The Influence of Natural and Man-Made Landscape Conditions on the Formation of Biological Heterogeneity in the Population of the Great Tit (<i>Parus major L.</i>)
The paper studies the size of the clutch and morphometric features of eggs, the growth and development of chicks of the great tit. Their dependence on many factors regulating the number of individuals and influencing the formation of the population as a whole is shown. The impact of exogenous factors on birds is perceived differently, due to their heterogeneity, which subsequently manifested itself in the ratio of large and small clutches, and a decrease in their number.
