The purpose of this study was to determine the incidence and intensity of blood parasites in the common crow (Corvus brachyrhynchos). The following observations on the protozoan genera Haemoproteus, Leucocytozoon, Plasmodium and Trypanosoma with observations on the nematode group microfilaria, are based entirely on materials collected at Auburn, Washington during the spring of 1970.
Despite the numerous studies on prevalence of blood parasites in various birds, there have been few attempts to study the relative incidence and intensity of haematozoa in blood and tissue smears taken from the common crow. So far as the author has been able to ascertain, no studies of this nature have been recorded previously from Western Washington.
