Green-and-gold Tanager is one of the 45 species within the genus Tangara. The species occurs in western Amazonia, where it is found from southeastern Colombia and southern Venezuela south to northern Bolivia and western Brazil. It is a common species in the lowlands, typically found below 900 m, where it forages in mixed-species flocks with other species of tanagers and antshrikes. This tanager primarily forages in the mid-story and canopy of humid forest and forest edge, although occasionally it also frequents the understory. Green-and-gold Tanager is most similar to Blue-whiskered Tanager (Tangara johannae) and Emerald Tanager (Tangara florida), which share green plumage with black striped backs. The sexes are slightly dimorphic. Males are brilliant green above with a yellow crown and rump, and black streaks on the back; the forecrown and sides of the face also are black, forming an incomplete mask. The center of the breast and belly are yellow, but the sides of the breast and flanks are more or less washed with green. The rectrices are black, with narrow green or greenish blue margins. The female is similar but duller in appearance, with a greener crown. Green-and gold Tanager is omnivorous, with a diet that includes fruits (mostly berries) and insects. There is little information about the breeding of Green-and-gold Tanager, but the nest is built of dried leaves and is placed in an understory tree or shrub, and contains two eggs.
