Euphonias are members of the genus Euphonia, a group of Neotropical birds in the finch family. Euphonia contains close to 27 species. Pictured here is the thick-billed Euphonia (Euphonia laniirostris) which is distributed from Costa Rica south to southern Amazonia. Males are mainly glossy steel blue with a yellow forecrown patch that reaches to just behind the eye, and bright yellow underparts including the throat. Females are, like those of most euphonias, much duller, being olive above and yellow below.
