There are three different normal call notes for the Paradise Tanager: a sharp, moderate-pitched chak, a thin rising zeee that is said singly together or in irregular series, and a high sizit that can be sung or be given in rapid series, usually when taking flight (Isler and Isler 1987, Restall et al. 2007). In the morning, the Paradise Tanager gives a Dawn Song, which is a repeated chak-zeet every two seconds (Isler and Isler 1987, Restall et al. 2007). In In some cases females vocalize when soliciting copulation; this may occur in the wild but to date is reported only in captive populations (Tucker 2002). This song is described as a series of continuous notes descending in pitch, containing an average of 20 notes, sounding phonetically as zee (Tucker 2002).
