Northern Shoveler (Anas clypeata) Science Article 1
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, Sancocystis nileyi, were recorded. Seventeen of the nineteen species of helminths were observed in fall migrants and twelve species were recorded from spring migrants. The nematode A/if ilania pochandi Au, 1969, is a new host and American record.
