Abstract
From 1978 to 1981 in the Bavarian Alps (Southern West Germany) the home range and activity patterns of nine male red deer have been studied using radio-telemetry. The home range patterns definetely change with age. Younger stags first follow the patterns of their mothers, then often emigrate from these home ranges and establish new ones elsewhere. Except for the change in range at about 21/2 years of age, these patterns seem to be very constant in both spatial as well as seasonal position and the size of the home ranges. Winter and rutting ranges are relatively small, averaging 113 ha and 134 ha, respectively, whereas the mean size of the home ranges used from spring to autumn amounts to some 386 ha. Just as do the home range patterns, so also do activity patterns exhibit a marked annual cycle. The daily sum total of activity varies from about 9 h in winter to some 15 h in summer. The daily distribution of activity reveals a typical bimodal 24-h rhythm which in the course of the year also shows modifications according to the seasonally varying LD-ratio. In the discussion, earlier results on female red deer are compared to those of this study. Notable differences between sexes occur in the home range patterns and the annual cycle of daily activity.
