Studies on the helminth parasites of the American herring gull ( Larus argentatus Pont.) in Newfoundland
Four hundred and ten herring gulls (128 chicks and 282 "adults"), obtained in Newfoundland, Canada, were examined for their helminth burden during 1966 and 1967. A total of 35 species of helminths were recovered during the survey (11 species of trematodes. 10 of cestodes, 11 of nematodes,...
