Based on a model of future deforestation in the Amazon basin, and the species's susceptibility to habitat fragmentation and disturbance, it is suspected that its population will decline by 25-30% over the next three generations, and it has therefore been uplisted to Near Threatened.

12cm, 11g. Pale grey-brown crown, weak white supercillium and white streaking on greyish ear coverts. Mantle and upperwings mid-grey. Long tail often held slightly cocked, pale grey with about 6 black cross bars along it's length. Whitish underparts.
Similar spp. Previously considered conspecific with Grey-mantled Wren Odontorchilus branickii, but the latter has darker and more heavily streaked crown and face and typically has more bars along the length of the tail. Also differs in habitat and vocalisations. Voice Loud series of notes on the same pitch, slower and more separate than the trill of O. branickii. Call is a high-pitched "swee".
