Abstract

The period of calling activity ofPolypedates maculatus lies between April and October. Males possess an indistinct subgular vocal sac which turns yellow during the breeding season. Mating calls type I, type II and distress calls have been identified. Mating calls type I and type II consist of a single pulse group. Type I call comprises of 7–22 pulses, whereas type II call consists of 4–6 pulses. Pulses are short. The frequency spectrum is broad and continuous. Distress calls, with 6 hormonics, are given by the females with their mouth open.
