| Summary: | other vole species, in captivity has a short-term activ-ity rhythm in daytime, with a period of circa two hours. Trapping records show that this rhythm exists also in field conditions, with the population in synchrony to some degree; a correlation of trapping frequency with vole predation by kestrels indicates that it reflects the true natural behaviour. 2. Lehmann's (1976) evidence in Microtus agrestis that the short-term activity rhythm is essentially a feeding rhythm is supported for the common vole by separate recording of wheel running, feeding and nestbox occupation. 3. The short-term rhythm is phase-locked to dawn. There is fair intraindividual constancy from day to day in the timing of meals, but interindividual varia- |
