Figure 3

Spectrogram of one song of a black redstart (Avisoft-SASLab Pro, sample rate 22.05 kHz, FFT = 256 points, hamming-window, overlap: 50%). Song parts are indicated on top of the spectrogram. Measures analysed were durations of parts A, B, C, of the total song and the pause duration between A and B; the number of elements of part A and C; the frequency bandwidth and the maximum frequency of part A, B, C (see text and [26] for further details).
