A vocalization that may be the song of Yellow-crested Tanager is a series of high buzzy dzz dzz dzz notes (Lane, in Schulenberg et al. 2010; Hilty 2011).
A call of Yellow-crested Tanager is a high-pitched, upslurred shrill tswee (Isler and Isler 1987). This note is repeated at a constant rate of delivery in about 5-6 second intervals. Additionally, a female was recorded delivering a repeated upslurred note while bathing.
