Revisiting the advertisement call features of Scinax montivagus (Anura: Hylidae)

Abstract

In the present study, we revisit the advertisement call of Scinax montivagus based on new recordings from Rio de Contas, state of Bahia, Brazil. The species’ call consists of a single type of multipulsed note of relatively short duration (mean = 192 ms), having two non-harmonically related emphasized frequency bands. The dominant frequency corresponds either to the lower or the higher band, or it may shift between both along call emissions. Herein, we assess and discuss call features that diverge from what is in the literature and also provide further details on the species call. We reinforce that detailed and standardized advertisement call descriptions of different Scinax species would contribute to acoustic diagnosis between them.
