Bioacoustics ( Fig. 3D–F ): The calling song of this species is complex, as different types of syllables are produced. Each echeme is composed by a sequence of nine to 15 trios of syllables. Each trio initiates with a very short syllable, that is followed by a long one, and by the third syllable that presents an intermediary duration. It is noteworthy that each echeme always finishes with a long, i.e., the second, syllable.

Dominant frequency: 13 ± 1.1 kHz.

Bandwidth: 5.7 ± 2.8 kHz.

Duration: Pulse: 0.07 ± 0.06 s; Syllable: 0.32± 0.02 s; Echeme: 5.4 ± 2.2 s.

Mute interval: Syllable: 0.05 ± 0.02; Echeme: 28 ± 7 s.
