Ocellated piculet Ocellated piculet The ocellated piculet ("Picumnus dorbignyanus") is a species of bird in the family Picidae. It is found in Argentina, Bolivia, and Peru. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest. It was first described in 1845 as "Picumnus d’Orbignyanus" by the French ornithologist Frédéric de Lafresnaye, being named in honour of the French naturalist Alcide d'Orbigny, but since then has been largely mis-spelt as "P. dorbygnianus". It hybridizes with the white-barred piculet where their ranges overlap. The adult ocellated piculet is long. The sexes are similar apart from the forecrown which
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
