Abstract
This study provides quantitative data relating
short-term fluctuations in local weather conditions to various measures of
badger activity. These relationships were examined on a yearly, quarterly
and monthly basis using behavioural data collected from 65 animals
radio-tracked for a total of 518 nights in the suburbs of north-west
Bristol. The yearly pattern of badger activity was reflected in a strong
positive correlation between activity and daylength; in addition,
moonlight and the absence of cloud cover were shown to restrict both the
speed of travel and nightly range size, and to delay emergence. Looking at
the data on a quarterly basis, activity increased with increasing
temperature in the spring and autumn. Heavy rain reduced above-ground
activity in the autumn, and in the winter speed of travel increased with
wind speed. Nutritionally stressed adult females showed an increase in
activity during the shorter summer nights. However, in general, changes in
badger activity could not be readily predicted on the basis of the weather
variables measured. The significance of these relationships is discussed
in the light of the behaviour of badgers living in suburban Bristol.
