Some Blood Parasites from Nebraska Birds

Abstract

The following observations on the protozoan genera Haemoproteus, Leucocytozoon, Plasmodium, and Trypanosoma, with notes on the immature nematode group Microfilaria, are based for the most part on material collected at Peru, Nebraska, during the spring and summer of 1935 and 1936. Eightynine different birds were examined representing nineteen families and fortyfour species. Of this group twenty-six were found to harbor one or more genera of blood parasites.
