 abstract={In a number of forest biotopes an estimation was carried out of the distribution, abundance dynamics, overlapping of territories of various bird species, as well as of the interactions between species of a community. The interspecific competition has been found to have a significant influence on the numbers and the distribution of birds, its intensity being modified by the environmental conditions. In the community, groups of species have been distinguished with strong competitive interrelations between them. They were given the term of competitive associations. Within the competitive associations a quantitative compensation was found, that is, a stability of numbers in the association, in comparison with the great variability of the abundance of the different components of the association in the successive years during the search.},
