Observed feeding with Ruby-throated at a feeder, and on coral honey suckle.


Larger than Ruby-throated hummingbirds also using feeder. Long dark wings that flapped at a much slower rate than RTHU. Mostly dark green in color. Deep blue coloring seen in spots on the breast, but they did not form a solid patch. Also deep blue streak seemed to be developing in the face below the eye. Bill was long and slightly curved. Bill and feet all dark black. Undertail coverts were paler than the belly and a dirty white in color. Tail was banded with a pale blue terminal band, then darker band and another pale band near the base. This tail pattern was not distinct but diffuse.


Loud click given singularly, as well in a series that ranged from slow to rapid in delivery.

Similar species:

        Sparkling Violet-eared is larger and the under tail coverts are green as opposed to the dirty white of this bird.

        Buff-bellied have red in the bill and orange in tail as well as no blue in the throat or head.
