a Markov diagrams of syllable transition (bi-gram) before and after the conditioning of syllable repetition. b Tri-gram syllable transition matrix before (left) and after (middle) the conditioning, and the difference of before and after (right). This subject was conditioned to increase syllable repetition “c”. c Spectrograms of songs before and after conditioning. The repetition occurred at three loci of single song bout in this example. d Change of repetition locus where the maximum repetition occurs in a song bout. The heatmap shows the song rate change (%) before and after conditioning for each bird.
