This is an extremely soft chat between three individuals in dense vegetation, at a height of 0.3 m. Though I was at ~ 4 m from them, the vocalizations are so soft that not even the parabolic microphone can pick them up with a high signal-to-noise ratio. I was only able to make contact with the male and the female for about 6 s. They exchanged these soft vocalizations before the female left uttering a call a bit louder but not structurally different from the ones they were giving. A juvenile was nearby at all times. Normalized at -1 dB. Filtered with a 500-Hz highpass filter with a 3 dB passband attenuation and a 40 dB/decade rolloff.
