摘要

The age-related variability of the frequency and structural-temporal parameters of the advertising song of Ficedula hypoleuca males in natural habitats and the urban environment were analysed. In the natural habitats, the range of male song frequencies, the maximal frequency, the number of figures, and the length of the song decreased from the third year of life. Similar age-related song changes in urban birds are observed earlier, from the second year of life. Urban birds have shown that the higher minimum song frequency increases with age, adapting the song to noise pollution.
