Green-breasted Mango

Identification

The green-breasted mango is a small hummingbird measuring 10.3 to 12.1 cm long and weighing 5.7 to 7.0 g. Both sexes sport a slightly decurved dull black bill. Adult males of the nominate subspecies display a striking metallic bronze-green crown, nape, and upperparts, with a velvety black stripe running down the chin, throat, and chest bordered by metallic bluish-green. Their tail feathers show purple tones with a metallic gloss on the outer pairs, while their wings are dusky brownish-slate. Females are similar but less bronzy overall, with blue-black outer tail feathers tipped in white and a distinctive white border to their throat stripe. Juveniles resemble females but feature white on the chin, throat, and breast center with some chestnut markings.

Four subspecies exist, each with subtle variations. Subspecies gracilirostris has a shorter, thinner bill and a wider, more bluish-black underside stripe. Hendersoni also features a shorter bill and an ashy-tinged crown. Viridicordatus stands out with bright grass-green upperparts and darker undertail coverts. These distinctions allow experienced birders to identify subspecies in the field.

Range & Habitat

The green-breasted mango ranges from eastern Mexico south through most of Central America, including Colombia and Venezuela. The nominate subspecies occurs from San Luis Potosí and southern Tamaulipas in Mexico through Guatemala, Belize, and El Salvador. Subspecies gracilirostris spans from El Salvador through Honduras, Nicaragua, and Costa Rica into northwestern Panama. The species also occurs on the Caribbean islands of Providencia and San Andrés, and in the coastal regions of Colombia and Venezuela. Vagrants occasionally reach the United States, with at least 25 records in Texas since 1988, and occasional sightings as far north as Wisconsin, North Carolina, Georgia, and Louisiana.

These hummingbirds favor lowland tropical landscapes, typically from sea level to 500 m elevation, though they locally occur as high as 1,100 m in Central America. They inhabit semi-open to open environments including shrublands, savanna, secondary and gallery forests, mangroves, and forest edges. The species readily adapts to cultivated areas, parks, gardens, and suburban and urban settings, making them accessible to nature travelers in populated regions.

Behaviour & Diet

The green-breasted mango forages for nectar and arthropods at all vegetation levels, from understory to canopy. It feeds on nectar from a diverse array of flowering trees, vines, bromeliads, shrubs, and herbaceous plants, and readily visits sugar-water feeders. The species shows no apparent preference for flowers of particular colors, taking nectar while hovering. It supplements its diet by hawking insects and spiders from perches and gleaning prey from vegetation and spider webs.

Breeding seasons vary geographically: March to June on the northern Caribbean slope, October to February in El Salvador, and year-round further south. The female constructs a delicate cup nest from soft plant fibers, tree bark, and lichens, typically bound together with spider silk and sometimes lined with feathers. Nests are usually placed on bare horizontal branches up to 30 m high, though females occasionally use human-made structures like wires, fences, and antennas. Clutches contain two eggs, which the female incubates and broods alone. The species often raises two broods annually. The green-breasted mango is not highly vocal, producing a buzzy, repetitive song and various calls.

Best Time & Places to See It

This species is easiest to observe in open and semi-open habitats where flowering plants are abundant. Gardens, parks, and suburban areas with flowering shrubs and feeders attract them regularly. The northern populations migrate seasonally between September and February, so timing your visit to match local breeding seasons will increase sightings. In the northern Caribbean slope, visit between March and June; in El Salvador, October through February offers the best opportunities. Further south in Central America, the species nests year-round, providing consistent viewing opportunities throughout the year.

Look for this mango in lowland regions from sea level to 500 m elevation, particularly in Mexico, Central America, Colombia, and Venezuela. Sugar-water feeders in gardens and parks are reliable locations, especially in cultivated and urban areas. Early morning visits when flowering plants and insect activity peak will maximize your chances of encountering this jewel.

Photography Tips

Photograph the green-breasted mango at flowers and feeders where you can anticipate their arrival and positioning. The males' metallic bronze-green plumage and striking black-and-green throat patches photograph beautifully with strong directional light that emphasizes their iridescence. Position yourself to capture the distinctive tail patterns, which differ markedly between sexes—males show purple-glossed outer feathers while females display blue-black feathers with white tips.

Since this species forages at all vegetation levels and frequents feeders, you have ample opportunities to compose varied shots. Early morning light will best reveal the metallic colors characteristic of both sexes. The species' relatively small size and rapid movements demand fast shutter speeds and careful focus techniques. Patient observation at flowering plants and feeders will reward you with portraits showcasing this hummingbird's vibrant plumage and acrobatic hovering abilities.
