is glittering turquoise green. The adult female is overall dark smoky gray with a smaller gorget than the male. Juveniles are similar to the female but without a gorget.

Distribution and habitat

The black metaltail is found on the western slope of the Peruvian Andes from southern

Behavior

Movement

The black metaltail is believed to be sedentary but some seasonal elevational movement is possible.

Feeding

The black metaltail feeds on nectar from a wide variety of low flowers and flowering bushes, shrubs, and trees. It also eats small insects. It usually takes nectar while hovering but will also cling to flowers and sometimes "rob" nectar by piercing the base of a flower. Males defend feeding territories.

Breeding

The black metaltail's egg-laying season is thought to span from July to January. Three nests have been described; they were cups made of moss and lined with feathers. One was on a steep mossy bank and the other two were built into the bases of unused nests of other bird species, perhaps a canastero of genus '' Asthenes''. The female alone incubates the clutch of two eggs. The incubation period and time to fledging are not known.

Vocalization

What is thought to be the black metaltail's song is "a repeated high-pitched single note, ''tsee.....tsee.....tsee...''". Its presumed chase call is "a descending series of 4–6 high-pitched notes reminiscent of a ''Picumnus'' piculet". It also makes a repeated "short dry trill; ''djrrt''...and longer dry chatters."

Status

has assessed the black metaltail as being of Least Concern. Its population size is not known and is believed to be decreasing. It is fairly common in many areas and is found in some protected areas. However, its habitat is under significant human pressure.
