Abstract

Breeding season vocalizations in anuran amphibians offer crucial insights into reproductive behaviour and habitat selection. In this study we investigated calling sites and courtship calls of Austrochaperina robusta and Pseudophryne covacevichae, two terrestrial frog species native to northern Australia. Surveys revealed that 87% of calling A. robusta males were in direct contact with logs, roots, or trees. We recorded and described for the first time the courtship call of A. robusta, which was characterized by two short, high-pitched chirps and features unique acoustic properties. Of 140 P. covacevichae males, 10% were in proximity to egg clutches. The P. covacevichae courtship call is distinct from the advertisement call and consists of short, high-pitched chirps.
