Brace's emerald (Riccordia bracei) is an extinct species of hummingbird which was endemic to the main island of the Bahamas, New Providence.

The crissum (the undertail covert which surrounded the cloacal opening) was white with a faint yellow hue at the edges.

In 1982, palaeornithologists William Hilgartner and Storrs Olson discovered fossil remains of three hummingbird species from the Pleistocene in the deposits in a cave of New Providence.

[citation needed] These were the Bahama woodstar (Nesophlox evelynae), Cuban emerald (R. ricordii; also R. elegans), and another species, which was later identified as Riccordia bracei.

It formed a relict population, and most likely due to habitat loss and human disturbance (e.g. agriculture), it became extinct at the end of the 19th century.
