The bar-breasted piculet is generally found in humid forests, including "terra firme" and "várzea", and are generally seen within such areas in the edges, second growth, and clearings.

Black-dotted piculet Sucre, a few have finely barred chests. Rare individuals with scaly throats and pale buffy (rather than yellow) underparts resemble the scaled piculet, which can be distinguished by its scaly lower underparts. The crown is black with narrow scarlet streaks on the forepart and conspicuous white dots on the rear part, or throughout in some females. The upperparts are light olive-brown, slightly yellowish, with dusky spots on the shoulders and back. The song is "2 to several extremely high, thin notes, each slightly lower than the preceding, "tseeet, tseeet, tsee," etc." Possibly it is also used as a contact call.
