Feeding behavior of lake whitefish and lake herring in Torch Lake, Michigan

It is proposed that Haemoproteus nettionis (Johnston and Cleland, 1909) Coatney, 1936 be accepted as the correct name for the Haemoproteus of Anatidae. A list of synonyms and amended description of the parasite is given. Infections are reported from wood ducks (Aix sponsa) and from domestic ducks and geese, the last representing a new host record. Natural transmission was demonstrated at the Patuxent Research Refuge, Laurel, Maryland. Possible seasonal variation is suggested with active carriers present as early as mid-April among adult wood ducks and most active transmission occurring in June and early July with limited transmission earlier or later.
