Abstract:
Forty-one bird species were found in the lower mountain forest zone on the northern slope of Babia Góra in the spring-summer seasons of 1987-1989. In these successive years 16, 22 and 19 species (25 species at all) were breeding in a 12-hectaresample plot set up in a beech wood belonging to the Fagetum carpaticum associacion and the density reached in these years was respectively 54.6, 75.8 and 67.5 pairs/10 ha. Fringilla coelebs, Erithacus rubecula and Sylvia atricapilla were dominant species in all those years and, besides, Certhia familiaris and Phylloscopus collybita in 1987 and Prunella modularis and Parus ater in 1988.
