green-winged teal, Anas crecca, parasites, hematozoa, helminths
Five helminths and one sporozoan were recovered from 21 hunter-killed green-winged teal collected from Lakin Slough in Guthrie County, Iowa during October and November of 1991. The sporozoan, Leucocytozoon simondi, was identified in blood smears from all 21 teal. The helminths recovered from the alimentary tract included three trematodes, Cotylurus flabelliformis, Echinostoma trivolvis and Zygocotyle lunata; a hymenolepid tapeworm; and one acanthocephalan, Corynosoma constrictum. The ecological factors associated with infection by these parasites are discussed.
