[6] The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.

[7] Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Trochilus viridigula in his catalogue of the Planches Enluminées.

It inhabits mangrove swamp, moist lowland savanna, and similar swampy landscapes with scattered large trees.

[11] The green-throated mango is sedentary in the coastal part of its range; inland it moves seasonally to follow the flowering of trees.

The species is also notably insectivorous, catching small arthropod prey on the wing or by gleaning from foliage.

[11] 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.

[11][13] 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.
