Fantastic cloud forest hummingbird found in the eastern Andes from southern Colombia to central Peru. Male has a straight tail ending in rackets and buffy leg puffs. On female, note the combination of short bill, white underparts scaled with green, white facial marks, and buffy thighs. She is quite similar to female Rufous-vented Whitetip, but has buff (not white) thighs and fewer markings on throat. May overlap with Rufous-booted Racket-tail at the southern edge of its range; male Peruvian Racket-tail has straight central tail feathers that do not cross; females of the two species look almost identical. Typically feeds at small flowers at forest edge or in clearings, and sometimes visits feeders.
