Social interactions of captive Apodemus microps Kratochvil et Rosicky, 1952 were studied in dyadic encounters. In neutral-cage conditions both sexes showed exceptionally high proportion of amicable behaviour ton average ca 30% of the total time) and very low proportion of agonistic behaviour (up to 2.1%), when compared to patterns reported in other Apodemus species. The high share of amicable behaviour cannot be simply explained by decreased aggression. Mice actively offered amicable acts to their unfamiliar conspecifics even during the short-time (ten-minute) encounters. This phenomenon may be interpreted as a cooperative strategy. However, the near absence of aggression in A. microps could be altered by specific social contexts: males, but not females, became mutually agonistic when tested in a home-cage or in the presence of a female.
