The song is a fast, high and evenly pitched, series of tsitsitsitsitsitsitsiti, perhaps a harsher tsiTsiTsiTsiTsiTsiTsiTsiT when agitated (Ridgely and Greenfield 2001). Their call is tz or tze, which can be repeated in succession when foraging (Restall et al. 2006). Begging juveniles also rapidly repeat a high-pitched shrill tsitsitsitsitsitsitsiti. Additional audio recordings of vocalizations of White-bellied Dacnis can be heard at xeno-canto.
