Spectrograms and oscillograms of the different types of advertisement calls present in Pristimantis huicundo. A inharmonic call (Not collected, 10 °C air temperature, 61% relative humidity) B downward call (DHMECN 13777, SVL 17.7 mm, 9.8 °C air temperature, 96% relative humidity) C single call (DHMECN 13791, SVL 22.4 mm, 9.7 °C air temperature, 77% relative humidity). Spectrograms obtained using the Hann window at 99% overlap, 256 samples of FFT size and 3 dB filter bandwidth of 248 Hz.
