The dataset comprises the Skylark flight song data of the project "Novel ideas to further expand the applicability of rhythm analysis " written by Burchardt, L.S.; Briefer, E. F. and Knörnschild, M. Time information on song elements of 14 flightsong sequences of 14 Skylark males are included. The songs were recorded by E. F. Briefer and were originally published here: Briefer, E., Rybak, F., Aubin, T. (2008). When to be a dear enemy: flexible acoustic relationships of neighbouring skylarks, Alauda arvensis. Animal Behaviour, 76, 1319-1325. doi:https://doi.org/10.1016/j.anbehav.2008.06.017 and Briefer, E., Rybak, F., Aubin, T. (2010). Are unfamiliar neighbours considered to be dear-enemies? PLoS One, 5(8), e12428. doi:https://doi.org/10.1371/journal.pone.0012428 Timestamps of the analyzed sound sequences are given, namely the start and the end of sounds. Furthermore, the corresponding ID (i.e. sl01 for Skylark 01) and IOIs (Inter-Onset-Interval, the duration between the start of one element to the start of the next element in the sequence) are given. The data was used to test new methods of rhythm analysis in animals' acoustic signals, especially to develop the universal goodness-of-fit value ugof. Rhythm analyses that were run on the data include Fourier analysis and IOI analysis as well as the visualisation with recurrence plots.
