Woodcreepers (Dendrocolaptidae)
Amazonian Barred Woodcreeper (Dendrocolaptes certhia) - HBW 8, p. 419
French: Grimpar barré
German: Amazonien-Bindenbaumsteiger
Spanish: Trepatroncos Barrado Amazónico
Other common names: Concolor(ed) Woodcreeper (concolor)
Taxonomy: Picus certhia Boddaert, 1783, “Cayenne”.
Until recently considered conspecific with D. sanctithomae; separated on basis of vocal, behavioural and morphological differences. Race concolor sometimes treated as a separate species, but vocal and morphological data suggest that it is instead a pale, weakly barred representative of present species; characters of birds from R Tapajós E to R Tocantins (NC Brazil), described as race ridgwayi, apparently represent introgression between concolor and medius. Birds from E Peru showing characters of polyzonus may instead reflect hybridization between .. View all taxonomy...

Birds from E Peru showing characters of polyzonus may instead reflect hybridization between radiolatus and juruanus. One study indicated genetic differences between radiolatus and concolor as great as or greater than those between it and D. sanctithomae. Six subspecies recognized.
