). Most of the call energy is between 850 and 1150 Hz (one harmonic). The call has a general downward FM (45B, E, F). Additionally, calls have an up-downward FM in the first third of the call duration, leading to arc-shaped bands in this part of the call, and a short upward FM at the end (45B, E, F). The general downward FM and the initial updownward FM result in S-shaped harmonics when considering the entire call. There is no PFM.
