Poorly known. The most frequent vocalizations are calls, described as "weak chit and seet notes" like those of other species of Tangara (Hilty 2003), or as "high ti and tchew notes" (Lane, in Schulenberg et al. 2007). What may be the song is "a high, buzzy tik tik-tik dzheeweew" (Lane, in Schulenberg et al. 2007).
