starts withThe green-throated mango is 10.5 to 12.5 cm (4.1 to 4.9 in) long. Males weigh 7.5 to 8.5 g (0.26 to 0.30 oz) and females about 6.0 g (0.21 oz). The longish black bill is slightly decurved. The male has glossy bronzy green upperparts. His throat and underparts are green with a black central line on the breast and belly. The central tail feathers are dark brown to green and the others shiny purple, and the outermost have dark blue tips. The female green-throated mango's upperparts are also bronzy green with more of a reddish tinge than the male's. She has white underparts with a black central stripe. The tail is like the male's but with white tips on the outermost feathers. Juveniles resemble females but have chestnut underparts.
This species is very similar to the closely related black-throated mango. Although the male green-throated mango has less extensive black on the underparts, this and other plumage differences are not always easy to confirm in the field because the birds can appear all black. The females of the two species can be almost inseparable, although green-throated has more extensively coppery upperparts than its relative.
The green-throated mango is found coastally from northeastern Venezuela through Guyana, Suriname, and French Guiana into Brazil as far east as Maranhão and along the Amazon River inland to the Negro River. It is also found in Trinidad, but not Tobago. It inhabits mangrove swamp, moist lowland savanna, and similar swampy landscapes with scattered large trees. In elevation it ranges from sea level to 500 m (1,600 ft).

The green-throated mango is sedentary in the coastal part of its range; inland it moves seasonally to follow the flowering of trees.
The green-throated mango feeds on the nectar of tall flowering trees, where males defend feeding territories. The species is also notably insectivorous, catching small arthropod prey on the wing or by gleaning from foliage.
Green-throated mango nests have been found year round, though in the Guianas most have been noted between January and March. Females build a cup nest on an exposed horizontal branch of a large tree, typically at least 10 m (33 ft) above ground. The clutch size is two eggs. The incubation time is 14 to 15 days with fledging usually 24 to 25 days after hatch.
The IUCN has assessed the green-throated mango as being of Least Concern, though its population size is not known and is believed to be decreasing. It is generally locally common in the coastal zone and less so along the Amazon. It is rare in Trinidad due to habitat loss.
