Subspecies
Sister species of Rufous-breasted Hermit (Glaucis hirsutus), and these two often considered conspecific, but they meet in western Panama and western Colombia without interbreeding. Present species probably had continuous distribution in past, but now interrupted by Rufous-breasted Hermit (Glaucis hirsutus), by which it is presumably being gradually replaced. Slight size and weight differences exist between the two discrete populations, Central American birds having longer wings than South American ones, but plumage coloration identical. South American populations sometimes separated as subspecies columbiana.
