The white-vented plumeleteer (Chalybura buffonii) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Colombia, Ecuador, Panama, Peru, and Venezuela.
Taxonomy and systematics
Most taxonomic systems assign five subspecies to the white-vented plumeleteer:
C. b. micans Bangs & Barbour, 1922
C. b. buffonii Lesson, RP, (1832)
C. b. aeneicauda Lawrence, 1865
C. b. caeruleogaster Gould, (1847)
C. b. intermedia Hartert, EJO & Hartert, CBE, 1894
However, BirdLife International's Handbook of the Birds of the World (HBW) assigns C. b. intermedia as a subspecies of bronze-tailed plumeleteer (C. urochrysia).
Both C. b. caeruleogaster and C. b. intermedia have at times been proposed as separate species.
