Similar species

Broad-billed Hummingbird could occur as a vagrant on the islands where this bird exists. In general this differs in having a sparkling dark blue throat (cf sparkling green), although images show Tres Marias Hummingbird can have some blue feathers admixed. Images also show that the extent of the dusky undertail coverts is not consistently different between the two species.
