It is only 6.5–8 cm (2.6–3.1 in) long, including the bill. The male weighs 2 g (0.071 oz) and the female 2.3 g (0.081 oz). This is one of the smallest birds in existence, marginally larger than the bee hummingbird. The black bill is short and straight. The adult male scintillant hummingbird has bronze-green upperparts and a rufous and black-striped tail. The throat is brilliant red, separated from the cinnamon underparts by a white neck band. The female is similar, but her throat is buff with small green spots and the flanks are richer rufous.
