Voice - The song is a repetitious series of brief robin-like phrases separated by short pauses. The first phrases have a rising inflection like a question. The next phrase descends, like an answer. The song has been transcribed as "cherr-o-wit, cheree, sissy-a-wit, tee-o" or See me? Here I am! Up here. See? Vireo!. The call is a nasal chway and it utters a harsh chatter.
