| Summary / Zusammenfassung | In a project of several years duration, we have undertaken an analysis of the song of the Skylark Alauda arvensis both qualitively and quantitatively. The complicated flight song of these species was studied by using statistical methods, primarily Jaccard's similarity index. There is a clear hierarchy of a species-, population- and even individual-specific song pattern. The dialect areas are surprisingly small and on the level of subpopulations which are only a few kilometers apart. As efficient indicators of identity, these song dialects seem to be connected with important parameters such as territoriality, mating system, individual age and philopatry. | ||||||
