These yellowish green piculets have horizontal barring on the chest and vertical streaking on the belly. Several different subspecies exist throughout their large range. Unfortunately, very little is known about their life history and basic ecology. Bar-breasted piculet The bar-breasted piculet ("Picumnus aurifrons") is a species of bird in the family Picidae. It is found in Bolivia, Brazil, Colombia, and Peru. Its natural habitats are subtropical or tropical moist lowland forests and sometimes in heavily degraded former forest. The bar-breasted piculet is
Piculet of pronounced morphological similarities, but the two "Picumnus" lineages, despite having diverged long ago, are virtually alike except for head coloration (Fuchs "et al.", 2006). The Antillean piculet ("Nesoctites micromegas") has proven to be a very distinct species evolutionarily between piculets and woodpeckers (Benz "et al.", 2006) and thus is nowadays placed in a subfamily of its own. The arrangement of species in the genera follows del Hoyo "et al." (2002). Genus "Picumnus" Genus "Verreauxia" (sometimes included in "Sasia") Genus "Sasia" Piculet The piculets are a distinctive subfamily, Picumninae, of small woodpeckers which occur mainly in tropical South America, with
