Males unmistakable when red crown is seen but beware of poor lighting conditions. Females and immatures are fairly large and gray breasted, and often show the distinctive rosy-red gorget color on the throat. Costa's and the two Archilochus hummingbirds are the most likely identification contenders, but are smaller with whiter breasts and different call notes.
