Fig. 7: Song diversity versus imitation.
From: Balanced imitation sustains song culture in zebra finches
a Vocal state abundances in pupils pooled over birds with lowest (bottom quartile) song diversity (dotted line) vs. top quartile (solid line). b Same as a for the bottom (red) and top (green) quartiles of tutor song influence. c–e Mean tutor’s song features versus pupil’s song features for pitch (c), frequency modulation (d), and Wiener entropy (e) for the top influences (green dots, top quartile) and for bottom influences (red dots, bottom quartile). Plotted at the bottom are histogram lines of tutor features for top and bottom quartiles. f–h Box plot distribution of mean song features in four colonies for pitch (f), frequency modulation (g), and Wiener entropy (h). Each marker represents the mean value for one bird. Green shaded areas correspond to top influence feature ranges in colony RU 2019 (this study), whereas red shaded areas correspond to bottom influence feature ranges in colony RU 2019 (n = 149 birds). In the box plots themselves, the red line is the median; Orange fill are the upper and lower quartiles; Blue fill is the minima and maxima. About 20% of the RU 2019 colony are descendants from the RU 2002 colony (Rockefeller Nottebohm Lab; n = 42 birds). The remainder of the 2019 colony originated from Duke University. Colony 3 is from the University of Southern California (Bottjer Lab; n = 48) and Colony 4 is from Cornell University (Regan Lab; n = 77). Source data for this figure is in Supplementary Data File 1.
