Dawn song start time in relation to breeding stage. Individual dots visualize raw data values (i.e. one value for a recording per individual per day). The maximum dawn song start time was 2793 s and the minimum 77 s before sunrise (Mean +/− SD: 1923 +/− 684). Start time in seconds before sunrise was inverted (using a round number close to the maximum start time) and log-transformed
