Abstract:

107 bird species were recorded in 1987 and 1988 in Bieszczady National Park and its closest surroundings. Among others: Aquila chrysaëtos, Aquila pomarina, Cir­caëtus gallicus, Circus cyaneus, Ciconia nigra, Bubo bubo, Strix uralensis, Prunella collaris. Quantitative data were collected by the method of stripe transect. The mean total density of birds from all recorded species in a mountain beech forest was 40.90 pairs/10 ha, in a dwarf beech forest 29.1 pairs/10 ha, on mountain meadows 7.35 pairs/10 ha. Fringilla coelebs, Erithacus rubecula, Troglodytes troglodytes, Phylloscopus sibilatrix, P. collybita, Sylvia atricapilla are the dominating species in forest communities. The greatest species diversity was recorded from the mountain beech forest (H’= - 3.44).
