Bar-breasted Piculet Picumnus aurifrons

Small, greenish-brown piculet. Light olive brown, with horizontal barring on the breast changing to vertical streaking on the belly, and a black-and-white speckled crown. Males have a yellow forehead patch. Forages singly or in pairs around the midstory and canopy of secondary rainforest, sometimes joining mixed-species flocks with tanagers and other species. Its song is a high, two- or three-note “sweet, sweet,” similar to the songs of other piculets.
