Thirty-eight shoveler ducks, Anas clypeata, were collected in the Rio Grande Valley, Hudspeth County, Texas. Nineteen species of helminths, six species of lice and a sarcosporidian, Sarcocystis rileyi, were recorded. Seventeen of the nineteen species of helminths were observed in fall migrants and twelve species were recorded from spring migrants. The nematode Alifilaria pochardi Ali, 1969, is a new host and American record.
