The paper deals with intrapopulation and inter-population variability of color polymorphism of synanthropic blue rock pigeons ( Columba livia Gm., 1789) living in industrial centers of the Middle Urals. The authors have identified seasonal and inter-annual differences of color morphotypes of synanthropic blue rock pigeons, which are primarily determined by the total number of birds in clusters (flocks). With an increase of birds «concentration» in a flock, which occurs in winter, the relative proportion of the blue and the «aberrant» morphotypes increases while the relative proportion of the black-chequer individuals decreases. Density-dependent mechanisms of phenotypic structure formation of synanthropic blue pigeons populations work in conditions of significant increase of bird population in accumulations when different behavioral strategies, especially food, ensuring survival, are vividly manifested. The inter-population variability of color morphs from the geographically close localities of the Middle Ural may be determined by the degree of urbanization of the habitat, the diversity and abundance of forage resources and the technogenic load. The obtained materials may be of interest in general for the study of sustainable color polymorphism of blue rock pigeons synanthropic populations as well as for identifying and justifying inter-population differences of blue rock pigeons populations from geographically remote localities of the Urals.
