Blue-throated Sapphire

Identification

The Blue-throated Sapphire is a small hummingbird measuring 9 cm (3.5 inches) and weighing just 3.6 grams. Males are slightly larger than females and display more vibrant plumage. The most distinctive feature is the male's glittering blue-violet to violet throat, which contrasts sharply with its green crown and upperparts and cream-brown buff belly. The tail shades to a metallic golden-green, and the sides of the breast and flanks are streaked with green. Both sexes have a striking straight bill that is bright red with a black tip. Females are considerably paler overall, with a violet-blue throat mixed with gray buff and more black on the bill. Juveniles resemble females with duller colors, particularly noticeable in young females.

This species can be confused with the Rufous-tailed Hummingbird, which is larger with a longer rufous tail, green throat and breast, and a more curved bill. The Blue-headed Sapphire also resembles this species but differs by its blue crown, sides of the head, green throat, and blue tail. Where their ranges overlap in extreme eastern Panama and northwestern Colombia, the two species show no evidence of interbreeding.

Range & Habitat

The Blue-throated Sapphire is found from southern Mexico through Central America to western Panama, with a few occurrences in northern Chocó, Colombia. It occurs throughout Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. The species is resident throughout most of its range, with seasonal movements that remain poorly documented.

This hummingbird occupies subtropical and tropical moist lowland forests and heavily degraded former forest areas. It typically inhabits lowlands and valleys, usually between 950 and 1000 meters elevation, though specimens have been recorded up to 2000 meters in places such as Braulio National Park in Costa Rica and in El Salvador.

Behaviour & Diet

Like all hummingbirds, the Blue-throated Sapphire is primarily nectarivorous, feeding on flowers of shrubs such as Stachytarpheta and Hamelia, as well as large herbs including Heliconia, Renealmia, and Thalea. It also feeds on epiphytes and occasionally supplements its diet with small arthropods.

Males are highly vocal and sing in leks with a distinctive song that varies between different leks and sometimes within a single lek. The typical song consists of 5-8 notes, beginning with a piercing "tseee" followed by single, double notes, or short trills, with males usually giving 1-3 phrases before pausing and repeating. The species produces high, buzzy "tzip" or "tzet" calls, with aggressive interactions accompanied by sharp, liquid, descending twitter sounds.

Best Time & Places to See It

The Blue-throated Sapphire is resident year-round throughout most of its range, making it a reliable species for wildlife travelers. The species is relatively common in suitable habitat across Central America, from Mexico through Panama. Look for this hummingbird in subtropical and tropical moist lowland forests and in areas of disturbed or degraded former forest, where flowering shrubs and herbs provide abundant nectar sources.

Photography Tips

Photographing this small hummingbird requires patience and careful attention to lighting. The male's glittering blue-violet throat is the defining field mark, but this iridescent coloration is highly directional and will only show brilliantly when the bird is positioned to catch the light at the correct angle. Position yourself with the sun behind you or to the side to maximize the throat's iridescence. Males singing in leks offer excellent opportunities to observe and photograph perched birds, though they may be territorial and vocal rather than hovering at flowers. Fast shutter speeds are essential to freeze wing motion, and a telephoto lens will help you maintain distance and minimize disturbance to this small bird.
