- Order: Piciformes
- Family: Picidae
Plain-breasted Piculet is resident is a restricted area in the western Amazon Basin. The distribution of this species is centered on the Río Ucayali in eastern Peru, and from there downstream along the Amazon (Short 1982, Schulenberg et al. 2010). It occurs in extreme southeastern Colombia along the Amazon (Remsen 1977, Hilty and Brown 1986). There is a single record for western Brazil at Maguiri, on the right bank of the rio Japurá, Amazonas (Sick 1997); its presence here suggests that Plain-breasted Piculet should occur along the Amazon east at least to Tefé.
Plain-breasted Piculet is entirely confined to the lowlands.
Outside the Americas
Endemic to the Americas.
Plain-breasted Piculet primarily occurs in forest on young river islands and riverbanks, but also spreads into secondary forest in mostly cleared land (O'Neill and Pearson 1974). This piculet is most numerous in the canopy of young river island forest of Cecropia with a mixture of Cassia or Albizzia/Mimosa; less commonly also in older forest of Erythrina glauca and Ficus spp., and in clumps of bushes and trees along edges of gardens and pastures (T.A. Parker, unpublished observations).
