Taxonomy
Picus mixtus
Boddaert
, 1783,Buenos Aires, Argentina
.Previously placed in Picoides. Molecular analyses, however, indicate that this species belongs in present genus and is part of a clade which contains also V. spilogaster and V. lignarius#R. Genetically close to latter#R#R and may be conspecific, but mixtus differs in its smaller size (effect size for tail 4.15, score 2); higher and harsher long-distance trill call (allow 2); less streaked hindcrown (1); slightly more regular streaking on throat (1); less buffy-tinged underparts (1); and deeper black of plumage (ns[1]); possible overlap of breeding ranges not well documented. Races intergrade, and malleator and berlepschi may be more appropriately lumped into nominate. Four subspecies tentatively recognized.
