The female is metallic green above, dingy white below, and has a relatively long, forked tail. The Antillean Mango is shorter tailed (wings just about even with tail tip when perched) and has a distinctly down-curved bill. The Vervain Hummingbird is much smaller and shorter billed than the Hispaniolan Emerald. Most common vocalization is a sharp “tic,” most often given in a prolonged series at about five “tics” per second.
