Abstract

Ninety-nine crows (Corvus brachyrhynchos Brehm, 1822) including 37 adult males, 18 adult females, 4 adults of unknown sex, and 40 immatures were examined from twelve localities in Newfoundland. Ninety-eight percent of the crows were infected. Eighteen species of parasites were recovered; seven being new host records for North America. -- Four adult female ravens (Corvus corax Linnaeus, 1758) were also examined. Eight species of parasites were recovered; five being new host records for North America. -- The percentage infection, range of numbers, and the mean number of parasites per host is given for adult birds of each sex, and for immatures. Parasite species are discussed individually with regard to infection, host records, authorities used in specific determinations, and minor variations, if any, from the original descriptions.
