The advertisement calls of three hylid frogs from Hispaniola

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.
