Small yellow-bellied trogon of mature rainforest. Males are green with a blue head and breast and yellow eye ring, females dark gray with a broken white eye ring. Both sexes have yellow belly. Found in a variety of forested habitats, but usually a fairly uncommon species; most common in mature upland rainforest. Song is an even series of high “whew” notes, often sounding vaguely disyllabic, “whe-ew”; usually higher pitched and less breathy than Black-tailed.
