Olivaceous piculet Olivaceous piculet The olivaceous piculet ("Picumnus olivaceus") is a species of bird in the family Picidae. Etymologically, piculet is as a double diminutive of the Latin "picus", "woodpecker", see also Picus. In Greek, δρύοψ is woodpecker, which shares its roots with δρῦς, 'tree'; 'oak' and Druids. Found in Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Nicaragua, Panama, Peru, and Venezuela, its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and heavily degraded former forest. Upper parts plain olive-brown, crown and nape spotted white on blackish, tail short, not sharp-tipped, black with a prominent yellow center
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
