抄録

Social behavior of the Japanese wood mouse was studied by trapping and by direct observation at two artificial feeding sites during the early part of the breeding season. Meetings were classified into the following five types : aggressive meeting, meeting with retreat, meeting with mutual flight, tolerant meeting and amicable meeting. Amicable meetings and meetings with mutual flight were observed only between opposite sexes. Males always expelled other males from the feeding site when they met, and a straight dominance hierarchy was observed, although their ranges overlapped rather randomly. The subordinate males had somewhat different activity rhythms from those of the dominant. On the other hand, ranges of females tended to be mutually exclusive, but females permitted other females to stay near the feeding site. All females had similar activity rhythms. The social order seemed to be related to the body weight, but males were dominant over females, even if the male was smaller than the female. Although males often took the bait together with females, no evidence that a male associated with a particular female was obtained.
