Male Varied Thrushes sing a whistled, flutelike, sometimes burry tone on a single pitch. They sing mainly in the morning and evening, usually from the top of live conifers. Each song lasts about 2 seconds and is followed by a pause of 3–20 seconds. Successive tones may be on different pitches. This cycle is repeated for 10–15 minutes, until the bird flies to a new perch and starts again.
Both males and females make a variety of calls, usually in aggression or defense. Those calls include a short trill, a harsh churrr, and a series of low chect notes.
