Peruvian piedtail

The Peruvian piedtail (Phlogophilus harterti), locally called Colibrí Colipinto Peruano, is a species of hummingbird in the "coquettes", tribe Lesbiini of subfamily Lesbiinae. It is endemic to Peru.

Taxonomy and systematics
The Peruvian piedtail shares its genus with the Ecuadorian piedtail (P. hemileucurus). It is monotypic.

Description
The Peruvian piedtail is 7.2 to 7.5 cm long and weighs 2.2 to 2.7 g. The adult male and female are alike. They have a short, straight, black bill. Their upperparts are green. They have a white spot behind the eye. The throat and center of the breast and belly are white and the rest of the underparts buff. The innermost pair of tail feathers are green with a wide black tip; the others are buff with a wide diagonal black band. Juveniles resemble the adults but their head and neck feathers have buff fringes.

Distribution and habitat
The Peruvian piedtail has a discontinuous distribution in central and southeastern Peru. It occurs in the east Andean foothills of Huánuco, Pasco, Cuzco, and Puno departments. It inhabits the interior of primary and secondary forest. In elevation it is most numerous around 1000 m but ranges between 750 and 1500 m.

Movement
The Peruvian piedtail is mostly sedentary but some altitudinal movements are believed to be likely.

Feeding
The Peruvian piedtail perches to take nectar from flowers and to glean small insects from foliage.

Breeding
Nothing is known about the Peruvian piedtail's breeding phenology.

Vocalization
The Peruvian piedtail's song is "a shrill, thin series of notes, which descend sequentially in pitch, 'SIIII siii suuu'."

Status
The IUCN has assessed the Peruvian piedtail as least concern. Though its habitat is generally intact, logging and conversion to agriculture are threats. It "accepts modification of habitat by man, as long as patches of forest and secondary growth remain."
