Complete seasonal replacement of European robin populations takes place in the Crimea: local birds of the subspecies E. r. valens depart from the peninsula to be replaced by birds of the nominative subspecies E. r. rubecula, which arrive for wintering. The overall population dynamics of the European robin in the Highland Crimea are determined by seasonal changes in the abundance of local birds, fluctuations in the abundance of birds from northern populations, or variation in the ratio between these groups of birds during their staying together in the Crimea during the periods of seasonal migrations.
