The Emerald Tanager has a limited vocal range. The most frequently heard vocalizations are calls, ranging from a sharp tsit to a raspy, penetrating, moderate to high pitched jree or dzreee (Isler and Isler 1987). Calls of Emerald Tanagers are described as burrier than those of Golden (Tangara arthus) or Silver-throated (Tangara icterocephala) tanagers (Hilty and Brown 1986). Calls are repeated randomly or sometimes accelerated as a twitter, possibly when interacting aggressively (Isler and Isler 1987). Probable song involves burry high zeeeeee notes repeated regularly with 3 s pauses, lasting 2-3 minutes (Isler and Isler 1987).
