It is found from eastern Mexico south through most of Central America, in Colombia and Venezuela, and as a vagrant in the United States.

Adult males of the nominate subspecies A. p. prevostii have metallic bronze green crown, nape, and upperparts.

They have the same velvety black chin and throat stripe as males but it becomes bluish green on the breast, dusky on the belly, and has a white border.

The rest of their underparts are metallic green but for dusky undertail coverts with wide white edges.

Juveniles are similar to adult females but have a white chin, throat, and center of the breast with some chestnut beside it.

Its upperparts and sides are less bronzy, its underside stripe is wider and bluish black, and its undertail coverts are darker.

[10][6] The green-breasted mango inhabits a variety of landscapes in the lowland tropics, most of them semi-open to open.

[6] The population of the green-breasted mango that breeds from Oaxaca north withdraws from there between September and February, generally to the Pacific slope from southern Mexico to El Salvador.

Its nectar sources have not been detailed but include a wide variety of flowering trees, vines, bromeliads, shrubs, and herbaceous plants; it also frequents sugar water feeders.

The female builds a cup nest of soft plant fibers with tree bark and lichens on the outside and sometimes small feathers as a lining; all is held together with spider silk.

It has a very large range and an estimated population of at least a half million mature individuals, though the latter is believed to be decreasing.
