Bimonthly changes in home range size of seven mature roe deer Capreolu
s capreolus L. females were analysed over one year. Great stability of
home range size and high site fidelity was common to all females, whi
ch remained bimonthly within areas of 6.1-20.8 ha. Two groups of femal
es could be identified on the basis of bimonthly variations in their h
ome range sizes: females with larger areas (LHR females), who decrease
d their ranges in the birth season only, and females with smaller home
ranges (SHR females), who increased significantly their home ranges d
uring the rut. The most likely explanation is that the areas inhabited
by SHR females included high-quality food resources allowing survival
even in small home ranges. In the rut, SHR females may have expanded
their ranges to increase mating opportunities.
