  • Rufous Hummingbird is very similar; females and immature birds nearly indistinguishable in the field. Male Rufous Hummingbird has an orange back and rump. Beware the rare Rufous Hummingbird male with a green back; if it has any completely rufous feathers, not rufous-edged, on the back, it is a Rufous Hummingbird. The outermost tail feather, difficult to see in the field, is broad in all plumages of Rufous Hummingbird.
  • Female Broad-tailed Hummingbird and Calliope Hummingbird have buffy sides and rufous in the tail. Calliope is pale buffy on the sides, has little rufous in the tail, and has a very short tail, about the same length as the wings when perched. Broad-tailed has paler buffy sides, has little rufous in the tail, and lacks the central red spot on the throat.
