These high-flying hummers are rather insectivorous and catch bugs by hovering in the air. They also form feeding territories in the tops of flowering trees. The Green-throated Mango prefers coastal areas including mangroves, swamp forests, and semi-wooded zones. Unfortunately, the Trinidad population is now rare because of the loss of mangrove and swamp habitat. The male’s entirely green throat distinguishes it from others in the genus, and the female displays a slight reddish tinge on the upperparts. Their cup nests are exposed on a horizontal branch and are caked with lichen, at least in Suriname.
