Their tail is dusky with olive edges on the feathers. Voice: The rufous-rumped antwren's song is described as "a rapidly uttered, high-pitched tsii-tsii-tsi-tsi-titititititititi that accelerates into a fast chipper or trill" and similarly as "an accelerating, rising series of high, thin notes ending in a falling, chippering trill: tew tew-tew-ti-ti-ti't't't't't't'ti".
