Figure 6
Appeasement behavior in mustached bats. (a) A male inspecting a female. (b) Inspection rate after a disturbance. The grey horizontal line shows the mean rate, and the dotted lines show the 95% confidence intervals. The rate is significantly higher in the second minute. (c) Two males “kissing.” (d) A histogram showing the temporal relationship of vocalization with the enactment of the kissing behavior. Zero time is indicated by the arrow and corresponds to the time of perceived contact of male’s nose with the genital region of the female. (e) The amplitude envelope (above) and spectrogram (below) of a QCFl syllable.
