Breeding biology, age structure and other population parameters of the Common Rosefinch, collected on the Courish Spit of the Baltic Sea, are presented. The results are compared with similar population characteristic in different parts of the range. All materials, especially the proportion of breeding yearling males, are discussed in connection with the process of range expansion of the species. The expectation of greater proportion of yearling males in new areas did not proved.
