The adult Rufous-tailed Hummingbird is 10–12 cm (4–4.8 in) long and weighs approx. 5.2 g (0.2 oz). The throat is green (edged whitish in the female), the crown, back and flanks are green tinged golden, the belly is pale greyish, the vent and rump are rufous and the slightly forked tail is rufous with a dusky tip. The almost straight bill is red with a black tip; the black is more extensive on the upper mandible, which may appear all black. Immatures are virtually identical to the female. The call is a low chut, and the male’s song is a whistled tse we ts’ we or tse tse wip tseek tse.
