IN THE TUNDRA SWAN, CYGNUS COLUMBIANUS (ANATIDAE), FROM NORTH AMERICA
Abstract. Twelve tundra swans, Cygnus columbianus (Ord), from Nevada and one from New Mexico were collected and examined for schistosomes. Mature worms, determined as Allobilharzia visceralis, were found in 92 % of the swans, in the inferior mesenteric vein of the large intestine and its branches. I...
