Parasitic nematodes of 176 individuals of 15 bird species belonging to the order Anseriformes from Hokkaido, Japan were investigated. A total of 12 nematode species were obtained, namely Amidostomum anseris, A. acutum, Epomidiostomum crami, E. uncinatum, Tetrameres fissispina, Eucoleus contortus, Capillaria anatis, Baruscapillaria mergi, Contracaecum rudolphii, Echinuria uncinata, Streptocara crassicauda and Sarconema eurycerca. Among these, E. uncinatum (hosts: Anas platyrhynchos, A. poecilorhyncha, A. acuta, Mel. nigra) and E. crami (hosts: Anser albifroms, Ans. fabalis, C. cygnus, C. columbianus) were the first geographical records in Japan. There appeared to be strict host-parasite relationships between the wild swans/geese and A. anseris/E. crami, and between wild duck species and A. acutum/E. uncinatum, respectively.
