Subspecies
Forms a superspecies with Buff-bellied Hummingbird (Amazilia yucatanensis), but not, as sometimes suggested, with Rufous-tailed Hummingbird (Amazilia tzacatl) and Loja Hummingbird (Amazilia alticola), given extensive sympatry with former. Formerly listed as Amazilia cinnamomea, but this name was unavailable. Subspecies graysoni has sometimes been considered a separate species. Validity of subspecies diluta has been doubted because of intergradation towards nominate birds. Name saturata is synonym of corallirostris. "Amazilia bangsi", known from a single Costa Rican specimen, is hybrid of present species and Rufous-tailed Hummingbird (Amazilia tzacatl). Populations from Yucatan, Honduras, Nicaragua and Costa Rica, formerly attributed to nominate, are more appropriately placed in corallirostris on basis of morphology and biogeography.
The following 4 subspecies are recognised:
diluta van Rossem, 1938 - North-western Mexico (Sinaloa, Nayarit).
graysoni Lawrence, 1867 - Is Tres Marías (off western Mexico).
rutila (DeLattre, 1842) - Western and south-western Mexico (Jalisco to Oaxaca).
corallirostris (Bourcier & Mulsant, 1846) - Southern and south-eastern Mexico (from Chiapas and Yucatán) to Costa Rica.
