Аннотация:Birdsong overlapping may either indicate communicative interaction between birds or be a simplecoincidence. We developed a program that allowed us to mathematically modulate the independent singingof birds with a given level of song rate. This permitted us to statistically evaluate whether song overlapping isa random coincidence or real acoustic interactions between birds. Analysis of automatic recording (SongMeter SM4) of singing detected the cases of reliable acoustic interactions between both conspecific and heterospecificindividuals. They account for 6% of the total singing time. The most numerous and actively singingchaffinches (in the case of singing of several individuals) suppress the singing of other species. The singingof a single chaffinch, on the other hand, can provoke the singing of other species, involving previously silentneighbors in song duels. It is possible that it is the acoustic interactions that are responsible for maintainingthe structure of the population at the end of the breeding season.
