T. Kirin, J. Kralj, D. Ćiković, Z. Dolenec: HABITAT SELECTIONAND SIMILARITYOF THE FOREST ...Šumarski list br. 9–10, CXXXV (2011), 467-475 sects is greater on older trees and significantly greater on the oak trees in comparisons to other tree species (Southwood1961). Species feeding in canopy were positively correlated with quantity of shrub proving that their feeding area is equally canopy and higher shrub layer. Species feeding on ground avoided foreststands with rich shrub layer because reduce the availability of open ground.Positive correlation with densities of species nesting in the canopy and average tree basal area was explained bySherryandHolmes(1985). They state that the tree basal area is a good index for es timating the leaf surface of the tree which should be important factor for species inhabiting canopy. It can be concluded that for habitat selection of forest birds on the larger spatial scale both floristic and structural composition are important, while on smaller scale the differences in structural characteristics had higher impact to bird communities than floristic differences. Structural characteristics related to forest age had the most pronounced effect to the densities of different ecological groups of birds.
