Chlorostilbon is a genus of hummingbird in the Trochilidae family, known as Emeralds (as are some hummingbirds in the genera Amazilia and Elvira). A single species, the Blue-chinned Sapphire is variously placed in the monotypic genus Chlorestes or in Chlorostilbon, with the latter treatment used in the list below. The taxonomy of the C. mellisugus superspecies is highly complex and, depending on view, includes 1-8 species. All species in this genus have straight black or black-and-red bills. The males are overall iridescent green, golden-green or bluish-green, and in some species the tail and/or throat is blue. The females have whitish-grey underparts, tail-corners and post-ocular streak (with the exception of the female Blue-chinned Sapphire which lacks the post-ocular streak).
