- Аннотация: We present results of our long-term research on the song dynamics of the Thrush Nightingale (Luscinia luscinia) in the city of Moscow and the Moscow region. The research covered three populations located 50–100 km apart from each other and lasted for a total of 11 years. We present data on the between-year variability with respect to the frequency, time, and structural features of homologous elements in the song types observed in the three studied populations. We identified two types of dynamics in the vocal repertoire of the Thrush Nightingale. The first type included abrupt shifts, wherein some song types disappeared from the population repertoire and other song types appeared instead. The second type of dynamics involved gradual interannual changes in the fine structure of individual song types. We show that such changes occurred surprisingly synchronously, not only in the majority of males in a given population but also encompass large areas, and manifested themselves in parallel, even in distant populations. The behavioral mechanisms underlying the rapid transmission of vocal patterns between distant populations remain unexplored. As a possible explanation, we hypothesize the existence of vocal exchange between individuals in common wintering grounds.
