Abstract

Blood from 159 raptors of 9 species from the Hawk Ridge Nature Reserve, Duluth, Minnesota was examined for hematozoa. Accipiter striatus, A. cooperii, A. gentilis, Circus cyaneus, Buteo jamaicensis, B. platypterus, Falco peregrinus, F. columbarius, and Asio otus harbored both Leucocytozoon toddi and Haemoproteus. F. columbarius and Asio otus had only Leucocytozoon toddi, and one F. peregrinus was not infected. The prevalence of hematozoans was similar between ages classes of the sharp-shinned hawk (Accipiter striatus) and goshawk (Accipiter gentilis), but in the Cooper's hawk (Accipiter cooperii) immatures were more frequently infected than adults. There were no significant intersexual differences in infection rates for accipiters.
