The female is similar, but her throat is white with dusky spots.
Young birds resemble the female but have buff fringes to the upperpart plumage.

Similar Species

Scintillant Hummingbird - the male is distiguishable by the orange gorget, but the female is almost identical. Look for a shorter section of rufous and brighter white tips on the Volcano's rectrices. The Volcano occurs at higher elevations, but in an area of range overlap, distinguishing the females can be very difficult in the field.

The diet includes nectar, taken from a variety of small flowers, including Salvia and Fuchsia, and species normally pollinated by insects. It also takes some small insects.
