Figure 2.

Twelve bar charts display different datasets labeled CBM1 to CBM12, each with corresponding sample sizes (N) and p-values. Each chart shows the frequency of use for various song types, indicated by letters (e.g., A, B, C). The x-axis represents the number of times used, and the y-axis denotes the song type. Notable variations in usage are highlighted, with some charts showing significant differences based on the p-values. Twelve bar graphs showing the frequency of different song types used across various groups labeled CBM1 to CBM12. Each graph represents the number of times specific song types, labeled with letters, were used. The total number of observations (N) and p-values are noted, indicating statistical significance in most graphs. Song types and usage frequency vary across each chart, reflecting differences in preference or occurrence.

(A) Frequency of song type use by individual males when singing to females. Each box shows the frequency of song type use for each subject male, including total songs performed (N) and significance value for deviation from random use (Chi-square GoF test). (B) Frequency of song type use by individual males when singing to males. Each box shows the frequency of song type use for a subject male, including total songs performed (N) and significance value for deviation from random use (Chi-square GoF test).
