Adult males can be confused only with Allen's Hummingbird. Rufous-backed males are certainly Rufous Hummingbirds, but care should be taken as some Rufous have variable amounts of green on the back and crown. Females and immatures are easily identified as a Selasphorus by the rufous in the tail. Female and immature Broad-tailed Hummingbirds have less rufous on the inner tail feathers, whitish, not rusty undertail coverts and more blue-green backs, as well as being larger with different calls. Female and immature Calliope Hummingbirds are smaller with shorter bills and less rusty backs. Rufous and Allen's females and immatures are inseparable in the field.
