The characteristics include: 1) song length (total length of song from beginning to end, in seconds), 2) total number of syllables, 3) number of unique syllable types, 4) trill rate (total syllables/song length), 5) average number of notes per syllable, 6) average number of frequency changes (directional change, either ascending or descending) within a syllable, 7) number of frequency changes between syllables within the song, 8) peak frequency (dominant frequency, level at which the most energy is expelled within the song, in Hz), and 9) low (kHz) and 10) high (kHz) frequencies at which the amplitude exceeded -24dB relative to the peak frequency, and 11) frequency bandwidth (kHz) as the difference between high and low frequency. Songs were collected 1976-1978 (1970s), 2001-2004 (early 2000s), ...
