One of the most beautiful of all flowerpiercers, found only at high elevations near tree line in Colombia’s western Andes. Adult is black with a chestnut belly and silvery shoulder patch. Young birds are duller and browner. Also note the oddly shaped bill with a hooked tip, used to penetrate the bases of flowers to extract nectar. Inhabits scrub and stunted forest, and visits hummingbird feeders in at least one location. Song, often quite long, consists of squeaky chirps that constantly change in pitch.
