The booted racket-tails are a small group of hummingbirds in the genus Ocreatus that was long considered to have only one species, O. underwoodii. They are native to cloud forests in the South American Andes and Maritime Andes. They are relatively small, mostly green hummingbirds with white or rufous leg-puffs ("boots") and males' have two long racket-shaped extensions to the tail.
Taxonomy
The genus was first recognized by John Gould in 1846. Field research by Karl-L. Schuchmann published in 2016, however, found notable differences between some populations traditionally assigned to O. underwoodii, and recommended that three allopatric subspecies groups, addae, annae and peruanus, should be raised to species level.[2] The research results have been mostly accepted by the International Ornithological Union, with more data required for the species status of Anna's racket-tail (annae), which they instead regard as a subspecies of O. addae.[3] The American Ornithological Society has yet to recognize the split.
Species
The genus contains three species:[4]
| Male | Female | Common name | Name | Distribution |
