Natural infections of Streptocara crassicauda and Streptocara incognita were diagnosed in four mallards (Anas platyrhynchos) from Red Rock Lakes National Refuge, Beaverhead County, Montana. Lesions at the junctions of the gizzard and proventriculus were associated with the nematodes, and resulted in debilitation, emaciation and death.
