Males have a medium length slightly decurved bill; the female's is longer and more strongly curved.Farnsworth, A. (2020). Green-throated Carib (''Eulampis holosericeus''), version 1.0.

Behavior

Feeding

The green-throated carib feeds on the nectar of a variety of flowering shrubs and trees. Males are believed to defend flowering feeding territories all year but females do so only in the non-breeding season. The species also feeds on small

s such as insects and spiders, mostly caught on the wing.

Breeding

The green-throated carib is believed to nest between March and July, and might depend on the timing of rain. Its nest is a cup lined with soft fibers and has lichen and bark chips attached to the outside. It is usually placed in the fork of a branch above the ground. The clutch is two eggs. The incubation time is 17 to 19 days with

has assessed the green-throated carib as being of Least Concern, though its population size and trend are not known. It has a restricted range but is described as common in much of it. The species "adapts well to human-affected habitats such as second growth gardens and vegetation around homes" but because its movement patterns are not fully understood, habitat fragmentation might be a threat.
