Green-breasted mango
The green-breasted mango or Prevost's mango (Anthracothorax prevostii) is a species in subfamily Polytminae of the hummingbird family Trochilidae. It is found from eastern Mexico south through most of Central America, in Colombia and Venezuela, and as a vagrant in the United States.
The green-breasted mango was originally described as Anthracothorax prevostii, was later placed in genera Polytmus and Lampornis, and in 1854 was returned to genus Anthracothorax. As of early 2023, worldwide taxonomic systems assign these four subspecies to it:
A fifth subspecies previous assigned to the green-breasted mango, iridescens, is now a subspecies of the black-throated mango (A. nigricollis).
The specific epithet commemorates the French naturalist Florent Prévost.
The green-breasted mango is 10.3 to 12.1 cm (4.1 to 4.8 in) long and weighs 5.7 to 7.0 g (0.20 to 0.25 oz). Both sexes of all subspecies have a slightly decurved dull black bill. Adult males of the nominate subspecies A. p. prevostii have metallic bronze green crown, nape, and upperparts. Their innermost pair of tail feathers are dull dusky bronze green to dull coppery bronze, and the outer four pairs are shades of purple with a metallic gloss. Their wings are dusky brownish slate. They have a velvety black stripe down their chin, throat, and chest with metallic bluish green beside it. Their sides and flanks are bronze green and their undertail coverts are dusky purple. Nominate females have less bronzy metallic green on the crown, nape, and upperparts than males. Their innermost pair of tail feathers are dull dusky bronze green to dull coppery bronze like the male's, but the outer four pairs are blue-black with a wide purple base and whitish tips. 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.
Subspecies A. p. gracilirostris has a shorter and thinner bill than the nominate. Its upperparts and sides are less bronzy, its underside stripe is wider and bluish black, and its undertail coverts are darker. A. p. hendersoni also has a shorter bill than the nominate. It has an ashy tinge on the crown and a longer and thinner bluish black stripe. A. p. viridicordatus has bright grass green upperparts, olive green central tail feathers, and darker undertail coverts than the nominate.
The subspecies of green-breasted mango are found thus:
Many individuals of the nominate subspecies have wandered to the United States. Since 1988 there have been at least 25 records in Texas. Single birds have strayed to Cabarrus County, North Carolina in 2000; Rock County, Wisconsin in 2007, Laurens County, Georgia in 2007 into 2008; and Caddo Parish, Louisiana in 2009.
