The humid areas are located in the lower altitudes and plateaus of the GSP, near Atlantic Forest, being a transition area between Cerrado and the aforementioned biome ( IAP 2002 ). Bioacoustics ( Figure 6a–b ) Males sing during the day and at sunset. Duration of pulses: 15.6 ± 0.83 ms (13.35–17 ms); duration of echemes: 1.63 ± 0.19 s (1.13– 1.8 s ); mute interval between echemes: 22 ± 5.7 s (14–31 s); bandwidth: 16 ± 1.3 kHz (14–20 kHz); peak frequency: 16.7 ± 2.3 kHz (11.6– 23.2 kHz).
