Green Throated Mango Hummingbird. (Anthracothorax viridigula)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 appear all-black. The females of the two species can be almost inseparable, although Green-throated has more extensively coppery upperparts than its relative.
