The Beryl-spangled Tanager gives high-pitched sit and chit notes (Hilty 2003). These notes are delivered either alone and in excited bursts that resemble the calls of other tanagers of the the genus Tangara (Hilty 2003). Lane (in Schulenberg et al. 2007) also describes a slightly descending tsew.
The song of Beryl-spangled Tanager also is high-pitched, thin, and faint, described as "see sit sit, see see tzle ‘tzle ‘tzeet" (Hilty 2003).
Juvenile Beryl-spangled Tanagers have been recorded begging for food.
