Thamnophilus amazonicus

Río Yavarí, north-east Peru


Previously thought to be closest to the “T. punctatus group” (see that species, above), and race huallagae of T. punctatus formerly included in present species. Recent molecular analysis#R, however, indicates that present species belongs in a group with T. insignis (which see) and relatives. Plumage variation mostly clinal. Form cinereiceps fairly distinctive in appearance (both sexes), but no evidence of vocal differences from other races. Five subspecies currently recognized.
