The Yellow-breasted Antwren is largely confined to the east-slope foothills of the Andes, from Ecuador to extreme southeast Peru, but is also found in the west and central Andes in western Colombia. Throughout its range it inhabits the subcanopy of humid montane forest and its borders, at 800–1900 m, and the species can be extremely difficult to observe closely as pairs often remain high above the ground within dense vine tangles. The Yellow-breasted Antwren is, like most Herpsilochmus, most likely to be detected initially by voice, a rattle-like trill that decreases in pitch and intensity towards its terminus. The species’ ecology is very poorly known, partly as a result of its secretive behavior, although the Yellow-breasted Antwren does regularly join mixed-species foraging flocks containing other insectivores, as well as frugivores.
