Helminth parasites of the osprey, Pandion haliaetus, in North America
A total of 28 species of helminths (17 trematodes, 3 cestodes, 7 nematodes, and 1 acanthocephalan) was recovered from 17 ospreys ( Pandion haliaetus ) from the United States. Intensities of infection were low and no lesions were attributed to the parasites. Seven species appear to be specialists in ospreys, 2 species generalists in raptors, and the remainder generalists in other orders of fish-eating birds. Pandiontrema rjikovi , Diasiella diasi , and Contracaecum pandioni are reported for the first time from North America.
