The Purple-throated Carib (Eulampis jugularis) is a species of hummingbird in the family Trochilidae. This bird is unmistakable in most situations, though a silhouetted bird could be mistaken for the similarly-shaped Green-throated Carib (Eulampis holosericeus).
The Purple-throated Carib shows black plumage with a royal purple throat and upper chest and green wing coverts, blue under-tail coverts, and a medium-length de-curved bill, which it uses to feed on Heliconia flowers. In plumage, the Purple-throated Carib is monomorphic, but the male is slightly larger, and more aggressive, maintaining smaller territories within areas of high flower density, relative to the large, low-density territories of the females.

The Purple-throated Carib can be found in Antigua, Dominica, Guadeloupe, Martinique, Montserrat, Saint Kitts and Nevis, Saint Lucia, and Saint Vincent. It has occurred as a vagrant in Barbados, Barbuda, Grenada and the Virgin Islands.
