The Gray-breasted Wood-Wren forages in the understory of Andean montane forest. Its white eyebrow and gray throat and breast are useful field marks.
The upperparts are reddish brown, with a white eyebrow; the throat and breast are gray, and the short tail has dark bars.
It often forages alone in the understory of mature montane forest and is more often heard than seen, according to the account.
