(C–E) Comparisons of vocalization duration, frequency bandwidth and mean frequency, respectively, between the Anesthetized-male and Solo-female-odor conditions, and between the Anesthetized-male and Paired-female-odor conditions. (F–I) Proportions of complex vocalizations, upsweeps, downsweeps and flats in the Solo-female-odor, Anesthetized-male and Paired-female-odor conditions.
