White-browed piculet descending to the ground, where it may hop for short distances. This bird uses pieces of bamboo to make its nest. It picks up bits of broken bamboo with its feet, and uses its beak to pull away partially broken fragments. Breeding takes place between March and July. The white-browed piculet is described as a fairly common bird and has a very extensive range. No particular threats to this bird are known and, in the absence of evidence to the contrary, the population is believed to be stable. For these reasons, the International Union for Conservation of Nature has assessed
White-barred piculet and heavily degraded former forest. The white-barred piculet was first described in 1825 by the Dutch zoologist Coenraad Jacob Temminck. It was given the name "Picumnus cirratus", the specific name meaning "curly headed", "cirrus" being Latin for a ringlet or curl. Molecular studies show that it is the sister species to "P. temminckii" and also closely related to "P. dorbignyanus", and at different times these species have been treated as synonymous. Six subspecies are recognised; "P. c. confusus" found in southwestern Guyana, northern Brazil and French Guiana; the Marajo piculet, "P. c. macconnelli" found in the eastern Amazon region of
