Call notes of the male Yellow-winged Tanager are given from perch or in flight and consist of thin, strained, high-pitched “weeets” or “sseeu” that are sometimes upward-inflected. Other squeaky call notes have also been heard (Isler and Isler 1987). Their song often contains 1 or 2 introductory notes, “shee iiiiiiiiiiiiiiiiir”, and is described as being slightly reedy with a descending trill. The song may also be preceded by 1 or 2 rough notes (Hilty 2011) Songs have also been described as a 2-4 second "che-che-che-che" that is mostly flat trill, predominately high-pitched, and preceded by a single call note (Isler and Isler 1987). The same series is often repeated after intervals of 3-5 seconds (Isler and Isler 1987). Their voice has been reported to sound like a series of sparrow-like chirps, particularly similar to the Olive Sparrow (Arremonops rufivirgatus) or the Chipping Sparrow (Spizella passerina) (Sutton et al. 1950, Davis 1972, Peterson and Chalif 1973).
