The buff-tailed coronet is 11 to 12 cm (4.3 to 4.7 in) long and weighs 7.3 to 8.8 g (0.26 to 0.31 oz). Both sexes have a short, straight, black bill and a small white spot behind the eye. Males of the nominate subspecies are mostly shining green, with a buff belly accented by green spots. The underwing coverts are cinnamon and show in flight. The central tail feathers are bronzy and the rest are buff with bronze tips and edges. It has small white tufts on the legs. The nominate female has more buff on the underparts and the bronze of the tail is less extensive. Voice: What is thought to be the buff-tailed coronet's song is "a continuous series of single high-pitched 'tsit' notes." It sometimes sings with several others of its species nearby. It also makes a "squeaky twittering, with rising piping notes and stuttering rattles," especially when interacting with other hummingbirds.
