Ramphocelus flammigerus is found primarily in western Colombia and northwestern Ecuador, particularly within humid tropical and subtropical forest edges, secondary growth, plantations, and gardens below 5,000 feet in elevation. Population trends are considered stable, and the species is not classified as endangered.

Adult males measure approximately 7 inches in length and are recognized for their solid black plumage contrasted by a bright red or flame-orange rump and lower back, with a thick, pale blue-gray bill. Females and juveniles are duller, with olive or brownish upperparts and reddish-tinged underparts. It forages in pairs or small groups, primarily eating fruits, berries, and insects. The species exhibits relatively tame behavior and often frequents fruiting trees or bird feeders in gardens. It uses open perches to call with sharp, metallic notes and short songs, especially during the early morning hours. Photographed in north-western Ecuador.
