The White-barred Piculet (Picumnus cirratus) is a species of bird in the Picidae family, the woodpeckers, piculets, and wrynecks. It is found in south-eastern Brazil south and west to the Pantanal, and into south-eastern Bolivia, Paraguay and northern Argentina. A disjunct population occurs in the coastal parts of French Guiana, south to the Brazilian state of Amapá and west along the lower Amazon River up to around the Tapas River. A small, apparently isolated population is found in southern Guyana and adjacent Roraima.
