Abstract: The data was collected in two different forests- coniferous and leafy. In each was selected 3 research plots. There was hanged the special investigation nesting boxes designed for passerine birds . Studies revealed nesting ocupation trends over the years . It was found that after a commercial thinning ocupation of nest boxes reduces in the pure coniferous and leafy forest stands. Also observed the nest box ocupation decline at the fourth year ( 2013 y.). Since start of the study they had lost their strength and safety characteristics , for that reason ocupation decreased by 27 % compared to 2011 and 2012 data. 88 It was found that various types of Parus in deciduous stands, consist 66.7 %, and Ficedula hypoleuca consist only 33,3%. We have diferent results from the pine forest, there are 72 % consists of Ficedula hypoleuca and only 28 % of Parus. It is because of birds different needs for habitats and environment. After thinning cuts, next year, ocupation level of nest boxes is decreasing , due to changes in environmental conditions, and nutritional base, it decreases by 31%
