The violet sabrewing (Campylopterus hemileucurus) is a species of hummingbird in the "emeralds", tribe Trochilini of the subfamily Trochilinae.

Their central tail feathers are bluish green and the rest blacker with wide white tips.

[5][6] Males of subspecies C. h. mellitus have more green on their upper parts than the nominate and almost entirely violet underparts with no blue on the belly.

[5] The nominate subspecies of violet sabrewing is found from the Mexican states of Guerrero and Veracruz intermittently south through Guatemala, southern Belize, Honduras, and El Salvador into northern Nicaragua.

[5][7] The violet sabrewing is mostly sedentary, but individuals frequently move to lower elevations after the breeding season.

[5] The violet sabrewing feeds on nectar primarily by trap-lining, visiting a circuit of flowering plants.

[5][7] The violet sabrewing breeds during the local rainy season, which ranges from June to September in Mexico and May to November in Costa Rica.

[1] "This species can tolerate habitat disturbance, however, as long as some forest cover or tall second growth persists.
