mask" with a white supercilium and malar stripe; the center of the throat has a white stripe. The female has identical plumage but shorter wings and a shorter and more decurved bill than the male.

Distribution and habitat
The white-bearded hermit is found in Amazonia, from the Andean foothills of western and southern Venezuela south through eastern Colombia, Ecuador, and Peru to northeastern Bolivia, and east throughout western Amazonian Brazil. In elevation it usually ranges as high as 850 m but has been recorded up to 1200 m in Peru. It is a bird of humid landscapes. In the lowlands it mostly inhabits regularly inundated areas, such as along rivers and in várzea forest. At higher elevations if favors gallery forest in the cerrado and llanos.

Movement
No information about the white-bearded hermit's movements has been published.

Feeding
The white-bearded hermit is a "trap-line" feeder like other hermit hummingbirds, visiting a circuit of a wide variety of flowering plants for nectar. It also consumes small arthropods.

Breeding
The breeding seasons of the white-bearded hermit vary throughout its large range but have not been defined in detail. Like many hermits, it builds a cone-shaped nest suspended from the underside of drooping leaf. The clutch size is two eggs.

Vocalization
The white-bearded hermit's song is "a continuous series of high-pitched single notes 'seep'. It is typically sung from a low perch while gathered at a lek with other males. Its call is "a short explosive 'pip!'."

Status
The IUCN has assessed the white-bearded hermit as being of Least Concern though its population size is unknown and believed to be decreasing. It occurs in several protected areas and its "[w]ide distribution and adaptability probably mean that species is not threatened."
