Bronze-tailed Plumeleteer
Chalybura urochrysia
The bronze-tailed plumeleteer is 10.5 to 12 cm (4.1 to 4.7 in) long. Males weigh about 7.1 g (0.25 oz) and females about 6.1 g (0.22 oz). Both sexes of all subspecies have a black maxilla and tip of the mandible; the rest of the mandible is dull pink to dark red. Males of the nominate subspecies have metallic green upperparts and glittering green underparts, with long fluffy white undertail coverts. Their tails are bronze-green. Females are also metallic green above but gray below with green flecks on the side. Voice: What is thought to be the bronze-tailed plumeleteer's song is "a soft, nasal, scratchy, trilled phrase, ter-twee-ee-ee-ee-ee....ter-twee-ee-ee...". It makes "a drawn-out descending chattering trill" when chasing and also "loud chup and chip notes".

White-vented Plumeleteer
Chalybura buffonii
The white-vented plumeleteer is 10.5 to 12 cm (4.1 to 4.7 in) long. Males weigh 6 to 7.3 g (0.21 to 0.26 oz) and females 5.9 to 7.9 g (0.21 to 0.28 oz). All of the subspecies except intermedia have a black bill and black feet; that one has a pinkish base to the mandible and pale pink to red feet. Males of the nominate subspecies C. b. buffonii have mostly dark metallic green upperparts with a bronzy tinge to the crown and coppery bronze uppertail coverts. Their upper breast is bluish, lower breast bright metallic green, the lower belly whitish, and the undertail coverts long and white. Voice: The white-vented plumeleteer's song has not been described in words, but it is known to make "chip" notes while foraging.
