This study presents seasonal dynamics of Acrocephalus species at Cernek (41º36'N, 36º05'E) and Aras (40º07'16''N, 43º35'00''E) ringing stations. These places differ in habitat and topography. The aim of our study was to compare the seasonal dynamics, passage density and age structure of the Acrocephalus species caught at these stations.

Data were collected with the standards of the SEEN (Busse 2000). The analyses showed that Acrocephalus species were ringed in higher density in Aras than in Cernek. At both stations in autumn Acrocephalus scirpaceus and in spring A. arundinaceus were the dominating Acrocephalus species. The seasonal dynamics of A. scirpaceus was different in spring and in autumn. There was a significant age differences in A. arundinaceus at both stations.
