Although its range stretches from southern Colombia south to Bolivia and east into western Brazil, Rufous-breasted Piculet is uncommon and local. They are inconspicuous, and usually seen quietly foraging on small branches and vines. Primarily inhabitants of river-edge and second-growth forest, they generally stay in small trees of the understory. The bright chestnut coloration on the breast is distinctive, but note also the green back and finely dotted crown. They are usually encountered singly or in pairs, and often join mixed foraging flocks. In general, Rufous-breasted Piculets are not particularly vocal, but their drum is a series of several rapid bursts.
