Their tail is rufous; it is graduated and the feathers have pointed tips. Voice: The creamy-crested spinetail's song is "a loud, ascending-descending series of semi-musical notes: tch, tch, tleep-chee-chee-cheechee-ee-ee-ee-ee-trrrr" and is often given in duet. Its calls include "a rising tlee'lee", "a loud, semi-whistled dew", and a "rapid series of tleep notes".
