The Purple-throated Euphonia is found in a variety of habitats across its broad range, which stretches from eastern Colombia south to eastern Brazil and northern Argentina. This euphonia usually is found in gallery forest and at the edge of humid lowland forest, but in Amazonia it is found only in river-edge habitats, and in some regions it the euphonia of deciduous forest and of dry scrub. The male is blue-black above with a deep purple head and throat. The forecrown and underparts are bright yellow. The female is olive above and whitish below with yellow on the forecrown and flanks.
