Figure 4. Example bouts of aggression vocalizations.

Example waveforms (upper trace) and spectrograms (lower trace) of example vocal sequences emitted from the same bat during low aggression (A) and medium aggression (B) contexts. All syllables were classified as DFMs. The medium aggression bout lasts for an additional 2.1 s. (C) Example high aggression bout from a different bat, with syllable classifications above each waveform. Note that the rBNBl syllable includes a bifurcation of torus near the beginning of the syllable. Peak amplitude of the entire bout was normalized.
