Violet Sabrewing

Identification

The violet sabrewing is the largest hummingbird found in Mexico and Central America, measuring 13 to 15 cm in length and weighing 9 to 12 grams. Males of the nominate subspecies are strikingly coloured, with a dusky crown showing a bluish-green gloss and brilliant metallic violet-blue plumage on the nape, upper back, face, and underparts—the belly tinged slightly more blue. Their lower back and uppertail coverts are metallic green, while the central tail feathers are bluish-green to bluish-black; the remaining tail feathers are blackish with distinctive wide white tips. Females are more subdued, sporting a dusky crown and metallic green to bronze-green upperparts with a bluish-green rump and a violet-blue throat. Their underparts are mostly gray with a whiter belly and metallic green spots along the sides. Both sexes have a black bill, though birds of the subspecies C. h. mellitus have notably longer bills. Males of the mellitus subspecies show more green on their upper parts and almost entirely violet underparts, while females of this race have coppery-tinged upperparts.

Range & Habitat

The violet sabrewing is found from Mexico to Panama, with two subspecies occupying different ranges. The nominate subspecies inhabits the Mexican states of Guerrero and Veracruz, ranging intermittently southward through Guatemala, southern Belize, Honduras, and El Salvador into northern Nicaragua. The mellitus subspecies occurs across most of Costa Rica and into western Panama. The species prefers humid evergreen montane forests, inhabiting both forest edges and interior locations, as well as mature secondary forest, banana plantations, and gardens. Elevational preferences vary by region: in Mexico, violet sabrewings generally occur between 500 and 2,000 metres, occasionally reaching 2,500 metres, while in Costa Rica they range between 1,500 and 2,400 metres.

Behaviour & Diet

Violet sabrewings are largely sedentary, though individuals frequently descend to lower elevations after breeding season. They feed primarily by trap-lining, visiting a circuit of flowering plants in search of nectar. Males are notably aggressive, often defending patches of flowers and dominating other hummingbird species at feeding sites. The birds forage mostly in the understory, favouring Heliconia, banana, Cephalism, and Palic urea flowers, and readily visit nectar feeders. Beyond nectar, they supplement their diet with small arthropods gleaned from foliage and spiderwebs. During breeding season—June to September in Mexico and May to November in Costa Rica—males court females through singing in leks situated in the understory or at forest edges. Females construct tiny cup nests of moss cemented with spider silk and lined with fine fibres, typically placing them 1 to 6 metres above ground on horizontal branches over ravines or streams. A clutch of two eggs is incubated for 19 to 22 days, with fledging occurring 22 to 24 days after hatching. In Costa Rica, pairs may raise two broods per season. The species produces loud, high-pitched vocalizations described as piercing and ventriloquial, with varied sharp chipping, warbles, and explosive notes.

Best Time & Places to See It

Birdwatchers and nature travellers can encounter violet sabrewings throughout their range in montane forest habitats, with the best opportunities during breeding season when birds are most active and vocal. In Mexico, visit between June and September; in Costa Rica, the May to November breeding season offers extended viewing opportunities. Look for them in humid evergreen montane forests at appropriate elevations, particularly at forest edges and in the understory. Gardens and banana plantations also attract the species. The birds are relatively common within their range and readily visit nectar feeders, making them accessible to visitors staying in mountain lodges and reserves.

Photography Tips

Photograph violet sabrewings at nectar feeders for reliable close encounters, positioning yourself downwind to avoid disturbing the birds. The males' brilliant violet-blue plumage requires careful exposure management to capture detail without blown highlights; shoot in open shade when possible to reduce contrast. Capture their aggressive territorial behaviour by photographing multiple birds at feeders, or position yourself near flowering plants in the understory where they naturally forage. Early morning and late afternoon light brings out the iridescent qualities of their plumage. The species' large size relative to other hummingbirds makes them excellent subjects for detailed head and tail studies.
