The Green-breasted Mango, known scientifically as Anthracothorax prevostii, is a hummingbird of striking poise. This species, with its iridescent plumage, measures between 10.3 to 12.1 cm in length and tips the scales at a delicate 5.7 to 7.0 grams.
Adult males of the Green-breasted Mango boast a metallic bronze-green crown and upperparts, with a velvety black stripe running down their chin and chest, flanked by metallic bluish-green. Their tail feathers shimmer with purple hues. Females, while similar, have less metallic green and their tail feathers are blue-black with a purple base and white tips. Both sexes have a slightly decurved dull black bill.
This species thrives in a variety of lowland tropical landscapes, from semi-open to open environments. These include shrublands, savannas, secondary forests, and mangroves, as well as human-altered areas such as parks and gardens.
The Green-breasted Mango is found from eastern Mexico through Central America, and into Colombia and Venezuela. It has also been recorded as a vagrant in the United States.
