White-barred piculet White-barred piculet The white-barred piculet ("Picumnus cirratus") is a species of bird in the family Picidae, 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 Tapajós River. A small, apparently isolated population is found in southern Guyana and adjacent Roraima. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests,
White-barred piculet northeastern Brazil; "P. c. thamnophiloides" found in southeastern Bolivia and northeastern Argentina; "P. c. tucumanus" found in northwestern Argentina; the Pilcomayo piculet, "P. c. pilcomayensis" found in southeastern Bolivia, Paraguay and northeastern Argentina; and the nominate subspecies "P. c. cirratus" found in southeastern Brazil, southern Mato Grosso and eastern Paraguay. The taxonomy of this species is difficult; the races "pilcomayensis", "thamnophiloides" and "tucumanus" intergrade in northern Argentina and are sometimes considered a separate species, and "pilcomayensis" intergrades with "cirratus" in eastern Paraguay. The northern subspecies, "confusus" and "macconnelli" may also be a distinct species. The white-barred piculet also hybridizes widely
