A tiny, short-tailed woodpecker with a short, chisel-like bill. Distinctive within limited range in southwest Ecuador and northwest Peru. Note the heavy black-and-white markings on the underparts, which separates this species from the plain-breasted Olivaceous Piculet. Typically occurs in drier habitats than Olivaceous, such as deciduous forests and scrubby thickets. Forages by clinging to branches and vines in the lower and mid-levels, usually singly or in pairs.
