Description

It is 10.2 cm long and weighs 7.2g. The longish black bill is slightly decurved. The tail in both sexes has dark central feathers, the outer tail being wine-red tipped with black.

The male has glossy bright green upperparts. His throat and chest are matt black, bordered with blue-green. The flanks are bright green, and the black of the chest tapers onto the belly.

The female Black-throated Mango has bronze-green upperparts and white underparts with a black central stripe. Immature birds show some grey or buff feather tips on the head and wings, and have brown around the eyes.

The call of the Black-throated Mango is a high-pitched tsiuck, and the song is a buzzing hsl-hsl-hsl-hsl-hsl-hsl-hsl.

This species is very similar to the closely related Green-breasted Mango

. Although the male Black-throated Mango has more extensive black on the underparts, this and other plumage differences are not always easy to confirm in the field because the birds appear all-black. The females of the two species can be almost inseparable, although the Black-throated lacks the more extensively coppery upperpart of its relative.
