This coefficient describes species\-specific rate of occupation of nest\-boxes as well as the contribution of the pairs nesting in them. Tree Sparrow occupied a total of 33% of A\-type nest\-boxes, its densities were positively correlated with the number of nest\-boxes, and seasonal differences in occupation rate were low for this species."]
