Wild birds in two adjacent locations of the Bukovské Vrchy Hills in the East Carpathians (Slovakia) were investigated for blood parasites in the post-breeding period. In 2001, 595 birds were investigated at Ruské. In 2003, 289 birds were investigated in Kurników Beskid. In Ruské, parasites of the genera Haemoproteus, Leucocytozoon and Plasmodium were found at prevalences of 21 %, 6 % and 0.5 %, respectively. In Kurników Beskid, the prevalences of infections with the parasites of genera Haemoproteus, Leucocytozoon and Trypanosoma were 17 %, 0.7 % and 0.3 %, respectively. Parasite species found in blood smears of the birds included Haemoproteus attenuatus, H. balmorali, H. belopolskyi, H. fringillae, H. picae, H. zosteropis, Leucocytozoon dubreuili, L. fringillinarum, L. majoris and occasionally also Plasmodium sp. and Trypanosoma sp. Except for H. fringillae, all found species of hematozoa are priority findings for Carpathians. This is the first report of finding of H. zosteropis in Hippolais icterina.
