Seventy‐eight strains of avian paramyxoviruses (PMV) were isolated from cloacal and/or tracheal swabs taken from 1,342 feral ducks, comprised of spot‐bill ducks, mallards, pintails, teals, falcated teals, wigeons and buffie‐heads, in Wakuya‐cho, Miyagi Prefecture, Japan, between 1976 and 1979. Five and a half percent of the ducks were positive for virus. Serological and structural characterization indicated that three different avian paramyxoviruses arc prevalent in the Japanese feral duck population. The first group of PMV was Newcastle disease virus (NDV), and in vivo pathogenecity tests in embryonated chicken eggs and 1‐day‐old chicks revealed that all the NDV strains isolated were avirulent. The second and most prevalent strain was closely related to PMV‐4, duck/Hong Kong/D3/75 strain. The viruses of the third group were recovered only from pintails. They cross‐reacted antigenically with PMV‐3 when antisera to the PMV‐3 reference strains, turkey/Wisconsin/68 and parakeet/Netherlands/449/75, were employed. However, no cross‐reaction was observed when antiserum to pintail/ Wakuya/20/78, the prototype of this group, was used. The viruses of the third group also differed in viral polypeptide profile from the reference strains of PMV‐3.
