The Perija starfrontlet is about long including its bill. Adult males have a blackish crown, a glittering green forehead, and a small white spot behind the eye. Their upper back is shining dark green that transitions through greenish copper to the golden orange rump. The throat and breast are glittering green and the throat has a small deep blue patch. The rest of the underparts are variable, from glittering copper to reddish gold. The wings are dark with a rufous patch on the tertials. The slightly forked tail is golden bronzy green. The adult female's forehead is plain green and the postocular spot white to buffy orange; the rest of the upperparts are colored like the male's but are duller. The throat is buff and has green spots on its sides. The breast is mottled buff and green. The rest of the underparts are mostly cinnamon with a fiery gold belly and a coppery gold vent area. Juveniles resemble adult females.Palacios, C. (2022). Perija Starfrontlet (Coeligena consita), version 1.0. In Birds of the World (N. D. Sly and S. M. Billerman, Editors).
