Its bill is black and mostly straight with only a slight downward curve and measures from 1.8 to 2.5 cm (0.71 to 0.98 in). The body mass can vary from 4.8 to 5.6 g (0.17 to 0.20 oz). Among standard measurements, the wing chord is 5.8 to 6.8 cm (2.3 to 2.7 in) and the tail is 3.5 to 4.3 cm (1.4 to 1.7 in). It is shining green above with a glittering violet ear-patch on the sides of its neck. Voice: Solitary males sing from high, exposed twigs in their territory every day. Their song is a monotonously repeated sharp and dry "tsu-tzeek" at a rate of about one call per second.

Its principal song is "a long series of monosyllabic metallic chips, 'djit...djit...djit...' or 'tlik...tlik...tlik..'." It also sings "a medley of chips, squeals, gurgling sounds and short warbles" during aerial display. Its call is "a repeated short dry rattle 'drrr...drrr...'."
