In this study, we provide detailed descriptions of the previously unknown advertisement calls of Osteopilus dominicensis and Hypsiboas heilprini, as well as a complete redescription of that of O. pulchrilineatus, three of the four hylid frogs known from the Caribbean island of Hispaniola. The call of O. dominicensis is composed of a single multi-pulsed note with a mean dominant frequency of 2058 Hz. In contrast, the call of O. pulchrilineatus consists of two different pulsed notes (the second repeated many times in one call) with a mean dominant frequency of 2950 and 2060 Hz, respectively. The call of H. heilprini, in turn, is a trill consisting of multi-pulsed notes (emitted in a consecutive series) with a mean dominant frequency of 1738 Hz. We compare these three calls to those of closely related species.
