title: Seasonal replacement of populations and abundance dynamics of European robins, Erithacus rubecula (L.), in the Highland Crimea
abstract: 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.
